African Black Beetle larvae - apply before or at peak egg hatch for maximum control (typically mid-September). African black beetles have strong nocturnal flight activity, and disperse during their ‘roaming’ stage leading to crops becoming infested. Identification. A new balance is created so that the pest becomes less important. Summer, 2001. Lawn Pests & Control > Types of Lawn Pests; Black Lawn Beetle in Buffalo Lawn. Department of Primary Industries and Regional Development's Agriculture and Food division is committed to growing and protecting WA's agriculture and food sector. Both adults and larvae attack pastures and cereals. Other pests Classification Species category: Beetles & Weevils Scientific name: Heteronychus arator Description An adult is long, cylindrical with a shiny black/chestnut brown exterior; it typically reaches 15-25mm in length. They act in a targeted way and will not damage turf, non-target insects or wildlife. Larvae are susceptible to the entomopathogenic nematode, Growguards are used in some crops to protect new, plantings from herbicides and rabbits. The males have a thickened tarsus on front leg (to help them dig). These are late developers and fail to survive. Inspect susceptible paddocks prior to sowing. It has been present in Western Australia since the 1930s and occurs in the wetter coastal regions. Bulinski J, Matthiessen JN and Alexander R. 2006. The African black beetle is an introduced beetle that appears similar to cockchafers but generally occurs earlier in the year and is usually found on or under the soil. The plastic also assists with weed control. Department of Agriculture and Food Western Australia. To control African black beetle prior to planting potatoes, incorporate insecticide to a depth of 15cm. Biological Control of African Black Beetle (Heteronychus arator) in turf usin Ento opathogen c Nem todes. The black maize beetle (Heteronychus sanctae-helenae). PestNotes are information sheets developed through a collaboration between cesar and the South Australian Research and Development Institute (SARDI). Water repellence Delay autumn sowing until May as adults decrease their feeding activity during winter. The granules need to be covered by soil to protect them from environmental degradation. Lawn beetle symptoms are further aggravated by inadequate watering, poor fertilising and severe mowing. They are exempt from registration with the APVMA and control a range of damaging turf feeding larvae, including Argentine Scarab, Argentine Stem Weevil, African Black Beetle, Cockchafers and Billbug. mid-October), the adults may have already laid their eggs. Redheaded pasture cockchafers have a distinctive red head capsule. If the growguards are buried to about 5cm, they can also prevent attack by African black beetle adults. Biological: While there is a commercially available nematode (Heterorhabditis zealandica) for the biological control of African black beetle in turf and other high value crops, these are unlikely to be cost effective in broad acre crops. Best treatment for African Black Beetles For the control of African Black Beetle (adult stage) in lawns and turfed areas try Yates Baythroid Advanced Insect Killer for Lawns. CSIRO Publishing. Older plants usually survive, but remain weak. This should be repeated 10-20 times to get an estimate of larval numbers. Monitor crops and pastures in late spring to mid-summer for larval damage. Late stage larvae are 25-30 mm in length. High levels of flight activity indicate the possibility of crop invasion. If damage to the stem of grapevines near ground level has occurred, mounding soil around the base of affected plants has enabled some to recover. 4500, Agdex 241/622. However, susceptibility to wind and water erosion also need to be considered. Apply the higher rate for: up to 6 months protection. Nematodes live in the soil and spend their lives attacking the larvae and/or pupae of African black beetle and other soil-dwelling insects. These are late developers and fail to survive. For maximum effectiveness, soil temperature should be above 15°C with high soil moisture levels. It is native of Africa, now present in Australia and the North Island of New Zealand. African Black Beetle heteronychus arator . Selective control with minimum risk to turf, people and the environment is best practise pest control. African Black Beetle Heteronychus arator. They develop on or within the insect. This article was compiled by Sandra Hangartner, Garry McDonald (cesar) and Paul Umina (cesar). Damage can be caused by adults feeding on the stems of young plants either underground or above the soil surface, often killing growing points so that the central shoots wither and the plants die. August), the adults may not have become sufficiently active to be killed; if the spray is applied too late (e.g. incorporate insecticide to a depth of 15cm. 1994. 1 day WHP. The adult beetle is a rich chestnut colour when newly emerged, but changes to a shiny black, stout bodied beetle approximately 10-15 mm long. 2010. Soil-dwelling third instar larvae cause most damage to pastures by cutting of roots below the soil surface. Mounding may also be applicable for rejuvenating damaged blue gums, olive trees and other plants. Carnegie A … Viticulture spray guide for Western Australia, Australian Pesticides and Veterinary Medicines Authority, Biosecurity and Agriculture Management Act, Western Australia's agriculture and food sector, Casual, short-term employment and work experience. Acelepryn provides safe and effective control of black beetle while minimising the impact on the environment and non-target organisms, such as bees and earthworms. PestNotes may identify products by proprietary or trade names to help readers identify particular products. 2002. This should be repeated 10-20 times to get an estimate of larval numbers. The period from eggs to adults is approximately three to four months, while the adult lifespan is about ten months. Newly hatched larvae are about 5 mm long. ENs (Beneficial Nematodes) are the only non-organophosphate solution. Their raster is a transverse narrow slit (smiling grub). The period from eggs to adults is approximately three to four months, while the adult lifespan is about ten months. PRE-PLANT INSECTICIDES Chlorpyrifos 500EC For the control of African black beetle, wireworm and a wide range of other insect pests. Relying on beetles to crawl through treated soil is less effective. For detail on insecticide use in WA vineyards, consult the Viticulture Spray Guide. Relying on beetles to crawl through treated soil is less effective. African black beetle in vineyards. Acelepryn targets pests such as black beetle, stem weevil, cut worm and army worm. In Australia, some of the most productive agricultural land is naturally acidic (Scott et al., 2000). Fisher D and Learmonth S. 2001. Beetles are attracted to grassy areas or those with heavy mulching. Consider sowing less favourable pastures and crops such as legumes, oats and lucerne. For the control of African Black Beetle, Argentine Stem Weevil and other insect pests in Turf as per the Directions for Use Net Contents: 750 mL Approved pursuant to the HSNO Act 1996, Approval Code HSR007969 Syngenta Crop Protection Limited Tower 2, Level 7, 110 Symonds Street, Auckland. potential use for control of African Black Beetle larvae. Flights during summer to autumn can be observed as activity increases around lights on buildings etc. This consists of a plastic mesh sleeve placed over the root ball and along most of the stem of treelings. Design by Miek. Bulinski J and Matthiessen JN. Keep the paddock as bare fallow for as long as is feasible prior to planting. Adult redheaded cockchafers can be distinguished by their ovoid body and wing covers with deeply indented striations separated by distinct dots. Department of Agriculture and Food Western Australia. Shoots emerging below chewed stem (left) and individual tiller affected as shown by arrow (right) (Source: Copyright © Western Australian Agricultural Authority). Larvae are susceptible to the entomopathogenic nematode Heterorhabditis bacteriophora, which is native to New South Wales. Proceedings of the New Zealand Grassland Association 75, 235-240. http://www.grassland.org.nz/viewpublication.php?pubID=376, Micic S and Learmonth S. 2015. Eggs are laid in the soil in spring and hatch in two to five weeks depending on temperature. Pests. Proceedings of the Annual Congress - South African Sugar Technologists' Association. The adults are pink and black. August), the adults may not have become sufficiently active to be killed; if the spray is applied too late (e.g. Most of the organisms were general predators or pathogens with unpredictable or unclear effects on the population dynamics of H. arator. The alternative is to spray the lawn with a relatively new but very low toxic systemic chemical containing imidacloprid (Confidor, Bug Kill, Conquest and others). Larvae hatch and pass through three growth stages before pupating and emerging as adults between late December and early February. Systemic insecticide seed dressings applied to protect newly sowed crops have been effective in field trials against adult beetles. There is some evidence that liming in acid soil environments can reduce the survival of young black field beetle larvae. Adult redheaded cockchafers can be distinguished by their ovoid body and wing covers with deeply indented striations separated by distinct dots. Development of a cost-effective, pesticide-free approach to managing African black beetle (Heteronychus arator) in Australian eucalyptus plantations. The underside of these small black “bugs” reveals rusty brown markings that help distinguish it from other beetles. This technique is most relevant to controlling fly-in infestations late in the crop cycle. Should control of an infestation of beetles be required after transplanting vines, this can be achieved by drenching around the base of vines with an insecticide solution. If the growguards are buried toabout 5cm, they can also prevent attack by African black beetle adults. Use the higher registered rates for heavy infestations as it is particularly effective in reducing stem damage, which can kill plants. The beetles are of considerable economic importance because, while they attack cereals, they also attack a wide range of horticultural crops and long-term pastures. Other scarabs and cockchafer larvae, including the yellowheaded cockchafer, redheaded pasture cockchafer and other pasture scarabs. Biological Control. (Refer to Viticulture Spray Guide or consult InfoPest.). If applied correctly and vines are managed well, granules should be active for two years. Adhere to product label. While nematodes are a relatively expensive option, they are suitable for high value crops such as amenity turf. There are also black beetle-resistant endophytes now available in perennial ryegrass, such as AR37 (follow recommendations to avoid stock performance issues). Adhere to product label. However, the possibility of fly-ins also needs to be considered. Poor efficacy of the insecticide chlorpyrifos for the control of African black beetle (Heteronychus arator) in eucalypt plantations. This contrasts to black headedcockchafers where the larvae come to the surface to feed and are accessible to synthetic insecticides. Melbourne. See, PestNotes are information sheets developed through a collaboration between, https://www.daf.qld.gov.au/plants/field-crops-and-pastures/broadacre-field-crops/integrated-pest-management/a-z-insect-pest-list/african-black-beetle, black beetle-resistant endophytes now available, http://dpipwe.tas.gov.au/Documents/africanblackbeetle.pdf, https://www.agric.wa.gov.au/pest-insects/identifying-soil-beetle-pests?page=0%2C1. Habitat preference of African black beetle and other soil insect pests of maize in South Africa. Abstract The larval stage of African Black Beetle (Heteronychus arator) is a damaging Scarab pest of turf They also attack several cereal crops including barley, triticale and wheat. By this time the vines are large enough to no longer be susceptible to stem girdling by the beetles. Bailey PT. Larvae are generally present from late spring to mid-summer but may be found during winter. Adults remain sexually immature until spring when mating and oviposition occurs. Paul Umina (cesar), Sandra Hangartner and Garry McDonald (cesar). It’s time to panic only when there is more beetle than lawn visible. Check crops and newly sown pastures for the presence of adults and damage in autumn-early winter. Ladybird beetle adult (Coccinellidae sexmaculata) feeding on aphids. Developing a strategy for using entomopathogenic nematodes to control the African black beetle (Heteronychus arator) in New Zealand pastures and investigating temperature constraints Michael J. Wilson, Derrick J. Wilson, Andrea Rodgers, Philippa J. Gerard Four larvae per spade square is roughly equivalent to 100 larvae per m2. cesar and PIRSA will not be liable for any loss, damage, cost or expense incurred or arising by reason of any person using or relying on the information in this publication. This is an extremely rare occurrence. Maestro® 200SC For the control of wireworm, mole cricket, white fringed weevil and However, insecticide treatment would still be required to control the beetles. South African Farming, 26:299-302. African Black Beetle Print page . Plants considered less favourable to ABB include oats, and some broadleaved plants such as lupins. For current information on registered insecticides, consult the Viticulture Spray Guide, InfoPest and the Australian Pesticides and Veterinary Medicines Authority. The grubs feed on the roots of the grass, leading to, reduced ability of the grass to take up nutrients and water from the soil. Larvae live underground and are unlikely to be affected by foliar applications of insecticides. Monitor crops and pastures in late spring to mid-summer for larval damage. Larvae hatch and pass through three growth stages before pupating and emerging as adults between late December and early February. Biological Control of (Heteronychus arator) A replicated trial,in association with Dr Bedding commenced at The Peninsula Country Golf Club in early February 1999 on a site known to be infected with African Black Beetle larvae.A randomised complete block design was used with each plot 293 Royal Parade, Parkville General feeding, regular watering, aerating and scarifying are good maintenance practices. They have ‘C’-shaped bodies, six legs and a yellow-brown head capsule with noticeable black jaws. Black beetle persistence in Waikato and Bay of Plenty following the 2007-08 outbreak. sustainability through science & innovation. Matthiessen J and Learmonth S. 1991. Nil WHP. Poncho Plus® has recently been registered as a seed protectant against African black beetle and yellow headed pasture cockchafers in pastures. Because kikuyu is a favoured food plant that can sustain high beetle populations, consider removing it as early as possible prior to planting. African black beetle has one generation per year, but in some seasons the generation can take two years. Newly emerged African black beetle adults are brown and fairly soft, but within hours they harden and darken to a glossy black. Another form of physical control has been developed by and for the blue gum industry. Because beetle adults are such clumsy walkers, planting into black plastic mulch on slightly raised angled beds may help reduce the numbers of adult beetles that are able to walk to the base of plants. Taylor TA, 1951. These sleeves make it impossible for adult beetles to feed on stems of plants at ground level. Australia. If you observe 50-100 beetles wandering across your lawn don’t panic. African Black Beetle. It is at the limit of its climatic tolerance and is restricted to Waikato and Bay of Plenty northwards with a southward coastal extension into northern Taranaki and Gisborne. African black beetle has a horizontal opening while yellowheaded scarabs have a ‘Y” opening, as illustrated here. cases of high pest pressure. Treatment: It is important to treat for black beetle in the Spring, usually September, when the larvae are near the soil surface, and are easier to kill. https://www.agric.wa.gov.au/pest-insects/identifying-soil-beetle-pests?page=0%2C1. Crop Protection 21: 621-627. From above, the body sides are almost parallel and the wing covers have lightly indented longitudinal striations. Larvae prune or completely sever roots of perennial grasses and in severe cases where larval populations are high, pasture becomes patchy and can be rolled back like a carpet. Victoria 3052 Australia, privacy policy & terms | legal terms & conditions African bollworm caterpillar is initially pale green, sometimes with black dots, and a pattern of thin dark lines running along the body, the lines being darker around the second and third segments. Beetles exposed in the process of land preparation or by a winged ripper to expose soil and beetles, would assist in this form of pest management. This can be estimated by considering that 44 x 15cm square spade samples = 1 square metre. There is a good deal of variation in colour in this species. Biological Control Options The fungus Metarhizium bassiana (in Biogreen) may or may not work on African Black Beetle. Also controls Mole Crickets, Couch Mite, Ants, Armyworm, Cutworm, Webworm and the adult beetle stage of Billbug, Argentine Stem Weevil and Scarab. prevent attack by African black beetle adults. The resulting dead beetles are counted within two days of spraying. Growguards are used in some crops to protect newplantings from herbicides and rabbits. African black beetle larvae (left) (Source: SARDI); Adult (right) showing striations on wing covers (Source: Walker, K. (2007) African black beetle (Heteronychus arator) Updated on 11/25/2011 10:14:39 AM Available online: PaDIL - http://www.padil.gov.au). Delaying autumn sowing and increasing seeding rates, taking advantage of biological control and insecticide seed dressings can reduce damage. There are a number of agronomic options that may reduce the intensity of black beetle damage, particularly if they are a continual problem. Effective insect control requires an in depth understanding of life cycle with sensible turf culture and targeted chemical control. When transplanting grapevines, a slow-release insecticide-incorporated polymer granule can be applied around the base of the young vines. Other organophosphate insecticides and insecticides from other activity groups are also registered for use. When considering this option assess the susceptibility of the paddock to wind and water erosion. Late stage larvae are 25-30 mm in length. Biosecurity fact sheet. Larvae are generally present from late spring to mid-summer but may be found during winter. While there is a commercially available nematode (Heterorhabditis zealandica) for the biological control of African black beetle in turf and other high value crops, these are unlikely to be cost effective in broad acre crops. Crop Protection 25: 1161-1166. This consists of a plastic mesh sleeve placed over the root ball and along most of the stem of treelings. Four larvae per spade square is roughly equivalent to 100 larvae per m, Chlorpyrifos is registered in maize however no other foliar insecticide is registered for African black beetle control in broadacre crops. About African Black Beetles. 2007. Water the lawn A major pest in turf, most damage is caused by adults feeding on the underground stems of young plants, often killing growing points so that the central shoots wither and the plants become dead-hearted. These sleeves make it impossible for adult beetles to feed on stems of plants at ground level. Tasmanian Department of Primary Industries, Parks Water and Environment. Beetle densities in excess of 10 per square metre may result in significant crop damage, but control may be warranted with densities of five per square metre or less (https://www.daf.qld.gov.au/plants/field-crops-and-pastures/broadacre-field-crops/integrated-pest-management/a-z-insect-pest-list/african-black-beetle). 17/91, Agdex 622, Agriculture Western Australia, Perth. In this case, the aim is to kill the black beetle larvae in spring well before they begin damaging your lawn by feeding on their roots. Having established the risk of damage by African black beetle, the area to be planted should be kept as bare fallow for as long as is feasible. Remedial action should be considered if there are more than three to six beetles per square metre in a paddock, or 5% or more of grapevines with beetles. Larvae prune or completely sever roots of perennial grasses and in severe cases where larval populations are high, pasture becomes patchy and can be rolled back like a carpet. If the growguards are buried to. © cesar pty ltd African black beetle larvae are soil dwelling and are typical white, soft-bodied scarab grubs. Insect Pest. Biological Control While a range of natural enemies and pathogens infecting H. arator have been identified, attempts at applying them in biological control have been unsuccessful (Cameron and Thomas, 1989). Control options - No synthetic insecticides have given effective economical control of redheaded cockchafers. A shortened version of the URL, helpful when communicating the URL over email or verbally. Inspect susceptible paddocks prior to sowing by digging to a depth of 10-20 cm with a spade and counting the number of larvae present. Native to Africa, these little black beetles are common agricultural pests in Australia and New Zealand. African black beetle is difficult to control as the soil acts as a protective blanket, and makes it difficult to judge pest abundance. Sprays can be applied to marked areas before planting, or the base of tagged grapevines across a block after planting. Because beetles are clumsy walkers, they accumulate in pitfall traps or sharp-sided plough lines. Volume 93, February 2016, Pages 1-7. Adult beetles occur no deeper than 15cm in soil, and are usually just below the soil surface. A sporadic agricultural pest found in Western Australia, South Australia, Victoria, New South Wales and Queensland, the African black beetle has not been recorded in Tasmania. mid-October), the adults may have already laid their eggs. The abdomen towards the rear is generally swollen and darker in colour. Adult flight activity can be monitored during summer or autumn by using light traps, or observing activity around lights near buildings and street lights. Adults can be found on or under the soil surface, to a depth of about 15 cm. Newly hatched larvae are about 5 mm long. Any research with unregistered pesticides or products referred to in PestNotes does not constitute a recommendation for that particular use. Adults remain sexually immature until spring when mating and oviposition occurs. Spade sampling across a paddock can be used to gauge their abundance. Larvae live underground and are unlikely to be affected by foliar applications of insecticides. Increasing seeding rates is a useful option in paddocks where the pest is anticipated to cause damage. ... it is known as classical biological control. In susceptible regions of WA (primarily in the higher rainfall areas adjacent to the south-west and southern coasts), consider monitoring for African black beetle adults prior to planting. Bulletin No. Soil invertebrates in 1997. The great thing about Acelepryn in comparison to other pesticides, is that it’s preventative. No person should act on the basis of the contents of this publication without first obtaining independent, professional advice. Larvae can be distinguished from other yellowheaded scarabs (Sericesthis species) by their anal opening at the tip of the abdomen (raster). 109-113. Damage by these beetles and their larvae can be reduced by delaying autumn sowing, or applying insecticide seed treatment. What to Control. Toit HA Du, 1997. Pests of field crops and pastures: identification and control. Consider removing kikuyu grasses well prior to seeding as this grass is a favoured food plant for black beetle and can sustain high beetle populations. Diseases and Pests – Grape Production Series Number 1, Winetitles, Adelaide. The grubs have distinctive orange spiracles along abdomen and thorax. Adults may be killed before they lay eggs during spring, however monitoring for the presence of adults is critical. African black beetle. The same technique can be used to monitor for the need to retreat as described above. Also consider applying insecticide prior to a light rain event, as the insecticide will be washed from the soil surface to a depth of 15cm (where adults and larvae occur). Adults are shiny black, slow moving and have a cylindrical body that is approximately 12-14 mm long. http://research.agwa.net.au/wp-content/uploads/2012/09/RT-99-8-African-Black-Beetle-in-Vineyards.pdf, Gerard PJ, Bell NL, Eden TM, King WM, Mapp NR, Pirie MR and Rennie GM. Sentinel drenching with an insecticide toxic to adults can also be used to assess presence. The Americans are using strains of Bacillus thuringiensis for scarab grub control, but again there is no A unique liquid formulation of tri-basic copper sulphate for control of early blight and late blight. Adults may be killed before they lay eggs during spring, however monitoring for the presence of adults is critical. If beetles exceed the thresholds suggested above, consider the following control techniques. If the spray is applied too early (e.g. Need help identifying insects? Black beetle is an African species but has been present in New Zealand for several decades. Black Lawn Beetle can be a problem for owners of all lawn types, including Buffalo grass lawns like Sapphire, Prestige & Palmetto.. A native of Africa, the Black Lawn Beetle goes through various life stages, each of which can cause at least some damage to our lawns. The material provided in PestNotes is based on the best available information at the time of publishing. Birds such as guinea fowl, chickens and ducks are used increasingly to control of a range of pests including adult beetles, wingless grasshoppers, garden weevil and snails. This technique may be suitable for other crops where planting material is small enough to be placed in the sleeves, such as bare-rooted vine transplants and olive treelings. If the spray is applied too early (e.g. Page last updated: Wednesday, 1 July 2020 - 2:39pm, In susceptible regions of WA (primarily in the higher rainfall areas adjacent to the south-west and southern coasts), consider monitoring for African black beetle adults. Example of pitfall trap to monitor Africa black beetle adults, Base drenching grapevines to control African black beetle, Apparatus to spread mesh sleeves to protect blue gum treelings from African black beetle adults, Treelings enclosed with plastic mesh sleeves. In: Allsopp PG, Rogers DJ, Robertson LN, eds. Some of the earliest remedies used to control African black beetle in South Africa included manure traps, sprinkling with salt, and application of lime into the soil, the latter being the only one reported as successful (Ormerod and Janson, 1889). African black beetles are normally associated with damage to long-term pastures and grasses, turf and some horticulture crops. Some of these methods may also be relevant for similar pests in other crops, provided that the insecticide is registered. Resident populations of African black beetle can be reduced by applying insecticide to the soil surface in late winter, when the crawling activity of the insect increases. Argentinian Scarab larvae - apply before or at peak egg hatch for maximum control (typically mid-December). Adults grow into 12 to 15 mm shiny black beetles. African Black Beetle, Farmnote No. Use a rotary hoe to ensure thorough mixing, as this maximises direct contact of the insecticide with the beetles. These are seldom seen in the home lawn but their damage is a lot more dramatic than our old friend, the African Black Beetle. http://dpipwe.tas.gov.au/Documents/africanblackbeetle.pdf. The abdomen towards the rear is generally swollen and darker in colour. However, susceptibility to wind and water erosion also need to be considered. A black beetle the size of a sesame seed is killing South Africa's trees, and no one knows how to stop it. Biology. The scarab beetle grubs rather than the adult beetle cause most turf injury. Identifying soil beetle pests - African Black Beetle. Lifecycle, critical monitoring and management periods for the African black beetle (Source: cesar and QDAFF). Another form of physical control has been developed by and for the blue gum industry. This technique may be suitable f… Developing a strategy for using entomopathogenic nematodes to control the African black beetle (Heteronychus arator) in New Zealand pastures and investigating temperature constraints.
