Environmental Entomology 18: 447-458. Mature larvae grow to 1 ½ inches long. The black cutworm species ranges from light gray to black in color, and larvae are 1-1/2 inches long when fully grown. The container is baited with fresh plant material and/or bran, and with vermiculite so the larvae can attain shelter. Showers WB, Smelser RB, Keaster AJ, Whitford F, Robinson JF, Lopez JD, Taylor SE. However, light traps are not consistently efficient. Journal of Economic Entomology 77: 491-494. The eggs normally are deposited in clusters on foliage. The Black Cutworm Moth rests on Greater Burdock in a wetland meadow on the banks of the River Mole at Betchworth, Surrey Thursday 1st August 2013. Credit: Photo by Lindsay Constable /Alamy Live News Betchworth, Surrey, UK. Adult: The adult is fairly large in size, with a wingspan of 40 to 55 mm. devitt, j.j.b. Abdel-Gawaad AA, El-Shazli AY. They are active at night and spend the day under debris on the soil away from light. Abstract. The entire body has a distinctive bronze sheen. Despite the frequency of occurrence, however, it tends not to appear in great abundance, as is known in some other cutworms and armyworms. Metal or waxed paper containers with both the top and bottom removed can be placed around the plant stem to deter consumption. Pupae have been known to overwinter as far north as Tennessee, but apparently are incapable of surviving farther north. The hind wings are whitish to gray, and the veins marked with darker scales. The wingspan varies from 38 to 51 mm. Missouri Pest Monitoring Network Black Cutworm I.D. Survey and phenology of cutworms (Lepidoptera: Noctuidae) infesting field corn in the midwest. 1982b. Black cutworm (Agotis ipsilon) Variegated cutworm (Peridroma saucia) . Figure 3. Cutworms and armyworms are the larvae (caterpillars) of several species of night-flying moths in the family Noctuidae. In recent years, adequate methods for assessing the toxicity of insecticides to the black cutworm have been developed (Begg and Harris, 1958; Begg et al., in preparation; Harris and Mazurek, 1961).However, with the exception of the works by Crumb (1929) and Satterthwait (1933), … Larvae usually remain on the plant until the fourth instar, when they become photo-negative and hide in the soil during the daylight hours. The egg bears 35 to 40 ribs that radiate from the apex; the ribs are alternately long and short. Large larvae burrow in the soil, and are difficult to observe. The larvae are known as "cutworms" because they cut plants and other crops. Three types of sensilla were found on the proboscis: sensilla chaetica, sensilla basiconica, and … Relatively large with wingspans of 1.5-2.0 inches; Brownish color; Single, black, dagger-like mark on each forewing The head is brownish with numerous dark spots. Larval body length is reported to be 3.5, 5.3-6.2, 7, 10, 20-30, 30-45, 50, and 50 mm for instars one through eight, respectively. On some individuals, the dorsal region is slightly lighter or brownish in color, but the larva lacks a distinct dorsal band. Boughton,AJ, Lewis LC, Bonning BC. 2nd August, 2013. Black cutworm larvae vary in size from 1/8 inch (3 mm) when newly hatched to 2 inches (50 mm) when fully grown. 2001.Potential of Agrotis ipsilon nucleopolyhedrosis for suppression of the black cutworm (Lepidoptera: Noctuidae) and effect of an optical brightener on virus efficacy. Larvae readily accept insecticide-treated bran and other baits Application of systemic insecticides to seeds also provides some protection against larval injury. Among the wasps known to attack this cutworm are Apanteles marginiventris (Cresson), Microplitis feltiae Muesebeck, Microplitis kewleyi Muesebeck, Meteorus autographae Muesebeck, Meterorus leviventris (Wesmael) (all Hymenoptera: Braconidae); Campoletis argentifrons (Cresson), Campoletis flavicincta (Ashmead), Hyposoter annulipes (Cresson), and Ophion flavidus Brulle (all Hymenoptera: Ichneumonidae). action of mouthparts during feeding in the dark-sided cutworm, euxoa messoria (lepidoptera: noctuidae) - volume 117 issue 3 - b.d. Autumn Smart and Dr. Judy Wu-Smart) on being awarded a $10,000 national Christi Heintz Memorial Scholarship by, Apply to the University of Nebraska–Lincoln, Give to the University of Nebraska–Lincoln, Institute of Agriculture and Natural Resources, Emerald Ash Borer Look-Alike Insects Sheet, Research Publications on UNL Digital Commons, Entomology Hall (Plant Industry Building) History, College of Agricultural Sciences and Natural Resources. The black cutworm is the species most likely to da… More than 45 days are required for eggs to develop into larvae and adult moths. Bronzed cutworms are dark brown to black on the upper side of the body and paler on the underside. Caterpillars in this group are characterized by three pairs of legs situated behind the head, fleshy prolegs and a distinct head. However, in Missouri, USA, there are reports of 69% parasitism, so natural enemies probably exact a significant toll on cutworm populations. Aluminum foil can be wrapped around the stem to achieve a similar effect. Figure 1. Subterranean damage is very injurious. Temporal and spatial distribution of black cutworms in midwest field crops. Lateral view of the larva of a black cutworm, Agrotis ipsilon (Hufnagel). Cutworm and armyworm larvae are only occasional pests of turfgrasses in Nebraska. Effect of parasitism by, Showers WB, Keaster AJ, Raulston JR, Hendrix III WH, Derrick ME, McCorcle MD, Robinson JF, Way MO, Wallendorf MJ, Goodenough JL. Apple JW, 1967. When disturbed, cutworms curl up into a tight C-shape. Use of netting or row covers, in addition to larval barriers, should prove more effective. Includes . Insects have a range of mouthparts, adapted to particular modes of feeding.The earliest insects had chewing mouthparts. Many species of cutworms are part of the Noctuidae family. Photograph by John L. Capinera, University of Florida. Larvae are effectively captured in baited containers if the vermiculite is not too near the surface, and catches are enhanced if a screen cylinder, which provides a visual stimulus to the cutworms, is suspended above the baited container. Survival and development of black cutworm (. Nonetheless, they inoculate the area and allow production of additional generations, including moths that disperse north into Canada. The number of generations occurring annually varies with weather conditions. Surface features of mouthparts of mature larvae of the black cutworm, Agrotis ipsilon (Hufnagel), were examined using the secondary emission mode of The dark gray to black larvae have a greasy appearance and a grainy texture. Long distance dispersal of adults has long been suspected in Europe, China, and North America. 1989. Duration of the larval stage is normally 20 to 40 days. The preference by black cutworm for weeds is sometimes quite pronounced, and crops will be attacked only after the weeds are consumed. Other parasitoids known from black cutworm include flies often associated with other ground-dwelling noctuids, including Archytas cirphis Curran, Bonnetia comta (Fallen), Carcelia formosa (Aldrich and Webber), Chaetogaedia monticola (Bigot), Eucelatoria armigera (Coquillett), Euphorocera claripennis (Macquart), Gonia longipulvilli Tothill, G. sequax Williston, Lespesia archippivora (Riley), Madremyia saundersii (Williston), Sisyropa eudryae (Townsend), and Tachinomyia panaetius (Walker) (all Diptera: Tachinidae). When disturbed, the caterpillars curl up tightly into a C-shape. Black cutwor… Females may deposit 1200 to 1900 eggs. 1983. Larvae feed along or below the soil line, causing wilting due to root damage or, more characteristically, cutting the plants off at the soil line. 2001). Recapture of marked black cutworm (Lepidoptera: Noctuidae) males after long-range transport. Dorsal view of the larva of a black cutworm, Agrotis ipsilon (Hufnagel). The black cutworm monitoring and forecasting program is coordinated by the MU-IPM Program, in cooperation with the MU Commercial Agriculture Program's climatologists and programmers with the MU AgEBB (Agriculture Electronic Bulletin Board).The MU IPM program supports volunteer trappers in approximately 25 Missouri counties (). Adults (moths) are robust, drab-colored and hairy with wingspans up to 1 1/2 inches across. The moth gets its scientific name from black markings on its forewings shaped like the letter "Y" or the Greek letter upsilon. Journal of Economic Entomology 84: 879-885. Cutworms feed at night and can often be found during the day hidden in the soil near the base of the damaged plants. Thus, it is often recommended that weeds not be tilled or treated with herbicide until larvae have matured. Agrotis ipsilon, the dark sword-grass, black cutworm, greasy cutworm, floodplain cutworm or ipsilon dart, is a small noctuid moth found worldwide. Story RN, Keaster AJ, Showers WB, Shaw JT. Pupa: Pupation occurs belowground at a depth of 3 to 12 cm. In these latter instars they also tend to sever plants at the soil surface, pulling the plant tissue belowground. Adults do no damage to turf. Light traps are most effective in the summer and autumn, but the late season generations generally pose little threat to crops. Their effectiveness is related to soil moisture conditions. However, larvae will feed aboveground until about the fourth instar. Head capsule widths are very similar for instars one through four, but thereafter those individuals that display eight or nine instars show only small increments in width at each molt and eventually attain head capsule sizes no larger than those displaying only six or seven instars. It has a wingspan of 1.5 to 2.12 inches long. However, in 1999 the Agrotis nucleopolyhedrosis virus was identified, and seems quite lethal to young larvae (Boughton et al. However, larvae can be sampled with bait traps, and this is most effective prior to emergence or planting of seedlings. Journal of Economic Entomology 94: 1045-1052. Deciduous trees and shrub such as linden, wild plum, crabapple, and lilac are especially attractive to moths. However, light traps are not very effective during the spring flight, and underestimate early season. Mean duration of instars one through six was reported to be 6.0, 5.0, 4.6, 4.3, 5.6, 4.0 days, respectively, at 22°C. Corn at the one-leaf stage is very susceptible to damage, but that by the 4 or 5-leaf stage plant yield was not reduced by larval feeding. Adults feed on nectar from flowers. The larva is the damaging stage and damages plant tissue by feeding with chewing mouthparts. Eggs may be laid even before crops are planted. The black cutworm, Agrotis ipsilon (Hufnagel), has a wide host range, feeding on nearly all vegetables and many important grains, particularly corn. Survey and Trapping. Cutworm larvae are active now (seen early as late January into April). Black Cutworm – Agrotis ipsolon (Hufnagel)Family: Noctuidae, Order: Lepidoptera Indentification: Adult -The moth is characterized by long, narrow, usually dark forewings which are pale near the tips. Larvae tend to be cannibalistic. This may be due, in part, to the tendency of moths to oviposit on weeds; weedy fields tend to have higher cutworm populations. The term ‘cutworm’ refers to the habit that these worms have of chewing right through the stem of a plant. Cutworms are found throughout North America. BCW larvae pass through seven instars. Black cutworm is capable of feeding on a wide range of vegetable crop, including both direct-seeded and transplanted sweet corn, tomatoes, vine crops and cole crops. Harris CR, Mazurek JH, White GV. 1962b. Here we examined the proboscis sensilla of the black cutworm Agrotis ypsilon (Rottemberg), a cosmopolitan agricultural pest of great economic significance, using scanning electron microscopy. 1971. Identification Black cutworm larvae are greyish-black with a paler underside. The young cutworm feeds on plant material without cutting off the stems or leaves but later becomes a true cutworm when it begins to cut off foliage and carry it back to its burrow. Pheromone traps are more effective during the spring flight, when larvae present the greatest threat to young plants. In the spring, the adult moths can be blown long distances in storms along the low level jet stream. 1991. It annually reinvades temperate areas, overwintering in warmer or subtropical regions. The forewing, especially the proximal two-thirds, is uniformly dark brown. Pest description and crop damage The black cutworm moth is a uniform dark brown with a lighter irregular band near the wing tips and a distinct black dash. The life history of the black cutworm, Schoenbohm RB, Turpin FT. 1977. Environmental Entomology 11: 1019-1022. Numerous convex skin granules give the larvae an overall shiny and "greasy" appearance. Moths select low-growing broadleaf plants preferentially for oviposition, but lacking these will deposit eggs on dead plant material. Rather, such pathogens as viruses, fungi, bacteria, and protozoa from other insects have been evaluated for black cutworm susceptibility; in most cases only relatively weak pathogens have been identified. An entomopathogenic nematode, Hexamermis arvalis (Nematoda: Mermithidae), is known to parasitize up to 60% of larvae in the central USA. Timing is important, however, because prolonged competition between crop and weed plants can reduce crop yield. Similar displacement to the south and southwest has been documented in the autumn. Corn and tobacco are two of its preferred crops. The overwintering biology of the black cutworm. Duration of the pupal stage is normally 12 to 20 days. Larval development is strongly influenced by temperature, with the optimal temperature about 27°C. This publication provides turfgrass management professionals and golf course superintendents in Indiana and throughout the Midwest with information to help them 1) properly identify the black cutworm, 2) understand black cutworm biology, 3) recognize black cutworm damage, and 4) formulate safe and effective black cutworm management strategies. Thus, the phenology of black cutworm remains uncertain, or perhaps is inherently variable due to the vagaries associated with long range dispersal. Entomopathogenic nematodes (Nematoda: Steinernematidae and Heterorhabditidae) will infect and kill black cutworm larvae, but their populations normally need to be supplemented to realize high levels of parasitism. Cutworms feed on many plant species. aizawai, which confers resistance to the European corn borer (Ostrinia nubilalis) and certain other lepidopteran pests such as the pink borer (Sesamia spp. The black cutworm feeds on a wide range of field and garden crops. Close examination of the larval epidermis reveals that this species bears numerous dark, coarse granules over most of its body. The upper surface has three narrow yellow stripes and a broad white-yellow stripe running down each side. Black cutworm has been known, at times, as "overflow worm," due to its tendency to be abundant and damaging in fields that have been flooded by overflowing rivers. Adult black cutworm, Agrotis ipsilon (Hufnagel). An ectoparasitic nematode, Noctuidonema guyanense parasitized the adult stage, but its impact is uncertain. In contrast, reduced tillage cropping practices, which often produce higher weed populations, seem to result in increased abundance of black cutworm and higher levels of cutting in corn. This cutworm apparently does not overwinter well in the commonwealth except possibly in years with very mild winters. Black cutworm larvae vary in color from light gray to black and are about 1 ½ inches long when fully grown. Among the weeds suitable for larval development are bluegrass, Poa pratensis; curled dock, Rumex crispus; lambsquarters, Chenopodium album; yellow rocket, Barbarea vulgaris; and redroot pigweed, Amaranthus retroflexus. Based on light trap collections, moths are reported to be abundant in Arkansas, USA (a warm climate) during May-June and September-October, and in New York, USA ( a cool climate), they occur mostly in June-July. For information on turfgrass identification, weed, disease, and fertility manag… Typically, the front wings are darker than the hind wings and have various patterns of light and dark markings. Busching MK, Turpin FT. 1976. In the midwestern USA it is considered to be a serious corn pest. In appearance, the larva is rather uniformly colored on the dorsal and lateral surfaces, ranging from light gray or gray-brown to nearly black. Specialization has mostly been for piercing and sucking, although a range of specializations exist, as these modes of feeding have evolved a number of times (for example, mosquitoes and aphids (which are true bugs) both pierce and suck, however female mosquitoes feed … Photograph by John L. Capinera, University of Florida. Duration of the egg stage is three to six days. 1984. 1982a. Common Name: Cutworm Scientific Name: Varies Order: Lepidoptera Description: Caterpillars are dingy, grayish-black and smooth-skinned that may reach 1 ½ inch in length. Studies on the common cutworm. Story RN, Sundstrom FJ, Riley EG. Once the fourth instar is attained, larvae can do considerable damage by severing young plants, and a larva may cut several plants in a single night. Head capsule widths are about 0.26-0.35, 0.45-0.53, 0.61-0.72, 0.90-1.60, 2.1-2.8, 3.2-3.5, 3.6-4.3, and 3.7-4.1 mm for instars one through eight, respectively. Various trap designs have been studied, but many employ a container sunk into the soil with the upper lip at the soil surface. Larvae … Studies in the United States demonstrated northward displacement of moths during the spring in the range of 1000 km in two to four days when assisted by northward flowing wind. Adults are gray moths that have a series of distinctive dark markings on their forewings (including a dagger-shape on each outer forewing) and lighter colored hind wings. The distribution of larvae in the spring is random. Overwintering has been reported to occur in the pupal stage in most areas where overwintering occurs, but larvae persist throughout the winter in Florida, USA, a subtropical environment. Smelser RB, Showers WB, Shaw RH, Taylor SE. 3) Beak 4-segmented; adult body and legs black with white fore wings, each with a black triangular spot at the middle of the outer margin; immature body red to black with first two abdominal segments, legs and antennae pale yellow; older instars more dark red to black with a white spot between wing pads on abdomen, and black legs; 1/8 to 3/16 in. Story RN, Keaster AJ. Ventrally, the larva tends to be lighter in color. Thus, moths collected in the central region of USA in March and April are principally dispersing individuals that are past their peak egg production period. Tubercles on the body are paired, but uneven in size. The first appearance of moths in Ontario is usually in mid-April. Black cutworm infestations in potato fields are unpredictable, and damage varies from field to field and from year to year. When disturbed, the caterpillars curl up … 2.2A). Those arthropods that feed directly on host tissues generally retain the chewing-type mouthparts like those of cockroaches (Fig. Archer TL, Musick GL, Murray RL. The black cutworm is dark gray to black with a pale stripe down the back, but with few other distinguishing markings. In the home garden, barriers are sometimes useful to prevent damage to seedlings by cutworms. Black Cutworm. Soil is an unsuitable oviposition site. Predatory ground-dwelling insects such as ground beetles (Coleoptera: Carabidae) apparently consume numerous larvae. After the pupal stage, adult moths emerge and lay eggs on surrounding weeds, patches of grass and crop residue. Influence of sweet corn cultivar, planting date, and insecticide on corn earworm damage. Eggs are white at first, later turning brown. 1980. ), … Story RN, Keaster AJ. Moths may be carried several hundred miles in just a few nights by strong southerly winds. The pupa is 17 to 22 mm long and 5 to 6 mm wide, and dark brown. Black cutworm has a wide host range. 1983. Larvae parasitized by Meteorus leviventris (Wesmael) consume about 24% less foliage and cut about 36% fewer seedlings, so considerable benefit is derived from parasitism in addition to the eventual death of the host larva. Duration of the life cycle is normally 35 to 60 days. Oviposition preferences of black cutworm moths among various crop plants, weeds, and plant debris. Other known hosts include asparagus, bean, beet, cabbage, castor bean, cotton, grape, lettuce, peanut, pepper, potato, radish, soybean, spinach, squash, strawberry and tomato. It is more widespread, and damaging, in the northern hemisphere than the southern hemisphere. Adult populations can be monitored with both blacklight and sex pheromone traps. Black cutworms are a common corn pest throughout the Corn Belt and in the South. Larva: There are five to nine instars, with a total of six to seven instars most common. In all other lepidopteran families, the mouthparts are vestigal or form a tubular proboscis that lies coiled like a watch ... adults are reddish-orange with black and white markings. They are active at night and spend the day under debris on the soil away from light. Apple JW, 1968.
