Brownish moth with wingspan of 17 to lignoseellus mm Luginbill and Ainslee Content is available for non-profit, educational use under our Copyright Agreement. Such conditions are optimal for mating and oviposition. Feeding lignoseklus lesser cornstalk borer, Elasmopalpus lignosellus Zeller Lepidoptera: Feeding by larvae on woody tree seedlings is characterized by surface or subcortical burrowing and girdling and often results in gall-like swellings and callus tissue around the feeding site Snyder At rest, the female moth is often charcoal-colored Biddle et al.

Thus, tunnels often radiate out from the stem of the food source, just below the soil surface.

Duration of the egg stage is two to three days. Insecticides applied for suppression of lesser cornstalk borer are usually applied in a granular formulation in the seed furrow or in a band over the seed bed, using restricted pesticides according to label recommendations.

Bombyliidaeand Invreia spp. Throughout the linosellus half of the United States but most damaging in sandy soil along the south Atlantic and Gulf Coasts. Crops that are grown in late spring and early fall in northern Florida soybeans, peanuts, and grain sorghum are candidates for damage by lesser cornstalk borer, due to their favorable host status and exposure to high populations of lesser cornstalk borer Tippins Eggs are generally deposited singly on the upper and lower sides of leaves, at any point along the stem, and in soil just below the surface with grains of sand adhering to them.

Adults are generally brownish with narrow and elongate forewings with elazmopalpus distal margins.

Natural enemies generally did litnosellus greatly affect population levels of lesser cornstalk borer, due to its subterranean habits, silken webbing, and sporadic nature.

Among the predators thought to be important mortality factors are a ground beetle, Plilophuga viridicolis LeConte Coleoptera: Smith and Johnson constructed life tables for populations in Texas, and identified survival of large lesser cornstalk borer larvae as the key element in generation survival, but the causative factor remains unidentified. Elasmopalpus Adult male Adult female Scientific classification Kingdom: Close inspection of the soil near feeding sites exposes small tubes, composed of silk and soil particles, radiating from the injured seedling.

The mature larvae are bluish green, but tend toward reddish brown with fairly distinct yellowish white stripes dorsally.

Elasmopalpus lignosellus

Will Hudson, University of Georgia. Mature larva of the lesser cornstalk borer, Elasmopalpus lignosellus Zeller. Weather Back to Top Lesser cornstalk borers seem to be adapted for hot, xeric conditions, and therefore tend to be more abundant and damaging following unusually warm, dry weather.

Note wilting due to stalk feeding by larvae. Based on these results, we can forecast the different stages of lesser cornstalk borer at different epasmopalpus in sugarcane. Larval populations are aggregated, and can be separated from soil by sieving or flotation Mack et al.

Views Read Edit View history. They leave the tunnel to feed in the basal stalk area or just beneath the soil surface, returning and constructing new tunnels as they mature. Pupae are about 8 mm long and 2 mm wide. A single female can oviposit about eggs Capinerawith a report of up to eggs Biddle et al.

The larval stage causes damage when it lignosellux upon, and tunnels within, the stems of plants. Elasmopalpus lignosellus Zeller Insecta: Our recent observations suggest that mulching may reduce incidence of lesser cornstalk borer attack. Larvae tunnel into the crown of host plants, severely weakening large plants and often killing young seedlings.

Larval lengths are about 1.
