Lygaeidae ; and larval stiletto flies Diptera: Adult pheromone trap catches and flush counts are correlated Funderburk et al. 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.
Activity extends from June to November, with the generations overlapping considerably and little evidence of breaks between generations. Elasmopalpus lignosellus Zeller Insecta: By late summer, most life stages are present in infested plants as generations overlap.
Moth Photographers Group – Elasmopalpus lignosellus –
On peanuts, this species mostly occurs in noneconomic densities, but sporadic outbreaks are associated with hot and dry climatic conditions Smith and Barfield Eggs hatch within a week, and early-instar larvae mine lower branches or begin to feed on stem and roots below the soil surface Dixon a. Lesser cornstalk borer, Elasmopalpus lignosellus Lignoselluxdamage to soybean. The female deposits nearly all her eggs below the soil surface adjacent to plants.
Lesser cornstalk borer required Cocoons measure about 16 mm in length and 6 mm in width. They spin silken tubes near the soil surface for elasmppalpus.
Adult male lesser cornstalk borer, Elasmopalpus lignosellus Zeller. Guide to insect borers of North American broadleaf trees and shrubs.
This will enable us to choose the best time to control this pest with greater precision. The most important pathogen appears to be a granulosis virus, but a Beauveria sp. Total larval development time varies widely, but normally averages about 20 days.
Lesser cornstalk borer has a number of weed hosts, such as: Corn, peanuts, and many other legumes and grasses are attacked, but plants in the grass family are preferred; attacks trees only ocassionally Dixon b, Luginbill and Ainslee Elawmopalpus are strong and active when disturbed and wiggle violently so that in some countries it is called the jumping borer Schaaf The species overwinters as a larva or pupa in the soil.
It is also found on the Bahamas. As seedlings begin to die, they may remain upright or fall over. When disturbed they flip about very rapidly.
Female moths oviposit eggs in late summer and fall in Kentucky Bessinwhile in Florida, we observed heavy oviposition in spring and early summer.
Distribution Back to Top The lesser cornstalk borer occurs widely in the western hemisphere and is known from much of the southern United States. It is based on the concept of “borer-days.
Elasmopalpsu page was last modified Populations tend to increase over the course of a season, so some ekasmopalpus can be avoided by early planting. Biomass was reduced in CP when plants were infested at any of the leaf stages, but sugar yield was reduced only when infested at the seven-leaf stage. Brownish moth with wingspan of 17 to 25 mm Luginbill and Ainslee Black locust, dogwood, tupelo, sycamore, pine, redcedar, Arizona cypress, and baldcypress.
Adults are generally brownish with narrow and elongate forewings with oblique distal margins.

Other parasitoids sometimes present include Bracon gelechiae Ashmead Hymenoptera: Removing soil from around the base of the seedlings reveals larval burrows girdling the stem and gall-like swelling and callus tissue at wound sites. Photograph by James F.
The pupal stage is 8 to 10 days. Soil tubes lignosellus by the lesser cornstalk borer, Elasmopalpus lignosellus Zeller. 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.
Elasmopalpus lignosellus – Bugwoodwiki
Normally the lignowellus is restricted to the basal region of stalks, including the belowground portion, and girdling may occur. The larva of the lesser cornstalk borer LCB liynosellus dark-colored with purple bands around its body.
Liquid insecticides directed at the base of host easmopalpus or granules applied to the soil can be effective but hot, dry conditions often reduce the longevity of registered insecticides. Plant death is not uncommon, and infested areas of fields often have a very thin stand. Close inspection of the soil near feeding sites exposes small tubes, composed of silk and soil particles, radiating from the injured seedling.
Photograph by Hardev Sandhu, University of Florida. The pupae are yellowish initially turning brown and then almost black just before adults emerge.
On peanuts, they will feed on any portion of the plant that contacts the soil. The estimated lower and upper developmental thresholds for total development were 9.
Pale yellowish green initially, gradually becoming dark brown, with six hooked spines on abdomen tip, and about 8 mm long.
