This study showed that P elaeisis can be reared on P denticulata pupae as an alternative host to produce this parasitoid for release in biological control programs of lepidopteran
pests of eucalyptus.
MNH-93 (a good yielding local cotton variety but susceptible to lepidopterans
insect pests) was transformed with Bacillus thuriengenesis gene (cry1Ab) using Agrobacterium tumefaciens strain C58[C.
Vip3A, a novel Bacillus thuringiensis vegetative insecticidal protein with a wide spectrum of activities against lepidopteran
I have wings looking like algae, looking like shells and fishes and cacti," he says -- not to mention some remarkably detailed images of entire spiders and beetles, all discernible in the patterns of lepidopteran
Their presence implies that desirable pollinators also will be present at the site because many lepidopteran
larvae develop into butterflies or moths (Bawa et al.
The second and third largest percentage of prey items were orthopterans and lepidopteran
larvae, common foods of adult meadowlarks (Beal 1948) and easily found in surrounding grasslands and soybean fields throughout the breeding season.
More than five million predators have been released, resulting in significant reductions in insecticide use to control lepidopteran
larvae (NEVES et al.
In fact, previous research showed that Lepidopteran
larvae feeding on trees have a significantly higher midgut pH than larvae feeding on forbs or herbs (Berenbaum, 1980).
For several years, ARS entomologist Bob Pfannenstiel has been studying predators that feed on the eggs of lepidopteran
pests of annual crops.
There have also been a number of studies focused on avian and lepidopteran
consumer species (Holl 1996; Bajema and Lima 2001; Ingold 2002).
In cotton, we've launched WideStrike[TM] Insect Protection--a two gene Bt trait--for season-long, broadspectrum lepidopteran
In California, Landis and Menalled (1998) stuclied what type of habitat would conserve maximum community richness of parasitoids associated to lepidopteran
pests on corn, soybean, wheat, and alfalfa in the Midwestern region of the United States.
