Abstract:
... Chemical control of insect pests remains vital to agricultural productivity, but limited mechanistic understanding of the interactions between crop, pest and chemical control agent have restricted our capacity to respond to challenges such as the emergence of resistance and demands for tighter environmental regulation. Formulating effective control strategies that integrate chemical and non-chemic ...

Abstract:
... Cropping systems that include forage legumes and small grains in addition to corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] can achieve similar or higher crop productivity and economic return than simpler corn–soybean rotations. We hypothesized that this rotation effect occurs regardless of the crop genotype planted and the herbicide and cultivation regime selected for weed management. To ...

Abstract:
... Transgenic Bt (Bacillus thuringiensis) corn (Zea mays L.) hybrids with resistance to corn rootworm (CRW; Diabrotica spp.) or European corn borer [ECB; Ostrinia nubilalis (Hübner)] can have greater tolerance to water and nutrient stress, and thus may have higher optimum plant densities. Experiments were conducted following soybean [Glycine max (L.) Merr.] over nine site-years in Illinois to determi ...

Two field experiments were conducted to assess the agronomic and yield performance of transgenic rootworm trait, Bacillus thuringiensis (Bt) Cry3Bb, seed-coating treatment, and a soil-applied insecticide under natural corn rootworm infestation. Experiment 1 comp ...

Abstract:
... Larval corn rootworms (Coleoptera: Chrysomelidae) are soil-dwelling insect pests that damage maize (Zea mays L.) by consuming root tissues, thus lowering grain yield. Little is known about interactions between rootworms and soil bacteria, including potential impacts of maize rhizobacteria, such as entomopathogenic Serratia spp., on subterranean rootworm pests. We used selective growth medium (capr ...

In the first trial, 2 diets, 1 formulated with MON 863 and 1 with conventional corn, were fed to laying hens (12 replicate cages with 4 hens/cage per treatment) for 8 wk. Daily feed intake (FI), egg production (EP), and BW were measured. Prestudy fecal samples, wk 4 a ...

Abstract:
... The corn rootworm (CRW; Diabrotica spp.) is one of the most serious pests of corn in the USA. Chemical insecticides and crop rotation have been the only two options available to growers for managing CRW. Unfortunately, both of these tactics can be ineffective as a result of either resistance or behavioral modifications. In this paper, we describe transgenic maize (Zea mays L.) hybrids that control ...
