Assessing the risk to nontarget organisms from Bt corn resistant to corn rootworms (Coleoptera: Chrysomelidae): Tier-I testing with Orius insidiosus (Heteroptera: Anthocoridae).
A 14-d continuous dietary exposure bioassay using nymphs of the insidious flower bug, Orius insidiosus (Say) (Heteroptera: Anthocoridae), was conducted to assess nontarget impacts of genetically modified corn event MON 863 expressing the Cry3Bb1 protein for management of corn rootworms, Diabrotica spp. (Coleoptera: Chrysomelidae). Nymphs of O. insidiosus were continuously fed a bee pollen diet ...
متن کاملToxicity of insecticide-bait mixtures to insecticide resistant and susceptible western corn rootworms (Coleoptera: Chrysomelidae)
Organophosphate resistant and susceptible populations of the western corn rootworm, Diabrotica virgifera virgifera LeConte. were subjected to adult feeding bioassays with different combinations of insecticide and a cucurbitacin bait. Five technical grade insecticides (methyl-parathion, carbaryl, fipronil, bifenthrin and indoxacarb) were used in combination with Invite ECt as the feeding stimula...
متن کاملBt corn pollen impacts on nontarget lepidoptera: assessment of effects in nature.
T demonstrations by Losey et al. (1) and Hansen and Obrycki (www.ent. iastate.eduyentsocynch 99yprogyabsy D81.html) that milkweed leaves dusted with heavy concentrations of Bt corn pollen are toxic to Monarch butterfly larvae (Danaus plexippus) feeding on them were consistent with the known toxicity of Bt endotoxin to Lepidoptera in general and the expression of Bt endotoxins in the pollen of t...
متن کاملAbsence of genetic divergence between western corn rootworms (Coleoptera: Chrysomelidae) resistant and susceptible to control by crop rotation.
The western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), is a major pest of corn, Zea mays L., in North America that has recently invaded Europe. A loss of ovipositional fidelity to cornfields has allowed the species to circumvent crop rotation as a means of control in part of its range in the United States. Analyses of variation at eight microsatellite loc...
متن کاملDiPel-selected Ostrinia nubilalis larvae are not resistant to transgenic corn expressing Bacillus thuringiensis Cry1Ab.
The survival of KS-SC DiPel-resistant and -susceptible European corn borer, Ostrinia nubilalis (Hübner), was evaluated on different tissues from corn, Zea mays L., hybrids, including a nontransgenic and two transgenic corn plants (events MON810 and Bt11) expressing high doses of Bacillus thuringiensis (Bt) Cry1Ab. The survival of Bt-resistant and -susceptible third instars was similar after a 5...
