Dispersal of newly eclosed European corn borer adults (Lepidoptera: Crambidae) from corn into small-grain aggregation plots.
Genetically modified, insecticidal Bacillus thuringiensis (Bt) corn, Zea mays L., hybrids are used throughout the Corn Belt for European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), control. To slow development of Bt corn resistance, the Environmental Protection Agency requires growers to plant a refuge. Determining the appropriate distance between a refuge and Bt corn, and...
متن کاملEffect of age and mating status on adult European corn borer (Lepidoptera: Crambidae) dispersal from small-grain aggregation plots.
The European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), is often controlled with genetically modified corn, Zea mays L., hybrids (Bacillus thuringiensis [Bt] corn) in the United States. If Bt-resistant insects are detected in the field, mitigation-remediation tactics must be implemented to sustain the efficacy of insecticidal, transgenic corn. Mass releasing laboratory-re...
متن کاملAggregation and Dispersal Behavior of Marked and Released European Corn Borer (Lepidoptera: Crambidae) Adults
To observe the aggregation and dispersal behavior of adult European corn borer, Ostrinia nubilalis (Hu ̈ bner), males in search of mates, two populations were marked, each with a different dye. One population was continuously reared in the laboratory (.5 yr) and the other was collected annually from the Þeld. From 1986 to 1988, marked adults were released in two release sets per year, with three...
متن کاملLate-instar European corn borer (Lepidoptera: Crambidae) tunneling and survival in transgenic corn hybrids.
Field studies were conducted in 1996 and 1997 to determine injury by and survival of late-instar European corn borer, Ostrinia nubilalis (Hübner), on genetically altered Bacillus thuringiensis Berliner corn, Zea mays L. Cry1Ab events 176, Bt11, MON810, and MON802; Cry1Ac event DBT418; and Cry9C event CBH351 were evaluated. Plants of each corn hybrid were manually infested with two third-, fourt...
متن کاملOviposition by European Corn Borer (Lepidoptera: Crambidae) in Response to Various Transgenic Corn Events
Oviposition preference by European corn borers, Ostrinia nubilalis (Hübner), for or against transgenic corn would influence amounts of refuge required for resistance management. The objective of this research was to determine if various Bacillus thuringiensis (Bt) corn transgenic events influence O. nubilalis oviposition. All commercially available events (currently 5) were evaluated, plus 1 ex...
