  author={David W. Onstad and Lawrent L. Buschman},
Abstract We modified an existing model for European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), population dynamics and genetics to evaluate the effectiveness of oviposition deterrence in transgenic fields for resistance management. We simulated two types of deterrence: one type has females reducing their oviposition because of lost opportunities to lay eggs (eggs lost), and the other type has the deterred females moving to the refuge to lay eggs. Oviposition deterrence… 
Modeling Evolution of Diabrotica Virgifera Virgifera (Coleoptera: Chrysomelidae) to Transgenic Corn with Two Insecticidal Traits
A simulation model of the population dynamics and genetics of western corn rootworm was created to evaluate the use of refuges in the management of resistance to transgenic insecticidal corn, expressing one or two toxin traits, and results demonstrated that evolution is generally delayed by pyramids compared with deployment of a single-toxin corn hybrid.
How to build the non-host plant for stability in insect resistance management.
The genes for toxin and sensitivity to oviposition deterrence support each other ecologically to prevent resistance from developing to either trait, which creates a more stable insect resistance management strategy.
Application of pyramided traits against Lepidoptera in insect resistance management for Bt crops.
It is shown that products such as SmartStax and PowerCore offer compelling resistance management benefits compared with single mode of action products and allow for the option of products containing refuge seed mixtures rather than structured refuges to effectively delay resistance.


Oviposition by European Corn Borer (Lepidoptera: Crambidae) in Response to Various Transgenic Corn Events
Oviposition preference by European corn borers, Ostrinia nubilalis (Hubner), for or against transgenic corn would influence amounts of refuge required for resistance management and there is evidence that suggests cage effects influence moth oviposition more than Bt protein.
Oviposition of European Corn Borer (Lepidoptera: Pyralidae) and Impact of Natural Enemy Populations in Transgenic Versus Isogenic Corn
Although most differences between transgenic and isogenic plants were nonsignificant, all observed differences in natural enemy population parameters under the authors' conditions were in the direction opposite to that expected if transgenic plants had an adverse impact.
Modeling the Development of Resistance by Stalk-Boring Lepidoptera (Crambidae) in Areas with Irrigated Transgenic Corn
The population dynamics and population genetics of two bivoltine species of corn borers are modeled in a hypothetical region of irrigated transgenic and nontransgenic corn to examine the potential impact of behavior on resistance development.
Modeling the development of resistance by stalk-boring lepidopteran insects (Crambidae) in areas with transgenic corn and frequent insecticide use.
The population dynamics and population genetics of two bivoltine species of corn borers are simulated in a hypothetical region of irrigated transgenic and nontransgenic corn where insecticide was applied only to the nontransogenic refuge crop.
Chemically mediated ovipositional behaviors of the european corn borer,Ostrinia nubilalis (Lepidoptera: Pyralidae)
Structural modification at a single terminal functional group in these compounds affects the ovipositional behavior of European corn borer females, and Farnesol deterred oviposition.
Moth Density and Oviposition Patterns of the European Corn Borer, Ostrinia nubilalis (Lepidoptera: Pyralidae), in Alberta
Differences in moth and egg distribution are related to differences in climate and native vegetation between regions, and in arid southeastern Alberta, stands of tall, dense weeds are unavailable outside irrigated cornfields.
Dispersal of Adult European Corn Borer (Lepidoptera: Crambidae) Within and Proximal to Irrigated and Non-irrigated Corn
Generally, it was found that adult O. nubilalis dispersal may vary depending on variables such as action-site availability and agronomic practices and their interaction with the insect's life history, while mating efficiency in a late-season cornfield was not significantly different than in dense foxtail.
Distribution of European Corn Borer (Lepidoptera: Pyralidae) Egg Masses and Larvae on Sweet Corn in New York
Studies in commercial sweet corn fields in upstate New York indicated that distribution of egg masses and larvae throughout a field was essentially random with no evidence to support the hypothesis that eggs were preferentially laid near field borders where mating and resting of female adults occurred.
Fortuitous Antixenosis in Transgenic Sugarcane: Antibiosis-Expressing Cultivar Is Refractory to Ovipositing Herbivore Pests
The unintended antixenotic effects of transgenic sugarcane observed in this study are important because they highlight the validity of concerns over unanticipated consequences of releasing transgenic plants before intensive evaluation.
Economic Analysis of Transgenic Maize and Nontransgenic Refuges for Managing European Corn Borer (Lepidoptera: Pyralidae)
We simulated the population dynamics and population genetics of European corn borer, Ostrinia nubilalis (Hubner), and damage to maize in a hypothetical region containing transgenic and nontransgenic
