Bt-corns are very efficient to control its main insect pest, European
corn borer (Ostrinia nubilis (Hubner)). However, European corn borer will
become resistant to the Bt-corn by alteration its population genetic
characteristics. Mating behavior relates to the genetic characteristics
that change between the parental generation and the next progeny
generation. If the parental adults mate before dispersal, it enhances the
probability of same genotypes mating events. For example, resistant
genotype mates with resistant genotype because they are physical close.
This invalidates one of the assumptions of the high dose plus refuge
strategy. My objective is to examine the female's pre- or post-mating
dispersal behavior during their first emergency night. A model will be
constructed to simulate the resistant frequency change based on the females
pre- or post-mating dispersal.
