Data from: Optimal management strategy of insecticide resistance under various insect life histories: heterogeneous timing of selection and inter-patch dispersal

Masaaki Sudo, Daisuke Takahashi, David A. Andow, Yoshito Suzuki & Takahiko Yamanaka
Although theoretical studies have shown that the mixture strategy, which uses multiple toxins simultaneously, can effectively delay the evolution of insecticide resistance, whether it is the optimal management under different insect life histories and insecticide types remains unknown. To test the robustness of the management strategy over the life histories, we developed a series of simulation models which cover almost all the diploid insect types and have the same basic structure describing pest population dynamics...

Data from: Is a larger refuge always better? Dispersal and dose in pesticide resistance evolution

Daisuke Takahashi, Takehiko Yamanaka, Masaaki Sudo & David A. Andow
The evolution of resistance against pesticides is an important problem of modern agriculture. The high-dose/refuge strategy, which divides the landscape into treated and non-treated (refuge) patches, has proven effective at delaying resistance evolution. However, theoretical understanding is still incomplete, especially for combinations of limited dispersal and partially recessive resistance. We reformulate a two-patch model based on the Comins model and derive a simple quadratic approximation to analyze the effects of limited dispersal, refuge size and...
