摘要: When microbial agents are used as pest-control agents, resistance in the host may be selected for. If occurs there potentially fitness costs due to trade-offs between and other life-history traits. Genotypic with a virus lepidopteran examined by micro-evolutionary selection experiment. Six populations of Indian meal moth, Plodia interpunctella, were established, three which supported granulosis infection (selected insects) while remaining acted virus-free controls. After period 2 years, bioassays showed that moths 1.96-fold more resistant (LD 50 s) than those derived from control
