Nonrandom association between host choice and fitness in bean weevil (Acanthoscelides obtectus)

摘要

AbstractThe results presented in this study indicate that host choice significantly increases one of the fitness components (preadult developmental time) in females of the bean weevil (Acanthoscelides obtectus). The host choice also affects the net replacement rate (Ro), as well as the intrinsic rate of increase (r). Using the method developed by Landeand Arnold(1983), we also measured the intensity of nonrandom association between host choice phenotypes and preadult developmental time.
