Table 3: Logistic regression analysis of sources of variation in mating preferences of male and female B. treatae assayed from no-choice mating trials. This analysis evaluates the influence of the male and female B. treatae source population and the presence versus the absence of the host plant during mating trials on the probability of mating. Foliage = present or absent; male and female host = host plant species from which each sex was collected (Q. geminata or Q. virginiana).
