Factors Affecting the Occurrence of Second Copulation by Mediterranean Fruit Fly Females (Diptera: Tephritidae)

Abstract

Logistic regression was used to construct two models to predict the occurrence of second copulations by Mediterranean fruit fly females in sequential copulations with fertile males or with irradiated and non-irradiated males. Male genotype and duration of the first copulation were significant variables in determining the occurrence of a second copulation by individual females. Male age and irradiated male mating order were additional significant variables in sequential copulations with irradiated and non-irradiated males.
