We confirmed the occurrence of interspecific hybridization between Liriomyza sativae and L trifolii on kidney bean (Phaseolus vulgaris L.) at 25°C under a 15L-9D photoperiod regime. Among 48 replications of L sativae females and L trifolii males tested, females of 19 replications (39.6%) oviposited, but no eggs hatched. In contrast, among 115 replications of L trifolii females and L. salivae males tested, females of 47 replications (40.9%) oviposited and progeny from 10 replications (8.7%) developed to adult eclosion. The hybrid offspring were obtained only when several L. trifolii females and several L sativae males were placed together. The hatchability, pupation rate, and adult emergence rate of hybrid flies were 14.9%, 94.9%, and 61.8%, respectively. All the hybrid adults were female (n=127). When these females were backcrossed with males of either species, none oviposited. The mean adult longevity of a hybrid female was 19.2d.
