Technical Abstract: Liriomyza sativae Blanchard, L. trifolii (Burgess) and L. huidobrensis (Blanchard) are three invasive leafminer species (Diptera: Agromyzidae) in China that have caused significant economic damage on vegetables and ornamental plants. In the current study, the repellent responses of female adults to leafminer-infested bean plants were examined with a Y-tube olfactometer. For both L. sativae and L. huidobrensis female adults, the repellent effect of the bean plants on which L. sativae had fed and oviposited was stronger than those on which L. huidobrensis had fed and oviposited. The repellent effect of the bean plants infested with L. sativae 2nd-instar larvae was stronger than those infested with L. huidobrensis 2nd-instar larvae. In a similar experiment using L. sativae and L. trifolii female adults, the repellent effect of the bean plants on which L. trifolii had fed and oviposited was stronger than those on which L. sativae had fed and oviposited. The repellent effect of the bean plants had infested with L. trifolii 2nd-instar larvae was stronger than those infested with L. sativae 2nd-instar larvae. The repellent effect of leafminer-infested bean plants on female adults was confirmed and is discussed in a context of ecological genetics of insect-plant interaction, interspecific competition and displacement of the leafmminers.
