摘要： Insect pollination is an important process in the natural ecosystem and plays a vital role in crop reproduction. The bumblebee, Bombus terrestris (L.), is a widely used pollinator for crops, especially tomato. The efficiency of bee pollination is related to many factors, including biotic factors such as bee species, nutrition plants, and herbivores. Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) is one of the most common and serious pests of tomato plants. However, whether B. tabaci affects the pollination behaviour of B. terrestris on tomato, and how plant-herbivore-pollinator interactions are unclear. In this study, we found that B. terrestris preferred B. tabaci-damaged plants. Furthermore, plant volatiles of tomato plants damaged by B. tabaci were detected and analysed. Electroantennogram (EAG) and the Y-tube bioassay were used for olfactory responses of B. terrestris to plant volatiles. Interestingly, methyl hexanoate and eugenol induced by B. tabaci in tomato plants were found to significantly attract B. terrestris. Therefore, Bemisia tabaci influenced B. terrestris preference through volatiles. The plant volatile-mediated interaction between B. tabaci and B. terrestris could enrich our understanding of the interaction between herbivores and pollinators. In addition, methyl hexanoate and eugenol could be applied for synergist of pollination.
