Abstract:

[Objectives]  To investigate the preferences of Neoseiulus bicaudus Wainstein for different host plants and their volatiles. [Methods]  The relative preferences of N. bicaudus for volatiles of five host plants (bean, cotton, tomato, eggplant, cucumber) subject to different treatments (healthy plants, mechanically damaged plants, infested with spider mites and infested with other mites) were investigated in a Y-tube olfactometer. [Results]  Preferences of Neoseiulus bicaudus for volatiles of the five host plants can be ranked as follows: infested with spider mites > infested with other mites > mechanically damaged leaves > healthy leaves > clean air. Volatiles from mite-infested bean and cotton plants were significantly more attractive than those of eggplant, tomato and cucumber. [Conclusion]  The volatiles of different host plants play an important role in the process of host species identification and the selection of individual host plants.
