Behavioral response of Bactrocera dorsalis to five kinds of odor volatile of mango

Abstract：In order to explore behavioral responses of Bactrocera dorsalis (Hendel) to host odor volatiles，the test of behavior of B. dorsalis to five kinds of odor volatiles of mango ( ethyl acetate，α-pinene，terpinolene， 3-carene and caryophyllene) and the mixture of these five volatiles was conducted with Y-tube olfactometer in laboratory. The results showed that female and male adults of the fruit fly had no significantly different behavior response to five kinds of odor volatiles and their mixture. The results also revealed that adults of B. dorsalis preferred to ethyl acetate，but refused terpinolene significantly. Moreover，adults showed no distinct directional behavior to α-pinene，3-carene，caryophyllene and the mixture of five volatiles. All results indicated that adults of fruit fly showed different behavior responses to odor volatiles of mango，which may provide useful information of studying new methods to control adults of fruit fly.
