Abstract:

    Forty-four plant volatiles were tested for their attractiveness to females of the oriental fruit fly in laboratory, and 15 out of 44 volatiles significantly attracted female flies in laboratory cage tests. Butyl butyrate, isoamyl acetate, and ethyl hexanoate were the best three in these 15 volatiles; with female trapping rates of 53.5, 69.0, and 60.0%, respectively. In the following field cage tests for these 15 volatiles, butyl butyrate, isoamyl acetate, n-butyl acetate, and ethyl hexanoate showed significant attractiveness to female flies compared to the controls. The female trapping rates were 18.2, 15.1, 9.5, and 18.2%, respectively. These 4 plant volatiles deserve investigation for possible applications.
