| The Chinese citrus fly, Bactrocera minax (Enderlein) has become the most serious hazards and destructive pest in the major citrus producing areas. In order to provide scientific basis and theoretical guidance for the formulation of attractant and field work. In this article, it measured the EAG relative value of 10 substances in different concentrations, 7 kinds of common formulation and 5 kinds of improved formulation, and evaluated the attractive effect of 9 kinds of formulations in 2010 and 2011 in 5 citrus orchards of Sichuan and Chongqing. The main results were as follows. The EAG responses of male and female adult was increased faster with increasing concentration of acetic acid, hydrolyzed protein, and female increased faster with increasing concentration of ethanol. But male and female adult with brown sugar, sweet orange juice, orange essential oil, ethyl acetate, orange peel powder, citric acid, honey concentration increase did not change significantly. In the formulation, the EAG relative value and the field attractive effect of 20% hydrolyzed protein were significantly higher than other formulation. The attractive effect of improved sugar-acetic acid-ethanol with 5% hydrolyzed protein or 0.2% ethyl acetate is increased. |
