摘　　要：为了寻找华山松木蠹象(Pissodes punctatusLangor et Zhang)环境友好的防治方法,研究了亚油酸、庚二酸、辛二酸、壬二酸、壬酸的酒精溶液、乙酸乙酯溶液和水溶液对华山松木蠹象成虫的拒食作用,采用了完全拒食虫率与相对拒食率来评价有机酸的拒食效果。结果表明,壬酸的3种溶液都具有很好的拒食作用,特别是水溶液其完全拒食虫率和选择性相对拒食率都高达100%。其它4种酸的不同溶液、不同试验方法的结果不尽相同。壬二酸的相对拒食率有的较高,有的表现为促进取食的作用,其乙酸乙酯溶液的完全拒食虫率高达100%。亚油酸、庚二酸、辛二酸主要表现为促进取食的作用。An experiment was conducted to study the antifeeding effects of ethanol, ethyl acetate and water solutions of linoleic acid, pimelic acid, suberic acid, azelaic acid, and n-nonanoic acid against imago of Pissodes punctatus. Absolute antifeeding rate and relative antifeeding rate were used to appraise the antifeeding effects of organic acids. For n-nonanoic acid, its three kinds of solutions all had good antifeeding activities, especially its water solution, of which the absolute antifecding rate and relative antifeeding rate both reached 100 percent. Different types of solutions or different experiment methods of other organic acids exhibited various antifeeding effects. Azelaic acid showed a higher relative antifeeding rate or a promotion effect on eating, and the absolute antifeeding rate of its ethyl acetate solution could reach 100 percent. While the linoleic acid, pimelic acid, and suberic acid mostly displayed promotion effects on eating.
