摘　　要：研究桔小实蝇成虫对桔、橙等9种水果的嗜好性。结果表明，桔小实蝇主要在上午9～10时取食，最嗜食的寄主是桔、橙，其次为石榴、芒果，最不嗜食的寄主是香蕉。试验进行了乐斯本等9种杀虫剂对桔小实蝇成虫的毒力测定，丁硫克百威的杀虫活性最高，其次为乐斯本，氯氰菊酯、联苯菊酯、敌百虫也具有较高的毒杀效果。The host preference of t3actrocera dorsalis to 9 kinds of fruits was studied in this paper. It showed that the most preferential host was orange and Citrus sinensis. The second was pomegranate and mango, the least preferential host was banana. The toxicity of 9 kinds of insecticides to Bactrocera dorsalis was studied. It showed that the toxicity of Carbosulfan was the highest, the second was Chlorpyrifos. The toxicity of Cypermethrin, Bifenthrin and Trichlorphon was higher than Chlorantraniliprole.
