摘　　要：[目的]探讨性诱剂对食物诱剂引诱作用的影响。[方法]通过室内试验和田间试验研究了性诱剂对食物诱剂控制瓜实蝇的干扰作用。[结果]实验室测试结果表明,在食物诱剂中添加性诱剂对瓜实蝇的干扰较大,引诱虫口数量显著减少。田间试验也证明了这种影响明显存在并影响食物诱剂的防效。在只悬挂食物诱剂时,食物诱剂能迅速降低瓜实蝇的田间虫口密度并长期控制在较低的水平之下,防治效果显著,好瓜率在90%以上,而添加性诱剂的食物诱剂处理的好瓜率低于80%。[结论]试验结果为食物诱剂的合理使用提供了参考。[ Objective ] The aim was to explore the interference of sex pheromone on control of foocl lures for Bactrocera cucurbitae. [ Method] The interference on the controlling effect of food lures on Bactrocera cucurbitae by sex pheromone was tested in laboratory and field respective- ly. [ Result] The results of laboratory testing showed that the sex pheromone had great interference on the control of food lures for B. cucurbi- tae, the amount of B. cucurbitae attracted was declined significantly when food lures was added with sex pheromone. The further results in field experiment also showed that the sex pheromone alleviated the control effect of food lures on B. cucurbitae. The food lures had a significantly effect for reducing the pest density of B. cucurbitae and maintaining at a low level, the good fruit rate of which was above 90% , compared to that of food lures which was added with sex pheromone at a good fruit rate below 80%. [ Conclusion] The results provide reference for the rational use of food lures.
