摘　　要：对桔小实蝇进行虫果热处理试验和田间引诱试验,结果表明:卵的耐热力最弱1,龄、2龄幼虫较强,老熟幼虫的耐热力最强;60℃,120 min或45℃,300 min干热处理虫果杀虫效果达到100%,适用于口岸发现桔小实蝇后的检疫处理。筛选出诱捕效果最好的5种药剂组合,其中甲基丁香酚+多杀霉素组合在成本上具有优势,而水解蛋白+多杀霉素组合、水解蛋白等药剂组合防治效果更显著,适用于新传入种群的消除。The thermal treatment toward the fruits infected by Bactrocera dorsalis and the trapping technique for this pest conducted in the orchards was experimented.The results showed that the eggs were most sensitive to the thermal treatment,followed by the first and the second instars,while the mature worms were most resistant to the thermal treatment.The pest killing effect was the best when the infested fruits were treated at 60 ℃ for 120 min or at 45 ℃ for 300 min,the mortality rate of all stage instars of B.dorsalis could reach 100 %.The thermal treatment was suitable to be applied for quarantine treatment to the infested fruits found at the ports.Five combinations of pesticide with the best attractive trapping effect were selected,among which methyl eugenol mixed with spinosad cost the least.Whereas the protein hydrolysate mixed with spinosad,or protein hydrolysate had better control effect,which was suitable for eradication of newly invaded groups.
