柑桔小实蝇Dacus(bactrocera)dorsalis(Hendel)在云南景谷1年发生5代,以老熟幼虫和蛹在土壤中越冬或越夏。2月中至8月中旬,成虫产卵于芒果果实内,致使芒果腐烂。室内用40%氧化乐果、50%杀螟松和80%的敌敌畏1000、1500倍液,对成虫的毒杀率达100%,幼虫达88.73%,蛹为10.0%。大田防治用1000倍液,同时用性信息素进行诱杀,保果效果达95.74%。
Citrus fruit fly Dacus (bactrocera) dorsalis (Hendel) occurred in Yunnan Valley for 5 years to 1 year, with mature larvae and pupae in the soil overwinter or summer. From mid-February to mid-August, adults lay eggs in the mango fruit, causing the mango to decay. Indoor with 40% omethoate, 50% fenitrothion and 80% of dichlorvos 1000,1500 times, adult poisoning rate of 100%, larvae reached 88.73%, pupa was 10.0%. Field control with 1000 times the liquid, at the same time sex pheromone trapping, fruit protection effect of 95.74%.
