浙江海宁露地与大棚柑橘实蝇种群动态及不同诱捕器效能评价OA

To clarify the differences in the occurrence of Tephritidae pests between open-field and greenhouse citrus cultiva-tion in Haining,Zhejiang Province,and to evaluate the field efficacy of different fruit fly traps,field experiments were conduc-ted in a demonstration orchard with both greenhouse and open-field Hongmeiren mandarin areas using four types of fruit fly traps and one type of pheromone sticky trap.The results showed that three Tephritidae species were observed in the open-field area,with the occurrence ranking as follows:Bactrocera tau＞B.dorsalis＞B.scutellata.In the greenhouse area,two Tephritidae species were recorded,ranked as B.dorsalis＞B.tau.Overall occurrence patterns of fruit flies were consistent between the two cultivation systems.Comparison of trap performance indicated that the pheromone sticky trap had the best trapping effect,while the Beijing six-hole bucket trap and the Beijing bottle-type B.dorsalis trap performed relatively poorly.In practice,high-efficiency trapping devices such as pheromone sticky traps can be selected based on the dominant Tephritidae species in different cultivation areas.Scientific deployment of trapping devices can help achieve effective citrus Tephritidae management.
