引诱剂对杨梅果蝇的控害效能OA

Fruit fly infestations severely constrain the sustainable development of Myrica rubra industry.To identify environmentally friendly control technologies,this study conducted a systematic evaluation of the trapping efficacy of attractants on different phenological stages of Myrica rubra fruit flies and their field control efficacy through a three-year continuous field trial.The results showed that the test attractant exhibited stable trapping activity at all experimental sites.And the overall mean trapping numbers during the initial,peak,and late occurrence stages were 176.2,313.1,and 63.4 individuals per trap,respectively.Fruit infestation rate surveys revealed that the overall mean infestation rate was significantly(p<0.05)lower than that in control plots.The mean control efficacy during the early,peak,and late harvest stages were 89.82％,93.06％and 81.54％,respectively,with an overall mean efficacy of 85.59％across the entire harvest period.Control efficacy exceeded 84.00％at all four sites,with no significant differences among locations,indicating good ecological adaptability of the attractant under diverse geographical and climatic conditions.In conclusion,the tested attractant exhibited excellent trapping activity against Myrica rubra fruit flies and demonstrated stable field control efficacy,making it a viable green control technology for Myrica rubra fruit flies which can be widely adopted in production practices.
