不同引诱剂与诱捕器对杨梅果蝇的诱捕效果OA

To implement effective green control measures for fruit flies in Chinese bayberry,a study was conducted from May to July 2025 in an open-air Chinese bayberry orchard in Chashan,Ouhai District,Wenzhou City,Zhejiang Province.The field trapping effects of four attractants(homemade sugar-vinegar liquid,HZ,QZ,ZJ)and five types of traps(wide-mouth bottle with black cap,wide-mouth bottle with yellow cap,mineral water bottle-type,egg-type,and cup-type)on fruit flies were compared.The results showed that the primary fruit fly species in the Chashan Chinese bayberry orchard were Drosophila melanogaster and Drosophila suzukii.In the comparison of attractants,the total trapping numbers of fruit flies ranked as follows:homemade sugar-vinegar liquid>HZ>ZJ>QZ.The homemade sugar-vinegar liquid achieved the highest total trapping numbers for both D.melanogaster and D.suzukii.In the comparison of traps,the two wide-mouth bottle-type traps captured more fruit flies than the other three types.The trapping effectiveness for D.melanogaster was wide-mouth bottle with black cap>wide-mouth bottle with yellow cap>mineral water bottle-type>egg-type>cup-type.For D.suzukii,the trapping effectiveness was wide-mouth bottle with yellow cap>wide-mouth bottle with black cap>egg-type>mineral water bottle-type>cup-type.In summary,the homemade sugar-vinegar liquid demonstrated excellent trapping performance against fruit flies and was cost-effective,making it a viable effective attractant.The wide-mouth bottle-type traps(with either black or yellow caps)exhibited superior trapping capabilities compared with other types.It was recommended that Chinese bayberry orchards in the Wenzhou region adopt the combination of"homemade sugar-vinegar liquid+wide-mouth bottle-type trap"for green control of fruit flies,with the option to adjust the trap type based on the occurrence patterns of different fruit fly species.
