几种新型食诱剂对柑橘小实蝇引诱效果评价OA

To screen efficient food attractants for field control of Bactrocera dorsalis,this study compared the trapping ef-fects of several novel commercial products from July 1 to December 12,2023.The results indicated that during the 155-day test period,the bisexual fruit fly attractant trapped a total of 7 550 adults,consisting of 5 491 females with a female ratio of 72.7%.It captured the maximum number of females that achieved the optimal trapping effect.Yingbijue concentrated bait ranked second,trapping 3 413 adults,including 2 612 females.Its female proportion reached 76.5%,the highest value in all groups,while the total trapped quantity was relatively low.Protein bait trapped 1 274 adults,with 828 females and a female ratio of 65%,presenting ordinary trapping performance.The Liechong fruit fly attractant trapped 13 196 adults,yet only 479 were females,accounting for 3.6%.It hardly trapped female flies and mainly attracted males.The 1%thiamethoxam bait trapped 10 469 adults with only 16 females,occupying 0.2%,showing basically no trapping effect on females.The methyl eugenol sex attractant trapped 34 380 adults with zero females,and it only worked on male flies.Female adults of Bactrocera dorsalis mainly cause damage to citrus fruits in fields,and female population quantity determines the damage severity.Con-sequently,the bisexual fruit fly attractant and Yingbijue concentrated bait exert superior control efficacy against damage caused by Bactrocera dorsalis compared with other tested food attractants.
