摘要
近年来,双斑长跗萤叶甲数量逐年上升,其分布广泛,寄主多样,危害严重,成为玉米、大豆等作物上的重要害虫.笔者于2022年7-9月在吉林公主岭田间采集双斑长跗萤叶甲成虫时,在其体内发现了一种寄生蜂.通过形态学及分子生物学鉴定为冈田长柄茧蜂Streblocera(Eutanycerus)okadai Watanabe(茧蜂科Braconidae长柄茧蜂属Streblocera亮角茧蜂亚属Eutanycerus),基于COI基因的分子进化树结果显示与长柄茧蜂属寄生蜂聚为一类.截至目前,国内外未有双斑长跗萤叶甲寄生性天敌报道.本研究填补了双斑长跗萤叶甲寄生蜂生防资源的空白,也为该害虫的生物防治提供了新策略.
Abstract
In recent years,Monolepta hieroglyphica has increased in population size year after year,becoming an essential pest on corn,soybeans,and other crops due to its wide distribution,diverse hosts,and severe damage.From July to September in 2022,a parasitic wasp parasitizing M.hieroglyphica adults in the fields of Gongzhuling,Jilin province was collected.It was identified by morphology and molecular method as Streblocera(Eutanycerus)okadai Watanabe of Braconidae.Based on CO Igenes,the wasp species was phylogenetically clustered with the genus Streblocera.This is the first report of parasitic enemies of M.hieroglyphica,which may provide a new strategy for the biological control of this pest.
