The adventive arrival of biological control agents circumvents the regulatory process by introducing exotic species to control invasive pests and is generally followed by post hoc risk evaluation. The bean plataspid, (Fabricius) (Hemiptera: Plataspidae), is an invasive pest of leguminous crops in the south-eastern United States that was eventually followed by two parasitoid wasps from its range in the eastern hemisphere, (Dodd) (Scelionidae) and Ishii (Encyrtidae). In North Central Florida, sentinel egg masses, intended to capture , instead yielded , which was previously known only from Alabama (Ademokoya et al. 2018). Two generations of were subsequently reared in the laboratory. COI sequences from the Florida population of differed by 1.3% from the Alabama population and the presence of a different haplotype suggests the possibility of a separate introduction. Laboratory parasitism rates, sex ratios, morphology, molecular diagnosis and implications for agriculture are discussed.
生物防治剂的偶然引入绕过了监管程序,通过引入外来物种来控制入侵害虫,并且通常随后会进行事后风险评估。豆平腹蝽(Megacopta cribraria (Fabricius),半翅目:平腹蝽科)是美国东南部豆科作物的一种入侵害虫,最终其东半球分布范围内的两种寄生蜂随之而来,即卵圆蝽黑卵蜂(Ooencyrtus kuvanae (Dodd),缘腹细蜂科)和库蚊恩蚜小蜂(Encarsia formosa Ishii,恩蚜小蜂科)。在佛罗里达州中北部,用于捕获卵圆蝽黑卵蜂的哨兵卵块却产出了库蚊恩蚜小蜂,此前仅在阿拉巴马州发现过该物种(阿德莫科亚等人,2018年)。随后在实验室中饲养了两代库蚊恩蚜小蜂。佛罗里达州库蚊恩蚜小蜂种群的细胞色素氧化酶亚基I(COI)序列与阿拉巴马州种群相差1.3%,且存在不同单倍型表明可能存在单独引入的情况。本文讨论了实验室寄生率、性别比例、形态学、分子诊断及其对农业的影响。
