从进口塔吉克斯坦苹果上截获重要害虫橄榄片盾蚧

Imported insects Parlatoria oleae was intercepted on apple from Tajikistan

【目的】明确橄榄片盾蚧的形态特征并编制与近似种的检索表,收集整理橄榄片盾蚧的分布范围、寄主、天敌、生物学特性、经济重要性,为该蚧虫的防控措施提供依据。【方法】通过显微特征的观察和测量进行种类鉴定,研究橄榄片盾蚧的生物学及生态学相关资料。【结果】橄榄片盾蚧雌介壳长0.77 mm左右,雌成虫体长0.55 mm左右,体紫色,臀板黄色,触角瘤小且有一个弯曲的长毛,前气门有4个盘状孔,后气门无,有3对发达的臀叶,中臀叶最大,第二臀叶和第三臀叶相似,第四臀叶呈齿状凸起,围阴腺5群。【结论】橄榄片盾蚧繁殖能力强,寄主种类多,一旦入侵到未发生区,会对当地自然生态系统造成严重的危害。加强检验检疫是防治该虫的主要措施之一,生物、化学防治是治理该虫的重要方法。

【 Aim】 To better understand how, to control Parlatoria oleae （ Colvee） invasion, its morphological characteristics were ex-amined as w,ell as its distr北ution, host, natm’al enemy, and biological and economic, importance.【 Method】 Microscope analysis w,as used to examine the morphology and measure the species characteristics.【 Result】 Female shells of P. oleae was approx 0.77 mm, and adult female approx 0.55 mm. The body of P. oleae was purple, and the pygidium was yellow. There were small duct tubercles and a cur^^e long hair. There were four lobes with the medial lobe being the largest, and the second and third lobes were similar. The fourth lobe was dentate and had 5 perivulvar pores.【 Conclusion】 With the high reproductive ability and the variety host, once P. oleae invade a new area, it can make serious damage to an ecosystem. Strengthening the inspection and quarantine is one of the main measures to prevent P. oleae, and biological and chemical measures are also important methods to control P. oleae.
