卵巢解剖在褐飞虱Nilaparvata lugens(Stl)的迁飞研究和预测预报中起着重要的作用,但由于卵巢解剖是一项精细化的技术,在实际的病虫测报工作中,解剖技巧和分级标准难以被基层植保工作者掌握。为了使卵巢解剖技术在病虫测报中发挥其应有的作用,本研究在前人工作的基础上,根据我国病虫测报工作中卵巢分级的实践性及基层站点的可操作性,通过对不同羽化时长的褐飞虱长翅型雌虫进行卵巢解剖,详细描述了褐飞虱卵巢发育的形态变化过程,进一步完善了褐飞虱的分级标准,解决了之前的分级难点,且操作简便易行,分级特征明确,可广泛适用于我国各基层植保部门的常规监测和预报工作。 Ovary anatomy plays an important role in the migration and prediction of Nilaparvata lugens (Stl), but because ovarian dissection is a delicate technique, in the actual pest detection work, the anatomic skills and grading The standard is difficult to grasp by grassroots plant protection workers. In order to make ovarian anatomical technology play its due role in pest forecasting, based on the previous work, according to the practicality of ovarian grading and the operability of grass-roots site in pest forecasting in our country, The oviposition period of the brown feather-feeding long-winged females of oviposition period was described in detail. The morphological changes of the ovary of the brown planthopper were described in detail, and the grading standards of brown planthopper were further improved. The previous grading difficulties were solved and the operation was simple and easy. Widely used in China’s grassroots plant protection departments of the routine monitoring and forecasting.
