麦茎谷蛾（OCHSeHemeASP），是江苏淮北麦区迅速发展蔓延的大麦新害虫，已经成为六棱大麦增产的障碍，搞清麦茎谷蛾幼虫的田间分布规律，对于进一步深入研究麦茎谷蛾的发生危害特点、完善测报防治技术，具有一定的意义。1993年以来，我们对麦茎谷蛾幼虫的田间分布型及其抽样技
Wheat stem moth (OCHSeHemeASP), is a new pest of barley grown and spread rapidly in Huaibei, Jiangsu Province. It has become an obstacle to increase yield of hexagonal barley and clarify the field distribution rules of wheat stem moth larvae. The occurrence of hazards, improve forecasting prevention and control technology, has a certain significance. Since 1993, our field distribution patterns and sampling techniques of wheat stem moth larvae
