小麦吸浆虫近年来在北京市通州区发生面积不断扩大,为掌握小麦吸浆虫发生情况,找出适宜通州地区的防治技术,对其发生规律进行了调查。其活动幼虫在耕作层中的变动,有明显的季节性,春季0~7 cm土层中活动幼虫比率与5 cm土层平均地温基本呈正相关。发生程度和土壤质地、灌溉方式以及小麦品种都有一定程度的关系。
In recent years, wheat midge in Tongzhou District of Beijing occurred in an area of growing, in order to master the occurrence of Midazolam, to find out appropriate prevention and control technology in Tongzhou area, the occurrence of the law were investigated. The change of active larvae in tillage layer was obviously seasonal. The ratio of active larvae in 0 ~ 7 cm soil layer in spring was positively correlated with the average ground temperature in 5 cm soil layer. Occurrence and soil texture, irrigation methods and wheat varieties have a certain degree of relationship.
