大豆根绒粉蚧(Eriococcus sp.)属同翅目,粉蚧科,是2000年以来黑龙江省北安市新发生的害虫。近年来,随着气候环境、耕作制度、种植模式的改变,该虫发生面积逐年加大,为害越来越重,对本市大豆生产造成严重威胁。为此,我们于2004～2007年在本市通过田间调查和室内饲养观察,对该虫的生活习性、发生规律和防治技术进行了初步研究。 Eriococcus sp. Belongs to Homoptera and Festifera, and is a new pest in Bei’an, Heilongjiang Province since 2000. In recent years, with the change of climatic environment, cultivation system and planting pattern, the pest occurrence area increases year by year, causing more and more damage, which poses a serious threat to soybean production in this city. To this end, we conducted a preliminary study on the living habits, occurrence rules and control techniques of this pest in our city from 2004 to 2007 through field surveys and indoor rearing observations.
