介绍了大豆根绒粉蚧形态特征及防治技术。大豆根绒粉蚧害虫是黑龙江省中北部部分市县新发生的一种大豆虫害,以成虫、若虫刺吸大豆茎部及叶片,严重影响豆株的生长发育。防治措施一是减少大豆根绒粉蚧在田间的越冬基数,二是以内吸型药剂为主,在害虫尚未形成蜡质保护层的一龄若虫期及时进行药剂防治。
The configuration characteristics and management tech- nique of Ericoccus sp. were introduced in this paper. Ericoccus sp. is a new soybean pest in parts of central and orthem cities and coun- ties in Heilongjiang Province. Its adult and nymphae absorbs the stem and leaves of soybean plan, which could affect seriously the growth and development of soybean plant. One of the prevention measurements is to decrease the Ericoccus sp. living insect pests over the winter, and the other is spray pesticide before forming its wax protection layer at its firstage nymphae stage.
