摘　　要：枣球蜡蚧是满洲里榆树上的主要害虫,以若虫和雌性成虫严重危害榆树。为了掌握该虫发生规律,对其展开了调查研究。研究结果,满洲里7个地区平均虫口密度为3.57个/10 cm,平均有虫株率为57.86%。危害最严重和最轻的地区分别是203国道和机械化林场,危害指数分别为30.2和0。不同地区枣球蜡蚧有虫株率图显示,由远方中学到机械化林场这7个地区枣球蜡蚧发生规律可能与榆树种植区地理方位有关,本次调查研究为今后防治杏球坚蚧提供有效的数据依据。Eulecanium gigantea is the main pest for elms in Manzhouli. It is mainly caused by nymphs and female adults. The investigation was carried out in order to understand the outbreak regularity of this insect. The results showed that the average population density of 7 areas in Manzhouli was 3.57/10 cm, and the average percentage of insect strains was 57.86 %. The most serious and least hazardous areas were respectively the national highway 203 and the mechanized forest farm, and the hazard index was 30.2 and 0 respectively. The plant strain rate of eulecanium gigantea in different regions showed that the occurrence regularity in 7 regions from Yuanfang Middle School to the mechanized forest farm may be related to the geographical location of the elm planting region. This investigation provided effective data basis for the prevention and treatment of Sphaerolecanium prunastri in future.
