本文为1983年八月应邀参加第十届中欧昆虫国际科学大会及第四届世界蚧虫会议的论文中文稿,英文稿将于该会论文集中刊出。论文报导世界一古老疑难属 Idiococcus 一新种的发现,由而澄清该属分类地位,建议将本属处理为锯安粉蚧 Serrolecanium 的同物异名。 This article is a Chinese version of the thesis that was invited to attend the Tenth China-EU Insect Science Conference and the Fourth World Scale Insects Conference in August 1983, and the English version will be published in the proceedings of the symposium. The paper reports on the discovery of a new species of Idiococcus, an ancient world of the world, to clarify its taxonomic status, suggesting that this genus be treated as a synonym of Serrolecanium saprophytic.
