摘要: 苹果黄色叶螨是近年四川省三州苹果产区发生的一种害螨。该螨在雅安一年发生8~9代。以部分第8代和第9代雌成螨越冬。越冬雌成螨于次年3月上、中旬开始活动,以两性生殖及孤雌生殖繁殖后代。全年中越冬代历期长约5个多月,其余各代约1.5个月。各虫态历期因世代不同而异。各代雌螨寿命及产卵量,以越冬代及春、秋代寿命长,产卵量高。

Abstract: Eotetranychus sp. was an important injurious mite of Apple in the three autonomous districts of Sichuan Province in recent years. There were 8-9 generations descending for the mite per year in Yaan. Female adults of the part of the 8th generation and the 9th generation over wintered through 5 months and acted in mid-March next year. They bred in sexuality and parthenomixis. There was 1.5 months lifetime per generation except the over wintering one. The lifetime and the quantity of laying eggs were different among the various generations. The over wintering generation and the Spring and autumn generations might live longer and lay much more eggs.
