叶螨的重要天敌——深点食螨瓢虫的研究进展

Advances in research on Stethorus punctillum, an important predator of the spider mite

叶螨个体小、分布广、繁殖力高、扩散速度快,易对化学杀虫剂产生抗性,在农业生产中为害严重且防治困难,是世界性的重要害虫。在果园等农业生态系统中,深点食螨瓢虫Stethorus punctillum Weise是食螨瓢虫和叶螨天敌中的优势种,对叶螨种群的生物防治起着极其重要的作用。本文综述了深点食螨瓢虫的研究进展,主要包括形态特征、地理分布、发生规律、生态学、行为学、人工饲养等方面的研究,阐明了深点食螨瓢虫作为叶螨天敌的重要作用,以期为充分利用该瓢虫生物防治叶螨提供科学参考。

The spider mite an important global pest due to its small size, wide distribution, high reproductive capacity, rapid dispersal and resistance to insecticides. Stethorus punctillum Weise is a natural predator of spider mites that plays an important role in the biological control of these pests in orchards and other agricultural ecosystems. We summarize progress in research on S. punctillum, including its morphological characteristics, geographical distribution, occurrence, ecology, ethology, feeding and related factors affecting predation. This review documents the important role of S. punctillum in controlling spider mites and promotes the further utilization of this species as a biological control for these pests.
