摘  要:
本文报道了5种食螨瓢虫在四川的分布。其中,束管食螨瓢虫、深点食螨瓢虫、云南食螨瓢虫为优势种。食螨瓢虫以成虫在树上卷叶及地表枯枝落叶内越冬,随着不同寄主植物上叶螨高峰期不同,食螨瓢虫存在栖息作物转移现象。在桔园内,食螨瓢虫与桔全爪螨的空间生态位重叠大,而时间生态位重叠小。

摘  要:
Five species of Stethorus in Sichuan province were found and their distribution was investigated. The dominant ones are Stethorus chengi Sasaji, S. punctillum Weise and S. yunnanensis Pang et Mao. They over- winter mainly in adult stage in curved citrus leaves and in litters on the ground. The Stethorus spp. changed their habitat plants in a year or changed the pick time of their prey on different plants. In citrus orchard, the spatial ecological niches of Stethorus spp. greatly overlap that of their prey (Panonychus citri Mcgregor), the overlap of time niches, however, was much smaller.
