摘　　要：本文研究了不同密度红胸郭公虫对光臀八齿小蠹的捕食量,结果表明,单头红胸郭公虫每天可取食光臀八齿小蠹成虫2-3头,红胸郭公虫和投喂光臀八齿小蠹的密度均增加时,红胸郭公虫的捕食量有所增加,可达到4-5头。并探讨了其人工繁育中应该注意的问题,相关结果将为认识红胸郭公虫的生态功能以及后续繁育提供基础资料。This paper studied the predation quantity of T.substriatus on I.nitidus with different densities.The results showed that one T.substriatus beetle could feed on 2-3 I.nitidus adults per day, and the predation amount of I.nitidus increased with the density of T.substriatus and feeding increased, and one T.substriatus could feed on 4-5 I.nitidus adults.and some problems should be paid attention to in artificial breeding of T.substriatus.Our results will provide basic information for understanding the ecological function and subsequent breeding of T.substriatus.
