| 摘 要： | 1999年作者对山西省异色瓢虫Harmoniaaxyridis (Pallas)的生物学特性进行了研究。结果表明 :该虫在山西省一年发生 4代 ,以成虫越冬。完成 1代需 2 5 12d ,其中卵期 2 5d ,幼虫期 8 6 2d ,预蛹期 1 0d ,蛹期 3 0d ,成虫产卵前期 10 0d。屋檐下角落处是其主要越冬场所之一。越冬前每日以 14∶0 0到 16∶0 0活动最为频繁。

| Abstract: | The bionomics of Harmonia axyridis(Pallas) were studied in Shanxi in 1999.The results showed that there are 4 generations a year in Shanxi province and it lives through the winter in adult. It needs 25 12 days to finish a generation, including egg stage \{2 5 days\}, larval stage 8 62 days ,pre-pupa stage 1 0 days,pupa stage 3 0 days,and pre-egg-lay stage 10 0 days.One of the major places to live through the winter is the corners of eaves. Peak activity in a day is from 14∶00 to 16∶00. |
