| 摘 要： | 2010-2011年对不同播种期条件下麦蚜发生量及七星瓢虫种群动态进行了研究。结果表明,适期播种田七星瓢虫迁入早,经控制蚜虫基数小,蚜量增长缓慢;晚播田七星瓢虫迁入晚,蚜虫基数大,蚜量增长迅速。2011年七星瓢虫在当地麦田大规模发生,麦蚜在扬花期已被七星瓢虫有效控制。 |

| Abstract: | In 2010 and 2011, the experiments were carried out on the relationships between the quantity of aphids and the population of Coccinella septempunctata in different sowing times. C. septempunctata immigrated earlier when the wheat sowing time was normal, and the population of the aphids was small, and the growth was slow. However, C. septempunctata immigrated later when the wheat sowing time was delayed, and the population of the aphids was big, and the growth was fast. C. septempunctata outbroke in the wheat fields in 2011, and the aphids had been controlled at flowering stage. |
