| 摘 要： | 胡麻茎蜂对胡麻的正常生长为害严重,因此开展了胡麻茎蜂种群动态研究。结果表明,胡麻茎蜂在当地每年发生1~2代,胡麻茎蜂成虫分别于6月上中旬、7月末至8月上旬在田间为害达到高峰,胡麻茎蜂幼虫分别于6月中旬和7月中旬在田间为害达到高峰。根据胡麻茎蜂发生特点和规律,5月中旬末至5月下旬初,在冬麦田药剂防治成虫,可最大程度地控制虫口基数。

| Abstract: | Cephus sp. makes serious damage to the normal growth of flax, so a study was made on the population dynamics of Cephus sp. on oil flax. The result showed that in the local area Cephus sp. reproduced 1- 2 generations each year. The damage made by the adult of Cephus sp. on oil flax on the farmland reached the peaks during the early and middle June, late July and Early August. The damage made by the larva of Cephus sp. on oil flax on the farmland reached the peaks during the middle June and middle July. Based on the characteristics and the law of occurrence of Cephus sp. on oil flax, the population base could he controlled to the greatest extent if the pesticide be applied on the winter wheat farmland to control the adult at the end of middle May and the beginning of late May. |
