摘要
对紫花苜蓿种子的重要害虫苜蓿籽蜂的生物学特性进行了研究。结果表明,苜蓿籽蜂在新疆呼图壁地区1年发生3代,主要以3龄幼虫在苜蓿种子内越冬。越冬幼虫于次年4月下旬开始化蛹,5月上旬开始羽化;7月上旬出现第1代成虫,7月下旬出现第2代成虫。成虫羽化多集中在白天10:00～14:00,平均性比约为1.34∶1。不同营养条件对成虫寿命及产卵量的影响不同,其中以5%蜂蜜水饲养成虫寿命最长、产卵量最高。
This study was conducted to analyze biological characteristics of Bruchophagus roddi （Gussak-ovsky） of the main pests of alfalfa seeds. The result demonstrated that there were three generations in a year at H utubi area in Xinjiang, and the third instar larvae overwintered in alfalfa seeds.Overwintered larva starts pupation in the next April and emergenced in in the first ten-day period of May.The adult emergenced in the first ten-day of July,while the second generation adult emergenced day of July.Adults were actively flying between 10：00-14：00,sex ratio was about 1.34 ： 1. ferent effects of different nutritional conditions on adult longevity and fecundity, of which t who were fed on honey water was the longest, their fecundity was the highest. first generation in the third ten-There were dif-he life of adults
