苜蓿广肩小蜂(Bruchophagus roddiGussokavsky)是紫花苜蓿的一种主要害虫,在1975年间,它导致印度旁遮普邦紫花苜蓿种子减产26～52%。鉴于这种小蜂是紫花苜蓿种子产量的一个限制因素,故极有必要对其进行有关生物学特性的研究。材料与方法1981年10月,在旁遮普邦卢迪亚纳地区在田间和3.05×2.32米~2的陶钵中,其中填装1∶2的农家肥料与土的混合物保持在荫棚中。
Bruchophagus roddi Gussokavsky, a major pest of alfalfa, caused 26 to 52% of alfalfa seed production in Punjab, India, in 1975. In view of the small bee is a limiting factor in alfalfa seed production, it is very necessary for its biological characteristics of the study. MATERIALS AND METHODS In October 1981, a 1: 2 mixture of peasant manure and earth was kept in the shade in the field and in a pot of 3.05 x 2.32 m ~ 2 in Ludhiana, Punjab.
