| 摘 要： | 杂交试验结果表明,北京地区寄生于马铃薯廿八星瓢虫幼虫和蛹的姬小蜂,与原产印度的瓢虫姬小蜂不存在生殖上的隔离。采用聚丙烯酰胺凝胶电泳方法对上述来源不同姬小蜂的同工酶作比较:两姬小蜂的乳酸脱氨酶(LDH)、苹果酸脱氢酶(MDH)和醇脱氢酶(ADH)同工酶谱均无差异,酯酶同工酶酶谱基本一致,表明两姬小蜂在上述同工酶的基因控制上,具有同一物种的遗传特征。根据杂交试验和同工酶酶谱分析结果,可以推断北京地区的姬小蜂种名应为瓢虫姬小蜂(Pediobius foveolatus(Crawford)。

| Abstract: | Pediobius sp. was obtained from the larvae and pupae of potato 28-spotted beetle, H. vigintioctomaculta. an important potato pest in Beijing. In a cross-mating test, this Pediobius species was found to have no reproductive isolation with P. feveolatus introduced from India. Electroreis studies using polyacrylamid gel showed that the esterase, lactate dehydrogenase, malic dehydrogenase and alcohol dehydrogenase of the two Pediobius populations were monomorphic, with only one different zone existed in the esterase. It is thus believed that the Beijing Pediobius sp. is the same species as P. feveolatus from India. |
