摘要
烟粉虱[Bemisia tabaci(Gennadius)]是小黑瓢虫[Delphastus catalinae(Horn)]的捕食猎物之一。提供6种寄主植物进行烟粉虱的选择试验,发现寄主植物对烟粉虱生长发育和存活的影响不明显,主要影响其成虫生殖力和种群增长。通过比较烟粉虱的种群增长指数(I),发现花椰菜、一品红、豇豆和烟草这4种寄主植物比较适合用于人工大量繁育烟粉虱,其中花椰菜的饲养效果最佳,最有利于烟粉虱种群的快速增长。
Bemisia tabaci （Gennadius） is one of the prey of Delphastus catalinae （Horn）. Preference experiments were made respectively provided with six host plants to B. tabaci. The results showed that host plants mainly affected the propagation and population growth of B. tabaci significantly. Comparing the population growth index （I） of B. tabaci, we found that cauliflower, poinsettia, cowpea and tobacco were fitted to rear B. tabaci in a large number, and cauliflower was the best host plant for B. tabaci, with the maximal population growth index （I） of B. tabaci developed on it.
