【摘要】 为了明确烟蚜Myzus persicae(Sulzer)生长的最适寄主,研究了烟蚜在烟草、油菜和萝卜上的生长发育历期、存活率和繁殖率等.结果表明,依据室内种群生命表试验,烟蚜在3种寄主上的发育历期、日平均最高产蚜量有显著差异.利用生命表参数综合评价,试蚜在3种寄主上内禀增长率(rm)和净生殖率(R0)分别为0.308,0.263,0.243和73.433,68.582,67.796,说明烟蚜最喜食烟草,其次是油菜和萝卜.更多还原

【Abstract】 In order to define the optimal host plants Myzus persicae(Sulzer),the developmental duration,the population survival rate and reproductive rate Myzus persicae(Sulzer) on tobacco,rape and radish were studied.The results show that there were significant differences in development duration and average daily production quantity of Myzus persicae(Sulzer) on different host plants.With the comprehensive evaluation of the life table parameters,the innate capacity for increase(rm) of Myzus persicae(Sulzer) on different host plants was 0.308,0.263 and 0.243 respectively,and the net reproductive rate(R0) was 73.433,68.582 and 67.796,which indicate that Myzus persicae(Sulzer) like eating tobacco most,with rape and radish coming next.更多还原
