摘要
研究了我国4个地区3种生活史类型的烟蚜在烟草上的种群繁殖特征,并用Weibull模型对种群存活特征和生殖特征进行了分析。结果表明:25±1℃、14L:10D、70%±10%RH条件下,长春地区烟蚜的生殖前期和产仔高峰日分别为大于等于7d和第11d,而南京、湖南郴州和河南宜阳烟蚜的生殖前期和产仔高峰日分别为小于7d和第9d。烟蚜种群的R0、T和rm在同一地区不同体色之间以及不同地区同一体色之间均存在有差异显著性,平均寿命仅在不同地区的红色烟蚜和褐色烟蚜中有显著性差异,在黄绿色之间差异均不显著。
The reproductive characteristics of the green peach aphid, Myzus persicae (Sulzer),with three life cycles in different regions of China were studied and the survival and reproduction of the aphid was analyzed with Weibull models The results showed that the prereproduction period and the maximum reproduction date for the aphid with a holocyclic life cycle from Changchun,Jilin Province were≥7 days and the 11th day respectively For the aphid with a holocyclic and/or anholocyclic life cycle from Nanjing,Jiangsu Province and Yiyang,Henan Province,and a anholocyclic life cycle from Chengzhou,Hunan Province they were<7 days and the 9th day respectively Significant differences of r m , R 0 and T were found between the aphid populations with different body colors from the same region or from different regions with the same body color,but significant differences of mean life span were only found between red and brown forms of the aphid from different regions
