摘要
研究了广东主要百合种类对桃蚜生长、发育和繁殖的影响。结果表明,不同百合种类因所含的营养成分和化学物质不同对桃蚜数量及生长发育产生不同影响。以作用因子组建实验种群生命表,龙牙百合上的桃蚜种群趋势指数最大,为35.765,最有利于种群的增长;其次为宜兴百合、麝香百合,其种群趋势指数分别为28.512和14.533;兰州百合上的种群趋势指数最小,为4.166。
The effects of main lily varieties in Guangdong on the development and reproduction of Myzus persicae were studied.Research indicated that bio-chemical factors such as nutrition and chemicals in lily,and physical and morphological characters of leaves affect development and population dynamics of M.persicae.The index of population trend (I) of M.persicae on Lilium henryi was highest,with the value of 35.765,followed by L.speciosum and L.longiflorum,with the value of 28.512 and 14.533.The index of population trend I on L.tigrinum was lowest,with the value of only 4.166.
