摘　　要：为探讨西花蓟马Frankliniella occidentalis在不同辣椒品种上的发生及为害规律,以5个辣椒品种作为试验材料,组建西花蓟马种群生命表。结果表明,从西花蓟马各个虫态的发育历期来看,‘杭椒五号’和‘太空辣’比较适合蓟马生长繁殖,其次为‘洋大帅’,‘娇龙’、‘74-82’最不适合西花蓟马生存。西花蓟马在5个品种上的存活曲线类型不同,在‘杭椒五号’上的存活曲线偏向A型;在‘洋大帅’、‘太空辣’品种上偏向B型;在‘娇龙’、‘74-82’品种上则偏向于C型。通过种群参数分析表明西花蓟马比较喜好取食‘洋大帅’、‘太空辣’、‘杭椒五号’3个品种,‘娇龙’和‘74-82’品种则不利于西花蓟马的生长繁殖。To evaluate the occurrence and damage of Frankliniella occidentalis on different pepper varieties, five pepper cultivars were used as experiment materials to establish the life tables of F.occidentalis . According to the developmental durations of various stages,‘Hangjiaowuhao’ and ‘Taikongla’ were more suitable for the growth and reproduction of F.occidentalis , followed by ‘Yangdashuai’,‘Jiaolong’ and ‘74 82’ were not suitable for survival of F.occidentalis . The survival curves of F.occidentalis were different in the five cultivars of pepper. The survival curve of ‘Hangjiaowuhao’ was biased towards type A, and ‘Yangdashuai’ and ‘Taikongla’ were biased towards type B, while ‘Jiaolong’ and ‘74 82’ were biased towards type C. Analysis of population parameters showed that F.occidentalis preferred ‘Yangdashuai’,‘Taikongla’ and ‘Hangjiaowuhao’. However, the cultivars ‘Jiaolong’ and ‘74 82’ were not suitable for the growth and reproduction of F.occidentalis .
