| 摘 要： | 在28℃下用叶盘法研究了５种寄主植物对截形叶螨生长发育及繁殖的影响。结果表明，在不同寄主植物上，截形叶螨各螨态历期、单雌产卵量、日均产卵量、产卵期、净增殖率、周限增长率、内禀增长率、世代平均周期和种群加倍时间等均有明显差异; 雌螨完成一代所需时间长短依次为9.3天（黄瓜）、9.3天（菜豆）、9.6天（大豆）、11.0天（茄子）和11.6天（玉米），产卵期依次为9.9天（茄子）、11.2天（黄瓜）、12.9天（菜豆）、15.8天（玉米）和17.9天（大豆）；单雌产卵量和净增殖率在大豆上最高，分别为115.0和51.7，而在茄子上最低，分别为38.0和11.7。幼、若螨期存活率大小依次为93.6%（大豆）、91.7%（玉米）、89.9%（黄瓜）、84.3%（菜豆）和61.6%（茄子），存活曲线均为Ⅰ型。大豆是其最嗜食寄主植物，其次是玉米，再次为黄瓜和菜豆，对茄子的嗜食性最差。

| Abstract: | Influence of five host plants on development and reproduction of Tetranychus truncatus Ehara was investigated at 28℃ in the laboratory. The results Indicated that there were significant differences in the durations of different developmental stages, fecundity, egg production per day, net reproductive rate (R0), finite rate of increase (λ), intrinsic rate of increase (rm), mean generation time (T) and the days needed to double population size (DDP) when reared with these host plants. The time needed by females to complete a generation on cucumber, kidney bean, soybean, eggplant and corn were 9.3, 9.3, 9.6, 11.0 and 11.6 days, respectively. The viposition time lasted 9.9, 11.2, 12.9, 15.8 and 17.9 days, respectively on eggplant, cucumber, kidney bean, corn and soybean. Both fecundity and R0 of the mite were the highest on soybean, and the lowest on eggplant. The survival rates on soybean, corn, cucumber, kidney bean and eggplant were 93.6%, 91.7%, 89.8%, 84.3% and 61.6%, respectively. The survival curves fell into DeeveyⅠ. The mite displayed a decreasing preference on the five host plants in the following order: soybean, corn, cucumber, kidney bean and eggplant. |
