4种供试蔬菜品种对朱砂叶螨Tetranychus cinnabarinus (Boisduval)种群生长发育、繁殖及种群密度有明显影响,品种间存在抗螨性差异。其中苦瓜抗螨性强,丝瓜、茄子、豇豆则表现出不同程度的感螨性。朱砂叶螨能够取食苦瓜叶片,但发育历期延长,雌成螨寿命缩短,死亡率较高,而且在苦瓜上不产卵。朱砂叶螨在豇豆、茄子、丝瓜上,发育历期短,雌成螨寿命长,产卵量大,死亡率低,R_o、γ_m、λ等生命表参数值较大。
The tested vegetables had significant effects on the population growth, reproduction and population density of Tetranychus cinnabarinus (Boisduval) population, and there were differences in anti-mite among the cultivars. Bitter gourd, which has strong anti-mite, loofah, eggplant, cowpea showed different levels of mites. Tetranychus cinnabarinus can take bitter gourd leaves, but the developmental duration, female adult mites shorter life expectancy, higher mortality, but does not spawn on bitter melon. On the cowpea, eggplant and sponge gourd, the spider mites of Tetranychus cinnabarinus had short developmental duration, long adult fecundity, large amount of spawning and low mortality, and the life table parameters such as R_o, γ_m and λ were relatively large.
