摘　　要：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。In 1992-1993, the resistance of four vegetable varieties tested to Tetranychus cinnabarinus was studied in Chongqing, China. The four varieties tested showed a marked influence on the growth and development, reproduction and density of the mite population, Interrari-etal differences were noticed in the resistance to the mite. In these varieties balsam pear (Monordica charantia) shoured high resistance to the mite. The mite could feed balsam pear, but the pest on balsam pear showed longer period of development, shorter longevity of the female adults, higher mortality and did not oviposit. Cowpea, eggplant and towel goural showed high susceptibility to the mite. The pest on these varieties showed shorter period of deveipment, longer longevity of the female adults, lower mortality, larger number of eggs and greater Ym, Ro and λ parameter values from life table.
