摘要
在温度22～30℃，相对湿度70％～90％的条件下。以3种食料及组合研完了尼氏真绥螨的发育繁殖情况。并测定了不同螨态对朱砂叶螨不同螨态的捕食量。结果表明，利用朱砂叶螨＋花粉的组合食物更有利于尼氏真绥螨生长发育及繁殖。1个生活周期平均为7．08d；每雌平均总产卵量为42．23头，雌螨平均寿命为27．67d，雄螨平均寿命为17．03d。雌成螨对朱砂叶螨各螨态的捕食量最多，对朱砂叶螨卵、幼螨、若螨、成螨的平均捕食量分别为4．07，13．47，12．47．4．73头。
Euseius nicholsi Ehara et Lee and Teranychus cinnabarinus were reared in laboratory at 22 -30℃ and 70% ～90% RH and fed with 3 kinds of diet so as to study the development and reproduction of E. nicholsi and determine its predatory capacity on various stages of T. cinnabarinus. The results showed that T. cinnabarinus ＋ pollen was favorable to the growth of E. nwholsi, its life cycle duration and oviposition being 7.08 days and 42.24, respectively. The adult longevity of the female and the male was 27.67 and 17.03 days, respectively. The predacious number of a female adult on T. clnnabarinus eggs, larvae, nymphs and adults was 4.07, 13.47, 12.47 and 4.73, respectively.
