摘　　要：将神泽氏叶螨ＴｅｔｒａｎｙｃｈｕｓｋａｎｚａｗａｉＫｉｓｈｉｄａ分别置于１５℃，ＲＨ８０％；２０℃，ＲＨ７５％；２５℃，ＲＨ７０％；３０℃，ＲＨ６５％；３５℃，ＲＨ６０％的恒温恒湿箱内单个饲养，观察其个体发育、孵化率、存活率和产卵量，结果为：３５℃，ＲＨ６０％条件下，雌、雄一代发育历期最短，为（６．２３±０．４４）ｄ；成螨最高日产卵量（１３．９５±３．７２）粒；平均日产卵量（７．１８±１．５６）粒；从成螨开始产卵至死亡５０％产卵期最短，为（９．６５±１．５３）ｄ；卵孵化率７２．４％；幼螨存活率８４．６％。１５℃，ＲＨ８０％条件下，雌、雄一代发育历期最长，为（２７．４９±２．２３）ｄ；成螨最高日产卵量（５±１．２１）粒；平均日产卵量（２．０４±０．５５）粒；从成螨开始产卵至死亡５０％产卵期最长，为（２８．４±４．０６）ｄ；卵孵化率８５．６％；幼螨存活率９７．０％。１５℃，ＲＨ８０％处理成螨寿命为（３５±８．８５）ｄ，比２０℃，７５％处理成螨寿命长（１３．９±６．４）ｄ。试验结果表明，不同的温湿度对神泽氏叶螨生长发育有一定的影响，３５℃发育速率最快，１５℃发育速率最慢，２０～３０℃为最适发育温度。The duration of development, hatch rate, survival and fecundity of Tetranychus kanzawai were investigated by keeping the mites individually in the constant temhumidity cabinets of 15℃ and 80% RH, 20℃ and 75% RH, 25℃ and 70%,30℃ and 65% RH, and 35℃ and 60% RH respectively. The results showed that under 35℃ and 60% RH the mites exhibited the shortest generation (623±044)days. The average number of eggs laid per day by an adult was 718±156 with the highest number of 1395±372,and the oviposition period was (965±153) days, being the shortest. Under this condition, the hatch rate of eggs and the survival rate of young mites were 724% and 845% respectively. While under the condition of 15℃ and 80% RH the mites had the longest generation (2749±233) days, the mean number of eggs laid per day was 204±055, with the highest of 5±121, and the longest oviposition period was (284±406) days. The hatch rate of eggs and the survival rate of young mites were 856% and 970% respectively. It is manifested that the development of mites is influenced by both temperature and humidity. The mites developed faster under 35℃ but slower at 15℃, the optimal temperature for their development is considered to be within 25￣30℃.
