摘　　要：研究了温、湿度对柑桔始叶螨Ｅｏｔｅｒａｎｙｃｈｕｓ　ｋａｎｋｉｔｕｓ　Ｅｈａｒａ发育历期和产卵量的影响．实验发现，发育历期与温、湿度呈负相关，温、湿度对发育历期的影响极为显著．每雌产卵总量与温、湿度呈抛物线型关系．通过有代表性的五个温、湿度组合试验。发现高温低温和低温高湿均不利于柑桔始叶螨的生长发育·结果表明，２０℃～３０℃为柑桔始叶螨发育的适温区间；６５％～７５％为其发育的适湿区间．The influence of temperature-humidity on the development of Eolteranychus Kankitus Ehara was studied. From the results, we find that the generation period of the mite is negatively correlated with both temperature and humidity, which influence the development of the mite significantly. The number of eggs per female is Parabola correlated with temperature and humidity. From the five representative temperature-humidity combined test, we found that high temperature with low humidity and low temperature with high humidity all So asainst to the mite's development. The results show that the optimal temperature interval for its development is consider to be within 25℃ -30℃ and the optimal humidity interval is within 65% ~ 75%.
