研究了 9个梯度变温对湿地松粉蚧Oracellaacuta (Lobdell)越冬代成虫和第一代卵的影响 ,结果表明 :湿地松粉蚧雌成虫存活率随温度升高逐渐下降 ,高温对成虫产卵有一定抑制作用 ,持续较高温度处理成虫 ,其产卵量显著降低 ;湿地松粉蚧成虫生长发育的最适温度为 2 7～ 2 1℃ ,卵的孵化和发育的最适变温组合是 2 9～ 2 3℃ ;在 2 9～2 3℃以上的温度波动对卵的发育速率有增速作用 ,而在 2 9～ 2 3℃以下的温度波动对卵的发育速率则有减速作用 The results showed that the survival rate of female adults of Sophora alopecusta decreased gradually with the increase of temperature, and the effects of high temperature on oviposition of adult larvae of Oracellaacuta (Lobdell) And the oviposition rate of mature adults of Ixodes mariquee was 27 ~ 21 ℃. The optimal temperature combination of hatching and development of eggs was 29 ~ 2 3 ℃. The temperature fluctuation above 29 ~ 23 ℃ increased the growth rate of eggs, while the temperature fluctuation below 29 ~ 23 ℃ retarded the development rate of eggs
