The influence of gradient temperature on survival and oviposition of the over-wintering female adults of Crisicoccus pini,egg incubation and worm development was studied and some conclusions were drawn as follows:The survival rate of the female adults dropped as the temperature rose within a certain temperature range,and the female adults could not survive for a long period under 2935 .
研究了9个梯度变温对松白粉蚧越冬代成虫和第一代卵的影响,结果表明:松白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的抑制作用,持续较高温度处理成虫,其产卵量显著减少;松白粉蚧成虫生长发育的最适温度为19~24℃,卵孵化和发育的最适变温组合为21~26℃;在21~26℃以上的温度波动对卵的发育速率有增效作用,而在21~26℃以下的温度波动对卵的发育速率则有减速作用。
The results indicated that the temperature significantly affected the mortality of the overwintering adults,oviposition amount and hatchability.
结果表明:温度对松白粉蚧越冬代成虫死亡率、产卵量、卵孵化率有显著影响。
The weight,length and oviposition amount of adults in the late stage of oviposition were measured and adults were bred in 1999 at the constant temperatures and varied temperatures in lab in Hefei.
