摘要 在研究温度与昆虫发育的关系中,人们往往注重平均温度的高低对昆虫发育的影响,而温变系数对昆虫发育的影响却常被忽略。笔者于1987年,用温变系数(温度标准差δ_x与平均温度(?)的比值,即δ_x/(?))对四川省南充地区森林病虫中心测报站1982-1987年的马尾松毛虫室内个体饲养资料进行了分析,试图寻找温变系数与昆虫发育速率间的关系,为松毛虫二三代分化规律的研究提供依据。 Using the propertional value of temperature standard deviation δ_x to aver-age temperature , the rearing date of Masson pine caterpillar, Dendrolimuspunctatus Walker was analyzed. The results showed temperature coefficient isan important index influencing the development of caterpillar. Within favor-able temperature range, at the same developmental stage, the average tempe-rature among the Masson pine caterpillars were close to each other, but thetemperature coefficient differesgreatly from each other. While the temperaturechanges strongly, the larvae develop slowy; while the temperature changesweakly, the larvae develop quickly. There is no significant correlation betweenthe number of generation and the annual average temperature and the decadeaverage temperature higher than 10℃; but there is very sinificant negativecorrlation between the number of generation and the coefficient of decadeaverage temperature higher than 10℃.
