摘要/Abstract

摘要： 在17、20、24、28 和32 ℃条件下,研究温度对防治柽柳的植食性昆虫斯氏伞锥象发育历
期的影响。用线性方程拟合了斯氏伞锥象发育速率与温度间的关系式。用直线回归法计算出
卵、幼虫、预蛹、蛹、产卵前期成虫及全世代的发育起点温度,依次为13.48、12.48、10.32、13.28、8.71 和11.44 ℃,有效积温依次为:46.52、121.52、31.70、62.17、186.19 和445.78 日度。并推算出斯氏伞锥象理论年发生代数为3.24 代。

Abstract: The effects of temperature on development of Coniatus steveni(Curculionidae , Coleoptera)were studied under a range of constant temperatures (17 , 20 , 24 , 28 and 32 ℃) in the laboratory. Therelationships between temperatures and development rate of each life stage were fitted with linear model .The development threshold temperatures for egg , larva , prepupa , pupa , pre2oviposition adult , and whole generation were 13148 , 12148 , 10132 , 13128 , 8171 and 11144 ℃, respectively. The effective degree- days for the development of each life stage were 46.52 for egg , 121.52 for larva , 31.70 for prepupa , 62.17 for pupa , 186.19 for pre-ovipostional adult , and 445.78 for whole generation from egg to pre-ovipositional adult . And theoretical number of generations was reckoned at 3.24 generations.
