Determination of developmental threshold temperature and effective accumulative temperature of Eucryptorrhynchus chinensis
摘要
Abstract
To further understand the bio⁃ecological characteristics of Eucryptorrhynchus chinensis ( Olivier) , the develop⁃mental threshold temperature and effective accumulated temperature of E. chinensis were determined under natural chan⁃ging temperature in the laboratory, and the forecasting formula of E. chinensis were obtained. The results showed that the developmental threshold temperatures of egg, larval and pupae were 8�84, 15.37 and 5.95℃, respectively,and their effec⁃tive accumulative temperatures were 190�50, 667�06 and 322.50℃·d, respectively. Their forecasting formulas were:Negg=190�50±27�81/T-(8�84±0�66);Nlarval=667�06±92�29/T-(15�37±1�4);Npupae=322�50±32�37/T-(5�95±1�63). Through woodland verification, it was proved that the forecasting formulas of E. chinensis for egg and pupae stage were fea⁃sible. Although the forecasting formula of larval stage has some deviations, it can also provide guidance for forecasting.关键词
