摘要: 为进一步了解沟眶象生物生态学特性,在室内自然变温条件下,对其发育起点温度和有效积温进行测定,并得出相应各虫态的历期预测式。结果表明:沟眶象卵(egg)、幼虫(larval)、蛹(pupae)发育起点温度分别为8.84、15.37、5.95 ℃,各发育期有效积温分别为190.50、667.06、322.50 ℃·d。沟眶象各虫态历期预测式分别为: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)。经林间验证,各预测式在沟眶象卵期、蛹期较为可行,幼虫期虽有一定偏差,但可以为预测预报提供指导。

Abstract: To further understand the bio-ecological characteristics of Eucryptorrhynchus chinensis(Olivier), the developmental threshold temperature and effective accumulated temperature of E. chinensis were determined under natural changing 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 effective 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 feasible. Although the forecasting formula of larval stage has some deviations, it can also provide guidance for forecasting.
