| 摘 要： | 在不同的温度下,分别观察和测定了花斑皮蠹(Trogoderma variabileBallion)各虫态的发育历期、发育起点温度及有效积温。结果表明,在17.8~35℃温度范围内,花斑皮蠹均能完成发育,其发育历期随温度的升高而缩短,卵、幼虫、蛹、产卵前期的发育起点温度分别为14.5、15.9、14.6和13.6℃,有效积温分别为113.25、513.43、71.29和43.67d.℃;整个世代的发育起点温度为15.5℃,有效积温为716.76 d.℃,持续高温(37.8℃)不适合其生长发育。

| Abstract: | The developmental period(DP),developmental threshold temperature (DTT) and effective accumulated temperature(EAT) of different stages of T.variabile were determined at 17.8,22.8,27.8,32.8 and 35.The results showed that the DP of different stages of T.variabile decreases as temperature rising,The DTTs of egg,larve,pupa and pre-oviposition stages was estimated to be 14.5,15.9,14.6 and 13.6 respectively,and their EATs is 113.25,513.43,71.29 and 43.67.degree-day respectively.The DTT was 15.5 and EAT was 716.76 degree day for the whole generation.T.variabile does not adapt to temperatures higher than 37.8. |
