摘　　要：室内观察测定5个恒温条件下,核桃扁叶甲Gastrolina depressa Baly各虫态的发育历期及起点温度和有效积温。结果表明:在16～32℃温度范围内,核桃扁叶甲均能完成发育,其发育历期随温度的升高而缩短,卵期、幼虫期、蛹期、产卵前期的发育起点温度分别为9.4,12.2,14.3和11.1℃,有效积温分别为43.2,77.2,36.0和104.7日.度;整个世代的发育起点温度为12.0℃,有效积温为260.5日.度。持续过高温度不适合核桃扁叶甲的生长发育。The developmental duration （DD）, developmental threshold temperature （DTF） and effective accumulated temperature （EAT） of different stages of Gastrolina depressa Baly were determined at 16,20,24,28 and 32℃. The results showed that the DD of different stages of G. depressa shortened as temperature rising. The DTT of egg, larva, pupa and pre-oviposition stages was estimated to be 9.4, 12.2, 14.3 and 11.1℃ respectively, and their EAT was 43.2,77.2,36.0 and 104.7 degree-day respectively. The DTT was 12.0℃ and EAT was 260.5 degree-day for the whole generation. G. depressa does not adapt to temperatures higher than 32℃ .
