中文摘要: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,
英文摘要:The developmental duration (DD), developmental threshold temperature (DTT) 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
