南美斑潜蝇发育起点温度和有效积温的研究

Threshold temperature and effective temperature sum of Liriomyza huidobrensis.

在恒温条件下 ,观察了不同温度对南美斑潜蝇LiriomyzahuidobrensisBlanchard生长发育的影响 ,并用直线回归法测得卵、幼虫、蛹和全世代的发育起点温度分别为 7 2℃ ,7 4℃ ,7 7℃和 7 5℃ ,有效积温分别为 4 0 8,98 6 ,1 4 0 5和 2 79

The developmental rate of Liriomyza huidobrensis Blanchard was determined at constant temperatures .The threshold temperatures for egg,larva,pupa and the whole generation of the fly were estimated to be 7.2,7.4,7.7,7.5℃,and the effective temperature sums for these stages were assessed as 40.8,98.6,140.5,279.9 degree-day, respectively.
