摘要
在不同恒温条件下测定了南美斑潜蝇的发育历期。采用直线回归法计算出卵、幼虫、蛹和整个世代的发育起点温度分别为 7 9、6 2、7 5、和 7 0℃ ,有效积温分别为 42 6、98 5、1 47 9和 2 91 7日度。在乌鲁木齐地区 1年可发生 7代。
The developmental periods of Liriomyza huidobrensis Blanchard were determined at five kinds of constant temperatures.The developmental thresholds and effective temperature of egg,larva,pupa and total life cycle were determined as 7.9,6.2,7.5,7.0℃,42.6,98.5,147.9,291.7 degree-days by applying the linear regression method,respectively.Based on thirteen years meteorological data,it was suggested that there might be 7 generations of this insect pest per year in Wrumqi.
