美洲斑潜蝇发育起点温度及有效积温研究

设置6个温度12个湿度对美洲斑潜蝇卵、幼虫、蛹的发育速率进行了测定，结果表明：温度是影响孩虫发育的最重要因素；分别运用直线回归法和优选法计算发育起点温度和有效积温，结果是优选法的精确度较高；用优选法所得卵、幼虫、蛹和全世代的发育起点温度分别为9．2、6．4、10．8、11．0℃，有效积温分别为4O．2、78．0、129．0、218．9日度。

Studies on the developmental zero and effective accumulated temperature and thermal constant of Liriomyza sativae Blanchard

The tempetalure was more important factor affecting the rate of development of Driomyza sativae Blanchard than the moisture determined at 6 constant temperature and 12 moisture cases. Using the optimum seeking method and the linear regression method to anayse the experimental data,the formerwas better.The base developmnt temperatures, 9.2, 6.4.10.8, 11℃,and the thermal constants,40.2, 78.0. 129.0. 218.9d℃ for eggs, larvae.Pupae and the whole generation, respectively, were computed by the former.
