研究结果表明，美洲斑潜蝇的卵、幼虫、蛹、成虫的发育起点温度分别为16．82，16．56，12．82，18．16℃；有效积温分别为33．43，32．47，115．95，39．50日度。并得出各虫态的发育历期与温度的4个关系式。本资料可用于美洲斑潜蝇的发生期及世代的预测。
The results showed that the developmental threshold temperatures of eggs, larvae, pupae and adult adults were 16.82, 16.56, 12.82 and 18.16 ℃ respectively, and the effective accumulated temperatures were 33.43 and 32.47 , 115. 95, 39. 50 days. And get the relationship between developmental stages and temperature of each insect state. This information can be used to predict the occurrence and generation of L. occidentalis.
