经测定明确，美洲斑潜蝇卵的发育起点为（８５４±１６６）℃，有效积温为（６２４０±５７９）日度；幼虫的发育起点为（８０２±２９９）℃，有效积温为（７２２１±１１８９）日度；蛹的发育起点为（１０５１±１３７）℃，有效积温为（１４１２０±１４１１）日度；卵至蛹的发育起点为（９７８±１０５）℃，有效积温为（２７０７４±１９７７）日度；成虫羽化适宜温度为２０～３０℃。
The results showed that the developmental threshold of M. occidentalis eggs was (854 ± 166) ℃, and the effective accumulated temperature was (6240 ± 579) days. The developmental threshold of larvae was (802 ± 2) 99) ℃, and the effective accumulated temperature was (7221 ± 1189) days. The developmental threshold of pupae was (1051 ± 137) ℃ and the effective accumulated temperature was (14120 ± 1411) days (978 ± 105) ℃ and effective accumulated temperature (27074 ± 1977) days respectively. The optimum temperature for adult emergence was 20 ~ 30 ℃.
