在4种不同温度下，比较了两个自然种群的10个同雌品系的体尺、体厚比、卵巢管数目和不同生活史性状。胸长和W/T比的三因素巢式方差分析显示温度和性别差异显著，而翅长仅显示性别差异显著。卵巢管数量的双因素巢式方差分析仅显示种群间的显著差异，而不是不同的温度。不同生活史性状之间的相关性检验显示，在不同温度下，LDT与蛹期之间以及蛹期与卵蛹DT之间存在新的权衡关系。
Ten isofemale lines of two natural populations of Drosophila ananassae were compared at four different temperatures for body size, W/T ratio, ovariole number and different life history traits. Three-factor nested ANOVA for thorax length and W/T ratio shows significant differences for temperature and sex, while for wing length it shows significant sex difference only. Two-factor nested ANOVA for ovariole number shows a significant difference between populations only, and not for different temperatures. Tests of correlations among different life history traits show novel trade-offs between LDT and pupal period and between pupal period and egg–pupa DT at different temperatures.
