Phenotypic differentiation between geographic areas and between sheep and adjacent refuse tip populations was assessed by quantitative analysis of population samples of L. cuprina from New South Wales (Lismore) and Victoria (Mansfield). In addition the genetic structure of populations has been defined and compared by biometrical analysis techniques. For all morphological and fitness characters examined significant phenotypic differentiation was observed both between geographic localities and between sheep and non-sheep populations of each locality. Diallel analysis of the populations revealed architectural differences between sheep and non-sheep populations for both fecundity and egg hatchability. Sheep populations only, regardless of locality, displayed dominant gene effects on these fitness traits. The results suggest that refuse tip populations may be other than transients and that the differentiation may reflect differing patterns of adaptation and history of selection of the populations. The relevance of such differentiation to the successful establishment of a chemical and/or autocidal control zone is considered.
通过对来自新南威尔士州（利斯莫尔）和维多利亚州（曼斯菲尔德）的铜绿丽蝇种群样本进行定量分析，评估了不同地理区域之间以及绵羊和相邻垃圾场种群之间的表型差异。此外，还通过生物统计学分析技术对种群的遗传结构进行了定义和比较。对于所检查的所有形态和适应性特征，在不同地理区域之间以及每个区域的绵羊和非绵羊种群之间均观察到了显著的表型差异。对种群的双列分析揭示了绵羊和非绵羊种群在繁殖力和卵孵化率方面的结构差异。仅绵羊种群，无论地理位置如何，在这些适应性特征上均表现出显性基因效应。结果表明，垃圾场种群可能并非只是过客，这种差异可能反映了种群不同的适应模式和选择历史。还考虑了这种差异与成功建立化学和/或自灭控制区的相关性。
