Habitat selection exploited by Chrysomya albiceps during its initial spread in Northern Italy was analyzed in relation to landscape structure. The results of two short studies and a case report are here discussed. C. albiceps was not found on experimental pig carcasses in the urban area of Pavia. It was missing in the woody mountains surrounding Lecco, but it was found in the same area, at a lower altitude, within the typical "urban sprawl" landscape. It was then recorded in a natural reserve, among a rich carrion-fly population. Indications coming from habitat selection suggest that C. albiceps has not yet saturated its potential ecological niche in newly colonized areas of Northern Italy. Factors like temperature, altitude, and interspecific competition can act as limiting factors, affecting habitat selection and distribution in newly colonized areas; the influence of those factors has to be taken into account for forensic purposes.
结合景观结构，分析了白纹丽蝇（Chrysomya albiceps）在意大利北部首次扩散期间所利用的栖息地选择。本文讨论了两项短期研究和一份病例报告的结果。在帕维亚市区的实验猪尸体上未发现白纹丽蝇。在莱科周围树木繁茂的山区未发现该物种，但在同一地区海拔较低的典型“城市扩张”景观中发现了它。随后在一个自然保护区中，在丰富的腐肉蝇种群中记录到了该物种。栖息地选择的相关迹象表明，在意大利北部新殖民地区，白纹丽蝇尚未占据其潜在的生态位。温度、海拔和种间竞争等因素可能成为限制因素，影响新殖民地区的栖息地选择和分布；出于法医目的，必须考虑这些因素的影响。
