对西西里岛4个海拔的成年Calliphoravicina(Robineau-Desvoidy)的右翼进行了几何形态分析。这项研究的目的是评估女性和男性之间以及跨海拔的形状和质心大小(CS)的差异。在这项研究中分析的翅膀是从用诱饵诱捕器收集的20、700、1,153和1,552的C.vicina成虫中取出的;对于这项研究,在每个机翼中确定了19个地标。地标的坐标对齐和叠加,以防止由于位置的变化,定位,和缩放;然后将它们缩放为相同的CS并重新定位。CS和Procrustes的差异是,分别,用于评估大小和形状的变化。男性和女性之间的机翼形状存在显着差异,但在所有海拔水平之间均未观察到。发现雌性翅膀明显大于雄性(P<0.01)。在最高海拔收集的苍蝇的翅膀比在低海拔收集的翅膀明显更大(P<0.001),CS值范围从12.1到14.1。机翼形状的变化会影响热调节,因此,氧含量,温度,大气压力,太阳辐射会对昆虫的身体和活动水平产生影响。在高海拔和较低温度下,更大的翅膀可能意味着在飞行时增加体温的能量消耗更少。
A geometric morphometric analysis was performed on the right wing of adult Calliphora vicina (Robineau-Desvoidy) collected across 4 altitudinal levels in Sicily. The objective of this study was to assess differences in shape and centroid size (CS) between females and males and across elevations. The wings analyzed in this study were removed from adults of C. vicina collected with baited traps at 20, 700, 1,153, and 1,552; for this study, 19 landmarks were identified in each wing. The coordinates of the landmarks were aligned and superimposed to prevent variations due to position, orientation, and scale; they were then scaled to the same CS and recentered. CS and Procrustes differences were, respectively, used to assess variations in size and shape. Significant differences were observed in wing shape between males and females but not between all altitudinal levels. Female wings were found to be significantly larger than males (P < 0.01). Wings of flies collected at the highest altitudinal level resulted in significantly larger wings than those collected at lower altitudes (P < 0.001), with CS values ranging from 12.1 to 14.1. Variation in wing shape can impact thermal regulation, and therefore, oxygen content, temperature, atmospheric pressure, and solar radiation can have an effect on an insect\'s body and activity levels. At high elevations and lower temperatures, larger wings could mean less energy expenditure when flying to increase body temperature.
