我们使用了5个果蝇经常F1调查基因型差异的空间使用和运动模式，专注于teneral女性和单独标记的年轻成年人，允许自由进入大型，结构复杂的环境的行为。从五个F1的一般女性不同的倾向，隐藏后出现，并在他们栖息在基板以上的高度。在前2周的成年生活中，F1的两性表现出一致的差异，在网站的保真度，所花费的时间在位于远离食品的地区的比例，和他们的选择基板栖息时，食品附近。作为幼虫，这相同的五个F1不同的觅食时，距离移动干扰后，在纳塔尔的水果，化蛹距离纳塔尔的水果。这项研究的结果可能有助于阐明涉及该物种的相关问题，包括纳塔尔经验对栖息地偏好的影响，以及化蛹场所附近的结构特征对teneral女性避免捕食者或强迫交配的能力的影响。(c)2005年，动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
We used five Drosophila melanogaster recurrent F1s to investigate genotypic differences in space use and movement patterns, focusing on the behaviour of teneral females and individually marked young adults that were allowed free access to large, structurally complex environments. Teneral females from the five F1s differed in their propensity to hide after emergence and in the height at which they perched above the substrate. During the first 2 weeks of adult life, F1s of both sexes showed consistent differences in site fidelity, the proportion of time spent in areas located far from food items, and their choice of substrate when perching near food items. As larvae, these same five F1s differed with respect to the distances travelled while foraging, distances moved after disturbance at natal fruits, and pupation distance from natal fruits. The results of this study may help to shed light on related questions involving this species, including the effects of natal experience on habitat preference, and the effect of structural features near pupation sites on the ability of teneral females to avoid predators or forced copulations.
