阿根廷蚂蚁，Linepithema humile，是一种广泛的入侵物种，其特点是减少种内侵略引进人口。为了阐明阿根廷蚂蚁的巢友识别机制，我们研究了种内侵略的空间和时间的保真度在阿根廷蚂蚁的引进人口内种内侵略确实发生。我们量化的变化，在存在或不存在的种内侵略之间的巢随着时间的推移，在现场和受控的实验室条件下，以深入了解环境因素的作用，作为巢友的歧视能力的决定因素。此外，我们比较了巢对之间的种内侵略的相似性，他们的表皮碳氢化合物，以确定这些化合物作为标签的巢友歧视的潜在作用。在现场和实验室的比较中，巢对在整个实验过程中表现出一致的方式：对战斗这样做了整整一年，和，对没有战斗保持非侵略性。此外，我们发现表皮碳氢化合物的相似性和巢之间的侵略程度呈负相关关系，这表明这些碳氢化合物在巢友判别能力中发挥作用。与普遍的模式相反，在研究过程中，一个地点的蚂蚁表现出明显的行为变化。伴随的变化也被认为是在表皮碳氢化合物配置文件的蚂蚁从这个网站。(C)2002年，动物行为研究协会。由爱思唯尔科技有限公司出版。保留所有权利。
The Argentine ant, Linepithema humile, is a widespread invasive species characterized by reduced intraspecific aggression within introduced populations. To illuminate the mechanisms underlying nestmate recognition in Argentine ants, we studied the spatial and temporal fidelity of intraspecific aggression in an introduced population of Argentine ants within which intraspecific aggression does occur. We quantified variation in the presence or absence of intraspecific aggression among nests over time both in the field and under controlled laboratory conditions to gain insight into the role of environmental factors as determinants of nestmate discriminatory ability. In addition, we compared levels of intraspecific aggression between nest pairs to the similarity of their cuticular hydrocarbons to determine the potential role of these compounds as labels for nestmate discrimination. In both field and laboratory comparisons, nest pairs behaved in a consistent manner throughout the course of the experiment: pairs that fought did so for an entire year, and, pairs that did not fight remained nonaggressive. Moreover, we found a negative relationship between cuticular hydrocarbon similarity and the degree of aggression between nests, suggesting that these hydrocarbons play a role in nestmate discriminatory ability. In contrast to the prevailing pattern, ants from one site showed a marked change in behaviour during the course of this study. A concomitant change was also seen in the cuticular hydrocarbon profiles of ants from this site. (C) 2002 The Association for the Study of Animal Behaviour. Published by Elsevier Science Ltd.
