Abstract

Nannotrigona testaceicornis (Lepeletier, 1836) is a stingless bee with wide distribution in the Brazilian territory. Despite its importance in meliponiculture and pollination, there are still few behavioral studies related to the species. The aim of this work was to characterize the recognition and defense behaviors in intraspecific bioassays carried out in N. testaceicornis colonies. Intra and inter-colonial bioassays were carried out with six colonies from different locations. The number of occurrences of each behavioral act, latency measures, and duration of confrontations were quantified. An ethogram with eight behavioral acts and two categories was elaborated. The acceptance rate was significantly higher in intra-colonial confrontations and the rejection rate was higher in inter-colonial confrontations. The rejection process was significantly higher than the acceptance process, which may be related to the specific behavioral repertoire of each process. Results indicate that the presence of an intraspecific intruder triggers an aggressive response from guards positioned in the colony access tube.

Nannotrigona testaceiconis工蜂（Lepeletier，1836）（膜翅目，蜂科）在群落内和群落间生物测定中的识别和防御行为

Nannotrigona testaceicornis (leeletier, 1836)是一种无刺蜜蜂，广泛分布于巴西境内。尽管它在棉花栽培和传粉中具有重要意义，但有关该物种的行为研究仍然很少。本研究的目的是描述在种内生物测定中对testaceicornis菌落的识别和防御行为。对来自不同地点的6个菌落进行了种群内和种群间生物测定。每个行为行为的发生次数、潜伏期测量和对抗持续时间被量化。阐述了八种行为行为和两类行为的行为谱。殖民地内对抗的接受率显著高于殖民地间对抗的拒绝率。拒绝过程显著高于接受过程，这可能与每个过程的特定行为曲目有关。结果表明，种内入侵者的存在引发了位于菌落通路管中的守卫的攻击反应。

期刊介绍： SOCIOBIOLOGY publishes high quality articles that significantly contribute to the knowledge of Entomology, with emphasis on social insects. Articles previously submitted to other journals are not accepted. SOCIOBIOLOGY publishes original research papers and invited review articles on all aspects related to the biology, evolution and systematics of social and pre-social insects (Ants, Termites, Bees and Wasps). The journal is currently expanding its scope to incorporate the publication of articles dealing with other arthropods that exhibit sociality. Articles may cover a range of subjects such as ecology, ethology, morphology, population genetics, physiology, toxicology, reproduction, sociobiology, caste differentiation as well as economic impact and pest management.
