Abstract

Tetrapedia diversipes Klug (Apidae) is a solitary bee with wide geographical distribution. Females of this species usually nest in pre-existing cavities and although their biology is relatively well known, studies on their trophic niche are still scarce. Thus, the present study aimed to identify the plant species used in the diet of immature T. diversipes through the analysis of residual pollen material. The nests used in the study were obtained through the use of trap nests during the period between December 2014 and October 2015, distributed in an area of coastal forest in northeastern Brazil. For the study of the trophic niche, samples of post-emergency residue (feces) from cells of offspring of males (n = 31) and females (n = 66) of T. diversipes were analyzed. In total, 29 pollen types were identified in the feeding of T. diversipes, being of the pollen types identified, only seven were not used by both sexes. Although a significant difference was found in the amplitude in the trophic niche between the sexes, there was a high overlap for Horn-Morisita index (CH = 0.989), with no significant difference being found in the frequency distribution of male and female food items (D = 0.214; p = 0.341). In this study we concluded that the diet of T. diversipes in coastal forest is polyletic, similarly to the pattern found in other studies of pollen resources in different vegetation in Brazil, with a predominance of pollen from the families Euphorbiaceae, Asteraceae and Onagraceae.

巴西半落叶低地林中小蜂属的花粉生态位(膜翅目:小蜂科:小蜂属)
胡蜂(Apidae)是一种分布广泛的独居蜂。该物种的雌性通常在预先存在的洞穴中筑巢,尽管它们的生物学相对众所周知,但对其营养生态位的研究仍然很少。因此,本研究旨在通过对残留花粉物质的分析,确定未成熟多样性T.diversipes日粮中使用的植物种类。研究中使用的巢穴是在2014年12月至2015年10月期间通过使用陷阱巢穴获得的,分布在巴西东北部的沿海森林地区。为了研究营养生态位,分析了来自多样性T.diversipes雄性(n=31)和雌性(n=66)后代细胞的应急后残留物(粪便)样本。在已鉴定的花粉类型中,只有7种不被两性使用。尽管性别之间的营养生态位幅度存在显著差异,但Horn Morisita指数存在高度重叠(CH=0.989),雄性和雌性食物的频率分布没有显著差异(D=0.214;p=0.341),与巴西不同植被花粉资源的其他研究中发现的模式相似,主要来自大戟科、菊科和小檗科的花粉。

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.
