Abstract

Blepharidatta is a rare Neotropical ant genus in the Attini tribe of the subfamily Myrmicinae. It has only four valid species and among them Blepharidatta delabiei was recently described and there is little knowledge on its biology. This study is the first cytogenetic characterization for the genus Blepharidatta and also presents the biology of B. delabiei. Cytogenetic analyses revealed a karyotype 2n = 28 with acrocentric and metacentric chromosomes and a karyotypic formula (m: metacentric, a: acrocentric): 2K = 16m + 12a. We observed that ants of this species have diurnal habits with higher foraging activity in the afternoon and are possibly omnivorous as they accepted the baits used. The distance between colonies varied from 5 to 7 meters.

1915年，首次通过常规染色对蚂蚁属Blepharidata Wheeler进行细胞遗传学研究（膜翅目：蚁科：Attini）

Blepharidatta是蚁亚科蚁族中罕见的新热带蚁属。它只有四个有效的物种，其中Blepharidatta delabiei是最近被描述的，对它的生物学知之甚少。本研究首次对Blepharidatta属进行了细胞遗传学鉴定，并介绍了该属的生物学特性。细胞遗传学分析显示，该染色体核型为2n = 28，染色体为多中心和多中心，核型公式为(m:多中心，a:多中心):2K = 16m + 12a。我们观察到，该物种的蚂蚁具有白天的习性，觅食活动在下午较高，并且可能是杂食性的，因为它们接受了所使用的诱饵。蚁群之间的距离从5米到7米不等。

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.
