ABSTRACT Until now almost nothing was known of invertebrates such as wild bees in the Bamenda highland forest region in Cameroon. This study focuses on honey producing bee species which do not possess functional stings. The diversity of the stingless bees in this area as well as their nest biology and behaviour was studied. In all, Six species of stingless bees grouped into four genera exist in the Bamenda afro-montane forests. The four genera are: Meliponula (3 species), Dactylurina (1species), Hypotrigona (1 species) and Liotrigona (1species). The most represented of the species in Bamenda was Liotrigona. Stingless bees were found to have huge variations in habitat preferences and in nest architectures. Nest designs differ with species as well as the habitats. Nest were found in tree trunks, mud walls, traditional hives, in soils or even just attached to tree branches. Brood cells and storage pots differ from species to species. -

Cytogenetic Characterization of Two Species of Frieseomelitta Ihering, 1912 (Hymenoptera, Apidae, Meliponini)
Genetics and Molecular Biology, 34, 2, 237-239 (2011) Copyright © 2011, Sociedade Brasileira de Genética. Printed in Brazil www.sbg.org.br Short Communication Cytogenetic characterization of two species of Frieseomelitta Ihering, 1912 (Hymenoptera, Apidae, Meliponini) Antônio F. Carvalho and Marco Antônio Costa Universidade Estadual de Santa Cruz, Departamento de Ciências Biológicas, Ilhéus, Bahia, Brazil. Abstract The cytogenetic analysis of Frieseomelitta dispar and F. francoi revealed the chromosome numbers 2n = 30 and n = 15 and a karyotypic formula 2K = 4M+2Mt+4A+20AM. The number of chromosomes observed was consistent with those reported for other Frieseomelitta species. The occurrence of the Mt chromosome and other features of the karyotype formulae suggest a close relationship between F. dispar, F. francoi and F. varia. Nevertheless, it was pos- sible to differentiate the karyotypes of the species by DAPI/CMA3 staining, which revealed GC-rich regions on two chromosome pairs of F. dispar: one acrocentric and one pseudoacrocentric. In F. francoi, the same kinds of regions were observed on a pair of metacentrics and on a pair of acrocentrics. Our analysis also confirmed the chromosome number conservation in Frieseomelitta and suggests that infrequent pericentric inversion could constitute a synapomorphy for the group including F. dispar, F. francoi, and F. varia. Key words: Hymenoptera, Frieseomelitta, interspecific differentiation, C-banding, heterochromatin. Received: July 15, 2010; Accepted: December 21, 2010. Frieseomelitta is comprised of 16 species (Moure et Metaphases of 20 individuals from each nest were ob- al., 2007) of which only five have been cytogenetically an- tained from cerebral ganglion cells at the prepupal stage. -

REGULAR PAPER COMPARATIVE ULTRASTRUCTURE OF THE MANDIBULAR GLAND IN Scaptotrigona postica (HYMENOPTERA, APIDAE, MELIPONINI) WORKERS AND MALES Luciana Fioretti Gracioli-Vitti1 and Fábio Camargo Abdalla2 1Department of Biology, Institute of Biosciences, Paulista State University (UNESP), Rio Claro and 2Department of Biology, Federal University of São Carlos (UFSCar), Sorocaba, SP, Brazil. ABSTRACT Differences in the ultrastructure and function of the mandibular glands in developing workers and mature males of the meliponine stingless bee Scaptotrigona postica suggest that there are age-dependent variations in the contents of the secretion and glandular functions. In this work, we used transmission (TEM) and scanning (SEM) electron microscopy to examine the mandibular glands of S. postica workers of different ages and compared them with those of mature males. The gland anatomy did not vary between workers and males. However, the ultrastructure of the gland cells changed according to the worker’s age, task, and sex. The mandibular gland cells in workers and males had a well developed smooth endoplasmic reticulum and pleomorphic mitochondria, indicating that the cells were involved in lipid synthesis. However, the secretion varied in morphology and electrondensity between workers and males, which suggested differences in its contents and, possibly, in glandular functions.

The impact of agricultural colonization and subsequent 17 deforestation on species composition and richness is explored. Deforestation, around each 18 of 187 sample sites, was characterized at meso, micro, and local spatial scales. At the 19 micro-scale, deforestation was measured using a data layer generated by satellite remote 20 sensing and analyzed with the assistance of a geographic information system. We report 21 perhaps the greatest richness of stingless bees ever recorded in the tropics, collecting 22 9,555 individuals from 98 species of stingless bees. Ten of these are new species and 16 23 were first-ever records for Rondônia. Five new species were scientifically described from 1 24 the study. We report statistical relationships between deforestation and species richness at 25 all spatial scales of analysis, and we tentatively identify species that appear to be 26 especially sensitive to deforestation. 27 28 Key-words: social bees; redundancy analysis; forest fragmentation; land use; 29 Amazon 30 2 31 1. -

Lizot (1977) argues that it has been wrongly supposed, without taking into account regional variations, that game resources and protein supplies are limited in the Amazonian forests. He suggests from a study of two local groups of Yanomami, the Karohi and the Kakashiwë, that food requirements are satisfied by a very moderate amount of work and that variations in the level of consumption depend more on attitudes toward work than on the supply of game. -

To test for phylogenetic association of behavioral traits for species of the Neotropical stingless bee genus Trigona s.s., a phylogenetic hypothesis was generated by combining sequence data of 24 taxa from one mitochondrial (16S rRNA) and four nuclear gene fragments (long-wavelength rhodopsin copy 1 (opsin), elongation factor-1α copy F2, arginine kinase, and 28S rRNA). Fifteen characteristics of the nest architec- ture were coded and tested for phylogenetic association. Several characters have significant phylogenetic signal, including type of nesting substrate, nest construction material, and hemipterophily, the tending of hemipteroid insects in exchange for sugar excretions. Phylogenetic independent habits encountered in Trig- ona s.s. include coprophily and necrophagy. molecular phylogeny / neotropical / stingless bee / behavior / nest 1.
