The Neotropical stingless bee Melipona quadrifasciata has two subspecies: M. quadrifasciata quadrifasciata and M. quadrifasciata anthidioides. The main difference between sub- species are the yellow metassomal stripes, which are continuous in M. q. quadrifasciata and discontinuous in M. q. anthidioides. Recently, two populations were described with continuous stripes and inhabiting clearly disjunct areas in relation to M. q. quadrifasciata. We sequenced 852 bp of the mtDNA COI gene from 145 colonies from 56 localities, and for the first time performed a detailed phylogeographic study of a neotropical stingless bee. Phylogenetic analyses revealed the existence of two clades exhibiting a south to north distribution: southern populations comprise the subspecies M. q. quadrifasciata, and northern pop- ulations are composed of M. q. anthidioides and two disjunct populations with continuous stripes. The divergence time of these two phylogroups was estimated between 0.233 and 0.840 million years ago in the Pleistocene, a period of climatic changes and geomorphological alterations in the Neotropical region. No evidence of genetic structure in relation to the tergal stripes was found, indicating that the morpho- logical trait regarding the pattern of stripes on tergites is not an accurate diagnostic for the subspecies of M. quadrifasciata. biogeography / coalescence / tergal stripes / Melipona quadrifasciata / subspecies 1.

We tested this with feeders up to 140 m away from the hive. Foragers of M. scutellaris communicated direction (up to 140 m) more accurately than distance (up to 30 m) whereas those of M. quadrifasciata communicated direction only up to 30 m and distance up to 40 m. Our data indicate that in both species recruitment is divided into two temporal phases. Whereas in an initial phase alarmed nestmates search for food at random, bees leaving the hive in the fol- lowing phase are obviously provided with information about its specific location. As a consequence after 35 minutes (M. scutellaris) and 85 minutes (M. quadrifasciata), respectively, significantly more newcomers arrive at the feeder than at an identical control feeder. The differences found in the recruitment success of M. scutellaris and M. quadrifasciata are discussed in regard to the different demands of their natural habitats. stingless bee / foraging / recruitment / direction and distance communication / Melipona species * Correspondence and reprints E-mail: [email protected] 82 S.

We investigated hygienic behavior in 10 colonies of Plebeia remota, using the pin-killed method. After 24 h the bees had removed a mean of 69.6% of the dead brood. After 48 h, the bees had removed a mean of 96.4% of the dead brood. No significant correlation was found between the size of the brood comb and the number of dead pupae removed, and there was no apparent effect of the origin and the condition of the colony on the hygienic behavior of the bees. Plebeia remota has an efficiency of hygienic behavior superior to that of three of the other four stingless bee species studied until now.

Nunes-Silva et al. 650 INTRODUCTION Apis mellifera workers are capable of detecting diseased, infected, damaged or dead brood, uncapping the cells and removing the affected larvae and pupae. This capa- bility is known as hygienic behavior (Rothenbuhler, 1964a,b); since this behavior makes honey bees more resistant to diseases and parasites, it has become of great interest for apiculture (see Boecking and Spivak, 1999).

  • Genetic Divergence Between Melipona Quadrifasciata Lepeletier (Hymenoptera, Apidae) Populations
    Genetics and Molecular Biology, 36, 1, 111-117 (2013) Copyright © 2013, Sociedade Brasileira de Genética. Printed in Brazil www.sbg.org.br Research Article Genetic divergence between Melipona quadrifasciata Lepeletier (Hymenoptera, Apidae) populations Mara Garcia Tavares, Nathalia Teixeira Pietrani, Maxwell de Castro Durvale, Helder Canto Resende and Lucio Antonio de Oliveira Campos Departamento de Biologia Geral, Universidade Federal de Viçosa, Viçosa, MG, Brazil. Abstract Melipona quadrifasciata is a stingless bee widely found throughout the Brazilian territory, with two recognized sub- species, M. quadrifasciata anthidioides, that exhibits interrupted metasomal stripes, and M. quadrifasciata quadrifasciata, with continuous metasomal stripes. This study aimed to estimate the genetic variability of these sub- species. For this purpose, 127 colonies from 15 Brazilian localities were analyzed, using nine species-specific microsatellite primers. At these loci, the number of alleles ranged from three to 15 (mean: 7.2), and the observed heterozygosity (Ho) ranged from 0.03-0.21, while the expected heterozygosity (He) ranged from 0.23-0.47. The ge- netic distances among populations ranged from 0.03-0.45. The FST multilocus value (0.23) indicated that the popula- tions sampled were structured, and the clustering analysis showed the formation of two subgroups and two more distant populations. The first group contained the subspecies M. quadrifasciata quadrifasciata, and the other, the subspecies M. quadrifasciata anthidioides and the two M. quadrifasciata populations with continuous metasomal stripes from northern Minas Gerais. These results confirmed that the yellow metasomal stripes alone are not a good means for correctly identifying the different subspecies of M. quadrifasciata. Keywords: genetic differentiation, microsatellites, population genetics, stingless bees.

  • Tree Species Used for Nidification by Stingless Bees in the Brazilian Caatinga (Seridó, Pb; João Câmara, Rn)
    TREE SPECIES USED FOR NIDIFICATION BY STINGLESS BEES IN THE BRAZILIAN CAATINGA (SERIDÓ, PB; JOÃO CÂMARA, RN) Celso Feitosa Martins1, Marilda Cortopassi-Laurino2, Dirk Koedam2 & Vera Lúcia Imperatriz-Fonseca2 Biota Neotropica v4(n2) – http://www.biotaneotropica.org.br/v4n2/en/abstract?article+BN00104022004 date received: 12/15/2003 revised: 06/10/2004 accepted: 07/01/2004 1Departamento de Sistemática e Ecologia/CCEN, Universidade Federal da Paraíba (UFPB). 58059-900, João Pessoa, PB, Brasil. http://www.ufpb.br e-mail: [email protected] (autor para correspondência). 2Departamento de Ecologia, Instituto de Biociências, Universidade de S. Paulo (USP) 05508-900, São Paulo, SP, Brasil. http://www.usp.br Abstract In Rio Grande do Norte, a caatinga region of North-eastern Brazil, the nesting opportunities that trees offer to stingless bees (Meliponinae) were studied. Samples consisted mostly of tree trunks, which were kept by Meliponinae beekeepers. Nearly 13 per cent of observed nests were in living trees in the field. Seven species of stingless bees, totalling 227 nests, were encountered in 12 tree species. More than 75.0% of stingless bees were found in two tree species being Caesalpinia pyramidalis (Caesalpiniaceae, 41.9%) and Commiphora leptophloeos (Burseraceae, 33.9%). Furthermore, all bee species nidify in C. pyramidalis. A great part of the nests in trunks were of Melipona subnitida, (N = 130) of which 50.0% was found in C. leptophloeos and 22.3% in C. pyramidalis. M. asilvai was predominantly found in C. pyramidalis (92.3%, N = 39). Besides this survey was mainly directed to bee species with beekeping importance, data shows the huge relevance of these two plant species for nesting by stingless bees in the caatinga.
