Diploid male production of two amazonian melipona bees (Hymenoptera: Apidae)
Francini, Izaura Bezerra; Nunes-Silva, Carlos Gustavo; Carvalho-zilse, Gislene AlmeidaThe diploid male has already been recorded for Melipona Illger, and herein, in Melipona seminigra merrillae Cockerell and Melipona interrupta manaosensis Schwarz. This paper was carried out at the Instituto Nacional de Pesquisas da Amazonia (INPA), Manaus, AM, Brazil. We produced and monitored 31 new colonies of M. s. merrillae and 32 new colonies of M. i. manaosensis. We sampled 2,995 pupae of M. s. merrillae ...

Francini, Izaura Bezerra; Gross, Maria Claudia; Nunes-Silva, Carlos Gustavo; Carvalho-zilse, Gislene AlmeidaCytogenetic analysis of the Amazon stingless bee Melipona seminigra merrillae, by conventional Giemsa staining and C-banding, revealed a different chromosome number for Melipona: 2n = 22 for females and diploid drones while the haploid drones present n = 11. There is no evidence of B chromosomes. This result contrasts with previous studies, in which the chromosome number of 19 Melipona species was determined as...
