Diploid male production of two amazonian melipona bees (Hymenoptera: Apidae)

The 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 ...

O conhecimento de substâncias repelentes para forídeos é um passo importante para a meliponicultura brasileira, pois esses insetos podem causar sérios danos às colméias de abelhas nativas. Os óleos de copaíba e andiroba, naturalmente encontrados na região amazônica, são muito utilizados pelos povos tradicionais da região como repelentes de insetos. Foi observado o efeito de dois óleos vegetais (andiroba e copaí...

Méis são descritos possuindo diferentes propriedades, incluindo a antimicrobiana. Muitos estudos têm apresentado essa atividade de méis produzidos por abelhas Apis mellifera, no entanto estudos incluindo atividades de méis de abelhas sem ferrão são escassos. O objetivo deste estudo foi comparar a atividade antimicrobiana de méis de Melipona compressipes, Melipona seminigra e A. mellifera, coletados no Estado do...

Bees for development: Brazilian survey reveals how to optimize stingless beekee...

Stingless bees are an important asset to assure plant biodiversity in many natural ecosystems, and fulfill the growing agricultural demand for pollination. However, across developing countries stingless beekeeping remains an essentially informal activity, technical knowledge is scarce, and management practices lack standardization. Here we profited from the large diversity of stingless beekeepers found in Brazi...

Molecular identification of Amazonian stingless bees using polymerase chain rea...

In countries containing a mega diversity of wildlife, such as Brazil, identifying and characterizing biological diversity is a continuous process for the scientific community, even in face of technological and scientific advances. This activity demands initiatives for the taxonomic identification of highly diverse groups, such as stingless bees, including molecular analysis strategies. This type of bee is distr...
