Sex Determination in Bees (Apinae)

Journal of Apicultural Research, 1967
SUMMARYInbred lines of 7 species of social bees were studied, and checked for the presence of diploid male larvae: 7 lines of Apis mellifera, and 15 of Meliponini, representing 6 species. In 3 lines of Apis mellifera showing 50% viability, the non-surviving larvae were males, but diploid males could have some female-like characters. None of the species

Ingesting microplastics or nanometals during development harms the tropical pollinator Partamona helleri (Apinae: Meliponini)

Science of The Total Environment, 2023
The disposal of plastics and metal-derived compounds results in the contamination of the environment with nano/microparticles, leading to the exposure of various organisms to these harmful particles. However, the impacts of these particles on pollinating insects, which provide relevant ecosystem services, are not well understood.

Ultrastructural characterization of spermatozoa in euglossine bees (Hymenoptera, Apidae, Apinae)

Insectes Sociaux, 2005
Euglossine spermatozoa are the longest described to date for the Hymenoptera. This cell includes a head and a flagellar region. In transverse sections, the acrosome is circular at the tip but has an oval contour along most of its length. The perforatorium penetrates into a deep cavity in the nuclear tip.

First record of emergency queen rearing in stingless bees (Hymenoptera, Apinae, Meliponini)

Insectes Sociaux, 2002
This paper presents the first record of emergency queen rearing in stingless bees. The main steps of the event in Trigona (Frieseomelitta) varia (Lepeletier) queenless colonies are: 1) construction and provisioning of an auxiliary cell in close contact to that housing a late feeding-stage larva; 2) construction of a connection between the two cells; 3)
