The year of the honey bee (Apis mellifera L.) with respect to its physiology and immunity: A search for biochemical markers of longevity
(2019-08-01)
It has been known for many years that in temperate climates the European honey bee, Apis mellifera, exists in the form of two distinct populations within the year, short-living summer bees and long-living winter bees. ...
Comparative study of the hygienic behavior of Carniolan and Africanized honey bees directed towards grouped versus isolated dead brood cells
(FUNPEC-EDITORA, 2009)
In Apis mellifera, hygienic behavior involves recognition and removal of sick, damaged or dead brood from capped cells. We investigated whether bees react in the same way to grouped versus isolated damaged capped brood ...
Defense Response in Brazilian Honey Bees (Apis mellifera scutellata × spp.) Is Underpinned by Complex Patterns of Admixture
(2020-08-01)
In 1957, an invasive and highly defensive honey bee began to spread across Brazil. In the previous year, Brazilian researchers hoped to produce a subtropical-adapted honey bee by crossing local commercial honey bees (of ...
Is the number of antennal plate organs (sensilla placodea) greater in hygienic than in non-hygienic Africanized honey bees?
(2003-12-01)
Hygienic behavior is a desirable trait in honey bees (Apis mellifera L.), as hygienic bees quickly remove diseased brood, intermpting the infectious cycle. Hygienic lines of honey bees appear to be more sensitive to the ...

Composition of Stingless Bee Honey: Setting Quality Standards
(Interciencia Association, 2020)
Honey from Tiúba stingless bees (Melipona fasciculata) produced in different ecosystems: physical and sensory studies
(2020-07-01)
BACKGROUND: Honey from Tiúba stingless bees (Melipona fasciculata) produced in three different ecosystems in Brazil (Cerrado, Litoral and Baixada), as well as a sample of honey from Apis mellifera bees from the Baixada ...
Exposure to thiamethoxam during the larval phase affects synapsin levels in the brain of the honey bee
(2019-03-01)
Thiamethoxam (TMX) is a neurotoxic insecticide widely used for insect pest control. TMX and other neonicotinoids are reported to be potential causes of honey bee decline. Due to its systematic action, TMX may be recovered ...
