Mathematical Model and Dynamics Analysis of the Stingless Bee (Trigona sp.) in A Colony
Communication in Biomathematical Sciences, 2023 Trigona sp. is a stingless bee species that is widely distributed in tropical countries. It has castes in the colony, i.e. queen, worker, and male bee. Despite its size, Trigona sp.

Egg viability and worker policing in honey bees [PDF]
Proceedings of the National Academy of Sciences, 2004 In many species of social Hymenoptera, unmated workers can lay eggs that will produce males by parthenogenesis. Nevertheless, in queenright honey bee colonies ( Apis mellifera ), worker reproduction is low. One possible mechanism for this difference is worker policing, the removal of worker-laid eggs by other ...

Nationwide Screening for Bee Viruses in Apis mellifera Colonies in Egypt
Insects, 2023 Honey bees are essential for crop and wild plant pollination. However, many countries have reported high annual colony losses caused by multiple possible stressors.

Nutritional benefit of fungal spores for honey bee workers [PDF]
Scientific Reports, 2020 AbstractThe collection of fungal spores by honey bees,Apis mellifera, can be classified as active or passive, the latter when spores are associated with pollen, nectar or honey dew. While low quality and shortage of pollen have been raised as hypotheses for fungal spore collection, the nutritional value of fungal spores for honey bees is poorly ...

Social reversal of immunosenescence in honey bee workers [PDF]
Experimental Gerontology, 2005 A striking example of immunosenescence is seen in the honey bee (Apis mellifera) worker caste. The bees' age-associated transition from hive duties to more risky foraging activities is linked to a dramatic decline in immunity. Explicitly, it has been shown that an increase in the juvenile hormone (JH) level, which accompanies onset of foraging behavior,

Unexpected worker mating and colony-founding in a superorganism
Nature Communications, 2023 The emergence of caste-differentiated colonies, which have been defined as ‘superorganisms’, in ants, bees, and wasps represents a major transition in evolution.

Aging without functional senescence in honey bee workers [PDF]
Current Biology, 2007 Senescence can be defined demographically as an age- dependent increase in mortality risk, or functionally as a decline in performance. The relationship between the two phenomena is central for understanding the biological aging process and the implications of human lifespan extension [1 ].
