Gyne production is regulated by the brood in a social bee (Bombus impatiens) [PDF]

Royal Society Open Science
Sexual production in social insects marks the peak of colony development, yet the mechanisms regulating it remain unclear. We investigated the role of brood in colony development, worker reproduction and sexual production in Bombus impatiens.

Maternal influence on the larval morphometry of the brush-clawed shore crab Hemigrapsus takanoi (Decapoda: Brachyura)

Scientia Marina, 2023
The morphology of larvae is a key factor influencing their behaviour, performance and ultimately their survival. There is evidence indicating a significant morphological variability among broods, and that this may be related to the size or conditions of

Performance evaluation of local honey bee race (Apis melifera secutellata) in the Metekel Zone of North Western Ethiopia

Veterinary Medicine and Science, 2022
Background Honeybee colonies differ in performance due to variations in their traits in terms of production, productivity and behaviour. The objective of this study was to identify and evaluate the performance of honey bee race at their geographical ...

Worker Reproduction in the Highly Polygynous Ant Crematogaster pygmaea Forel, 1904 (Hymenoptera: Formicidae)

Sociobiology, 2023
In most ant species, workers have retained functional ovaries, allowing them to potentially lay viable unfertilized eggs that develop into males. Mechanisms (ex.: queen and/or worker policing) have nevertheless evolved to control worker reproduction ...

A Comparative Study of Healthy and American Foulbrood-Infected Bee Brood (Apis mellifera L.) through the Investigation of Volatile Compounds

Agriculture, 2022
American Foulbrood (AFB) is a major endemic disease affecting the bee brood and the absence of chemical therapeutic treatments leads beekeepers to develop alternative management plans, based mainly on the prevention and accurate diagnosis of symptoms ...

EFFECT OF VITAMIN ADDITIVE AND COLONY MAN-AGEMENT ON HONEY BEE PERFORMANCE [PDF]

Arab Universities Journal of Agricultural Sciences, 2006
The effect of both beekeeping processes (compressed bees Cb and traditional beekeeping Tb) and food diets (vitamins mixed with pollen grains, pollen grains only and plain sugar syrup) on the colony build up were studied during February – April, 2004, at ...

Brood hiding test: a new bioassay for behavioral and neuroethological ant research

Sociobiology, 2014
We describe a new bioassay for behavioral and neuroethological ant research, the brood hiding test. A group of adult ants is taken out of the nest, confined together with brood and exposed to strong light. Ants may interact with brood, and, in particular,

A Preliminary Study on “Personalised Treatment” against Varroa destructor Infestations in Honey Bee (Apis mellifera) Colonies

Animals, 2023
The requirement for the protection of bee colonies against Varroa destructor invasions has been noted by many breeders and is included as an aspect of the development of beekeeping.

Contribution Concerning the Behaviour Knowledge before Natural Swarming in Honeybees (Apis mellifera carpathica, Linnaeus)

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Animal Science and Biotechnologies, 2020
In this study we followed the way in which evolves the behaviour of some honeybee families (Apis mellifera carpathica, Linnaeus), maintained in vertical beehives (modified Dadant type), in conditions of stationary bee keeping, having in view the natural ...

Brood thermoregulation effectiveness is positively linked to the amount of brood but not to the number of bees in honeybee colonies

Peer Community Journal, 2023
To ensure the optimal development of brood, a honeybee colony needs to regulate its temperature within a certain range of values (thermoregulation), regardless of environmental changes in biotic and abiotic factors.
