Effect of Introducing Larval Queen Cell Numbers and Rearing Season on Certain Developmental Features and Wet Weight of Commercially Produced Queens under Damietta Conditions (North Egypt) [PDF]

open access: yesJournal of Plant Protection and Pathology, 2021
The present studies were carried out to investigate the quantity (as % of accepted larvae, sealed queen cells and emerged queens) and quality (as weight of queen at emergence) of queen honeybees as affected by some internal environmental factors related ...

Honey bee maternal effects improve worker performance and reproductive ability in offspring

open access: yesFrontiers in Cell and Developmental Biology, 2023
Maternal effects are an evolutionary strategy used to improve offspring quality. In an example of maternal effects in honey bees (Apis mellifera), mother queens produce larger eggs in queen cells than in worker cells in order to breed better daughter ...

Honey Bee (Apis mellifera) Queen Reproductive Potential Affects Queen Mandibular Gland Pheromone Composition and Worker Retinue Response. [PDF]

open access: yesPLoS ONE, 2016
Reproductive division of labor is one of the defining traits of honey bees (Apis mellifera), with non-reproductive tasks being performed by workers while a single queen normally monopolizes reproduction.

Study of the age of grafted larvae on some morphological characteristics of queen honey bees (Apis mellifera)

open access: yesJurnal Ilmu-Ilmu Peternakan, 2021
Queen bees are castes in the colony tasked with producing eggs to survive a bee colony. The Queen is the only one tail in the colony and can produce eggs to be a prospective queen bee, worker and stud.

Honey bee retinue workers respond similarly to queens despite seasonal differences in Queen Mandibular Pheromone (QMP) signaling.

open access: yesPLoS ONE, 2023
Honey bee colonies maintain viable queens in part through communication with Queen Mandibular Pheromone (QMP), a mixture that signals the queen's presence and reproductive quality to workers.

Quality of queen bees in different ways of their production

open access: yesANIMAL SCIENCE AND FOOD TECHNOLOGY, 2021
Timely replacement of queens is one of the main zootechnical methods for maintaining the vital activity of bee families, and searching for ways to improve their quality is an urgent problem. The purpose of this study was to evaluate the effect of the method of obtaining queen bees of Apis mellifera sossimai and Apis mellifera carpatica breeds on their ...

The Effects of Co-Enzyme Q10 and Caffeine on Morphometric Characteristics of Queen Honey Bees

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2021
Honey bee queen quality is a critical factor of colony performance. Indications of such qualities can manifest themselves through morphological traits such as wet weight and thorax width.
