Weight Changes by the Queen Honey Bee During Swarming

Annals of the Entomological Society of America, 1966
Mated, laying queen honey bees, Apis mellifera L., lose approximately ⅓ of their weight during the process of swarming. Weight loss starts when they lay eggs in queen cups, and is maximal when the new queen cups are capped. The queens regain weight after swarming, and are usually normal within 5 days. Shaking of the queens is apparently not required to

Live Weight of Queen Honey Bees (Apis Mellifera L.) Predicts Reproductive Characteristics

Journal of the Kansas Entomological Society, 2008
ABSTRACT: The study was conducted to determine the effects of queen body weight at emergence on the mating ratio, acceptance of the mated queens by the queenless colonies, onset of oviposition, diameter of spermathecae, the number of spermatozoa in the spermathecae, and the egg-laying rate of the queens.

Effects of Honeybee Queen Weight and Air Temperature on the Initiation of Oviposition

Journal of Apicultural Research, 1987
SummaryThe onset of oviposition of 1396 queens reared in two years in the Peace River region of Alberta, Canada, ranged from 4 to 22 days after emergence, with a mean of 10·6 ± 0·1 days. There was evidence to suggest that some queens may start to lay eggs within 24 h after mating.

Honey Productivity of Honeybee Colonies in Relation to Body Weight, Attractiveness and Fecundity of the Queen

Journal of Apicultural Research, 1983
SummaryThe relationship between queen weight, queen attractiveness, sealed brood area, and colony honey production were investigated. Queens' attractiveness to workers varied greatly, but was not correlated with any of the other measured parameters. Queen weight, 18 hours after removal from mating nuclei, averaged 214·4 mg and decreased to 207·9 mg ...

The Effect of Short-Term Storage Methods on the Weight of Queen Honeybees

Journal of Apicultural Research, 1987
SummaryIn each of two years' queen honeybees (Apis mellifera L.) imported from California were stored using one of three methods: (1) a four-frame queenless nucleus hive (NH), (2) a strong two-chamber queenless queenbank (QB) or (3) a temperature-controlled incubator (IN).

The best of heavy queens: influence of post-flight weight on queens’ survival and productivity in Acromyrmex subterraneus (Forel, 1893) (Hymenoptera: Formicidae)

Insectes Sociaux, 2020
The weight of post-flight ant queens reflects how much stored resources are available to overpass the new colony foundation phase. Acromyrmex queens must dig the nest and forage during this period to cultivate the symbiotic fungus for larvae feeding, implying even higher energetic costs.

Relation of Body Weight to Fecundity in Queen Honeybees

The Canadian Entomologist, 1960
In a recent communication, Hoopingarner and Farrar (1959) report that the weight of the queen honeybee is genetically controlled, and that a proportional relationship exists between body weight and the number of ovarian tubules. These statements corroborate the findings by Eckert (1934) who found that the number of ovarioles tends to be influenced by ...

Effect of Confinement on the Weight of Honeybee Queens

Journal of Apicultural Research, 1975
SummaryThirteen newly emerged queen honeybees were caged for 15 hours, with candy, at 34°C and 60% RH. Their weight at emergence was significantly correlated with their weights after 3, 6, 9, 12 and 15 hours, but less significantly correlated with their weights during egg laying and some time after its cessation.

Influence of queen weight and colony origin on worker response in Solenopsis geminata

Physiological Entomology, 2004
Abstract. The influence of weight and colony origin of the queen of Solenopsis geminata (F.) (Hymenoptera: Formicidae) on worker attraction is studied under laboratory conditions.

Seasonal Comparison of Weight, Energy Reserve, and Nitrogen Changes in Queens of the Baldfaced Hornet (Hymenoptera: Vespidae)

Environmental Entomology, 1992
Queens of Dolichovespula maculata (L.) were collected before the hibernation period in the fall, before and shortly after nest initiation in the spring, and after colonies had produced more than two worker broods. Fresh and dry weights were determined for all queens, and a seasonal comparison of the energy reserves of lipids, sugar, and glycogen was ...
