Gyne and drone production in bombus atratus (Hymenoptera: Apidae) [PDF]
, 2017 For over a decade, our research group has studied the biology of the native bumblebee, Bombus atratus, to investigate the feasibility of using it to pollinate crops such as tomato, strawberry, blackberry and peppers.

Journal of Basic and Applied Zoology, 2021 Background There is one queen in each honey bee, Apis mellifera L., colony under normal conditions. This queen performs egg laying and pheromonal control in the colony. All genetic characteristics of bee workers and drones depend on the queen.

Killing and replacing queen-laid eggs: low cost of worker policing in the honey bee [PDF]
, 2014 Worker honeybees, Apis mellifera, police each other’s reproduction by killing worker-laid eggs. Previous experiments demonstrated that worker policing is effective, killing most (∼98%) worker-laid eggs. However, many queen-laid eggs were also killed (∼50%

Infection and transmission of Nosema bombi in Bombus terrestris colonies and its effect on hibernation, mating and colony founding [PDF]
, 2008 The impact of the microsporidium Nosema bombi on Bombus terrestris was studied by recording mating, hibernation success, protein titre in haemolymph, weight change during hibernation, and colony founding of queens that were inoculated with N.

Journal of Apicultural Science, 2018 This study aims to investigate the effect of queen cell size (9.4 mm, 9.6 mm, 9.8 mm and 10.0 mm) and mother queen caged time (0 day, 2 days and 4 days) on rearing young queens without grafting larvae.

Sex investment ratios in eusocial Hymenoptera support inclusive fitness theory [PDF]
, 2015 Inclusive fitness theory predicts that sex investment ratios in eusocial Hymenoptera are a function of the relatedness asymmetry (relative relatedness to females and males) of the individuals controlling sex allocation. In monogynous ants (with one queen

Influence of queen mothers on the honeybee hive varroa mite population in the year 1998
Acta Agriculturae Slovenica, 1999 Varroa mite population was studied in 317 hives located in 40 apiaries in July 1998. Queens originated from 46 mother queens were reared at 16 different rearing locations in Slovenia.

Italian Journal of Animal Science, 2022 Rearing techniques are important to determine a successful honey bee production. Queen cell cup size may affect the acceptance rate of grafted larvae and queen’s size, which in turn may influence the quality of the colonies.
