“…Body mass is related to several factors including fat content (Alford, 1969a;Holm, 1972). During hibernation queens use most of the reserves (fat and glycogen) they have accumulated previously in the fat body.…”

Summary — The effects of two kinds of stored pollen (fresh and dried, kept in the freezer) on individuals and colonies of Bombus terrestris were investigated. The pattern of colony development, and the number and biomass of workers and males were similar for colonies fed on fresh-frozen pollen (FFP) and dried-frozen pollen (DFP). However, queens reared on DFP were smaller, had lower biomass, higher mortality and produced smaller colonies than queens reared on FFP.

-Considerable interspecific diversity exists among bees in the rendezvous sites where males search for females and in the behaviours employed by males in their efforts to secure matings. I present an evolutionary framework in which to interpret this variation, and highlight the importance for the framework of (i) the distribution of receptive (typically immediate post-emergence) females, which ordinarily translates into the distribution of nests, and (ii) the density of competing males. Other than the highly polyandrous honey bees (Apis), most female bees are thought to be monandrous, though genetic data with which to support this view are generally lacking. Given the opportunity, male bees are typically polygamous. I highlight intraspecific diversity in rendezvous site, male behaviour and mating system, which is in part predicted from the conceptual framework. Finally, I suggest that inbreeding may be far more widespread among bees than has hitherto been considered the case.Apoidea / rendezvous site / scramble competition / territoriality / inbreeding

“…With the goal of inducing diapause break, several researchers have attempted to first induce the hibernation of bumblebee queens under controlled conditions, despite the lengthy ovarian diapause of bumblebees (Horber, 1961;Alford, 1969aAlford, , 1975 previously described by Yoon et al (2004a). The oxygen uptake of B. ignitus queens was measured in a volumetric system with an O 2 Uptester (Daiyo Scientific Industrial Co., Tokyo, Japan).…”

Under natural conditions, the duration of the hibernation period ranges from 6 to 9 months (Alford, 1969a).

Bumblebees are widely used to pollinate various greenhouse crops. Among the different bumblebee species, Bombus ignitus is indigenous to Korea, China, Japan and Russia. B. ignitus undergoes one generation per year, and artificial hibernation is essential for year-round rearing of the bumblebee. Keeping the queens under low-temperature conditions for several months is an effective method for terminating their diapause and promoting colony development. In the present study, we investigated how cold temperature affects the artificial hibernation of B. ignitus queens. Under chilling temperatures of -2.5°C, 0°C, 2.5°C and 5°C with constant humidity >80%, the queens stored at 2.5°C exhibited the highest survival rates, which were 74.0% at one month, 67.0% at two months, 60.0% at three months, 46.0% at 4 months, 33.0% at 5 months and 24.0% at 6 months. Lower survival rates were observed at 0°C, 5°C, 7.5°C and 12.5°C. At 2.5°C the colony developmental characteristics after diapause were 1.2-to 1.5-fold greater than those when queens were stored at 5°C. Thus, 2.5°C and 70% R.H.were the most favorable chilling temperature and humidity conditions for terminating the diapause of B. ignitus queens. Introduction AbstractInt.
