“…Transcription of vg was downregulated under the crowding, starvation and cold shock conditions (Table 1). The reduced expression of Vg, as an antioxidant, seems natural if it is assumed that the reduced metabolic rate is commonly resulted from these conditions due to the following respective factors (i.e., reduced labor, depleted nutrients and reduced temperature under the crowding, starvation and cold shock conditions, respectively) 52 , which results in the reduction of metabolism-related oxidative stress. Under these conditions of vg downregulation, all the hsp genes tested were also undertranscribed.…”

The honey bee acetylcholinesterase 1 (AmAChE1) has been suggested to be related to stress response as judged from its elevated expression level under brood rearing-suppressed conditions. To further investigate the involvement of AmAChE1 expression in the stress response and its physiological functions, we analyzed altered expression profiles of AmAChE1 induced by diverse stress factors. In addition, transcription profiles of several heat shock protein (Hsp) genes ( hsps ) and the vitellogenin (Vg) gene ( vg ) known as general stress markers were investigated as positive references. Among the tested stress conditions, AmAChE1 expression was induced under the brood rearing-suppressed, crowding and heat shock conditions. The hsps , particularly hsp70 and hsp90 , responded to seven of nine stress conditions tested, confirming that hsp expression profiles can serve as a general stress marker. Taken together, AmAChE1 expression is not suitable for using as a stress marker due to its limited response. Nevertheless, AmAChE1 expression appears to be connected, at least in part, to heat shock response and other pathways. Considering that AmAChE1 likely regulates the ACh titer particularly in non-neuronal tissues, thereby modulating the signal cascades mediated by mAChR, the AmAChE1 expression profile under different conditions likely provides important information on its physiological roles in honey bees.

“…That bees in a winter hive sometimes increase their metabolic rate as air temperature is lowered has long been known (Corkins and Gilbert, 1932;Simpson, 1961;Free and Simpson, 1963). However, several problems have plagued much of the data that make interpretation of possible mechanisms of thermoregulation often difficult if not impossible.…”

“…In temperate climates honeybee colonies cease to rear brood in autumn and live on their accumulated food reserves until flowers yield nectar and pollen in spring. Although individual bees are immobilised by cold at +9 or 10 ~ C and are killed in a few hours at about --3 ~ (FREE & SPEnCER-BOOTH, 1960), a colony of bees can keep its temperature considerably above its environment (GATES, 1914;WILSON & MILUM, 1927) and survive even at --40 ~ (FREE & SIMPSON, 1963).…”

Near Harpenden, Hertfordshire, brood rearing continues later into the autumn in small than in large colonies, and in colonies headed by queens of the current year than by queens of the previous year. In spring the amount of brood present increases with colony size, but there is more brood per bee in small than in large colonies. Food consumption per bee during winter decreased with increase in colony size, especially in colonies with fewer than 18,000 bees. The size of a colony in spring was related directly to its size in the previous autumn, and the proportion of bees that survived the winter was similar in large and small colonies. ZUSAMMENFASSUNG DIE WIRKUNG DER GRÖSSE VON HONIGBIENEN‐VÖLKERN AUF NAHRUNGSVERBRAUCH, BRUT UND LEBENSDAUER DER WINTERBIENEN In der Umgebung von Harnenden, Hertfordshire, erstreckt sich die Bruttätigkeit bei kleinen Völkern und bei Völkern mit diesjährigen Königinnen weiter in den Herbst hinein als bei großen und bei Völkern mit vorjährigen Königinnen. Im Frühjahr steigt der Brutanteil mit der Größe des Volkes an, jedoch haben kleine Völker mehr Brut pro Biene als große. Der Nahrungsverbrauch pro Biene nimmt im Winter mit zunehmender Größe des Volkes ab, besonders bei Völkern mit weniger als 18000 Bienen. Bezieht man die Größe des Volkes im Frühjahr direkt auf seine Größe im vergangenen Herbst, dann erweist sich das Verhältnis der überwinternden Bienen bei großen und kleinen Völkern als ähnlich.
