“…The period of postembryonic development in honey bees includes 2 prepupal stages and 9 pupal stages (sealed or capped brood) (23,24). Emergence rates were highest between 31 and 36°C (89-100%), drastically dropped at higher and lower temperatures, and came to zero at 28 and 38°C (Table 1), largely confirming previous studies (1,5). Pupal development was shortest between 34.5 and 37°C (10-11 days), increased at lower temperatures, and went up to almost twice the normal duration at 29°C (19-22 days).…”

“…In the central brood area, fluctuations are as small as 35 Ϯ 0.5°C during the pupal period (3,4). Exposure to strong deviations from normal brood temperatures is known to result in increased mortality and morphological deficits (1,5).

Recent studies have shown that the behavioral performance of adult honey bees is influenced by the temperature experienced during pupal development. Here we explore whether there are temperature-mediated effects on the brain. We raised pupae at different constant temperatures between 29 and 37°C and performed neuroanatomical analyses of the adult brains. Analyses focused on sensory-input regions in the mushroom bodies, brain areas associated with higher-order processing such as learning and memory. Distinct synaptic complexes [microglomeruli (MG)] within the mushroom body calyces were visualized by using fluorophoreconjugated phalloidin and an antibody to synapsin. The numbers of MG were different in bees that had been raised at different temperatures, and these differences persisted after the first week of adult life. In the olfactory-input region (lip), MG numbers were highest in bees raised at the temperature normally maintained in brood cells (34.5°C) and significantly decreased in bees raised at 1°C below and above this norm. Interestingly, in the neighboring visual-input region (collar), MG numbers were less affected by temperature. We conclude that thermoregulatory control of brood rearing can generate area-and modality-specific effects on synaptic neuropils in the adult brain. We propose that resulting differences in the synaptic circuitry may affect neuronal plasticity and may underlie temperature-mediated effects on multimodal communication and learning.I n honey bee colonies, brood temperature is controlled precisely within a temperature range of 33-36°C (1, 2). In the central brood area, fluctuations are as small as 35 Ϯ 0.5°C during the pupal period (3, 4). Exposure to strong deviations from normal brood temperatures is known to result in increased mortality and morphological deficits (1, 5). Environmentally induced temperature changes within the hive are compensated by individual honey bee workers via endothermic heat production or evaporation cooling (4, 6, 7). Thermoregulation during winter is achieved also by endothermic heat production, but with lower absolute temperatures and less precision compared with brood rearing in summer (8,9). A recent study demonstrated that the temperature experienced during pupal development influences the behavioral performance of adult bees (10). Worker bees that had been raised at lower temperatures (within the range of naturally occurring temperatures) performed less well in dance communication and olfactory learning than bees raised at higher temperatures.As in other holometabolous insects, postembryonic development in honey bees includes complete larval-adult metamorphosis. In the pupa, the larval nervous system becomes completely remodeled to accommodate the development of adultspecific sensory organs and motor systems, which are associated with the extraordinary changes in behavior. The hormonal and neuronal processes underlying this remarkable plasticity have been the subject of numerous studies, most of them performed on the sphinx moth (Manduca sexta) and...

“…The pheromone, principally composed of MO, but also of ML and MLN in the earliest pupal days, is released by the queen pupa, probably throughout the different porous areas of the capped cell, to be detected by the workers. Koeniger (1978) provided evidence of a mechanical perception of the queen pupae in their cells to induce incubation by the workers. In our experiments, the empty cells were accepted longer than the controls with paraffin.…”

“…Mechanical and chemical stimuli seem to be involved in the queen brood recognition by the workers. Koeniger (1978) gave evidence of mechanical and chemical stimuli for recognition of queen pupae in their cells, and identified a compound from drone brood that elicit the clustering of bees on dummy queen cells (Koeniger & Veith 1983). Free & Winder (1983) showed that a contact surface pheromone is the prime larval recognition signal and that physical characteristics of the worker brood are of little significance.…”

Summary. Honey bee workers are able to nurse or to destroy and thus to recognize the capped queen cells containing a pupa. Fatty acid esters, especially methyl oleate, methyl palmitate and ethyl oleate were found in significant amounts on the queen pupal cuticle. Methyl oleate, the major component, along with smaller amounts of methyl linoleate and methyl linolenate, were involved in the recognition of queen cells by workers. In natural conditions of the colony, queen cells containing a paraffin pupal lure with methyl oleate were accepted 5.9 days by workers, releasing about 1.8 queen pupa equivalents during that period, when control cells (without ester) were kept only 2.1 days. Although these esters are non specific to honey bees, they are of great importance in social regulation of the honey bee colony.

“…Mechanical stimuli caused by the weight of the larva are essential for the function of the pheromone, 1,2-dioleyl-3-palmitoyl-glycerin, releasing warming behaviour (Koeniger, 1978;Koeniger andVeith, 1983, 1984). Also in ants (Brian, 1975) (Koeniger, 1978;Koeniger et Veith, 1983, 1984 (Koeniger, 1978;Koeniger und Veith, 1983Veith, , 1984 …”
