“…In 1-year-old queens, T1-44 has been reported to be the largest glomerulus in the antennal lobe neuropil (Arnold et al, 1988). Although this is true also of most young worker bees, our results show that in foragers the volume of glomerulus T1-44 is often exceeded by that of T4-3(1).…”

“…Differences between the contribution of glomerulus T1-44 to the total volume of the antennal lobe neuropil of queen and worker honey bees has been used as an example of female caste dimorphism in the structure of the antennal lobes of the brain (Masson and Mustaparta, 1990). Although T1-44 does contribute more to the total volume of the antennal lobe neuropil in 8-day-old queens (1.3%; Arnold et al, 1988) than in 18-21-day-old workers (1.1%; Arnold et al, 1985) or foragers (1.2%; present investigation), its contribution in 6-and 10-day-old workers, nurses, and comb builders is the same (1.3%; present investigation) as that reported in 8-day-old queens. In 1-year-old queens, T1-44 reportedly contributes 1.468 to the total volume of the antennal lobe neuropil (Arnold et al, 1988).…”

Although this value exceeds any recorded in the present investigation for young worker bees, our results suggest that such differences may reflect the age and behavioural activities of the bee rather than a caste-specific difference in antennal lobe morphology.…”

Structural plasticity of identified glomeruli in the antennal lobes of the adult worker honey bee

1996

Adult worker honey bees alter their behaviour with age but retain a strong reliance on sensory information from the antennae. The antennae house a diverse array of receptors, including mechanoreceptors, hygroreceptors, olfactory receptors, and contact chemoreceptors, which relay information to the brain. Antennal sensory neurons that project to the antennal lobes of the brain converge onto second-order interneurones to form discrete spheres of neuropil, called glomeruli. The spatial organisation of glomeruli in the antennal lobes of the honey bee is constant, but the central distribution of information from receptors tuned to different sensory modalities is unknown. Here we show that the glomerular neuropil of the antennal lobes undergoes constant modification during the lifetime of the adult worker bee. Changes in morphology are site specific and highly predictable. The total volume of the glomerular neuropil of the antennal lobe increased significantly during the first 4 days of adult life. Each of the five readily identifiable glomeruli examined in this study exhibited a unique pattern of growth. The growth of two of the five glomeruli changed dramatically with the shift to foraging duties. Furthermore, significant differences were identified between the antennal lobes of bees performing nectar- and pollen-foraging tasks. The highly compartmentalized nature of the antennal lobes, the ease with which specific glomeruli can be identified, and the predictability of changes to the antennal lobe neuropil make this an ideal system for examining the mechanisms and behavioural consequences of structural plasticity in primary sensory centres of the brain.

“…While detailed consideration of this issue lies beyond the scope of the current review, it is interesting to note that female pheromone autodetection has been documented in some moth species (Ochieng et al 1995;Schneider et al 1998). Intriguingly, ALs of queen bees contain a glomerulus of larger size, which could be a female macroglomerulus (Arnold et al 1988). Future studies will reveal whether this large glomerulus is dedicated to processing the queen's own pheromone and/or some other species-specific signal.…”

Queen mandibular pheromone: questions that remain to be resolved

-The discovery of 'queen substance', and the subsequent identification and synthesis of key components of queen mandibular pheromone, has been of significant importance to beekeepers and to the beekeeping industry. Fifty years on, there is greater appreciation of the importance and complexity of queen pheromones, but many mysteries remain about the mechanisms through which pheromones operate. The discovery of sex pheromone communication in moths occurred within the same time period, but in this case, intense pressure to find better means of pest management resulted in a remarkable focusing of research activity on understanding pheromone detection mechanisms and the central processing of pheromone signals in the moth. We can benefit from this work and here, studies on moths are used to highlight some of the gaps in our knowledge of pheromone communication in bees. A better understanding of pheromone communication in honey bees promises improved strategies for the successful management of these extraordinary animals.queen mandibular pheromone / Apis mellifera / olfactory system / biogenic amines / juvenile hormone / ecdysteroids

“…In den letzten fünf Jahren sind nach bis dahin eher sporadischen Untersuchungen (Lacher, 1964;Vareschi 1971;Pareto, 1972;Suzuki, 1975;Homberg, 1984) mehrere detaillierte anatomische und physiologische Analysen des Antennallobus durchgeführt worden (Arnold et al, 1985;Arnold et al, 1988;Flanagan und (Akers und Getz, 1992;Lieke, 1992) (Vareschi, 1971, Boeckh und Ernst, 1987 (Vareschi, 1971) (Boeckh et al, 1990 (Fonta et al, 1991 (Getz et al, 1986;Getz und Smith, 1987;Brückner und Getz, 1991 (Menzel et al, 1991;Hammer, 1992 (Akers and Getz, 1992). There seems to be no distinct receptor cell classes with different odor spectra as previous research had indicated (Vareschi, 1971).…”
