“…This may be because we studied small colonies with relatively few drones. The times we recorded are about 90 min earlier than recorded for A. cerana in Sri Lanka (Koeniger and Wijayagunesekera, 1976), about 1 hour earlier than those recorded in Thailand (Rinderer et al, 1993), very similar to those recorded on the Malay peninsular , later than those in Sulawesi (Hadisoesilo and Otis, 1996), and within the range for those recorded in Japan (Yoshida et al, 1994).…”

Evidence for reproductive isolation between two colour morphs of cavity nesting honey bees (Apis) in south India

In south India there are two distinct colour morphs of cavity nesting honey bees: the yellow Plain morph and the black Hill morph which are collectively known as Apis cerana. We show that the Hill morph is associated with a widely distributed mitochondrial haplotype that is present throughout mainland populations of south east Asian A. cerana. In contrast, the Plain morph, which is apparently confined to low to moderate elevations in India and Sri Lanka, is associated with a unique mitochondrial haplotype that is not present in other cavity nesting honey bees. We further show that in a region of sympatry (Bangalore, Karnataka State) the drone mating flight times of the two colour morphs barely overlap. Combined, drone flight data and the complete separation of mitochondrial haplotypes suggest that the two morphs are reproductively isolated. The Plain morph is distinguished from the Hill morph by the first three abdominal tergites of the worker, which are completely yellow in the Plain morph, whereas in the Hill morph they are black or black with yellow patches. Although the two morphs are generally distinguishable in the field by overall colouration, microscopic examination of the first 3 abdominal tergites is preferred.

“…1) seems to be related to the earlier onset of flight. Drones begin mating flights around 7 days after emergence (Mindt, 1962;Yoshida et al, 1994;Tozetto et al, 1997). Workers begin sporadic orientation flights around 8 days after emergence but real foraging flights usually begin from about 14 days after emergence (Winston, 1987).…”

The learning ability of the European honeybee, Apis mellifera, is well known. However, in a proboscis-extension reflex (PER) assay, newly emerged and very young worker bees could not associate a given odor (conditioned stimulus, CS) with a sucrose reward (unconditioned stimulus, US): This ability was acquired 5 to 9 days after emergence in workers, while it was accomplished 2 to 5 days after emergence in drones, probably reflecting the earlier onset of flight in drones. When workers are reared individually in a confined condition deprived of colony odor and other social stimuli, they do not develop the ability even after 9 days after emergence. In a series of experiments subjecting the bees to the confined condition for various lengths and timings, the important period for acquiring the learning ability was from day 2 to 6 after emergence. However, even bees that acquired the ability lost it when exposed to the confined (stimuli-deprived) condition for the next 15 days, meaning that the continuous input of appropriate sensory stimuli is essential for both acquiring and maintaining the learning capability.
