摘要

Caste-specific behaviours among social insects are known to be largely influenced by olfactory cues. The present study addresses the question whether individual castes (queen, major and minor) of the weaver ant, Oecophylla smaragdina (Fabricius) differ in the organization of the chemosensory structures on the antenna, maxillary and labial palps. The sensory structures were studied by light and scanning electron microscopy. It was observed that the sensilla numbers differ among the three castes, whereas all the three castes possess similar types of chemosensilla. This variation may be a factor underlying the differential chemosensory ability of castes. As the number of sensilla differs among castes, it is likely that a differential development of castes in terms of the number of primary mother cells, which are precursors of chemosensory structures, causes the variation of sensilla numbers. This mechanism appears to be a common principle in the caste-specific sensory system development as the visual system of honey bee has also been shown to follow such a mechanism.
