oa Journal of the Entomological Society of Southern Africa - Nest structure and thermoregulation in the stingless bee Trigona (Plebeina) denoiti Vachal (Hymenoptera: Apidae)



Nests of the ground-nesting stingless bee Trigona (Plebeina) denoiti were excavated in Natal and compared with descriptionptions of nests excavated in Tanzania around 1953. A number of differences were found, among them a greater variation in the structure of the brood nest. Although the brood combs were spirally arranged, as in the Tanzanian nests, double as well as single spirals occurred and both types rotated either clockwise or anti-clockwise. The unique features of the nest architecture are discussed.
