PEREZ INSUETA, Omayda et al. Effects of Tapinoma melanocephalum  (Hymenoptera: Formicidae) on  Aedes aegypti (Díptera: Culicidae) eggs in an insectarium  . Rev Cubana Med Trop [online]. 2004, vol.56, n.3, pp. 167-171. ISSN 1561-3054.

The action of Tapinoma melanocephalum, an ant species causing damages to agriculture, on Aedes (Stegomyia) aegypti eggs was evaluated for the first time in Cuba at an insectarium of Medical Entomology in the breeding colonies and the storage place. The ants colony came from a studied natural population established inside the insectarium. Eggs belonged to two different oviposition times: (a) laid within the previous 24 h. and (b) stored in the lab for 8 months. The results obtained showed a higher predation of T. melanocephalum over the newly laid Aedes aegypti eggs (Z=9.1; p <0.0001). The predating action of Tapinoma melanocephalum on Aedes aegypti eggs should be considered in the colonization of this mosquito.
