Abstract

GOMES, Almério de Castro et al. Duration of larval and pupal development stages of Aedes albopictus in natural and artificial containers. Rev. Saúde Pública [online]. 1995, vol.29, n.1, pp. 15-19. ISSN 0034-8910.  http://dx.doi.org/10.1590/S0034-89101995000100004.

Aedes albopictus were reared in different containers: a tree hole, a bamboo stump and an auto tire. The total times from egg hatching to adult emergence were of 19.6,27.3 and 37.5 days, respectively, according to the container. The first, second and third-instar larvae presented growth periods with highly similar durations. The fourth-instar larvae was longer than the others stages. The pupation time was longer than the fourth-instar larvae growth period. The temperature of the breeding sites studied, which was of 18° C to 22° C on average, was also taken into consideration. The mortality of the immature stages was analysed and compared as between the experimental groups; it was lower in the natural containers than in the discarded tire. The average wing length of adult females emerging from tree hole was significantly larger (p < 0.05) than that of those emerging from the tire.
