Resumen

The effect of sublethal concentrations (30% lethal concentration [LC30] = 0.41 ppm, LC50 = 1.04 ppm, and LC70 = 2.60 ppm) of VectoBac® 12 aqueous suspension (AS, Bacillus thuringiensis var. israelensis H-14, 600 ITU/mg) on life parameters of Aedes aegypti and its F, progeny (not exposed) was assessed in laboratory tests. Based on the data, it was clear that concentrations of 0.41 ppm of VectoBac significantly shortened the duration of the developmental cycle of the exposed mosquitoes, but not that of the F1 (not exposed). Significant differences were found among the proportions of the age-specific survival between each toxic level, whereas the control did not differ from the treated individuals at the LC50 and LC70. The survival curves of the F1 showed significant differences among the different treatments and with the control. A significant effect was found on the fecundity of adults. Age-specific fecundity was markedly lower for the LC50 and LC70 treatments compared to the LC30 treatment and the control. In general, life parameters were affected inversely and significantly at higher concentrations of VectoBac, both in the exposed population of Ae. aegypti and in the F1 (not exposed).
