Resumo
The pathogen-carrying tiger mosquito, Aedes albopictus, has spread from theWestern Pacific
and Southeast Asia to Europe, Africa, the Middle East, North and South America, and the Caribbean.
This species of mosquito transmits arboviral infections, such as yellow fever, chikungunya, dengue,
zika, and several encephalitides. The objective of this research was to provide a radiation dose
inducing sterilization in adult male Ae. albopictus in the pupal stage. A cobalt-60 source of gamma
radiation at a dose rate of 381 Gy/h was used. The pupae were irradiated with doses of 0 (control), 20,
30, 40, 50, and 60 Gy. Each treatment had a total of five replications using 60 pupae. After irradiation,
the different phases of Ae. albopictus development (egg, larva, pupa, and adult) in the F1 generation
were observed daily. Parameters such as viability, fertility, longevity, and mortality were recorded.
The results from these studies showed that a dose of 60 Gy was necessary to sterilize 100% of the
male Ae. albopictus pupae.
