abstract
Aedes albopictus is an essential vector of dengue hemorrhagic fever (DHF) in the world. Currently, DHF vector control in Indonesia is still using chemical insecticide. However, chemical insecticide caused problems to human health, environment, and triggered the emergence of resistant Ae. albopictus colony. Sterile Insect Technique (SIT) has been developed for Ae. albopictus vector control. This study aimed to analyze the different effect doses of gamma-ray irradiation on Ae. albopictus and its offsprings. The research was held from October 2017 to January 2018 in the National Nuclear Energy Agency of Indonesia (BATAN), Jakarta. The design of this study was a true experiment. The treatment was irradiation of male Ae. albopictus pupae with five doses of gamma ray (30 Gy, 40 Gy, 50 Gy, 60 Gy, and 70 Gy). Irradiated Ae. albopictus male was immediately mass mated with the same aged normal females, and measured fecundity and eggs hatchability and its offspring. The results showed that irradiated of gamma-ray with doses of 50, 60, 70 Gy decreased fecundity in Parental and F1 of Ae. albopictus. Eggs produced by Ae. albopictus female which were mated with an irradiated male at doses of 60 and 70 Gy in Parental, was not hatched. Meanwhile, unhatched eggs occurred in F1 from an irradiated male at doses of 30, 40 and 50 Gy.
