ABSTRACTCulex quinquefasciatus is the main vector of lymphatic filariasis in Pekalongan City. Sterile Insect Tehnique (SIT) could be complementary vector control for filariasis. The key success of the technique depend on the ability of laboratory-reared sterile males with the wild-type females.The aim of the research was to determine the mating competitiveness, the fecundity and the fertility of sterile male Culex quinquefasciatus. The pupae of Cx. quinquefasciatus were gamma irradiated at the doses of 60Gy, 70Gy, and 80Gy, while unirradiated pupae were prepared as control. The mosquitoes emerging from the irradiated pupae could mate with a normal female in the cages. It were observed for the mean female laying eggs, the fecundity, the fertility and the mating competitiveness. The data were analyzed by one way ANOVA. The result showed that the irradiated Cx. quinquefasciatus at the doses tested did not affect on the fecundity and the mating competitiveness, but the fertility was disturbed (sterile). A dose of 70 Gy was the optimum dose or a fertility rate of 1.8% (98.2% sterile), and the value of competitiveness (C index) was 0.568. Based on the result, the irradiated Cx. quinquefasciatus can be recommended for semifield application.

First Time

Drosophila suzukii (Diptera, Drosophilidae) is an exotic species, endemic to Asia and currently a pest to small and stone fruits in several countries of North America and Europe. It was detected in 2013 for the first time in South America, in the south of Brazil. Unlike most drosophilids, this species deserves special attention, because the females are capable of oviposit inside healthy fruits, rendering their sale and export prohibited. Despite the confirmed existence of this species in different states of Brazil, this insect is yet been to be given the pest status. Nevertheless, the mere presence of this species is enough to cause concern to producers of small fruits and to justify further investigation for it’s control, especially chemical control for a possible change in status. Therefore, the goal of this work was to evaluate, in laboratory, mortality of D. suzukii adults and ovicidal effect when exposed to different insecticides registered for species of the Tephritidae and Agromyzidae families in different cultures. The insecticides deltamethrin, dimethoate, spinosad, fenitrothion, phosmet, malathion, methidathion, and zeta-cypermethrin resulted in mortality to 100 % of the subjects three days after the treatment (DAT). Regarding the effects over eggs, it was  established that the insecticides fenitrothion, malathion, and methidathion deemed 100 % of the eggs not viable, followed by phosmet and diflubenzuron, which also caused elevated reduction in the eclosion of larvae two DAT.
