Abstract

Abstract Dengue fever is a vector-borne disease with Aedes aegypti as the main vector. Vector controls currently depended on insecticide. Considering the negative effect of insecticide, Sterile Insect Technique (SIT) was developed. This study was conducted to evaluate the effect of gamma-ray irradiation on the productivity of male Ae. aegypti. Male pupae age less than 15 hours were irradiated with 60 Gy and 70 Gy gamma-ray. When the pupae became adult, the sterile males mated with the same age females Aedes aegypti. Observation on fecundity, hatchability, and age was carried out until the second generation. Gamma-ray irradiation with the dose of 60 Gy and 70 Gy showed different effects on fecundity, egg hatchability, the emergence of the adult, and age of Aedes aegypti compared to control. Abstrak Demam berdarah merupakan penyakit tular vektor yang sampai saat ini masih menjadi masalah kesehatan secara global. Vektor utama yang berperan pada penyebaran penyakit DBD yaitu nyamuk Aedes aegytpi. Pengendalian vektor saat ini sangat bergantung pada penggunaan insektisida. Dampak negatif penggunaan insektisida menyebabkan pengembangan pengendalian vektor yang lain diantaranya yaitu Teknik Serangga Mandul (TSM). Penelitian ini dilakukan untuk menganalisis produktivitas Ae. aegypti jantan iradiasi hingga generasi kedua. Pupa jantan umur <15 jam diradiasi sinargamma dosis 60 Gy dan 70 Gy. Setelah menjadi nyamuk jantan dewasa segeradikawinkan dengan nyamuk betina tidak iradiasi dengan umur yang sama. Pengamatan dilakukan terutama terhadap fekunditas, daya tetas, kemunculan nyamuk, dan umurnyamuk hingga generasi kedua. Iradiasi sinar gamma dosis 60 Gy dan 70 Gymenghasilkan dampak yang berbeda terhadap fekunditas, daya tetas telur, kemunculan nyamuk dan umur nyamuk bila dibandingkan dengan kontrol.

Abstract

Dengue control efforts have not provided adequate results. Therefore we need other measures like sterile in-sect Technique (SIT). This study aimed to observe the level of egg sterility and age of Aedes aegypti mosqui-toes after using SIT in Ngaliyan Semarang. The method of this research is a descriptive study with a cross-sectional design. A sample of the mosquitoes eggs are all the mosquitoes eggs on the paper trap in every house of RW2 population in Ngaliyan village. These samples are the result of the fertilization of male and female mosquitoes in nature. Data analysis using Wilcoxon sign test. The result showed that the average of egg sterility percentage in mosquitoes after using SIT indoors was 73.65% and the average of egg sterility per-centage outdoors was 69.08%. Wilcoxon test showed significant differences in average age of mosquitoes egg (p < 0.05), males pupae (p < 0.05), females pupae (p < 0.05), and adult female mosquitoes (p < 0.05), before and after SIT. It can conclude from this research that the SIT release in Ngaliyan village Semarang city could increase the level of sterility mosquito’s eggs and a decrease of the age of Ae. aegypti mosquitoes in this area.
