Pengaruh Aplikasi Teknik Serangga Mandul (TSM) terhadap Sterilitas Telur dan Penurunan Populasi Vektor Demam Berdarah Aedes aegypti di Daerah Sub Urban Endemis DBD di Salatiga
Sterile Insect Technique (SIT) is a vector control method which is safe to the environment and directed to specific target. The vector resistance against insecticide encourage the application of SIT in an effort to reduce the mosquito populations. Indicators and parameters of the population can be determined by the percentage of eggs sterility. Sterile egg is that does not contain embryo and usually called barren egg and does not hatch.
The aim of the study was to determine the effect of SIT on increasing percentage eggs sterility followed by reducing Aedes aegypti population. The Study had been carried out in the residential area of Salatiga in 2012, Central Java. Males Ae. aegypti were irradiated using cobalt-60 gamma ray (70 Gy) and was done in BATAN Jakarta. Sterile male Ae.aegypti were released five times, once a week. A number of 45 Ae.aegypti sterile males were released in each target house. Parameters measured were percentage of eggs sterile before and after aplication of sterile male, and reducing Ae.aegypti population.
The results showed the percentage of sterile eggs produced outdoor after the release of sterile males from the first, second, third, fourth, and fifth were, 72.15%, 49.55%, 87.69%, 61.93%, and 50.89%. The sterile of the indoor eggs after the release of sterile males from the first, second, third, fourth, and fifth, were 67.53%, 100%, 72.36%, 57.93%, and 94.05%. The release of sterile males five times has affected the populations of Ae. aegypti outdoor and indoor reduced to to 89.25% and 49.21%.
