Teknik Serangga Mandul Nyamuk Culex quinquefasciatus sebagai Upaya Pengendalian Vektor Filariasis di Kota Pekalongan

Filariasis is a disease caused by infection filarial worms and transmitted by the bite of female mosquitoes. Controls of filariasis are still limited to the treatment of patients and prevent secondary infection, whereas the control of mosquitoes is not optimal yet. Sterile insect technique is a vector control method that environmentally friendly, effective, and potential. The study design is quasi-experimental design with pre-posttest control group design. The location of the research is in the Village of Padukuhan Kraton, District of North Pekalongan, Pekalongan City. Sterile insect technique can be made by irradiation of the male mosquitoes in the laboratory (BATAN) with dose (0 Gy, 60 Gy, 65 Gy, 70 Gy, 75 Gy and 80 Gy). The male mosquitoes exposed to irradiation testing sterility, survival, matting competitiveness and flight distance test. The male mosquitoes of Culex quinquefasciatus are derived from laboratory of Balai Litbang P2B2 Banjarnegara. Post-irradiation dose of 60 Gy, 65 Gy, 70 Gy, 75 Gy and 80 Gy obtained high sterility figures between 95.35%-98.53%, which means a chance to breed only 1.5-4.5%. The age of mosquitoes’ post-irradiation without matting about 35 days, the matting competitiveness with laboratory scale is almost close to normal (0.7-0.8), the matting competitiveness with field spring scale is lower than normal mosquito (0.04-0.2), mosquito flight range was only caught in the radius 100 m. The utilization of gamma irradiation to sterilizing Culex quinquefasciatus is effective at dose 70 Gy and can be done to intervention control of Culex quinquefasciatus in limited scope
