The Potential of Temephos as Larvacide for Malaria Vector Control in Katibung Subdistrict, South Lampung

Abstract

Lampung is one of provinces in Indonesia which still has malaria endemic areas in several subdistricts, including South Lampung District. In this subdistrict, the API recorded 0,212 in 2018 while in 2019 it decreased to 0,103. However, the potential of transmission still occurs due to the presence of extensive lagoons, swamps and puddle along the coast which support the proliferation of malaria vector in that area, one of which is Rangai Tri Tunggal Village, Katibung Subdistrict South Lampung. The purpose of this research is to find out the potential of temephos as a larvacide towards Anopheles sp. Mosquito larvae in Rangai Tri Tunggal Village, Katibung Subdistrict South Lampung District. The research used a quasi-experimental design by giving 1g/10 L of temephos to Anopheles sp. larvae at 10 breeding points of Anopheles sp. in Rangai Tri Tunggal Village, Katibung Subdistrict South Lampung started from August to September 2019. Larva density observations were carried out before and after the administration of temephos (day 21). The data analysis was administrated by using paired T-test. The result of the research showed that there is a significant difference (P<0,01) in the density of larvae before (23,8 heads/scoop) and after giving temephos (2,5 heads/scoop). The temperature at the sampling location ranged about 26-28°C with salinity 20 ppt, the types of aquatic plants are kale, mangroves, and water hyacinths and types of aquatic animals are fish, dragonflies and small snails. The conclusion is that temephos is worth to be considered as a larvacide for malaria vector control at Katibung Subdistrict South Lampung.
