The Influence of Vegetation and House Index on Male Mosquitoes DHF Vector Abundance on Kawengen Sub-District

Abstract

The environmental conditions of an area can be a major risk factor for potential outbreaks of DHF. High vector population give an effect to the transmission vector-borne diseases. DHF vector population is related with vector DHF mating pattern. Adult male mosquitoes vector DHF plays an important role. Mating proportion was 1:1. Knowing density of male mosquitoes, can easily estimate the number of female mosquitoes. Conducted using observational analytics and male mosquito population surveillance approach. This study aim is to know the effect of variations in the presence of vegetation and House Index (HI) on the high abundance of mosquito populations. Using a light trap and total sampling technique to take adult mosquitoes. Results shows Kawengen, has variety of monoecious, rice field and also fruits (Musa, Mangifera, Psidium guavajava, Annona muricata), flowers (Plumeria,Hibiscus), bamboo, teak. Vegetation density in low-moderate category. Kawengen has moderate density (HI=36%). The number of trapped Aedes sp. male mosquitoes was 6.52%. Variety and density of plants give a support the abundance of male mosquitoes. As a resting and feeding place. The larvae density affects the sex ratio of mosquitoes.
