Characterization of mosquitoes breeding site (Diptera: Culicidae) in Bogowonto lagoon ecosystem, Kulonprogo districts, Special region of Yogyakarta, Indonesia

Abstract

Characterization of mosquito breeding sites is a very important wayto cut off the mosquito’s life cycle. Bogowonto Lagoon is an ecosystem in the estuary area of the Bogowonto river. The conversion of land functions caused this place to be a source of the puddle. This study was conducted to determine the types and characteristics of mosquitoes breeding sites in the Bogowonto Lagoon ecosystem. The method used was purposive random sampling by observing the characteristics of mosquito breeding sites at three observation stations which were in the former ponds near the beach, mangrove forests, and ponds that was far from the beach. Data retrieval was done through larval samples, vegetation types, predator types and periphyton types (larval feed). The parameters observed were physical, biological and environmental parameters. The results showed that the mosquito species found were Anopheles sundaicus, Malaya sp. and Culex vishnui. The characteristics of mosquito breeding sites in the Bogowonto Lagoon ecosystem were turbid brackish water, with depth <1 meter, with a height of location between 3-9 masl. Breeding ponds had an open type of lighting, with water temperatures ranging from 30-35oC, salinity 17,58 o/oo - 21,34o/oo, pH ranges from 6,15-6,54 and DO 2.09-5,34 ppm. The ponds were overgrown with aquatic vegetation such as Cynodon dactylon and Acanthus ilicifolius grass in the middle of the waters. Periphyton types found in breeding sites were composed of functional groups of algae colonies, filamentous algae, and diatoms.
