abstract
The abundance of mosquito species in 4 locations of pig farms with different altitudes in North Sulawesi. This study has the objectives to measure the abundance of mosquito species suspected having a role as vector JE in the pig sties of the 4 different farm locations with different altitudes in North Sulawesi. The result of the research indicates that the differences in the altitudes of the pig farm locations do not affect the number and abundance of the mosquitoes caught, instead it increases availability of an ideal habitat for the breeding place of mosquitoes such as: wet rice paddies and ponds. This research also indicates that the Cx. vishnui and Cx. gelidus mosquitoes may also have roles as vector for the spread of the JE disease to the pigs. It was found that the highest abundance of Cx. vishnui was in Lemoh (24.32%), in Tara-tara (24.75%) and in Talikuran (25.90%), whereas in the Kalasey farms the highest abundance was Cx. gelidus (25%).
