Abstract
Mosquito collections by using light traps were carried out at 10-11 stations in Kyoto City area at intervals of about 10 days every year. Mean percent indexes calculated from the data of mosquito collections were used for comparison of the annual abundance of mosquitoes. Culex tritaeniorhynchus summorosus decreased recently and this decrease is correlated with the reduction of Japanese encephalitis patients. Wide use of 2 herbicides, CNP and nitrofen for rice plant cultivation may be 1 of the reasons for the decrease of the mosquitoes.This publication has 2 references indexed in Scilit:
