Abstract: To determine the susceptibility of the females of four common mosquito species to the larvae of Dirofilaria immitis, laboratory experiments were mede in Nagasaki City. The number of microfilariae taken at the initial infective blood meal considerably differ by individual in all of the four species examined. In Aedes togoi the rate of filariae discharged in droppings of mosquitoes is the lowest and the experimental infection rate is the highest, and accordingly, this mosquito is probably the most susceptible species to the larvae of canine filaria among the four species examined. Culex pipiens pallens discharge filariae at the highest percentage, so that the experimental infection rate is not so high. In Culex tritaeniorhynchus summorosus the percentage dischage is high and the experimental infection rate is rather low. In Armigeres subalbatus the percentage discharge of filariae is rather low. However, the larvae entering the Malpighian tubes of the mosquito were all killed soon, therefore this mosqutio must be said to have no relation to the transmission of the disease.
