Summary
Observations showed that the mosquito,Aedes fitchii (Felt andYoung), readily feeds on mink. Injection of homogenized mosquitoes, held for various periods after an infectious blood meal, into susceptible mink revealed that this mosquito retained Aleutian disease (AD) virus for 35 days. The virus in groundA. fitchii was titrated immediately and 15 days after infective feeding. The titer decreased from 104ID50/ml to 102ID50/ml during this time. Conversely, AD virus did not persist for six days inAedes aegypti (Linnaeus). Homogenized pools of heads combined with salivary glands ofA. fitchii 5, 10, and 15 days after infective feeding were injected into susceptible mink, viral infectivity was demonstrated in this region at 10 and 15 days after infective feeding but not at 5 days. This study suggests that replication of AD virus may occur inA. fitchii and a true vectorpathogen relationship exists between AD virus and certain arthropods.
