Ultrastructural and lectin-binding studies have established that the melanotic encapsulation reaction of Aedes aegypti Liverpool strain against inoculated Dirofilaria immitis microfilariae (mff) is a hemocyte-mediated reaction. Total hemocyte counts from mff-inoculated (= immune-activated), saline-inoculated, and uninoculated female A. aegypti were determined using a hemocoel perfusion technique. Total hemocyte populations in uninoculated mosquitoes were significantly larger in younger mosquitoes, but no significant change was noted as mosquitoes aged beyond 14 days. Hemocyte populations in immune-activated mosquitoes increased from 1 to 3 days postinoculation (PI) and decreased on days 4 and 5 PI. Hemocyte populations at 1 to 4 days PI were significantly elevated in mff-inoculated A. aegypti as compared with saline-inoculated controls. Saline-inoculated mosquitoes displayed little change in total hemocyte numbers from 1 to 5 days PI, and their hemocyte populations were similar to those seen in uninoculated insects of the same age. Experiments involving the inoculation of [3H]thymidine along with mff or saline alone and studies involving the administration of colchicine suggest that increased hemocyte populations in immune-activated A. aegypti are a result of mitotic division of circulating blood cells.
