Abstract

This study involved the assessment of surface changes on hemocytes of Aedes aegypti black-eyed Liverpool strain in association with the melanization response against intrathoracically inoculated Dirofilaria immitis microfilariae (mff). Surface changes on hemocytes were identified using fluorescein-labeled wheat germ agglutinin (WGA). In mosquitoes eliciting a melanization response against inoculated mff, there was a 5-fold increase in the percentages of hemocytes exhibiting WGA binding compared with saline inoculated controls. Relationships of this hemocyte activation in relation to cell-mediated melanization responses of adult mosquitoes against mff are discussed.
