Mosquito is the vector that transmits the infective larvae to the definitive host, which is typically a dog, but can also be other animals such as cats, wolves, and coyotes. The adult heartworms reside in the pulmonary arteries and right heart chambers of the definitive host, where they mate to produce microfilariae that circulate in the bloodstream and can be taken up by mosquitoes during a blood meal. Therefore, mosquitoes are the intermediate host, not the definitive host.
