Abstract: The mosquito-borne filarial worm, Dirofilaria immitis, is the causative agent of canine heartworm disease, in increasing major health problem of dogs in the U.S. and elsewhere. Until approximately 25 years ago this parasite was thought to be enzootic mainly in the southeastern states. Heartworm infection has apparently spread widely and in recent years has been recognized in California. An autochthonous case is described in a 4-year-old dog. Female mosquitoes Aedes sierrensis and Ae. dorsalis were allowed to feed on the infected dog, and the mosquitoes were subsequently examined. Ae. sierrensis took in 3 times as many microfilariae as Ae. dorsalis, while the parasite developed to third stage larvae in both species. Previous studies at Hopland indicate that Ae. sierrensis is an excellent host for at least one other filarial worm, Setaria yehi, the abdominal worm of deer. Improved means of diagnosis are needed before the zoonotic potential of D. immitis as a human health problem can be assessed. However, it seems likely that Ae. sierrensis, because of its feeding habits, would add to the zoonotic potential. Further, this species is a very difficult mosquito to control.
