Development of the Timor filaria in Aedes togoi: preliminary observations
F Partono et al. J Parasitol. 1976 Dec.
Abstract
Developmental stages of the Timor filaria recovered from experimentally infected Aedes togoi mosquitoes are described. Mosquitoes were dissected and examined for larvae beginning 1 1/2 days and continuing daily for 9 days after they had fed on a carrier on the island of Flores, Indonesia. Timor microfilariae develop rapidly to third-stage larvae within the thoracic muscles of A. togoi: the first molt occurs at 3 1/2 days, the second molt as early as 5 1/2 days, and infective forms are found at 6 1/2 to 7 1/2 days postfeeding. These larvae were compared with similar stages of subperiodic Brugia malayi recovered from A. togoi fed on an infected jird (Meriones unguiculatus) and the features distinguishing larvae of the Timor filaria from those of B. malayi are restricted to the tails of the first-stage forms. The terminal and subterminal nuclei of the Timor larva are generally smaller than those of B. malayi, and there is little if any bulge of the cuticle around them. A constriction of the tail between these nuclei is subtle or absent. The findings of this study support the view that the Timor filaria is a member of the Brugia complex.
