In the experimental infection of B. malayi in 2 strains of A. subalbatus, 406 and Rendaiji strains, 58.2% and 63.3%, respectively, of the total number of filarial larvae were encapsulated mostly in the abdominal hemocoel 24 h after the infective blood meal. The encapsulation was also observed in the mid-gut and thorax, but with fewer larvae and with less intensity. Smaller numbers of B. pahangi larvae, 2.8% and 17.7% in 406 and Rendaiji strains, respectively, were encapsulated. The encapsulation of B. malayi larvae in the hemocoel of A. subalbatus was linked in a restricting factor in the larval migration from the hemocoel into the thorax.
