Influence of developing Brugia pahangi on spontaneous flight activity of Aedes aegypti (Diptera: Culicidae).

Autor(es): Berry W J; Rowley W A; Christensen B M

Resumo: Aedes aegypti (black-eyed Liverpool strain) mosquitoes were infected with microfilariae of Brugia pahangi to evaluate the effect of developing larvae on spontaneous flight activity. Studies using acoustic chambers showed that even low numbers of developing larvae (<10) inhibited mosquito flight activity, especially on days 8 through 10 postinfection. Parasite intensity was inversely correlated with flight activity, and mosquitoes infected with more than 20 larvae could not sustain flight after day 8. Mosquitoes infected with more than 30 larvae did not fly. Low numbers of developing larvae led to an increase in spontaneous flight activity during the first few days after infection. Developing parasites had little influence on the circadian activity patterns of Ae. aegypti
