Biologia de Lutzomyia intermedia (Lutz & Neiva, 1912) e Lutzomyia longipalpis (Lutz & Neiva, 1912) (Diptera, Psychodidae) em condi??es experimentais: II. Influência de fatores ambientais no comportamento das formas imaturas e adultas

摘要

Proceeding on our studies on the biology of Lutzomyia intermedia and Lutzomyia longipalpis in closed colonies in the laboratory, we here present our observations on changes in their behavior caused by environmental conditions. L. longipaldis was easier to breed, more productive and more resistant to environmental changes; it feeds at any time of the day or night, while L. intermedia prefers to do it at sunset and at night, the preferencial time for oviposition and ecdysis of adults of both species. The immature stages of both species resisted to immersion in water for up to 1 hour and low temperature (5oC) for 1 to 6 hours.
