THE INFLUENCE OF SUGARS AND AMINO-ACIDS ON THE BLOOD-FEEDING BEHAVIOR, OVIPOSITION AND LONGEVITY OF LABORATORY COLONY OF LUTZOMYIA-LONGIPALPIS (LUTZ AND NEIVA, 1912) (DIPTERA, PSYCHODIDAE, PHLEBOTOMINAE)

Schneider's Drosophila medium, a complex amino acid rich medium was te sted alone and with seven different sugars for some aspects of the bio logy of Lutzomyia longipalpis. Statistically significant results were obtained when sucrose was used alone, indicating that among the sugars tested, this is stilt the most suitable and practical one for the mai ntenance oft. longipalpis colonies. However the addition of Schneider' s medium to a pool of different sugars, was suggested to be related wi th the acceptance of the first and second blood meals and to longevity , these being, obviously, quite relevant aspects when transmission exp eriments are contemplated.
