Establishment, maintenance and productivity of a colony of laboratory from Lutzomyia spinicrassa Morales, Osorno-Mesa, Osorno & Hoyos, 1969 (Diptera: Psychodidae) in Colombia.

Abstract

Lutzomyia spinicrassa is a vector of Leishmaniabraziliensis. This sand fly has a broadgeographical distribution in Colombia and Venezuelaand it’s founded mainly in coffeeplantations. Methodology: Starting from 600females of L. spinicrassa captured in field alaboratory colony was established. The developmenttime from egg to adult ranged from 58 to78 days, 11 weeks in average. Population parametersof five successive generations maintainedin groups were compared with a generationreared individually. Results: The followingparameters were obtained in each experimentalcondition: net rate of reproduction (6.92 and 7females per female per generation), intrinsic rate of population increment (0.17 and 0.18 females perfemale per week) and finite rate of populationincrement (1.06 and 1.19 individuals per femaleper week). Conclusion: These data suggest thatthe colony of L. spinicrassa had a constant incrementduring the six analyzed generations.
