| Abstract | A closed colony of Lutzomyia longipalpis was established with specimens collected in the Raposa –
Serra do Sol indian reservoir, one of the main foci of visceral leishmaniasis in the State of Roraima,
Brazil. Biological observations were made on four generations of a L. longipalpis colony with emphasis
on productivity. Aspects studied were the number of laid and retained eggs, and the number of adults
(male and female) per generation. During the four generations the percentage of engorged females that
laid eggs varied from 64.2% (third generation-F3) to 90.3% (second generation-F2). The mean number
of eggs laid per female varied from 23.6 (F3) to 39.9 (first generation-F1). The maximum number of
eggs laid per female varied from 84 (F3) to 124 (F1). The mean number of retained eggs per female was
12.7 (parental generation-P and F1) to 22.1 (F2). The number of females exceeded the number of males
in all generations. However, significant difference for male/female ratio was found only for F3. Fecundity rates were between 42.1 (F3) and 58.3 (F2). From a total of 439 blood-fed females, 355 females laid
12,257 eggs that yield 5,354 adults (2,525 males and 2,829 females) in four generations. F2 presented
maximum productivity and fecundity rates. | pt_BR |
