Abstract

The life cycle of Lutzomyia shannoni (Dyar), was described for
laboratory conditions with maximum daily temperatures of 27-30 C, minimum
daily temperatures of 22-27 C and relative humidity between 87-99 %. Life
cycle in each stage was as follows: egg 6-12 days (ave. 8.5 days); first
stage larva 5-13 days (ave. 9.6 days); second stage larva 4-13 days (ave.
9.2 days ); third stage larva 5-19 days (ave. 11.8 days); fourth stage
larva 7-37 days (ave. 19.9 days); pupa 7-32 days (ave. 15.2 days). The life
expectancy of adults ranged from 4 to 15 days (ave. 8.6 days). The entire
egg to adult period ranged from 36 to 74 days (ave. 54.6 days). On average,
each female oviposited 22.7 eggs; the average egg retention per female was
24.3 eggs.
