ABSTRACT
Adult cohorts and immature stages were kept under field conditions during the autumn and winter of three consecutive years. Survival, oviposition and development time from egg to adult were considered. The adult cohorts were studied under three experimental conditions unfed cohorts, cohorts fed with sugar solution and cohorts fed with both sugar solution and blood (chicken). Female longevity showed significant differences among the tree treatments. Females of unfed cohorts lived up to three weeks; females fed with sugar solution survived until six weeks, while those fed both with sugar and blood lived at most fourteen weeks; after the blood intake eggs were laid. In the immature stages, the highest relative mortality rates ocurred during the egg and larval stages. Total pre-adult mortality varied between 59.09 and 89.71 per cent. The development duration from egg to adult was between 43-62 days; there were no differences among results obtained for the three years.
