| Abstract: | Laboratory-rearedBiosteres tryoni (Cameron) reached peak ovarian maturation on the 5th and 7th days after emergence in unmated and mated ♀♀, respectively. When ♀♀ were not allowed to oviposit, contents of the oocytes
were hydrolyzed and reabsorbed. However, when hosts were available for oviposition a significant increase of egg maturation
rate was noticed.
Mean realized fecundity during the life span was 71.7±8.1 and 69.0±6.7, and mean longevity was 13.5±0.9 and 15.1±0.6 days
for mated and unmated ♀♀ respectively.
