Abstract

Fifty three specimen of T. sordida which arrived at the adult stage were studied; there were 22 males and 31 females, all obtained from 110 eggs. The average time duration of life in the nymph phase was not statistically different between sexes, being 174.6 and 170.6 days respectively for mate and female. The females had a larger mean time duration of life as adults (503 days) than the males (284 days). During their adult life, 86.42% of the time corresponded to oviposition, the greater intensity of egg-laying ocurring during the first half of the period. The mean number of eggs was 570.8 and the ratio egg/day varied from 0.68 to 1.97.
