Resumo: 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.

Foram observados 53 exemplares do T. sordida que chegaram à fase alada, oriundos de 110 ovos; os machos eram em número de 22 e as fêmeas 31. Os tempos médios de duração da fase de ninfa não foram estatisticamente diferentes entre os sexos, sendo 174,6 e 170,6 dias respectivamente para machos e fêmeas. O tempo médio de vida na fase alada foi significativamente maior para as fêmeas, com 503 dias para estas e 284 para os machos. O período de oviposição correspondeu a 86,42% do tempo de fase alada das fêmeas, com a postura tendo maior intensidade na primeira metade desta fase. Cada fêmea pôs em média 570,8 ovos, variando a postura de 0,68 a 1,97 ovos por dia. Universidade de São Paulo.
