Bionomic aspects of Pattonella intermutans (Thomson, 1869) (Diptera, Sarcophagidae) under laboratory conditions

Abstract

Life and fertility tables of Pattonella intermutans (Thomson, 1869) were studied in the laboratory conditions. The flies colonies were maintained at 20-28°C, 80±10% RH and observed daily. Life expectancy was 2.34 weeks for males and 2.33 weeks for females. The survivorship curves presented a type II tendency for females and type III for males. The periods of pre-larviposition and larviposition were of 2.5 and 9.5 weeks, respectively. Using data of the life table of fertility, the following values were obtained: Ro=24.83 times; T= 5.06 weeks; r=0.64 and lambda=1.89. The number of generations of P. intermutans was estimated to be 10.28 generations/year. The females had a high fertility under laboratory contiditions.
