ABSTRACT
In both species, maintained under laboratory environmental conditions, anautogeny was comproved and all females that had free access to proteic source were fertiles. We obtained the following average values for Peckiachrysostoma 59.7 ñ 15.6 and 81.8 ñ 15.4 days of longevity in the respective cases of free access and no access to proteic source, 21.4 ñ 4.3 days of pre-larviposition period and 35.2 ñ 16.5 days of larviposition period, 5.3 ñ 1.8 larvipositions female with 7.0 ñ 1.1 days of periodicity, 35.7 ñ 6.1 larvae per larviposition leading to a total number of 183.8 ñ 69.2 viable larvae per female and 94.8% ñ 5.3% of productivity. The mean number of ovarioles per female was 56.4 ñ 9.8, resulting in a reproductive potential of 63.3%. For Adiscochaeta ingens, the obtained average values were 41.3 ñ 6.3 and 52 ñ 13.1 days of longevity in the respective cases of free access and no access to proteic source, 15.3 ñ 1.7 days of pre-larviposition period and 21.5 ñ 7.5 days of larviposition period, 3 ñ 0.7 larvipositions per female with 10.4 ñ 0.8 days of periodicity, 30.3 ñ 8.2 larvae per larviposition leading to a total number of 78.5 ñ 21.7 viable larvae per female and 90.1% ñ 16% of productivity. The mean number of ovarioles per female was 54.6 ñ 5.2, resulting in a reproductive potential of 55.5%. Within applied parameters, the values obtained for P. chrysostoma demonstrate its superior productivity in comparison with A. ingens
