Abstract | ||
The biology of malacophagous sarcophagid, Ravinia striata, was investigated at 27±2°C and R.H. 75±5% in association with feeding its larvae on the species Monacha obstructa. Under these conditions the total larval duration occupiad 7.83±0.75 days associated with 25% mortality percent. Through this stage, 16.73±2.42 snails were consumed at a daily consumption rate of 2.14±0.28 individuals. The pupal duration lasted 9.07±0.54, associated with 6.67% mortality rate. Number of tarviposition was 2.75±0.45 giving a total number of 52.58±3.75 larvae. The sex ratio was 3:4 (female : male) and the longevities of the two sexes were 55.08±2.35 and 69.0±5.37 days, respectively. | ||
