Abstract
The developmental rate from oviposition to emergence of parasitoid D. rapae vary along with the change of temparature on constant relative h umidity 50 +/- 5%. The adults emerged out from mummies in 19 days at 1 5 degrees C, 16 days at 20 degrees C, 15 days at 25 degrees C and 10 d ays at 30 degrees C. The percentage of emergence is also linked with t he temperature variation. The highest emergence percentage (90.24%) no ticed at 25 degrees C and lowest at (72.50%) at 30 degrees C.
