Parasitic capacity, longevity and development of Trichogramma cordubensis (Hym., Trichogrammatidae) at three temperature regimes

4th International Symposium "Trichogramma and other egg-parasitoids", Cairo, Egypt, 4-7 October 1994.The effect of three differents temperatures (15, 20 and 25ºC) on lifetime parasitic capacity, longevity and development time of T. cordubensis is analysed. No significant difference was found between the total parasitism at the temperatures. However, the parasitism for the first seven days differed significantly between all the temperatures regime. Parasitism percentages achieved in the first week were 40,3% (15ºC), 67,5% (20ºC) and 75,6% (25ºC). A significant difference was also observed in the longevity and development time of T. cordubensis for all tested temperatures. The duration of development and longevity decreased as temperature increased
