Trichogrammatidae) have been successfully utilized for biocontrol of several Lepidopteran pests worldwide. Because of their low host specificity Trichogramma can be mass reared more easily in large numbers and on different natural and factitious hosts. Life table parameters were assessed for Trichogramma cacoeciae Marchall, T. evanescens Westwood and T. brassicae Bezdenko on Ephestia kuehniella Zeller and Cadra cautella Walker at three temperatures (20, 25 and 30 degrees C) as the potential factitious hosts for mass rearing. Female longevity ranged between 9.77 and 2.56 days in our experiments. Fecundity ranged from 73 to 91 parasitized eggs in C. cautella and 76-109 parasitized eggs in E. kuehniella. T. brassicae exhibit similar values of the intrinsic rate of increase ratio (r(m)) 0.5407 and 0.5478; the finite rates of increase (lambda) were 1.717 and 1.7295 and the doubling times 1.28 and 1.26 at 25 and 30 degrees C, respectively, in C. cautella. The mean duration of one generation (T) varied between 8.25 and 13.37 days for T. cacoeciae, 8.14 and 13.47 days for T. brassicae and 8.23 and 13.18 days for T. evanescens in C. cautella. Generation times for T. cacoeciae varied between 8.23 and 14.68 days, 8.28 and 14.37 days for T. brassicae, and 7.74 and 14.58 days for T. evanescens in E. kuehniella eggs. Both species (T. cacoeciae, T. brassicae) had the same intrinsic rate of increase (r(m); 0.5700 and 0.5704), finite rate of increase (lambda; 1.7682, 1.7691) and doubling time (Dt, 1.21) at 30 degrees C in E. kuehniella, respectively.en10.1080/09583150903497880info:eu-repo/semantics/closedAccessegg parasitoidsmass rearinglongevityfecunditylife tableintrinsic rate of increaseSpecies HymenopteraSouth-CarolinaFertilityPretiosumQualityEggsBehaviorMaizeMothLepReview Article203245255Q3WOS:0002734770000022-s2.0-74349098579Q2
