In this study we assessed the relationship between the laboratory and field performance of different isofemale lines of Trichogramma pretiosum Riley. In comparative assays, we used three rare mitochondrial haplotypes as genetic markers of the isofemale lines, and by introgressing these mitochondrial haplotypes into each of 15 genetically different nuclear lines, also tested the assumption that ...

Laboratory experiments were conducted to evaluate the effect of some commercially available biopesticidal formulations, such as Bacillus thuringiensis var. kurstaki (2g/l), sphaericus(2g/l), Beauveria bassiana (5g/l), Metarhizium anisopliae Lecanicillium lecanii (5g/l) on Temperature Tolerant strain Trichogramma chilonis (TTT). Two sets conducted, in first experiment, all test biopesticides spr...
