Compatibility of commercially available biopesticidal formulations with Temperature Tolerant strain of <i>Trichogramma chilonis</i> (TTT) in pre- and post-release situations in laboratory

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 sprayed egg cards prepared from Corcyra cephalonica eggs (pre-release situation) and percent parasitisation adult emergence recorded; second one, bio pesticides parasitized (post release was recorded. The results revealed that treated both are par with untreated control, hence they considered safe can be used along TTT.
