Relation of aphicidal activity with cuticular degradation by Beauveria bassiana SFB-205 supernatant incorporated with polyoxyethylene-(3)-isotridecyl ether.
The application of Beauveria bassiana SFB-205 supernatant incorporated with polyoxyethylene-(3)-isotridecyl ether (TDE-3) significantly reduced the population of two species of aphids including cotton aphid, Aphis gossypii, and green peach aphid, Myzus persicae, much higher in cotton aphid, compared with supernatant incorporated with Tween 80, which allows the relationship of aphicidal activity with the degradation of aphid cuticles to be determined. Overall, the degradation of the cuticles induced by the supernatant was more remarkable in conjunction with TDE-3 than Tween 80, and this phenomenon was more observable in cotton aphid through SDS-polyacrylamide gel electrophoresis, revealing high correlation with their aphicidal activities.
