Insecticidal activity due to immune suppression by bioactive extracts of Photorhabdus temperata M1021. (A) Rate of mortality in Galleria mellonella larvae due to the intra-hemocoel injection of the EtOAc extract of P. temperata M1021, in a comparison with the EtOAc extract of E. coli DH5α used as control; (B) Phenoloxidase inhibition by EtOAc extract of P. temperata M1021 and purified compound from the extract in a comparison with EtOAc only and EtOAc extract of DH5α used as dual control. The resultant values are the averages of three replications (n = 3), each with ten larvae per repeat. The error bars represent mean ± SD of the three repeats. The different letters i.e., a and b above the error bars indicate significant differences among each other with p < 0.05 as determined by Duncan’s multiple range test (DMRT).
