This stage investigate the bacterial pathogenicity of cooperative bacteria against the serious bug pest that feeds voraciously on two together agricultural and horticultural crops, Spodoptera litura.Spodoptera litura Fabricius (Lepidoptera: Noctuidae) an economically main insect contagions worldwide, especially in the jungles, temperate zones, and added warm environments. In this investigation cooperative bacteria of entomopathogenic nematodes were judged for their insecticidal activity against larvae of S. litura under testing room conditions. The four new isolates (EPB1, EPB4, EPB8 and EPB9) belongs to Photorhabdus luminescence unique from nematode Heterorhabditis bacteriophora and one disconnect (EPB3) of Xenorhabdus nematophila isolated from nematode Steinernema sp. were used in the study. The undamaged cell delay and cell-free extract were screened for their bacterial pathogenicity and the results granted mortality of larvae afterwards 24h of post treatment. The portion mortality treated accompanying intact container suspension was significantly bigger CFU with a middle lethal time grazing from 33-45h. The results showed that the isolates EPB3 (Xenorhabdus nematophilus) is relatively more virulent than other Photorhabdus isolates against the test bug S. litura. This study paves the way for advances in our understanding of the resentment of several Entamopathogenic microorganisms in non- model insects, such as the new obtrusive S. frugiperda species in Africa.These cooperative bacteria can also be caused as potential biopesticides against insect plague by screening them for their biocontrol influence in greenhouse and field backgrounds.
