Abstract:Twenty-eight highly virulent strains of symbiotic bacteria were isolated from 28 entomopathogenic nematodes in the soil samples collected from different regions of China.The crude toxins were extracted from the 28 symbiotic bacteria strains.Bioassay results showed that all crude extracts had virulent activity to the first instara of Plutella xylostella and Laphygma exigua to some extent,among which 5-5B strain was the best one.The average corrected mortalities to P.xylostella and L.exigua were 100 % and 68....
