Abstract
The research was conducted to study the efects of Beauveria bassiana (the chines isolte B.C.) and Trichoderma harzianum in concentration of 3x107 Spore ml of each one )on the Brown babanded cockroach, Supella longipalpa ( Dictyoptera :Blattidae ) . The resalt showed that the adult mortality which casued by B. bassiana when it used as baiting with wheat bran it about 86.67% with high significant . while the less percent 36.67% was obtained when the suspension of T. harzianum was used ,with high significant difference with control treatment which has no adults mortality . The study also explained that B. bassiana reduced the hatching rate of eggs to 56.66% copared with control which was 93.33% . The exudates of fangi significanty increased the adults mortality rate . high concentration (100%) of B. bassiana exudates increased the adult mortality rate to100% and the low concentration ( 25% ) of T. harzianum led to increase the ratio to 40% , whil the control treatment has no mortality .
