Summary:The efficacy of entomopathogenic fungi [Beavueria bassiana (Bb08, Bb10) and Isaria fumosorosea (Ifr)] isolated from different regions of Southern Tamil Nadu, India was assessed against red cotton stainer, Dysdercus cingulatus. All the tested isolates showed 100% mortality. The B. bassiana isolates such as Bb08, Bb10 and an I. fumosorosea isolates exemplified the significant mortality among the isolates tested. LC^sub 50^, LC^sub 90^ and correlation coefficient were calculated for mortality. Bb08, Bb10 and Ifr isolates unveiled the lowest LC50 (5.9 x 10^sup 5^, 6.6 x 10^sup 5^ and 2.6 x 10^sup 5^) and LC^sub 90^ (1 x 10^sup 9^, 7.3 x 10^sup 8^ and 3.9 x 10^sup 8^) value compared to the isolates tested. Highly significant correlation co-efficient was observed in the isolates Bb08, Bb10 and Ifr [PUBLICATION ABSTRACT]
