Biological control of lepidopterous insect pests, Agrotis segetum, Artogeia rapae, Mamestra brassicae, Plutella xylostella, Spodoptera exigua, and S. litura with entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae isolated from Gyeongbuk province were investigated. Mean lethal concentration ($LC_50$) values of B. bassiana and M. anisopliae against $2cdot3rd$ instar of A. segetum larvae were $1.2 imes10^7;conidia/mell$ and $5.2 imes10^6;conidia/mell$, respectively. $LC_50$ values of B. bassiana and M. anisopliae against $2cdot3rd$ instar of A, rapae larvae were $1.2 imes10^7;conidia/mell$ and $5.2 imes10^6;conidia/mell$, respectively. $LC_50$ values of B. bassiana and M. anisopliae against $2cdot3rd$ instar of M. brassicae and P. xylostella, larvae were $1.5 imes10^6;conidia/mell$, $9.7 imes10^5;conidia/mell$, $3.0 imes10^6;conidia/mell$ and $1.4 imes10^6;conidia/mell$, respectively. $LC_50$ values of B. bassiana and M. anisopliae against $2cdot3rd$ instar of S. exigua, and S. litura larvae were $6.3 imes10^6 ;conidia/mell$, $2.6 imes10^6;conidia/mell$, $1.6 imes10^7;conidia/mell$ and $3.4 imes10^6;conidia/mell$ respectively.
