AbstractThe pathogenicity of nine fungi was tested in the laboratory against Holotrichia sp. Ail the fungi proved to be pathogenic at a spore concentration 1 í— 108 spore/ml to grub with varied mortality. Beaitveria bassiana (Local), B. bassiana (commercial), B. brongniartii and Metarhizium anisopliae were found to be the most effective. B. bassiana @ 1x108 spore/ml concentration inflicted initial mortality on 6th day (46.6%) and cent per cent mortality was observed on 12th day. In B. brongniartii initial mortality started on 8th day (33.33%) and cent per cent mortality occurred on 20th day, while as in case of M. anisopliae mortality was initiated on 8th day (30%) and highest mortality was observed on 20th day (93.91%). In the field, all the three screened bioeontrol agents caused heavy mortality at the highest concentration of 1x108 spore/ml. However, B. bassiana was found most effective as compared to the rest. In case of B. bassiana, the first mortality was observed on 10th day (36.66%) and cent per cent mortality occurred on 20th day, while in case of B. brongniartii and M. anisopliae the first mortality was observed on 10th and 12th day and complete mortality was observed on 22nd and 24th day, respectively.
