    Abstract

    The purpose of this research was to explore and examine the potential of soil borne entomopathogenic fungi species from South Sumatera as biological agents of Leptocorisa oratorius (F). Soil used for trapping entomopatogenic fungi, was taken from five locations in South Sumatera. Percentage of nymph mortality was analyzed by using analysis of variance and arranged in Completely Randomized Design. LT50 of nymph mortality was determinad with Probit Analysis. Entomopathogenic fungi spesies found in this research were Beauveria bassiana and Metarhizium sp. Stink bug mortality if B. bassiana isolates applied reached 40% to 73.3% and Metarhizium sp reached 56.7% to 70%. The results showed that the Metarhizium isolates were more virulent than B. bassiana isolates. The viability of B. bassiana conidia did not decrease during sub-culturing. Sub-culturing did not influence mortality percentage of stink bug nymph but it prolonged the LT50 of the stink bug.
