Abstract

<p><em>Metarhizium</em> spp. is one of the entomopathogenic fungus that can be used to control <em>Spodoptera litura</em>. The purpose of this research was to study the pathogenicity of <em>Metarhizium</em> spp. to<em> Spodoptera litura</em> eggs. The isolates were collected from rhizosphere of different crops i.e., cabbage, onion, leek and chili. The results showed that there was effect of all isolates on egg mortality. Mortality of <em>S. litura</em> eggs depend on the fungal isolates, ranged between 19.79%-75.70%. First instar larvae was also died 3 days after eclosion. The maximum mortality of first instar larvae was 58.65%. At a concentration of 108 conidia/ml, isolate Mt-kb had the highest virulence which caused higher mortality of eggs and first instar larvae.</p>
