Susceptibility Of Pre-Adult Biological Stages Of Mythimna Separata (Walker) (Lepidoptera: Noctuidae) To Three Entomopathogenic Fungi (Hypocreales), Melissa P. Montecalvo, Marcela M. Navasero

The Philippine Agricultural Scientist

Armyworms are polyphagous insect pests of agricultural crops. Their population is usually managed below threshold level using insecticides. However, a single control measure is insufficient to attain a sustainable pest management. Hence, this research was conducted to assess the three species of entomopathogenic fungi as potential biological control agents against Mythimna separata (Walker) or paddy armyworm. Dose mortality assays were conducted to determine the pathogenicity of Beauveria bassiana (Bals.) Vuill., Metarhizium anisopliae (Metschn.) Sorokin, and Metarhizium rileyi (Farlow) Kepler, S.A. Rehner and Humber against various biological stages of M. separata including egg, 1^st to 6^th larval instars, prepupa, …
