Outline of Final Research Achievements

Entomopathogenic fungi play important roles in terminating population outbreaks of forest defoliating insects. Mortality by the fungi was > 90% and < 10% for the beech caterpillar, Syntypistis punctatella and the larch sawfly, Pristiphora erichsonii, respectively. Density dependent mortality factors that were effective during population outbreaks of P. erichsonii were not detected. Specific primer sets for qPCR were successfully developed for Cordyceps militaris, Beauveria bassiana, Isaria fumosorosea, and Metarhizium anisopliae but failed for B. brongniartii and I. farinose. Methodology in DNA extraction from soils seemed necessary to be improved.
