Abstract
Abstract Infection of Bacillus thuringiensis (Bt), Beauveria hassiana , and Metarhizium anisopliae to egg, larval, and pupal stages of the Asian corn borer, Ostrinia furnacalis , was studied. Two fungal pathogens were infective to all three stages, while Bt is only pathogenic to the larval stage. Evaluation of efficacy of three entomopathogens to the corn borer on sweet corn was undertaken in a screen house. Both Bt preparations and B. bassiana cultured on wine derivatives and mixed with sand to form granules at 2 × 10 8 conidia/g were as effective as carbofuran in screen house tests. Zusammenfassung Untersuchungen zur Infektion von Ostrinia furnacalis Guenee (Lep., Pyralidae) mit Entomopathogenen unter Gewächshausbedingungen Es wurde die Infektion von Eiern, Larven und Puppen von Ostrinia furnacalis mit Bacillus thuringiensis (Bt), Beauveria bassiana und Metarhizium anisopliae untersucht. Die beiden Pilze waren pathogen für alle drei Entwicklungsstadien, während Bt nur auf Larven wirkte. Die Wirksamkeitsprüfung der drei Pathogene wurde im Gewächshaus durchgeführt. Sowohl Bt als auch B. bassiana , auf Weinderivaten kultiviert und mit Sand vermischt, um Granulate von 2 × 10 8 Konidien/g auszubilden, waren in den Gewächshausversuchen ebenso wirksam wie Carbofuran.
