Aims: Conidium production by three species of insect pathogenic fungi,Metarhizium anisopliae,Beauveria bassianaandVerticillium lecanii , was assessed on various depths and types of commercially available agars. Methods: Conidium production was assessed after 14 d of growth on commercially available media as well as at three different agar depths. Results: Metarhizium anisopliaeandB. bassianaisolates showed greatest conidium production on potato dextrose agar (PDA) at a depth of 2 mm, whereasV. lecaniishowed greatest conidium production on yeast extract‐peptone‐dextrose agar (YPDA) regardless of agar depth. Optimum conidium production forM. anisopliaeandB. bassiana was not only dependent upon the isolate used but also on the medium type and agar depth. Significance and Impact of the Study: Conidia are the infective structures for insect pathogenic fungi and this study suggests a rationale basis for consistent conidium production for laboratory and commercial practices.
