PRODUCTION, FORMULATION AND APPLICATION OF THE ENTOMOPATHOGENIC FUNGUS BEAUVERIA-BASSIANA FOR INSECT CONTROL - CURRENT STATUS

This review summarizes the progress and achievements made in the last decade in mass production formulation and application technology of the entomopathogenic fungus, Beauveria bassiana. Reports published on relevant research from Belgium, Canada, China, Cuba, Czechoslovakia (former), France, Germany, Great Britain, Philippines, Poland, Switzerland, USA and USSR (former) regarding this topic have been covered. Much of the non-English language literature, particularly that from Eastern European and Chinese sources, has not been translated and is inaccessible to most English or other western language readers. We have done this translation and through this review provide technological details about mass production of B. bassiana in China. Various aspects of B. bassiana growth, substrate use, production of mycelia, conidiospore and blastospores, process technologies associated with separation, drying and milling, formulation, storage and 'shelf-life', and field efficacy are reviewed. Data are presented on: a modified diphasic production technology developed in China during the 1980s; comparisons between submerged fermentation, which usually produces blastospores, and those producing conidia; the use of mycelial preparations pelletized with alginate or gelatinized with cornstarch or cornstarch-oil; and data on low or ultra-low volume sprays of emulsifiable or oil conidial suspensions and dust formulations. B. bassiana has proved to be competitive with chemical insecticides for the annual protection of 0.8-1.3 million hectares against forest and farm insect pests in China. It is hoped that this review will help to bridge the language gap between eastern and western scientists in microbial control using B. bassiana.
