Behavioral management and application of Beauveria bassiana in the mass movement for the prevention and control of pine caterpillars focused on biological control were rapidly developing in our province. In 1976, there were over 400 production sites for the production of Beauveria bassiana The original powder amounting to 830 tons increased threefold over 1975, and the pest control area was 1.186 million mu, a doubling of that of 1975.
