Title: POSSIBILITY OF USING WHITE AND GREEN MUSCARDINE FUNGI FOR CONTROL OF CONE AND SEED INSECT PESTS
Abstract: Abstract Preconditioning of isolates of Beauveria bassiana (Bals.) Vuill. and Metarrhizium anisopliae (Metch.) Sor. with specific insects increases their virulence. An isolate of B . bassiana used two years previously in pathogenicity tests against spruce budworm, Choristoneura fumiferana Clem., required only one passage through this insect to attain 100% mortality in 48 h of incubation, whereas an isolate of M . anisopliae that was not previously used against this insect required four passages to attain the same degree of virulence as B . bassiana . Larvae of Laspeyresia youngana (Kft.), Dasineura rachiphaga Tripp, and Dasineura canadensis Felt were very susceptible to both fungi and 100% mortality was obtained in less than 48 h of incubation. Larvae of Lasiomma anthracina Czerny were much less susceptible. Puparia of both genera of Diptera were more resistant than larvae and required longer incubation to obtain 100% mortality.
