Abstract

The natural occurrence of beauveriosis in Dryocoetes confusus (Swaine) in Abies lasiocarpa (Hook.) Nutt. in British Columbia is reported, and the pathogenicity of Beauveria bassiana (Bals.) Vuill. isolated from D. confusus was confirmed experimentally. Also, direct observations of newly established pairs of D. confusus in glass – phloem sandwich cultures showed that cadavers of B. bassiana-killed females were walled-off with frass by healthy males.

Résumé

L'incidence naturelle de la beauveriose chez Dryocoetes confusus (Swaine) qui parasite Abies lasiocarpa (Hook.) Nutt., en Colombie-Britannique, est signalée. La pathogénicité de son agent, Beauveria bassiana (Bals.) Vuill., obtenu de D. confusus a été confirmée expérimentalement. En outre, des observations directes de paires de D. confusus récemment établies dans des sandwiches de verre et de phloème ont montré que les mâles sains ont emmuré les cadavres des femelles tuées par B. bassiana derrière leurs débris et leurs excréments.
