Evaluation of new strain (AAD16) of Beauveria bassiana recovered from Japanese rhinoceros beetle: Effects on three coleopteran insects.

ABSTRACT: A strain (AAD16) of the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin was isolated from field-collected Japanese rhinoceros beetle, Allomyrina dichotoma (L.) (Coleoptera: Scarabaeidae). Its virulence was compared with another strain (ARP14) recovered from a cadaver of Riptortus pedestris (F.) (Hemiptera: Alydidae) focusing on its effect on three coleopteran, i.e., Tenebrio molitor L., A. dichotoma, and Monochamus alternatus Hope. The LT50 value of T. molitor for two larval sizes, i.e., 16-18 and 22-24 mm, was 15.3 and 19.4% lower for strain AAD16 compared to strain ARP14, respectively. Furthermore, after 8 and 10 days of exposure, the mycosis rate of strain AAD16 was 1.3 and 1.2 times higher than that of strain ARP14 in the 16-18 and 22-24 mm larval sizes, respectively. Th
