| Abstract: | Modified White's solution (1 g HgCl2/l H2O) is widely used to surface disinfest bark beetles of their phoretic fungi. We investigated the effectiveness of this solution at disinfesting adult Ips pini from its associated ophiostomatoid fungi. A treatment for 1, 4 or 8 min does not completely rid beetles of phoretic fungi, but does substantially reduce the amount of fungi they carry externally. Sterilizing with modified White's solution caused limited mortality (<16%). |
