Title: Characterization of Beauveria bassiana MsW1 isolated from pine sawyers, Monochamus saltuarius. Author: Shin TY, Choi JB, Bae SM, Koo HN, Roh JY, Je YH, Jin BR, Woo SD. Journal: J Basic Microbiol; 2011 Oct; 51(5):531-9. PubMed ID: 21656803. Abstract: Monochamus saltuarius is a vector for pine wilt disease that causes enormous damage to native pine trees in Korea. To develop a biological control method for this pine wilt disease vector, an entomopathogenic fungus was isolated from the cadaver of an adult M. saltuarius supporting fungal conidiation. This fungus was named MsW1 and identified as Beauveria bassiana by microscopic examination, PCR amplification using B. bassiana -specific primers and genetic sequencing of the ITS and EF1-α regions. Virulence tests against M. saltuarius were conducted with conidial suspensions (1 × 10(8) conidia/ml) of B. bassiana MsW1 in laboratory conditions. The median lethal times (LT(50)) of adults and larvae were 7.2 and 7 days, and 100% mortality was observed at 11 and 13 days after inoculation, respectively. This is the first characterization of B. bassiana from M. saltuarius.[Abstract] [Full Text] [Related] [New Search]
