Abstract: The colony growth and sporogenous conditions of the highly pathogenic strain Bxs of Beauveria bassiana on pine sawyer Monochamus alternatus,and the virulence of Bxs to pine sawyer Monochamus alternatus were studied. The results showed that the growth temperature for Bxs ranged from 20 to 30 ℃,and 25 ℃ was optimal for both colony growth and sporulation,but the colony growth stopped at 35 ℃. For growth and sporulation,DPSA was the desirable culture medium. Virulence tests indicated that great variations existed in disease susceptibility among different developmental stages of Monochamus alternatus,and higher disease sus-ceptibility occurred in the juvenile stages. The equation of dose-mortality and LC50 of the third instar were y=-1.388 4+0.996 7x and 3 936 sporesmL-1 respectively. Based on the Three-dimensional Relation of time-dosage-mortality,a complementary log-log model (CLL model) of Bxs virulence to third instar M. alternatus was constructed.[Ch,3 fig. 7 tab. 11 ref.]
