The Studies of Spom dylis buprestoides Adult Popula tion and Dynamic Monitoring

Studieswere made on S pondylis buprestoides adult population distribution and dynamic regularitywith liquid wood2boring insect attractant in Huangshan Scenic Area and other area. The results showed that the area with thealtitude 1 700 m was the highest distribution zone of S. buprestoides population,while high population density distribution area wasMasson p ine stand with the altitude cower them300 m. There were two peakes in adult action duration ( about 150 days). The main peak appeared in the first and middle ten days of June, while the second peak appeared in Sep tember. The population quantity p roportion of S pondylis buprestoides female and male adultswas 1. 0∶1. 4 .
