【Abstract】 Population dynamics of major Coleoptera insects in mature and immature pine forest distributed under the altitude of 100 m in northern piedmont of Kuocang Mountain were investigated by using traps and attractant in 2005—2006.Results showed that there were 33 Coleoptera species,belonging to 9 families,damaging masson pine,either pine needles or branches and trunk,and 1 natural enemy species.Of the insect pests,3 were victors of the fatal pine disease PWN,i.e.Monochamus alternatus,Spondylis buprestoides,and Shirahoshizo patruelis.In the trial forest compartments,Cerabycida,Curculionidae and Scolytidea were the dominant groups with both species number and total insect individuals attracted.Important adult characteristics of major species,esp.Monochamus alternatus were analyzed and suggestions on prevention and control of these major species were given.更多还原
