【摘要】 1999～2003年,对云南省16个华山松分布区华山松球果受害情况进行了调查,结果表明云南省主要的华山松分布区华山松球果均遭受华山松球果螟不同程度的危害,受害率19．01％～67．39％,华山松球果螟在云南省的地理分布与其寄主华山松的地理分布基本一致。在云南省楚雄紫溪山林场的防治试验表明采用清除虫害果的防治措施对于控制华山松球果螟危害效果明显。更多还原

【Abstract】 During 1999-2003, the cone damage status of Pinus amandii was investigated in 16 areas in Yunnan province. The results showed that the cones of P. amandii in all areas investigated were damaged by Dioryctria rubella Hampson in different degree, and the damage rate was 19.01%-67.39%. The geographic distribution area of D. rubella was in agreement with the geographic distribution of its host plant, P. armandii in Yunnan province. And the control experiment in forest farm of Zixi Mountain indicated that it was a good method for controlling D. rubella to clear away the cones damaged by D. rubella.更多还原
