摘要：思茅松微红梢斑螟Dioryctria rubella Hampson在云南省普洱市1年发生3代,世代重叠现象严重。幼虫具有转梢、转枝、转株为害习性,这与气候因素和寄主思茅松的生长状态密切相关。雨季幼虫以转株危害为主,危害率为35%～40%;旱季幼虫以转梢危害为主,危害率为90%～100%。第3代微红梢斑螟发生严重,造成的损失最大。这为综合控制微红梢斑螟对思茅松的危害提供重要的理论基础。
Dioryctria rubella Hampson caused severe damage to Pinus kesiya var.langbianensis Chev.in Pu＇ er city,Yunnan province has 3 generations a year and overlap extensively according to the field and laboratory observations of its biology and ecology.Its larvae infest shoots of pines and have the habit of transferring shoots,branch,and plant which based on the climate and the development conditions of its host.In the rain season,the damage rate is 35%-40% via the action of tranferring plant.In the dry season,the damage rate is 90%-100% via the action of transferring shoots.The third generation of D.rubella can cause more damage than the first and second one.The research results can facilitate the management of D.rubella.
