对樟子松种实害虫及天敌曲姬蜂调查研究表明,球果象甲被害率在20%～40%左右,虫口密度为每果2～6头不等,棘梢斑螟有虫株率为26%,球果被害率为12%,虫口密度为每果1～2头不等,曲姬蜂的寄生率平均为25.4%,利用曲姬蜂生物防治樟子松种实害虫效果非常显著。
對樟子鬆種實害蟲及天敵麯姬蜂調查研究錶明,毬果象甲被害率在20%～40%左右,蟲口密度為每果2～6頭不等,棘梢斑螟有蟲株率為26%,毬果被害率為12%,蟲口密度為每果1～2頭不等,麯姬蜂的寄生率平均為25.4%,利用麯姬蜂生物防治樟子鬆種實害蟲效果非常顯著。

The studies on seed and cone insect pests of Pinus sylvestris var.mongolica and their parasitoid Scambus sp.indicate that,the infestation percentage of Pissodes validirostris Gyll is around 20%-40%,2-6 pests per cone.Dioryctria mutatella Fuchs were found in 26% of inspected plants,the infestation percentage is 26%,1-2 pests per cone.The average parasitic rates of Scambus sudeticus is 25.4%.Scambus sudeticus played an important role in biological controlling seed and cone insect pests of Pinus sylvestris var.mongolica.
