| 摘 要： | 赤松梢斑螟(D ioryctria sylvestrellaRatzeburg)主要以幼虫危害红松幼林的球果、嫩梢和干部,造成红松种子产量下降、质量低劣,严重的可导致红松种子绝产。为了解决红松种子严重短缺的问题,利用2.5%溴氰菊酯、20%速灭杀丁、50%辛硫磷和40%氧化乐果等化学药剂,在黑龙江省苇河林业局林木种子园进行了赤松梢斑螟防治试验。试验结果表明,球果被害率可减少20%~85%,种子被害率减少25%~45%。

| Abstract: | Dioryctria sylvestrella, of which the larvae bored the cone , shoot and stem of Korean pine, resulted in the reduction of the seed yield. To resolve the problem of shortage of seeds of Dioyctria sylvestrella, using concentration of 2.5% deltamethrin, 20% fenvalerate ,50% phoxim, 40% ometboate, control experiments against Dioryctria sylvestrella were conducted in forest seed orchord of Weihe Forestry Bureau in Heilongjiang Province. Results showed that the cone damage rate reduced 20% -85%, and 25% -45% for seed damage. |
