摘要
马尾松枝梢害虫主要包括微红梢斑螟、松实小卷蛾、油松球果小卷蛾、松果梢斑螟等。在春季蛀食幼树嫩梢髓部,被害梢弯曲枯死,影响幼树高生长和材质。近年来生产上应用林业措施、化学和生物防治等综合治理来抑制害虫数量。具体方法是剪除被害梢果,营造混交林,幼虫孵化盛期喷洒氯氰菊酯和氧化乐果混合剂,卵期释放赤眼蜂。防治微红梢斑螟还可在成虫期设置性诱剂(Z_(11-16):AC、Z_(11-16):ALD、Z_9E_(11-14):AC)诱捕器诱杀。
The major shoot pests of Pinus massoniana are Dioryctria rubella Hampson,Petrova cristata Walsingham,Gravitarmata margarotana Hein,D.pryeri Ragonot etc.In spring,the pests bore and eat pith in shoots,the damaged shoots then bend and wither,which directly affect the heigh growth of young pine and wood quality.Recently the IPM measures including forest management,chemical and biological control have been used to reduce th pest's population in the forest production.The practical methods are cutting down the damaged shoots and cones,planting mixed forests,spraying the mixture of cypermethrin and omethoate during full larva hatch period and releasing Trichogramma dendrolimi during egg stage.Traps with sex-attractants(Z_(11-16):AC,Z_(11-16):ALD,Z_9E_(11-14):AC) can also be set up to control D.rubella during adult period.
