摘要
在广东省森林病虫害防治与检疫总站昆虫繁育室,用接种了湿地松粉蚧的湿地松和火炬松盆栽幼树,繁殖从美国引进的湿地松粉蚧寄生天敌——火炬松短索跳小蜂、迪氏跳小蜂和粉蚧广腹细蜂,连续10年成功繁殖出子代蜂,并长期保持一定的种群数量。释放的亲代寄生蜂数量与检查到的子代寄生蜂数量的比例为6∶1。
Acerophagus coccois, Zarhopalus debarri, Allotropa oracellae, natural enemies of loblolly pine mealy bug, Oracella acuta, introduced from USA were successfully reared in insect rearing facilities with potted slash and loblolly pine seedlings infested by 0. acuta.
