| 摘 要： | 异绒螨(Allotrombium sp.) 在北京、山东临沂地区每年发生一代,以成螨越冬。成螨和若螨可捕食膜肩网蝽(Hegesidemus habrus Drake)若虫,对膜肩网蝽种群数量有控制作用。异绒螨越冬前不产卵,翌年春产卵,幼螨营寄生生活。菜蚜是室内饲养异绒螨的好饲料,可缩短生活历期,有利于林间释放。在杨树幼林中,以若螨与膜肩网蝽1:50释放,膜肩网蝽虫口减退率达76.01％。人工助迁成螨,在林间亦易定居。

| Abstract: | The mite, Allotrombium sp. is a predator of the tingid, Hegesidemus habrus. It has one generation a year in Beijing and Lin Yi area, Shangdong province. It overwinters in the adult stage and eggs are laid in the soil in the following spring. Both the nymph and adult of this mite .can prey on the tingid nymph. The population of the tingid could be controlled by the mite. It is found that the cabbage aphid, Brevicoryne brassicae can be used as food for the mite. The peroid of the mite's life cycle can be shortened, if the mite is reared with this aphid. Releases were made according to the predator:pest ratio as 1:50. The population of the tingid could be reduced by 76.01 %. The effect of mass-releasing of this mite in young stands is quite promising. Generally, its colony is easy to be established. |
