摘　　要：通过野外对小蠹虫天敌种类调查,发现其主要天敌种类有郭公甲(Clerus dealbatus Kraatz)、小蠹蒲螨(Pyemotes scolyti Oudemans)、果树四斑金小蜂(Cheiropachus qucdrum Fabricius)、白翅啄木鸟(Dendrocopoleucopterus)等。在对小蠹蒲螨进行寄生能力的初步研究结果表明,在26～29℃条件下,小蠹蒲螨完成1代需7～14d,单头膨腹体产螨量为(60.6±3.8)头,其中雌性占产螨总量的93.7%～98.0%,在杏园内释放小蠹蒲螨,多毛小蠹的寄生可达48.0%。Several natural enemies of bark beetle such as Clerus dealbatus Kraatz, Pyemotes scolyti Oude- roans, Cheiropachus qucdrum Fabricius,Dendrocopo leucopterus were found in the field. The parasitic abil- ity of Pyemotes scolyti Oudemans was also studied. Results showed that in the condition of 26-29 °C Pyemotes scolyti Oudemans can finish one generation in 7-14 d. Mature Pyemotes scolyti Oudemans which account for 93.7% - 98.0% of the total amount of female mite reproduction. The parasitic rate of Scolytus seulensis Murayama in apricot orchard is high,up to 48.0%.
