1996-2013年调查了三种美国引进寄生蜂-火炬松短索跳小蜂Acerophagus coccois、广腹细Allotropa sp.和迪氏跳小蜂Zarhopalus debarri在广东林间释放后定居的情况。结果表明,火炬松短索跳小蜂与广腹细蜂在多年调查中均能采集到,而迪氏跳小蜂仅在1997年释放当年采集到,此后难觅踪影。火炬松短索跳小蜂连续多年均能采集到,而且数量呈上升趋势,表明其已成功在广东林间定殖和繁殖后代,并能保持一定的种群数量,能继续繁衍与扩散;广腹细蜂则在广东林间成功地越冬与定殖,可能尚未建立起稳定的种群,而迪氏跳小蜂多年调查没有采集到,可能定殖不成功。推测广东林间湿地松粉蚧种群消长、寄生蜂较强的控害作用和较弱的扩散力可能是影响引进寄生蜂在林间建立稳定种群的重要因素。
In 1996-2013, three United States species were surveyed: the introduction of Acerophagus coccois, the broadleaf Allotropa sp. And the Zarhopalus debarri, a parasitic wasp settled in Guangdong Province. The results showed that the small flamingo jumping wasps and the broadleaf bee can be collected in many years of investigation, but the Dipper jumping bee was only released in 1997 when it was released, after which it is hard to find traces. The success rate of Pinus tabulaeformis was able to be collected for many years in succession, and the quantity was on the rise, indicating that it had successfully colonized and multiplied offspring in the forest of Guangdong and maintained a certain population quantity, which could continue to multiply and spread. The bee was successfully overwintering and colonizing in the forest of Guangdong, may not have established a stable population, but Didier’s hop wasp was not collected for many years and may not colonize successfully. It is speculated that the population dynamics of Myzus persicae in the inter-forest wetland in Guangdong Province may be an important factor that may affect the establishment of a stable population in the forest.
