摘　　要：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。Three parasitoids, Acerophagus coccois, Allotropa sp. and Zarhopalus debarri, introduced from America to control Oracella acuta （ Lobdell ） , were investigated in Guangdong forest after releasing in 1996- 2013. The results showed that A. coccois and Allotropa sp. were collected in the years of investigation, and Z. debarri was collected only release in 1997, since then the out of sight. A. coccois was collected in consecutive years, and the number is on the rise, indicates that it has been successful colonization and reproduction in Guangdong Forest, and can keep the population in certain, can continue to multiply and spread; Allotropa sp. was able to successfully overwintering and colonization in Guangdong Forest, but may not have been created a stable population, and Z. debarri was not collected in investigation years, may not colonize successly. Population dynamics of O. acuta in Guangdong forest, parasitoids strong control and weakly diffusion may be important factors influencing the introduced parasitoids to establish stable population in the forest.
