用双盾恩蚜小蜂（Encarsia diaspidicola）进行了引入前宿主特异性试验，该生物防治候选物针对入侵性白色桃蚧（Pseudaulacaspis pentagona）。采用传统的无选择检验法对夹竹桃蚧、库克氏圆蚧、椰子蚧、毁灭盾蚧、苏铁蚧、白纹盾蚧、温室粉虱、温室白粉虱、绿色蚧、绿蚧和长尾粉蚧进行检疫检验，并对出蜂情况进行检查。夏威夷特有的棕榈鳞片，Colobopyga pritchartum也进行了测试，使用无选择测试和物种特异性分子标记进行评估。所有试验均使用未暴露的非目标队列和无选择暴露的白色桃圆蚧作为对照。没有一个非目标外来物种产生黄蜂出现，暴露于黄蜂没有影响的非目标物种的死亡率检查。对当地棕榈蚧进行的分子检测表明，没有证据表明E.双盾生。这些结果有力地支持了E.因此，在夏威夷释放该物质的非目标影响风险可以忽略不计。(C)2010年爱思唯尔公司All rights reserved.
Pre-introductory host specificity tests were performed with Encarsia diaspidicola, a biological control candidate against the invasive white peach scale, Pseudaulacaspis pentagona. False oleander scale, P. cockerelli, coconut scale, Aspidiotus destructor, cycad scale, Aulacaspis yasumatsui, greenhouse whitefly, Trialeurodes vaporariorum, green scale, Coccus viridis, and long-tailed mealybug, Pseudococcus longispinus were tested in quarantine using traditional no-choice tests and examined for wasp emergence. The Hawaiian endemic palm scale, Colobopyga pritchardiae was also tested using no-choice tests and evaluated using species-specific molecular markers. All tests used unexposed non-target cohorts and no-choice exposure of white peach scale to the parasitoid as controls. None of the non-target exotic species yielded wasp emergence, and exposure to wasps had no effect on the mortality of the non-target species examined. Molecular tests with the endemic palm scale showed no evidence of parasitism by E. diaspidicola. These results strongly support that E. diaspidicola has a narrow host range and that its release in Hawaii will have negligible risk of non-target effects. (C) 2010 Elsevier Inc. All rights reserved.
