三叶斑潜蝇Liriomyza trifolii（Burgess）（双翅目：潜蝇科）是世界性的观赏植物和蔬菜害虫。控制温室斑潜蝇最有前途的非化学方法是定期释放寄生虫Diglyphus isaea（步行者）（Hytera：Eulophidae）。在目前的研究中，我们检查的假设，使用D。如果辅之以昆虫不育技术等其他防治策略，利用国际农业生物学协会的方法对温室作物中的潜叶虫进行生物防治，可能会更加实用和有效。在小笼子里，我们的SIT实验表明，无菌L。三种不育与可育雄性比例（3：1、5：1和10：1）的MFOLII雄性可以显著减少害虫后代的数量。在大型笼实验中，当寄生蜂和不育男性每周释放，相结合的方法显着降低了矿山生产和成年斑潜蝇人口规模。此外，这两种方法之间的协同作用的效果被发现，和一个模型的基础上，我们观察到的数据预测，由于这种效果，只有使用这两种方法可以消除害虫种群。我们的研究表明，一个综合的害虫管理方法，结合增强释放的寄生蜂D。国际原子能机构与不育的潜叶蝇雄性一起使用比单独使用任何一种方法都更有效。此外，我们的研究结果验证了以前的理论模型，并证明协同控制释放的寄生蜂和不育昆虫。
The leafminer Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) is a worldwide pest of ornamental and vegetable crops. The most promising nonchemical approach for controlling Liriomyza leafminers in greenhouses is regular releases of the parasitoid Diglyphus isaea (Walker) (Hymenoptera: Eulophidae). In the current study, we examine the hypothesis that the use of D. isaea for biological control of leafminers in greenhouse crops may be more practical and efficient when supplemented with additional control strategies, such as the sterile insect technique (SIT). In small cages, our SIT experiments suggest that release of sterile L. mfolii males in three sterile-to-fertile male ratios (3:1, 5:1, and 10:1) can significantly reduce the numbers of the pest offspring. In large cage experiments, when both parasitoids and sterile males were released weekly, the combined methods significantly reduced mine production and the adult leafminer population size. Moreover, a synergistic interaction effect between these two methods was found, and a model based on our observed data predicts that because of this effect, only the use of both methods can eradicate the pest population. Our study indicates that an integrated pest management approach that combines the augmentative release of the parasitoid D. isaea together with sterile leafminer males is more efficient than the use of either method alone. In addition, our results validate previous theoretical models and demonstrate synergistic control with releases of parasitoids and sterile insects.
