抽象的生物控制现在被公认为是一种环境，技术上适当的，经济上可行的害虫控制方法。The injudicious use of insecticides nowadays pose a threat to both the populations of target pests and beneficial insects.According to recent studies, IPM programs can be improved by establishing pesticide-resistant parasites that were chosen in the lab and then released into the field.The efficacy of natural enemies may be increased by a variety of characteristics, such as tolerance to pesticidal stress, tolerance to severe abiotic stressors,缩短发育率，后代产量的增加，性别比的变化以及宿主或栖息地偏好的变化。通过分子方法改善特征的“实验室生物”的开发可以提高其效率，从而提供保证的虫害控制率。因此，我们应该在分子生物学领域中利用新兴技术，以便在害虫管理过程中可以成功操纵“农民”朋友。关键词：生物控制，IPM，自然敌人，农药，害虫管理
