近年来，全球变化是镶嵌景观中害虫频繁、大范围爆发的主要原因，受到世界范围内的广泛关注。我们收集了1951-2010年中国6种主要害虫造成的全球变化（景观和气候）和经济损失数据。景观变化对6种害虫均有显著影响。农业景观中，随着耕地面积的增加，害虫危害显著增加。然而，气候变化对害虫造成的损害没有影响，除了稻纵卷叶螟（Cnaphalocrocis medinalisGuenee）和粘虫（Mythimna separate（步行者）），这对作物造成的损害较小，随着平均温度的升高。我们的研究结果表明，气候变化对这两种农业害虫造成的损失增加可能产生抵消作用的证据很少。景观的变化已经引起了几个物种的严重爆发，这表明可能使用景观设计通过生境重排控制害虫种群。景观操作可以作为一种绿色方法，以实现可持续的害虫管理与最低限度的使用杀虫剂和除草剂。
In recent years, global changes are the major causes of frequent, widespread outbreaks of pests in mosaic landscapes, which have received substantial attention worldwide. We collected data on global changes (landscape and climate) and economic damage caused by six main insect pests during 1951–2010 in China. Landscape changes had significant effects on all six insect pests. Pest damage increased significantly with increasing arable land area in agricultural landscapes. However, climate changes had no effect on damage caused by pests, except for the rice leaf roller (Cnaphalocrocis medinalisGuenee) and armyworm (Mythimna separate(Walker)), which caused less damage to crops with increasing mean temperature. Our results indicate that there is slight evidence of possible offset effects of climate changes on the increasing damage from these two agricultural pests. Landscape changes have caused serious outbreaks of several species, which suggests the possibility of the use of landscape design for the control of pest populations through habitat rearrangement. Landscape manipulation may be used as a green method to achieve sustainable pest management with minimal use of insecticides and herbicides.
