寄生蜂抗药性研究进展

植物-植食性昆虫-寄生蜂三级营养结构之间由于长期相互适应和协同进化，产生了一系列独特的相互关系。选择压力将对害虫和寄生蜂的抗药性演化产生影响，但由于寄生蜂具有与植食性昆虫不同的生物学及生态学特性，选择压力对害虫和寄生蜂抗药性演化的影响作用也是不同的。研究结果表明，除体外杀虫剂对寄生蜂的直接汰选因素外，进入寄主昆虫体内的杀虫剂成分、寄主昆虫取食不同植物的特有成分以及气候因子等均会对寄生蜂的抗药性演化产生影响。

Advances in evolution of insecticide resistance in parasitoid wasps

Specific interactions were involved in host plant_herbivore_parasitoid system based on the adaptive strategies and coevolution on tritrophic interactions. The evolution of insecticide resistance in both herbivore and parasitoid wasps was affected by selection pressure. However, different evolution models of insecticide resistance might exist in parasitoids and herbivores with different biological and ecological characteristics. The present results showed that the evolution of insecticide resistance in parasitoids could be affected either directly by exposing to the spray in the field, or indirectly by the factors including the insecticides penetrated into the body of host insects, plant allelochemicals fed by host insects, and climatic factors.
