Climate change can have a variety of consequences on pest species natural enemies. Here, we look at these consequences and how they could affect pest control. Natural enemies fitness can be influenced by variations in herbivore size and quality brought on by CO2 and temperature and impacts on plants. Herbivore vulnerability to predation and parasitism might be reduced by increasing plant leaf output or changing the timing of herbivore life cycles in respond to plant phonological changes. If insect distributions change outside the range of their natural enemies, their efficiency in managing pests will decline, while a new group of enemies may provide some amount of control. Natural enemies abundance and activity will be influenced by farmers adaptive management practises to deal with climate change, in addition to being influenced by climate by host plants and related herbivores. These tactics may cause a spatial and temporal incompatibility between pests and enemies, reducing bio control efficiency. Predictions will be difficult unless there is a good understanding of how environmental effects impact tritrophic interactions due to the various and often indirect effects of climate change on natural enemies.
