Influences of leaf-mining insects on their host plants: A review.— Leaf-mining insects are an herbivore group whose larvae live and feed inside plant leaves. Leaf mines are distinct marks on leaves and can provide much information on insect-plant relationships. Most leaf miners are monophagous or oligophagous. Therefore ecologists and paleontologists use them to study interactions and coevolution among plants, insects and natural enemies. There are many different types of leaf-mining patterns on plant leaves, which may have different impacts on host plants. Compared with ectophagous herbivores, leaf-mining insects should have unique influences on host plant characteristics, such as leaf morphology, leaf chemistry, plant physiology, plant growth and production. Obvious impacts include leaf asymmetry, callus formation, photosynthesis, and green islands. Types and degrees of such influences are varied for different leaf miner species or different host plant species. In turn, the change of plant features may have positive or negative impacts on oviposition and feeding of leaf-mining insects. Studies on plant responses to leaf-mining and the defensive mechanisms of plants are helpful in understanding the coevolution between leaf miners and their food plants.
