Of the thousands of aphid species that exist globally, only a few have developed insecticide resistance. However, some of these are ranked among the most problematic pests worldwide. Some species feed on a wide range of hosts, while others are virtually confined to a single plant species. They damage agricultural and horticultural crops through direct feeding, the transmission of plant viruses, and by their impact on the aesthetic value of crops (by depositing honeydew or simply by being present).
