The ladybird beetle (Coccinella septempunctata Linn.) is a crucial predator of the aphids that feeds on them. The attention on biological control is largely a result of the development of pesticide resistance or resurgence as well as their toxicity to non-target organisms. Both beneficial and harmful insects are adversely affected by chemical insecticides. Natural enemies (predators or parasitoids) are applied in biological control to manage pest populations below dangerous level. The most efficient and eco-friendly approach of pest management is typically biological control. Aphids are controlled biologically by aphid-eating ladybirds, or "aphidophagous" insects. So, using predators to reduce or minimize pests and their impacts is a method of biological control that is maintain the pest defender ratio.
