Biological pest control refers to the use of living organisms to suppress pest populations, making them less damaging than they would otherwise be. In agriculture and allied sectors, it is an essential component of sustainable crop production and integrated pest management. Unlike chemical pesticides, biological control relies on natural enemies and ecological processes to regulate pest populations, thereby reducing environmental pollution, pesticide residues, and resistance problems. The various biological pest control methods can be broadly classified into the use of predators, parasitoids, pathogens, and other biologically based techniques such as sterile insect technique and conservation of natural enemies. Predators are free-living organisms that consume a large number of prey during their lifetime. They play a vital role in controlling insect pests in field crops, horticultural crops, and plantations. Common predatory insects include ladybird beetles, lacewings, praying mantids, dragonflies, spiders, and predatory bugs. For example, ladybird beetles feed on aphids, whiteflies, and scale insects in crops like cotton, vegetables, and fruit orchards. Chrysoperla species, commonly ______ _______ ___ ____ ___ ________.
