Biological controls—Natural biological processes and materials can provide control, with acceptable environmental impact, and often at lower cost. The main approach is to promote beneficial insects that eat or parasitize target pests.
Biological pest control is a rapidly expanding field of agriculture, where natural agents, primarily parasitoids and predators are used to control a pest organism that has been causing economic harm to human interests. These methods can be as alternatives or supplements to conventional pest control methods such as insecticides.
The sterile insect technique (SIT) [1] [2] is a method of biological insect control, whereby overwhelming numbers of sterile insects are released into the wild. The released insects are preferably male , as this is more cost-effective and the females may in some situations cause damage by laying eggs in the crop, or, in the case of mosquitoes ...

A Biopesticide is a biological substance or organism that damages, kills, or repels organisms seens as pests. Biological pest management intervention involves predatory, parasitic, or chemical relationships. They are obtained from organisms including plants, bacteria and other microbes, fungi, nematodes, etc.
Further examples of environmental control is by reducing the prevalence of open defecation or improving the designs and maintenance of pit latrines. This can reduce the incidence of flies acting as vectors to spread diseases via their contact with feces of infected people.
Bioherbicides are herbicides consisting of phytotoxins, pathogens, and other microbes used as biological weed control. [1] Bioherbicides may be compounds and secondary metabolites derived from microbes such as fungi, bacteria or protozoa; or phytotoxic plant residues, extracts or single compounds derived from other plant species.
