What term refers to the release of predators or parasites to control insect pests?

1. Biological warfare

2. Pesticide resistance management

3. Monitoring and baiting

4. Biological control

The correct answer is: Biological control

The term that describes the release of predators or parasites to manage insect pest populations is "biological control." This practice utilizes natural enemies, such as certain insects, birds, or even microorganisms, to reduce the numbers of pest species in an environmentally friendly manner. By harnessing these natural relationships, biological control can effectively lower pest populations without the adverse environmental impacts associated with chemical insecticides. In situations where pests are pressing, introducing beneficial organisms can alleviate the need for synthetic treatments. It's also notable that biological control often leads to more sustainable pest management, as it promotes biodiversity and reduces reliance on chemicals, aligning with integrated pest management strategies. The other options refer to different concepts; for instance, biological warfare typically relates to the intentional use of pathogens or toxins in military contexts, pesticide resistance management focuses on strategies to prevent or delay the development of resistance in pest populations to chemical controls, and monitoring and baiting are specific pest control techniques that do not involve the introduction of biological agents.
