Explanation:
Pest management is a type of program aimed at controlling pests and minimizing their impact on the environment, human health, and the economy. It encompasses a variety of strategies, including the use of pest-resistant crops, introduction of sterile males, use of natural pest predators, and various others methods.
Management of pests doesn't only rely on the use of chemicals but also emphasizes on environmentally friendly and sustainable practices. For instance, one technique is to increase the diversity of pest enemies, which proved effective in increasing the yield of alfalfa as per one study.
Another approach followed in pest management is the usage of sterile male introductions, where lab-reared males of the target species are sterilized and released into the environment to mate, resulting in no live offspring. Repeated releases can significantly reduce the pest population. Additionally, certain plants also serve as natural repellents and protect the plants from pests.
