IPM aims to manage pest populations, not eliminate them completely. The goal is to keep pest populations below a level that causes economic damage to crops or other resources.

Chemical pesticides are not a non-chemical method of pest control. They are used as a last resort in IPM when other methods have failed to control the pest population.

Releasing ladybugs to control aphids is an example of biological control. Ladybugs are natural predators of aphids and can help to reduce aphid populations.

Crop rotation, intercropping, and sanitation are all examples of cultural practices used in IPM. Crop rotation helps to disrupt pest life cycles, intercropping can help to confuse pests and make it more difficult for them to find their host plants, and sanitation helps to remove potential pest habitats.

All of the options are examples of host-plant resistance. Plants can produce chemicals that are toxic to pests, have a thick cuticle that makes it difficult for pests to penetrate, or produce trichomes that can trap and kill pests.

All of the options are disadvantages of using chemical pesticides. Chemical pesticides can kill beneficial insects and other organisms, contaminate the environment, and lead to the development of pest resistance.

IPM can help to reduce the need for chemical pesticides, protect beneficial insects and other organisms, and reduce the development of pest resistance, but it does not necessarily increase crop yields. Crop yields are influenced by a variety of factors, including weather, soil conditions, and crop management practices.

Maximizing profits is not a principle of sustainable agriculture. Sustainable agriculture aims to balance economic, environmental, and social goals.

IPM is not always more expensive than conventional pest control methods. In fact, it can often be more cost-effective in the long run.

IPM is not typically used in aquaculture, which is the farming of fish and other aquatic organisms. However, IPM can be used in other agricultural systems, such as conventional agriculture, organic agriculture, and permaculture.
