Definition - What does Beneficial Insect mean?
Beneficial insects are insects that have positive effects on a garden or landscape, as they aid in pollination and in some cases serve as natural pesticides.
Some predatory species of insects are the natural enemies of many common pest insects that often infest garden areas. Beneficial insects increase the ecological diversity of garden areas and defend plants and crops from harmful insect pests.
Beneficial insects may also be known as beneficial bugs.
MaximumYield explains Beneficial Insect
Beneficial insects are predatory and parasitic in nature and are often used as a pest control mechanism in organic farming and gardening or in integrated pest management (IPM). Such insects can be manually introduced into a garden habitat or they can be attracted naturally by growing pollen and nectar plants nearby. Some of these attractive plants include rose, cilantro, marigold, milkweed, and dandelion.
Beneficial insects also require adequate protection so that they can thrive and combat the garden pests. The most common and beneficial of these insects include ladybugs, lacewings, earwigs, assassin bugs, ground beetles, and tachinid flies.
Horticulturalists can buy these insects from companies that specialize in biological pest control. Beneficial insects are most effective in enclosed plant-growing areas, such as greenhouses and indoor gardens and plant nurseries.
The IPM program aims to use beneficial bugs for pest control in the early stages of pest development and use insecticides as a last resort. Beneficial insects have greater success rates when they are released while the pest populations are low to medium. They do not work as fast as pesticides or insecticides, so it takes time for beneficial insects to combat pests.
