In agriculture, where the goal is to raise selected crops, insects that hinder the production process are classified as pests, while insects that assist production are considered beneficial. In horticulture and gardening, beneficial insects are often considered those that contribute to pest control and native habitat integration.
Many weed species attract beneficial insects that improve soil qualities and forage on weed pests. [6] Soil-bound organisms often benefit because of increased bacteria populations due to natural fertilizer spread such as manure, while experiencing reduced intake of herbicides and pesticides commonly associated with conventional farming methods. [3]
Insects that pose disadvantages are considered pests. Some species can cause indirect damage by spreading diseases, and these are termed as disease vectors. Those that are beneficial include those that are reared for food such as honey, substances such as lac or pigments, and for their role in pollinating crops and controlling pests. [1]
Many weed species attract beneficial insects that improve soil qualities and forage on weed pests. [206] Soil-bound organisms often benefit because of increased bacteria populations due to natural fertilizer such as manure, while experiencing reduced intake of herbicides and pesticides. [201]
Beneficial insects can include predators (such as ladybugs) of pest insects, and pollinators (such as bees, which are an integral part of the growth cycle of many crops).). Increasingly certain species of insects are managed and used to intervene where natural pollination or biological control is insufficient, usually due to human disturbance of the balance of established ecosys
Record-keeping is essential, as is a thorough knowledge of target pest behavior and reproductive cycles. Since insects are cold-blooded, their physical development is dependent on area temperatures. Many insects have had their development cycles modeled in terms of degree-days. The degree days of an environment determines the optimal time for a ...
Within a guild each species of insect or plant provides a unique set of diverse services that work in harmony. Plants may be grown for food production, drawing nutrients from deep in the soil through tap roots, balancing nitrogen levels in the soil , for attracting beneficial insects to the garden, and repelling undesirable insects or pests.
Soil mesofauna do not have the ability to reshape the soil and, therefore, are forced to use the existing pore space in soil, cavities, or channels for locomotion. Soil Macrofauna, earthworms, termites, ants, and some insect larvae, can make the pore spaces and hence can change the soil porosity, [5] one aspect of soil morphology. Mesofauna ...
