Economic entomology is a field of entomology, which involves the study of insects that benefit or harm humans, domestic animals, and crops. Insects that pose disadvantages are considered pests . Some species can cause indirect damage by spreading diseases, and these are termed as disease vectors .
Encouraging beneficial insects, by providing suitable living conditions, is a pest control strategy, often used in organic farming, organic gardening or integrated pest management. Companies specializing in biological pest control sell many types of beneficial insects, particularly for use in enclosed areas, like greenhouses .
Many insects are ecologically beneficial as predators of pest insects, while a few provide direct economic benefit. Two species in particular are economically important and were domesticated many centuries ago: silkworms for silk and honey bees for honey. Insects are consumed as food in 80% of the world's nations, by people in roughly 3,000 ...
The Xerces Society calculates the economic impact of four ecological services rendered by insects: pollination, recreation (i.e. "the importance of bugs to hunting, fishing, and wildlife observation, including bird-watching"), dung burial, and pest control. The value has been estimated at $153 billion worldwide. [10]

Scientists remain uncertain about the existence and degree of pain in invertebrates, including insects.However, a recent review of the neurobiological and behavioral evidence consistent with the hypothesis of pain found strong evidence consistent with precautionary treatment in at least two orders of insects at the adult life stage (Blattodea and Diptera), ultimately considering evidence from ...
A giant water bug attacking a fish. Insect ecology is the interaction of insects, individually or as a community, with the surrounding environment or ecosystem. [1] This interaction is mostly mediated by the secretion and detection of chemicals (semiochemical) in the environment by insects. [2]
