The Journal of Economic Entomology , published by the Entomological Society of America , described itself in as the "most-cited entomological journal". In the 18th century many works were published on agriculture. Many contained accounts of pest insects. In France Claude Sionnest — was a notable figure. In Britain, John Curtis wrote the influential treatise Farm Insects , dealing with the insect pests of corn, roots, grass and stored grain.
It was not until the last quarter of the 19th century that any real advance was made in the study of economic entomology. Among the early writings, besides the book of Curtis, there was a publication by Pohl and Kollar, entitled Insects Injurious to Gardeners, Foresters and Farmers , published in , and Taschenberg's Praktische Insecktenkunde. It became a standard text worldwide. Among the most important reports early in the 20th century were those of Charles Valentine Riley , published by the U.
Department of Agriculture , extending from to his death, in which is embodied an enormous amount of valuable material. Department of Agriculture. The chief writings of J. Lintner extend from to , in yearly parts, under the title of Reports on the Injurious Insects of the State of New York. In France Alfred Balachowsky was a key figure.
In the last quarter of the 20th century new techniques were pioneered and new theories developed, for instance Integrated Pest Management by Ray F. Insects considered pests of some sort occur among all major living orders with the exception of Ephemeroptera mayflies , Odonata , Plecoptera stoneflies , Embioptera webspinners , Trichoptera caddisflies , Neuroptera in the broad sense , and Mecoptera also, the tiny groups Zoraptera , Grylloblattodea , and Mantophasmatodea.
Sustainable Entomology: How Insect Scientists Can Protect Our Planet
Conversely, of course, essentially all insect orders primarily have members which are beneficial, in some respects, with the exception of Phthiraptera lice , Siphonaptera fleas , and Strepsiptera , the three orders whose members are exclusively parasitic. Insects are considered pests for a variety of reasons, including direct damage by feeding on crop plants in the field or by infesting stored products, indirect damage by spreading viral diseases of crop plants especially by sucking insects such as leafhoppers , spreading disease among humans and livestock, and annoyance to humans. Examples of insects regarded as pests include the phylloxera , migratory locusts , the Colorado potato beetle , the boll weevil , Japanese beetle , aphids , mosquitoes , cockroaches , the Western corn rootworm , and some fly species.
In the past entomologists working on pest insects attempted to eradicate species. This rarely worked except in islands or controlled environments and raised ethical issues. Over time the language changed to terms like control and management. The indiscriminate use of toxic and persistent chemicals and the resurgence of pests in the history of cotton growing in the US has been particularly well studied.

Honey is perhaps the most economically valuable product from insects. Beekeeping is a commercial enterprise in most parts of the world and many forest tribes have been dependent on honey as a major source of nutrition. Honeybees can also act as pollinators of crop species.
Many predators and parasitoid insects are encouraged and augmented in modern agriculture. Silk is extracted from both reared caterpillars as well as from the wild producing wild silk. Sericulture deals with the techniques for efficient silkworm rearing and silk production. Although new fabric materials have substituted silk in many applications, it continues to be the material of choice for surgical sutures.
