ECONOMIC ENTOMOLOGY, the name given to the study of insects based on their relation to man, his domestic animals and his crops, and, in the case of those that are injurious, of the practical methods by which they can be prevented from doing harm, or be destroyed when present.
At the Cape excellent works and papers are prepared and issued by the government entomologist, Dr Lounsbury, under the auspices of the Agricultural Department; while from India we have Cotes's Notes on Economic Entomology, published by the Indian Museum in 1888, and other works, especially on tea pests.
Of special importance in the history of systematic entomology was the scheme of F.

Macleay indeed never pretended to a high position in this branch of science, his tastes lying in the direction of Entomology; but few of their countrymen knew more of birds than did Swainson and Vigors; and, while the latter, as editor for many years of the Zoological Journal, and the first secretary of the Zoological Society, has especial claims to the regard of all zoologists, so the former's indefatigable pursuit of Natural History, and conscientious labour in its behalf-among other ways by means of his graceful pencil-deserve to be remembered as a set-off against the injury he unwittingly caused.
The foundations of modern entomology were laid by a series of wonderful memoirs on anatomy and development published in the 17th and 18th centuries.
His only unfortunate contribution to entomology - indeed to zoology generally - was his theory of pre-formation, which taught the presence within the egg of a perfectly formed but miniature adult.
Societies for the discussion and publication of papers on entomology were naturally established as the number of students increased.
Few branches of zoology have been more valuable as a meetingground for professional and amateur naturalists than entomology, and not seldom has the amateur - as in the case of Westwood - developed into a professor.
Though Riley was especially interested in the bearings of insect life on agriculture and industry - economic entomology (q.
After the publication of C. Darwin's Origin of Species (1859) a fresh impetus was given to entomology as to all branches of zoology, and it became generally recognized that insects form a group convenient and hopeful for the elucidation of certain problems of animal evolution.
Useful information on this point will be found in Ronalds's Fly-Fisher's Entomology, edited by Westwood.
The entomology of the island, however, is very rich, particularly in respect of Lepidoptera.

The museum, in the old East India Company's house, has fine collections in natural history, entomology, botany, anatomy, archaeology and ethnography, a picture and sculpture gallery, and exhibits of coins and industrial art.
The term labrum is used in zoology, of a lip or lip-like part; in entomology it is applied specifically to the upper lip of an insect, the lower lip being termed labium.
Thus the reflection of a person in a mirror is known as his "image"; in popular usage one person is similarly described as "the very image" of another; so in entomology the term is applied in its Latin form imago to an insect which, having passed through its larval stages, has achieved its full typical development.
