Insects
Research News and Information
Definition of 'Insects'Insects are a class, Insecta, of Arthropoda whose members are characterized by division into three parts: head, thorax, and abdomen. They are the dominant group of animals on earth, several hundred thousand different kinds having been described. They have lived on earth for about 350 million years, as compared with less than 2 million for man. While insects are often commercially valuable and useful as scavengers, many species are harmful, causing enormous losses in agriculture and storage. Three orders, HEMIPTERA; DIPTERA; and Siphonaptera; are of medical interest in that they cause disease in man and animal.

Modeling three-dimensional morphological structures using spherical harmonics.
15 Oct 2009 
Quantifying morphological shape is a fundamental issue in evolutionary biology. Recent technological advances (e.g., confocal microscopy, laser scanning, computer tomography) have made the capture of detailed three-dimensional (3D) morphological ... Read more...
Common sense about taste: from mammals to insects.
14 Oct 2009 The sense of taste is a specialized chemosensory system dedicated to the evaluation of food and drink. Despite the fact that vertebrates and insects have independently evolved distinct anatomic and molecular pathways for taste sensation, there are ... Read more...
Efficacy of grain protectants against four psocid species on maize, rice and wheat.
29 Sep 2009 BACKGROUND: Psocids are emerging pests in stored products, particularly in amylaceous commodities such as grains. Currently, their control is based on the use of fumigants and contact insecticides; however, newer data indicate that psocids are ... Read more...
