Entomology (entomology) Entomology is the scientific study of insects. Engaged in the study of insects, an entomologist who is called (entomologist). Entomologist of the insects throughout the world to observe, collect, feeding and testing, they conducted research covers the entire scope of the laws of biology, including evolution, ecology, behavior, morphology, physiology, biochemistry and genetics and so on. General characteristics of these studies is to study the organisms are insects. _Select_ion of insects as a research biologist material, from which opened a lot of the mystery of nature, the most prominent example is in Drosophila (drosophia melanogaster) as genetic material developed. Insects for the study of material advantages: easy to keep insects, life cycle is short, in a short time to obtain a large number of individuals; insects is an open cycle of animals, organs and endocrine glands of the transplant easier, invertebrates, many problems are physiological insects as experimental materials to study; insects like primates as research material vulnerable to social and moral constraints. In addition to basic research entomologist, insect growth and development of the law to reveal, but in many cases is mainly engaged in the prevention of harmful insects, research and utilization of beneficial insects. Entomologist's responsibility is to master the laws of nature, insect control, insect management, so that "no harm harmful, even beneficial interest." As human activities and scientific experiments, as well as the development of other basic disciplines and interdisciplinary cross-penetration phase of entomology has been described in the experimental stage to the stage of molecular biology, is moving in macro and micro aspects of development, in disciplinary development process, gradually formed their own Entomology many branches.

Entomology entomology Instars, each part of the ever-changing structure, the same structure (the modern form School concept) in different insects, shape, position can be varied, to To be treated as a different structure, give a different name, so name confusion So far the concept can not be unified by modern morphology together, which has become now Generation of taxonomy development, a major obstacle. Insect Physiology is the study of insects and their organ systems in vivo and group Organization of life and functional mechanism of discipline, on the one hand and cross-functional morphology Fork, the other side and ecology intersect; its content it must be determined An experimental science. Therefore, insect physiology is the only form of the 1930s Into an independent discipline, adapted to the needs of development of insect ecology; To 40 years, the development of synthetic pesticides and use, to stimulate the insects The rapid development of physiology, insect toxicology and subsequently derived. Pests Pathogenic microorganisms and the use of biological control, insect pathology have resulted in 40 years of formation. Insect toxicology and pathology are very state insect Insect physiology, insect physiology is the science related to the application's main To the field. Study insect physiology experiments require sophisticated instruments, such as interest Cellular level using electron microscopy studies, the use of bio-physical and Biochemical methods for molecular studies. Of Insect Physiology Complexity, but also in many species of insects, lifestyle and adapt to Sexual differentiation of the diversity of insects on one or several of the findings May not be applicable to other insects. To date, widely used in physiology research Study of insects less than 20, or whichever body large (eg, enjoys a spider), or whichever is easy to In feeding (such as powder A), or whichever economic importance (such as bees, silkworm), Or whichever is the test of applicability (such as genetic research with fruit flies, houseflies research with Toxicology studies, endocrinology studies with blood-sucking dragonfly), and so on, but not enough to On behalf of the whole picture of insects. On the physiology content, is far from comprehensive exhibition Open; studied more thoroughly are: ① the epidermis and molting, metamorphosis and shock Su control; ② the enzymatic mechanism of action as the core of pesticides; ③ the subject of Feed the needs of development work undertaken to stimulate the study of nutrition. Even if this Some areas are still many mysteries, whether in theory or from the application View, the development potential of Insect Physiology are great. Insects, insect ecology and the environment (organic and inorganic) The relationship between the disciplines, including insect habitats and adaptive behavior research Study. Any expression of bio-genetic characteristics in varying degrees by Environmental conditions, so the ecology and physiology are closely bound together System, and its focus in addressing the relationship with the environment, population dynamics and to Geographical distribution and other issues. Insect ecology as an experimental science, its development is almost With the same period of insect physiology, and to study both "functional." But Physiology in cells, tissues, organs and individual level studies, and Laboratory-based; ecology in individuals, groups, local populations, health Materials community, different levels of ecosystem research to field work Based. Environment includes many factors, therefore, in addition to involving students of ecology Science, but also involves genetics, biochemistry, morphology, behavior, Pathology, geography, paleontology, meteorology and soil science and other disciplines, To form a different branch of ecology. Especially the emergence of the 1980s Insect chemical ecology, and is considered the most comprehensive ecology. 1960s in harm
