Chrysolina Hongyuanensis

picture info	Chrysolina Hongyuanensis ''Chrysolina'' is a large genus of leaf beetles in the subfamily Chrysomelinae. Most species are distributed in Europe, Asia and Africa with a small number of species inhabiting North America (including introduced European ones) and introduced species in Australia. The species ''Chrysolina cerealis'' and '' C. graminis'' are protected in the United Kingdom. All species of ''Chrysolina'' are phytophagous, feeding on specific food plants, and some of them have been used for biological control of weeds. To control ''Hypericum perforatum'' (St John's wort), ''C. hyperici'' was successfully naturalized in Australia in the 1930sWilfred William Robbins, Alden Springer Crafts.

picture info	Biological Control Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
