He wrote ''Détermination précise des insectes nuisibles, mentionnés dans les différents traités relatifs à la culture des arbres fruitiers, et indications des moyens à employer pour s'opposer à leurs ravages'' (1827) He described the predatory gall midge ''Feltiella acarisuga ''Feltiella acarisuga'' is a species of predatory gall midge Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths ...''. References Gaedike, R.; Groll, E.

Dijon (, , ) (dated) * it, Digione * la, Diviō or * lmo, Digion is the prefecture of the Côte-d'Or department and of the Bourgogne-Franche-Comté region in northeastern France. the commune had a population of 156,920.

Entomologist
Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. They have many kinds of intera ...

Feltiella Acarisuga
''Feltiella acarisuga'' is a species of predatory gall midges which will feed on various species of spider mite Spider mites are members of the Tetranychidae family, which includes about 1,200 species. They are part of the subclass Acari (mites). Spider mites generally live on the undersides of leaves of plants, where they may spin protective silk webs, a ...s. It is especially common when spider mites occur in colonies. It requires a high spider mite density and high humidities to become established. Mode of action Adult gall-midges search for spider mite colonies actively and deposit eggs next to the spider mites. The larvae that hatch feed on spider mite eggs and suck them empty. It takes one week for the eggs to develop to mature larvae. The pupal stage takes approximately one week. Spider mites that are killed by the gall-midge shrivel up and become brown or black. Dozens of larvae can be found per spider mite infested leaf. White cocoons can be visible along the veins of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
