Diabrotica Duplicata
''Diabrotica'' is a large, widespread genus of beetles in the family Chrysomelidae. Members of this genus include several destructive agricultural pest species, sometimes referred to as corn rootworms. There are an estimated 400 species grouped into the genus ''Diabrotica''. Within ''Diabrotica'' there are 3 series: f''ucata, virgifera,'' and ''signifera'' groups. The ''fucata'' series contains the majority of ''Diabrotica'' diversity with 354 species. ''Fucata'' are characterized as multivoltine, producing two broods of offspring per year. The ''virgifera'' series comprises 24 species, and the ''signifera'' series contains 11. Additionally, ''virgifera'' and ''signifera'' are characterized as univoltine, and will only brood one set of offspring annually. There is very limited information on most species of ''Diabrotica.'' Majority of the research conducted on the ''Diabrotica'' ''genus'' focuses on investigating species of consequential economic importance, such as ''D. balteat ...

Louis Alexandre Auguste Chevrolat
Louis Alexandre Auguste Chevrolat (29 March 1799, Paris – 16 December 1884, Paris) was a French entomologist. He specialized mainly on the beetles and was a founder of the Societe entomologique de France in 1832. Chevrolat worked as a toll administrator in government service in Paris. He was an amateur entomologist who studied mainly beetles and birds. He published nearly 250 notes and papers and was the Species description, author of more than 2,000 species. He was one of the founders of the Société entomologique de France in 1832. On his death, his collection was dispersed. Part of his collection is now in the Natural History Museum in London along with some manuscripts. Works (Selection) * 1833a. Description de Buprestis analis. ''Magasin de Zoologie'' 1833.

Steinernema Carpocapsae
''Steinernema carpocapsae'' is an entomopathogenic nematode and a member of the family Steinernematidae. It is a parasitic roundworm that has evolved an insect-killing symbiosis with bacteria, and kills its hosts within a few days of infection. This parasite releases its bacterial symbiont along with a variety of proteins into the host after infection, and together the bacteria and nematode overcome host immunity and kill the host quickly. As a consequence, ''S. carpocapsae'' has been widely adapted for use as a biological control agent in agriculture and pest control. ''S. carpocapsae'' is considered a generalist parasite and has been effectively used to control a variety of insects including: Webworms, cutworms, armyworms, girdlers, some weevils, and wood-borers. This species is an example of an "ambush" forager, standing on its tail in an upright position near the soil surface and attaching to passing hosts, even capable of jumping. As an ambush forager, ''S. carpocaps ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
