William Harris Ashmead
William Harris Ashmead was an American entomologist born on 19 September 1855 at Philadelphia. He died 17 October 1908 at Washington D.C. After his studies in Philadelphia, Ashmead worked for the publisher J. B. Lippincott & Co. Later, he settled in Florida where he formed his own publishing house devoted to agriculture. He also launched the '' Florida Dispatch'', an agricultural weekly magazine which included a headed section devoted to injurious insects. In 1879, he began writing papers for scientific publications and, in 1887, he became a field entomologist working for the Ministry for the Agriculture of Florida. The following year, he became entomologist at the Agricultural Research station of Lake City. In 1889, he worked again for the Ministry for Agriculture. The following year, and for two years, he traveled, in particular to Germany, to perfect his entomological knowledge. In 1895, he obtained the post of conservation assistant in the Department of Entomology of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexandre Arsène Girault
Alexandre Arsène Girault ( ; 9 January 1884 – 2 May 1941) was an American entomologist specializing in the study of chalcid wasps. An eccentric and controversial figure, Girault was also a prolific and dedicated entomologist. He published more than 325 papers and described over 3000 new taxa from Australia. Biography Alexandre Arsène Girault was born in Annapolis, Maryland, on January 9, 1884, to Joseph Bonaparte Girault and Elizabeth Frances Girault (née Goodwin). He is named after his grandfather, Arsène Napoleon Alexandre Girault de Saint Fargeau, one of the founding faculty of the US Naval Academy. Girault earned his Bachelor of Science degree from the Virginia Polytechnic Institute and State University in 1903. From 1904 to 1907 he was employed as a field assistant for the United States Bureau of Entomology. During this time, he was involved in research on plum curculios (''Conotrachelus nenuphar''), Colorado potato beetles (''Leptinotarsa decemlineata''), and Ame ...

Ricardo García Mercet
Ricardo García Mercet (16 August 1860 – 12 May 1933 was a Spanish naturalist and entomologist. He was a pharmacist attached to the Spanish military. At various times he was a member of the Spanish Royal Academy of Sciences, President of Sociedad Española de Historia Natural (Spanish society of Natural history); Secretary general of Asociación Española para el Progreso de las Ciencias (Spanish Association for the progress of science) and an Honorary Member of the entomological societies of Egypt and Chile. His collections of Chalcidoidea are conserved in Museo Nacional de Ciencias Naturales in Madrid and the Natural History Museum of Giacomo Doria The Museo Civico di Storia Naturale Giacomo Doria is a natural history museum in Genoa, northern Italy.

Chalcid Wasp
Chalcid wasps (, , for their metallic colour) are insects within the superfamily Chalcidoidea, part of the order Hymenoptera. The superfamily contains some 22,500 known species, and an estimated total diversity of more than 500,000 species, meaning the vast majority have yet to be discovered and described. The name "chalcid" is often confused with the name "chalcidid", though the latter refers strictly to one constituent family, the Chalcididae, rather than the superfamily as a whole; accordingly, most recent publications (e.g.,) use the name "chalcidoid" when referring to members of the superfamily. Most chalcid wasps are parasitoids of other insects, though other life styles are known, with the herbivorous fig wasps acting as pollinators. Various species are used as biological pest control agents or in scientific research. Description Chalcidoids are generally small wasps, averaging 1.5 mm in length and usually being less than 3 mm. The body is often metallic in colour. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...
