Mesocyclops Leukarti
''Mesocyclops'' is a genus of copepod crustaceans in the family (biology), family Cyclopidae. Because the various species of ''Mesocyclops'' are known to prey on mosquito larvae, it is used as a nontoxic and inexpensive form of biological mosquito control. Biological control Individuals of ''Mesocyclops'' can be easily harvested, bred and released into freshwater containers where the ''Aedes aegypti'' mosquito larvae (the vector of Dengue fever) live. A big advantage of the ''Mesocyclops'' is that it is possible to teach schoolchildren how to recognize and collect them so that communities are able to perform sustainable mosquito control without much professional or governmental assistance. A field trial in Vietnam has shown that large-scale elimination of ''Aedes aegypti'' larvae is possible. Because ''Mesocyclops'' is a host for the parasitic round worm Guinea worm (''Dracunculus medinensis'', the causative agent of dracunculiasis), this method is potentially hazardous in the ...

Georg Ossian Sars
Prof Georg Ossian Sars HFRSE (20 April 1837 – 9 April 1927) was a Norwegian marine and freshwater biologist. Life Georg Ossian Sars was born on 20 April 1837 in Kinn, Norway (now part of Flora), the son of Pastor Michael Sars and Maren Sars; the historian Ernst Sars was his elder brother, and the singer Eva Nansen was his younger sister.Google Translate He grew up in Manger, Hordaland, where his father was the local priest. He studied from 1852 to 1854 at Bergen Cathedral School, from 1854 at Christiania Cathedral School, and joined the university at Christiana (now the University of Oslo) in 1857. He indulged his interest in natural history while studying medicine; having collected water fleas in local lakes with Wilhelm Lilljeborg's works, he discovered new species, and this resulted in his first scientific publication. Georg Ossian Sars had a good memory and excellent drawing skills, and illustrated some of his father's zoological works. Sars was a founding investig ...
