Victor Antoine Signoret
Victor Antoine Signoret (6 April 1816, Paris – 3 April 1889, Paris) was a French pharmacologist, physician and entomologist. In 1845 Signoret gained his doctorate in pharmacology at the University of Paris. His thesis was entitled ''De l'Arsenic considéré sous ses divers points de vue''. Pharmacology made him a wealthy man and he made many collecting trips mainly in Europe but also in Asia Minor. His very important collection is in the Naturhistorisches Museum, Vienna, Austria although there is significant material in La Specola museum in Florence. Signoret worked on Hemiptera, and is considered to be one of the first great students of Coccoidea (mealybugs and scale insects). He established methods for the preparation of slides for the examination of mealybug morphology. He wrote over 80 papers, including a ''Revision du groupe des Cydnides'' (1881–1884) and he was a Member of the Entomological Society of France Entomology () is the scientific study of insec ...

Hyalesthes
''Hyalesthes'' is a planthopper genus in the family Cixiidae. Nomenclature The etymology is from Greek: ὕαλος (glassy, hyaline) + ἑσθὴς (cloth, toga, robe). While Signoret originally treated the genus as masculine, as did many subsequent authors, according to the ICZN Art. 30.1.2, the name is feminine.

Black Wood Of Grapevine
"''Candidatus'' Phytoplasma solani" is a phytopathogenic bacterial '' Phytoplasma'' species of the 16SrXII group, the causal agent of the black wood of grapevine. The black wood of grapevine disease is classified as part of the grapevine yellows. "''Ca.''

Insect Vectors Of Plant Pathogens
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
