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 ...

Mealybug
Mealybugs are insects in the family (biology), family Pseudococcidae, unarmored scale insects found in moist, warm habitats. Many species are considered pest (animal), pests as they feed on plant juices of greenhouse plants, house plants and subtropical trees and also act as a vector (epidemiology), vector for several plant diseases. Some ants live in symbiotic Ant#Relationships with other organisms, relationships with them, protecting them from predators and feeding off the Honeydew (secretion), honeydew which they excrete. Description Mealybugs are Sexual dimorphism, sexually dimorphic: females appear as nymphs, exhibiting reduced morphology, and lack wings, although unlike many female scale insects, they often retain legs and can move. Males are smaller, gnat-like and have wings. Since mealybugs (as well as all other Hemiptera) are hemimetabolous insects, they do not undergo complete metamorphosis in the true sense of the word. However, male mealybugs do exhibit a radical cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientists From Paris
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''
