''Puto'' is a genus of insects described as giant mealybugs, although it is the only extant genus in different family Putoidae; it was originally described by Victor Antoine Signoret in 1875. Hosts Giant mealybugs occur on a wide range of hosts, each species having its own specific host. Host plants commonly include conifers, grasses and various woody shrubs.

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 insect Scale insects are small insects of the Order (biology), order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient g ...s). He established methods for the preparation of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
