Sirex Pygmaeus
''Sirex'' is a genus of sawfly in the family Siricidae, the horntails or wood wasps. Their bodies are black with a dark blue or green metallic reflection with some species having reddish-brown portions. They inject eggs with fungal endosymbionts into wood. The larvae of ''Sirex'' are unable to digest the wood on their own and rely on the fungus for nutrition, either eating the fungus or wood partially digested by the fungus. Female ''Sirex'' have a mycangium which is used to carry arthrospores of the fungus. The genus includes economically important pests; ''S. noctilio'', known simply as the 'Sirex woodwasp' is an invasive species, having spread widely across the world from its original range.Hurley, B.

Sirex Noctilio
''Sirex noctilio'', known as the Midnight woodwasp, European woodwasp, European horntail woodwasp, or sirex woodwasp, is a species of horntail, woodwasp, native to Europe, Asia, and northern Africa.New York State Department of Environmental Conservation, Copyright © 2011. Sirex Woodwasp – ''Sirex noctilio''. http://www.dec.ny.gov/animals/7248.html Adults vary in length from . This woodwasp is an invasive species in many parts of the world, including Australia, New Zealand, North America, South America, and South Africa, where it has become a significant economic pest of pine trees. The wasp can attack a wide variety of pine species, although some species seem to be more susceptible than others, and stressed trees often are attacked. During oviposition, the female wasp lays two eggs with or without a mucoid connective tissue, mucoid substance and a symbiosis, symbiotic fungus for the larvae to feed on once they hatch. The mucoid substance is toxic to trees and aids in tree d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
