Pine processionary Pine processionary The pine processionary ("Thaumetopoea pityocampa") is a moth of the family Thaumetopoeidae. Sometimes placed in the genus "Traumatocampa", it is one of the most destructive species to pines and cedars in Central Asia, North Africa and the countries of southern Europe. The urticating hairs of the caterpillar larvae cause harmful reactions in humans and other mammals. The species is notable for the behaviour of its caterpillars, which overwinter in tent-like nests high in pine trees, and which proceed through the woods in nose-to-tail columns, protected by their severely irritating hairs, as described by the French entomologist Jean-Henri Fabre.
Canadian Science Centre for Human and Animal Health the only facility in Canada operating Containment Level 4 (CL4) laboratories and is believed to be the first in the world to have both human and animal Level 4 laboratories under one roof. Level 4 laboratories are designed to allow scientists to safely handle the most serious infectious agents. Their design, construction, and engineering controls safeguard against the release of any infectious material. Both NML and NCFAD operate critical diagnostic testing programs relied on across the country. These programs protect human health, animal health, and international trade. Staff also undertake cutting-edge research to advance scientific knowledge, improve diagnostics and develop
