Nematodes were identified using several morphological diagnostic characters of the genus (male spicule(More)
97 Because of globalization and removal of geographical barriers, frequent biological invasions of introduced species become an urgent environmental problem. According to the Convention on Biological Diversity (CBD), precise identification of dangerous aggressive species at the early stages of their invasion to new regions is the most important component of(More)
