[A parasitological study of cockroaches (Blattidae)]

All kinds of arthropoda can find a suitable environment to grow and spread in this country because of its mild and subtropical climate. Arthropods are harmful to men, animals and plants in many ways. The most important role the arthropods play is in carrying germs and parasites. Cockroaches are widely spread in Turkey, they transmit bacteria, viruses, protozoa and helminths mechanically and biologically. Because of their close contact with human beings, these insects encouraged us to make parasitological investigations. In the hindgut of cockroaches we found three nemethod species; Suifunema caudelli, Galebia aegyptiaca, and Hammerschmidtiella diesingi.
