The cyst nematodes Heterodera and Globodera species in Egypt

Abstract

A survey was conducted in three governorates Alexandria, El Behera and Sohag of Egypt during 2012-2016 and one hundred seventy-eight soil and root samples were collected for the detection of cyst nematodes. The results showed the prevalence of nine cyst nematode species associated with different crop plants: Heterodera avenae on wheat, H. daverti and H. trifolii on Egyptian clover, H. leuceilyma on Bermuda grass, H. lespedezae on lentil, H. goldeni on qasabagrass, H. schachtii on cabbage and sugar beet, H. zeae on corn and wheat and Globodera rostochiensis on potato. The cyst nematodes H. leuceilyma and G. rostochiensis are new records of the country and H. lespedezae on lentil is a new host plant record in Egypt.
