A. Sattar, A. Khan, N. Khatoon, A. Mujahid

Current study was carried out in December, 2014 to investigate the occurrence of helminth parasites in catfish species belonging to family Ariidae (Blecker, 1862). Four species of catfishes namely Arius arius (Hamilton, 1822), Arius caelatus (Valenciennes, 184…

Interactions of Heterodera daverti, H. goldeni and H. zeae with Meloidogyne incognita on rice

I. K. A. Ibrahim, M. A. EL-Saedy, S. F. A. Awd-Allah, Z. A. Handoo

The interactions of the cyst nematodes Heterodera daverti, H. goldeni and H. zeae with the root-knot nematode Meloidogyne incognita on rice (Oryza sativa) cultivars 'Giza 178' and Sakha 101' were studied in the greenhouse. Inoculation with H. goldeni alone or…
