Abstract

Field experiments were carried out at Etay El-Baroud Agric. Res. Station Farm (El-Beheira Governorate) during two successive wheat seasons (2010/11 and 2011/12) to study the relative susceptibility of some wheat cultivars to infestation with cereal aphids and glassy clover snails. The results revealed that, three cultivars; Misr 2, Giza 168 and Gemmeiza 7 had the least infestation by cereal aphids (37.3, 62.2 and 65.2 aphids/10 plants, respectively). On the other hand, three cultivars; Misr 2, Giza 168 and Gemmeiza 11 had the least infestation by glassy clover snails (5.6, 6.0 and 9.4 snails / 50x50 cm², respectively). Finally, two cultivars Misr 2 and Giza 168 proved the least infestation by cereal aphids and glassy clover snails.
