Survey studies were conducted on rat species in three different sites at Sharkia governorate (i.e. houses, citrus farm and granaries). Results revealed that there are six rat species and sub species belonging to family Muridae Order Rodentia. These species were: the field rat or the Nile grass rat, (Arivcanthis niloticus); the Norway rat or brown rat (Rattus norvegicus); The house mouse, (Mus musculus) and sub species were the gray bellied rat, (Rattus rattus akxandrinus); the white bellied rat, (Rattus rattus frugivorus); and the Black rat, (Rattus rattus rattus). The highest distribution percentages was 71.4% for R. norvegicus in granaries, while the Nile grass rat, A. niloticus was not record at the same place. The highest sex ratio was (3 ♂: 0 ♀) for A. niloticus in citrus farm compared with other rat species whereas the least was (1♂: 1♀) for R. r. alexandrinus and R. rattus frugivorus in citrus fam and granaries, respectively. Regarding granaries citrus farm and houses, females were recorded with highest percentages (66.6, 66.6, 55.6 and 55.6%) for R. rattus rattus, R. r. frugivorus, R. norvegicus and M. musculus, respectively. The tail length of male R. rattus frugivorus was the longest tail for all rat species. As for the mean body weight of females R. norvegicus, was the highest (348.75 ± 21.75 gm, 305.0 ± 12.91 gm and 285.0 ± 20.82 gm) in citrus farm, houses and granaries, respectively. On the other hand, the highest weight for males were 336.25 ± 17.97gm, 330.0 ± 34.64 gm and 285.0±11.23 gm in granaries, houses and citrus farm, respectively. The highest length head with body, rat male R. norvegicus at the three tested habitats. The highest infestation of ectoparasites was recorded on male, R. norvegicus in houses (48.75 ± 26.39 /rat). These ectoparasities were lice, mites and fleas.
