An investigation that lasted for two complete years was carried out in the laboratory of Economic Entomology Department, Faculty of Agriculture, Kafr El-Sheikh, Egypt. Thirteen materials were selected and were planned to represent spices: medical and aromatic plants, dried vegetables, dried fruits, peanut, date palm, garlic and romano cheese. The objectives of the present work were: 1) survey all pests infesting the chosen materials, 2) the population density of those organisms, through 2 years, 3) to find out correlation between R.H. and temp. on the population activities, 4) to find out the diversity of recorded species, 5) to study the effect of some toxicants for controlling pest infestation. Results revealed in recording 13 acari species of 8 families and 17 insect species of 11 families. Eight pest species were found to be dominant, they were Tyrophagus putrescentiae Sch. (15.22%), Cheyletus malaceensis, Oud. (14.5%), Acarus siro L. (9.91%), Haemolaeiapus casalis, Berlise (9.83%), Trogium pulsatorium, L. (8.85%), Glycophagus destructor Sch. (6.89%), Cleyletus eruditus Sch. (6.77%) and Stegobium panjceum L.(5%). The predominant species included 7 species; Rhizoglyphus spp., Caloglyphus beta, Attia, Cunaxa spp., Bdella spp.; Phlebotomus spp., Caryptolestes ferrugineus, Steph., and Tribolium confusum J. du. Val. The least category was the rare species constituted (2.36%) of the whole recorded species. Results also indicated that romano cheese was the most susceptible material with pests (94.11%) followed by dried fruits while the medical and aromatic plants, the least (10.61%). Populations fluctuated all time experiment. The diversity of the recorded species was clear.
