These experiments were carried out under field conditions on Coriander (Coriandrum sativum L.) plants along two seasons (2020–2021) and (2021–2022). Coriander seeds were sown at El-Qanater Research Station Farm in Qalubiya Governorate, as well as at a private farm in Menoufia Governorate, Egypt. The obtained results revealed the presence of 12 insect species belonging to order Hemiptera (Bemisia tabaci, Hyadaphis coriandri, and Myzus persicae), in addition to order Coleoptera (Stegobium paniceum, Lasioderma serricorne, Anthrenus verbasci, Trogoderma granarium, Callosobruchus maculatus, Acanthoscelides obtectus, and Rhyzopertha dominica), order Thysanoptera (Thrips palmi, and Tetranychus urticae). As well as the survey, it shows the existence of two parasites (Lysiphlebus testaceipes & Laelius pedatus) and five predators (Coccinella undecimpunctata, Hippodamia spp., Hippodamia variegata, Tenebriodes sp., 
and Thaneroclerus sp.) in addition to Phytoseiulus sp. as a predatory mite. Whiteflies, aphids, thrips, and two-spotted spider mites attacked coriander plants in the field during two seasons in two governorates. The highest numbers were recorded with aphid insects, followed by white flies, and there were no insect infestations during March between the two seasons. The coefficient of correlation between mean temperature and recorded insects was found to be positive, while it was negative for mean relative humidity. Many stored insect visitors, attacked the coriander plants especially at flowering and fertilization periods, such as A. verbasci, S. paniceum, L. serricorne, C. maculatus, and A. obtectus. It was noticed that all insect species infesting coriander plants always start with a few numbers, then gradually increase, reaching the highest numbers when the crop is dry. Results recorded that the insect species S. paniceum, L. serricorne, C. maculatus, T. granarium, R. dominica, and T. castaneum attacked coriander crops at stores along the two storage periods. The correlation between the carpet beetle, Anthrenus verbasci; the drug store beetle, Stegobium paniceum; the cigarette beetle, Lasioderma serricorne, cowpea beetle, Callosobruchus maculatus, the kidney bean beetle, Acanthoscelides obtectus, and minimum and maximum temperatures, relative humidity, and rainfall as abiotic factors was determined.
