Abstract
This research aims to identify beetle fauna active in the date stores of Iran's date-growing provinces, the geographical distribution of their ecological nest potential, and the exploitation of date stores in six important date-growing provinces of Iran, including Kerman, Fars, Khuzestan, Sistan and Balochistan, Bushehr and Hormozgan were done in 2023. Factor analysis was used to identify unobservable combined factors affecting the type of population distribution, cluster analysis method and accuracy of a clustering of the studied provinces, linear diagnostic analysis, and generalization of Fisher's linear discriminant. In date-growing areas of Iran, seven species of beetles were active, including Oryzaephilus surinaemensis, Oryzaephilus Mercator, Tribolium castaneum, Tribolium confusum, Carpophilus hemipterus, Carpophilus mutilatus, and Togoderma ganarium. This beetle had the most widespread presence in (Kerman, Fars, and Bushehr), (Kerman and Sistan and Baluchistan), (Khuzestan and Sistan and Baluchistan), Bushehr and Fars, respectively. The highest relative establishment rate was related to O. surinaemensis and in Kerman, Fars, and Bushehr provinces. The largest unexploited habitat niche was in Hormozgan province and was related to T. ganarium species in Khuzestan and Bushehr provinces. The higher the index of the unexploited habitat niche, the higher the probability of an unexpected flood of that hardy in the stores in that province. The potential distribution of pests is a crucial factor in determining the effects of global change on horticultural ecosystems.
