Date palm hooper is one of the most important pests on date palms with many highly diverged populations varied in damaging rate and preferring host cultivar. Current and potential geographic distribution of date palm hopper, Ommatissus lybicus (de Bergevin; Hemiptera: Tropiduchidae) in Iran was modeled using the Maxent procedure. Point sampling data sets included latitude, longitude, and altitude and were augmented with data on 19 bioclimatic variables retrieved from WorldClim dataset for use as predictor variables in Maxent. Maxent results demonstrated that northwest Sistan-Baluchestan, east, south and southeast Kerman, northeast and northwest Hormozgan and small districts of Bushehr provinces are hot spot habitats for O. lybicus in Iran. Jackknife analysis revealed that precipitation of warmest quarter was the most influential explanatory variable in determining distribution of O. lybiucs in Iran. Moreover, curve response and frequency distribution analyses revealed that annual mean temperature was the most predictive factor of the distribution of O. lybicus. Discontinuity in predicted hot spot habitats of O. lybicus was consistent with the genetic structure recorded for this species. Our study represents valuable information that can inform pest management strategies aimed at preventing population expansion and niche shift.
