Investigation of some environmental parameters effect on incidence and distribution of Nezara viridula L. and Acrosternum millieri in Yazd provine of Iran using Maximum Entropy modeling

Recognition of environmental factors and variables affecting the incidence and distribution of insect pests has always been considered by researchers as one of the strategic aims of pest control. Nezara viridula L. and Acrosternum millieri Mulsant & Rey. have been introduced recently as one of the most important pests of pistachio and almond products in the Yazd province of Iran. In this study, the effect of environmental variables on the presence and distribution of these species was performed using the maximum entropy method. The results of the Jacknife test for N. viridula showed that the variables of altitude and maximum temperature of the warmest month have the maximum effect on incidence and distribution when used separately.Finally, by observing the maps obtained from the species distribution model, "vegetation" for N. viridula and "altitude" for A. millieri were suggested as critical climatic factors in the presence and distribution of the studied species.
