Trissolcus semistriatus is an egg parasitoid showing the crucial role in plant protection as biological control agents on Eurygaster integriceps under different climatic conditions. The geographical distribution of T. semistriatus was studied using Maximum Entropy (MaxEnt) in different climatic regions of Iran. Records of 1161 specimens collected from 24 climates, altitude and climate variable data were used for modeling analysis. The results show that northwestern of Iran with climatic characteristics of mild winters, warm summers and arid regime were the most suitable areas for T. semistriatus, while the central, western and southeastern parts with very high temperatures were predicted to be less suitable. The habitat distribution patterns for useful species such as T. semistriatus can be modeled using the small number of occurrence records and environmental variables which is important in plant protection and implementation of biological control programs.
