Hazards is a knowledge of human beings. In the ecology of the planet, insects are stable, active, and almost all parts of the biosphere community, and the most diverse group of animals. This variety of biological and regional insects is associated with the geography of mountainous, plain, desert Land levels and qualitative changes in salty and sweet water have been regulated and have led to the active presence of insects in almost all large and small biological units. From the beginning of the advent and during the long evolution, geosciences and geosciences of the four geological periods have been stably restored and, due to their high adaptability, have the potential to blast the population in appropriate climatic conditions. The purpose of this research, which first addresses the issue of insects as a climate risk, is to explain the role and behavior of these organisms in causing many damage to the environment. In this connection, the study of the insect named "Cicadidae" which causes serious damage to the ecosystem, is studied. In the case of the city of Malayer, this study was studied in this connection and during the continuous studies. Field observations revealed that the activity and propagation of this crop are completely dependent on the climatic conditions of the environment and its dependent patters, such as temperature, evaporation, relative humidity, soil and climatic conditions within the soil.
