Biology of Xanthogaleruca lateola and Study on different method for its control in Garmsar Region

In this study we examined biology of booh that eat leaft of elm with termed Xanthogaleruca lateola coleoptera, chrgsome lidae and also we studied method of control of that. It is perform in garmsar town ship. For this purpose carry out necessary sampling of several ages in period of this growth. Within condition of laboratory collected/ eaf branch possess category egg and piece. During test nursery dampen leaf is secure of spray of wateron them and put egg in anvcobator with temperature 24+2 and dampen 60+ and during period of light 15 hour, we examine state during period of germinal carry out and size depended to medicine in cludde length of medicine and width of capsule egg and etc. according to the result, width of capsule egy end etc. according to the result, winter sample and pass 15 day after farvardin(first month of the persion solar year) with temperature almost 17 thermometer centigrade appearance and begin lay and produce medicine. Then to end of sharivar(6 th month of the Persian solar year) leave 3 whole bungle. Egg observed form of category 4-1 row and in each row eggs was 1-40 between row. During period was 8 days.
