The effect of some chemical and mechanical treatments on the reduction of the fig root borer Batocera rufomaculata was evaluated on fig trees in North Sinai Governorate during 1993-1995 seasons. Results obtained showed that injecting the larval tunnels with 5 ml. Cidial L SO/ liter kerosene, kerosene alone and gasoline gave good results. Painting the trunks with Stemex, Kerosene + Cidial L 50 (5 ml./liter), Kerosene, Lime, and Waste oil prevent the adults from attacking fig trees. The first two materials gave the highest results on reduction of egg deposition. Crushing the eggs had clear effect on the protection of fig trees com­pared with the untreated ones. Also, surrounding the trees with mosqui­to net had effective role on preventing the adult females from laying their eggs on the trees.
