Eucalypts, to somehow resistant against dryness, saltiness and adaptable to harsh and different climates are fast growing trees with medicinal, industrial and traditional applications. In this study resistance of heart wood of E. striaticalyx F.V.Muell was evaluated against termites attack in both treated and untreated conditions using protective materials of celcure and creosote in field test based on ASTM. 1990. D-1758 (Standard Method of Evaluating Wood preservatives by Field Test with Stakes). The experiment was carried out in Khoozestan province (Albaji station in Ahvaz). For this purpose, samples with dimensions of 2.5×2.5×2.5, 30×8×8 and 47×2×2 centimeters were prepared and saturated with creosote and 5 percent celcure. The damage of termites to E. striaticalyx control samples was ordinarily started after 3 years. The gradual damage was estimated as 70% after 9 years. Soft rot which supposedly facilitate the damage by termites were observed on all of the samples. The damage on wood samples treated with creosote and celcure was observed after six years, with the approximate amount of 25% after seven years.
