Abstract

Field trials were conducted in the west-northern coast to evalu­ate the efficacy of several chemicals against the subterranean termite, Microcerotermes eugnathus in areas of vine and acacia trees at Fouka village. In the first test, dragnet and cidial proved to be highly effective for one year in vine area. Dimilin, copper sulphate and borax showed sig­nificant efficacy depending on the concentration used. At 2% concentra­tion, their efficacy reached 100, 97.47, 82.54, 86.68 and 81.23%, re­spectively_Also, chemicals in the second test indicated pronounced potency to this pest when applied under a concrete slab in comparison with uncovered treatments in vine area. Concentration 2% of cidiai, su­micidin and cyanox induced 100, 99_39 and 98.36% protection for one year with a concrete slab method, in comparison to 97.47, 99.04 and 94.6% with uncovered trenches. The third test demonstrated the highest effects of sodium fluo­ride, copper sulphate and borax at 5% concentration against hteugnathus in acacia tree area, giving above 90% protection after one year.
