The toxicity of acetamiprid was tested on Reticulitermes flaviceps (Oshima), Coptotermes formosanus Shiraki and Odontotermes formosanus (Shiraki), important pests in buildings, dams and trees in China. The LD50 Value of acetamiprid among worker termites of the three species was 4.41 x 10(-5), 13.8 x l0(-5) and 146 x l0(-5) mug/ter mite, respectively, at 72 hr post-treatment. More than 90% of individuals tested died within 120 hr of coming into contact with sandy soil containing 4.8 ppm of acetamiprid. A 10-cm thick barrier of loam treated with 8.0 ppm of acetamiprid retarded completely the penetration by C. formosanus and O. formosanus.
