Abstract:The highly active juvenile hormone mimic JH-25 (7-ethoxy-1. (P-ethylphenoxy) -3,7-dimethyl-2-octene) was incorporated into bleached flour at rates of 1 to 5 ppm, and the flour was then aged. No normal adults emerged from samples of the flour exposed periodically to Tribolium castaneum (Herbst) throughout the 400-day test. Chemical analyses of an extract of the flour by liquid chromatography with UV detection and bioassays of the extract against Tenebrio molitor L. showed that ca. ½ the JH-25 remained in the flour spiked with 1 ppm JH-25 after aging 1 year.
