Two insect growth regulators of the juvenile hormone type, namely 6,7‐epoxy‐3‐ethyl‐(p‐ethylphenoxy)‐7‐methylnonane, cis/trans mixture (compound A) and 6,7‐epoxy‐3,7‐dimethyl‐1‐[3,4‐(methylendioxy)‐phenoxy]‐2‐nonene (compound B) have been tested for their persistence when treated on stored grain. The interim results of this trial showed inhibition of adult emergence of Ephestia kühniella Zell., Plodia interpunctella Hübn., Tribolium castaneum Herbst and Rhyzopertha dominica F. even 8 months after treatment. The gas‐chromatography residue determination of compound A showed a reduction of 27 % of the original concentration within 8 months. No effect of compound A on the endosperm of the grain or taste of flour and bread could be found in the Bakery School in Lucerne.
