%X The effects were studied of incorporating three synthetic insect juvenile hormones and five analogues in flour diets for T. castaneum. The synthetic hormones used were: methyl 10,ll-epoxy-7-ethyl-3,ll-dimethyltrideca- 2,6-dienoate (compounds I and II; these had the same structure but consisted of different isomer ratios), and methyl cis-l0,11-epoxy-3,7,11-trimethyltrideca-trans-2,trans-6-dienoate (III). The analogues used were: 6',7'-epoxy-3',7'-dimethyloct-trans-2'-enyl 3,4-methylenedioxyphenyl ether (IV); 3'-methyl-7'-ethylnona-2',6'-dienyl 3,4-methylenedioxyphenyl ether (V); ethyl 3,7,11-trimethyldodeca-2,4-dienoate (VI); isopropyl 11-methoxy-3,7,11-trimethyldodeca-2,4-dienoate (VII); 6',7'-epoxy-3',7'-dimethyloct-trans-2'-enyl 4-ethylphenyl ether (VIII). Compounds II-VII were incorporated in flour media at concentrations of 5 and 20 p.p.m. and I and VIII at 5 p.p.m. only.   The number of eggs laid in various treated media did not differ significantly from that in the control. Egg to adult development was inhibited by VII and VIII at 5 p.p.m. and by II, IV and VI at 20 p.p.m. Development was completed in other treatments but with a high level of adult morphological deformity except with V and VI at 5 p.p.m. The compounds tended to increase the developmental period from egg to adult.
