Summary:Three series of novel 1,5-diphenyl-l-pentanone derivatives were designed and synthesized. Their structures were characterized by IR, IH NMR techniques, and elemental analysis. The insecticidal activities of the new compounds were preliminarily evaluated. The bioassay results indicated that the compounds Xll--X30 displayed better aphicidal activity against Aphis gossypii than compounds X1--X10 and the lead compound （E）-l,5-diphenyl-1- penten-1-one （A）. The inhibitory rates of compounds X6 and X29 were 100% against Plutella xylostella （L.） at 600 mgoL 1. Compounds X12, X13, X19, X24, X25, X26 and X27 showed higher insecticidal activity against Tetranychus cinnabarinus （Boisduval） at 600 mgoL 1 than the lead compound （A）. Keywords Stellera chamaejasme L, （E）-l,5-diphenyl-l-penten-l-one, analogue, synthesis, design, insecticidal activity
