الملخص EN

A new crystal compound 2,5-diacetoxy-2-benzyl-4,4,6,6-tetramethyl-1,3-cyclohexanedione was isolated from the leaves of Syzygium lineare.

The insecticidal activity of the compound was assessed against fourth instar larvae of Spodoptera litura.

Its activity was better than the positive control azadirachtin.

The compound was responsible for growth inhibition on S.

litura.

It induced larval, pupal and adult deformities even at low concentration.

The compound may be useful as a botanical pesticide.
