Preliminary study of insect attraction by a mixture of semiochemicals containing 1,2,4-trimethoxybenzene in domestic citric-culture

Abstract

In this work we describe a new efficient strategy for the preparation of 1,2,4-trim.ethoxybenzene (3) in 56% overall yield. The compound 3 was used in a preliminary study of insect attraction by a mixture of semiochemicals called TIV, composed of indol (1), vanillin (2) and 1,2,4-tiimethoxybenzene (3), in eight Mc Phail style traps installed at a domestic orchard of citric-culture, containing 120 trees not infected by plagues in Bom. Jesus Farm., located next to a patch of the Atlantic Forest, at Silva Jardim.,.
