Insect Attractants

Insect attractants, chemicals that attract insects to traps, are used in many of the same ways as insect pheromones. The attractants are usually substances that lead the insects to food. A simple example is the use of narrow-necked bottles containing fruit juice or beer to trap wasps. The volatile fatty acid esters in the beer or fruit juice attract the wasps to the trap. Trimedlure, a mixture of isomers of the isobutyl esters of chloromethylcyclohexane carboxylic acid, was used successfully in eliminating Mediterranean fruit flies from Florida by attracting them to insecticide-containing traps. An improved version of this attractant in which the chloro groups are replaced with iodo groups has been developed.
