Abstract
Synthetically prepared pheromone compositions, prepared from various mixtures of (Z)-3,3-dimethyl-.DELTA..sup.1,.beta. -cyclohexane ethanol, (E)-3,3-dimethyl .DELTA..sup.1,.beta. -cyclohexane ethanol, (Z)-3,3-dimethyl-.DELTA..sup.1,.alpha. -cyclohexane acetaldehyde, (E)-3,3-dimethyl-.DELTA..sup.1,.alpha. -cyclohexane acetaldehyde, (E)-3,7-dimethyl-2,6-octadienoic acid, and (E)-3,7-dimethyl-2,6-octadien-1-ol were found to be attractive to both male and female pepper weevils. The compositions will greatly enhance pepper growers' ability to control these destructive pests.
