Determination of the Components of the Boll Weevil Pheromone with a High Pressure Liquid Chromotographic Method

Abstract

A high pressure liquid chromatographic method was developed to separate the 4 components of the pheromone of the boll weevil. Minimum detectable amounts with 3.5% tetrahydrofuran in hexane was 10 ng for (+)-cis-2-isopropenyl-1-methyl-cyclobutaneethanol, 1 ng for (Z)-3,3-dimethyl-Δ¹,α-cyclohexaneethenol, and 2.5 ng each for (Z)-3,3-dimethyl-Δ¹,α-cyclohexaneacetaldehyde and (E)-3,3-dimethyl -Δ¹α-cyclohexaneacetaldehyde at 214 nm.
