Abstract

Twenty-seven compounds were screened in order to find an attractant inhibitor for male Grapholitha funebrana Tr., with the final goal of rendering the conventional sex attractant for male G. molesta Busck more species specific. The greatest inhibitory effect was observed with (Z)-6-dodecenyl acetate, which significantly decreased G. funebrana captures when added at 0.1% or more to the known attractant blend. This compound also inhibited G. molesta captures, but to a much lesser extent. At sites with high population density, 92% of all Grapholitha spp. caught were G. molesta with baits containing (Z)-6-dodecenyl acetate, and 67% with baits without this compound. Although G. molesta captures in traps with (Z)-6-dodecenyl acetate were about half of those in traps without, captures were still high enough to permit reliable monitoring of the occurrence of G. molesta. However, in commercial orchards, with much lower population densities, the addition of (Z)-6-dodecenyl acetate decreased captures of G. molesta to a level at which capture information was unreliable.
