ABSTRACT:
A composition for attracting male pink hibiscus mealybugs which contains a carrier material or carrier and effective amount of (R)-lavandulyl (S)-2-methylbutanoate and (R)-maconelliyl (S)-2-methylbutanoate. Also a method for attracting male pink hibiscus mealybugs to an object or area, which method involves treating said object or area with effective amount of (R)-lavandulyl (S)-2-methylbutanoate and (R)-maconelliyl (S)-2-methylbutanoate. Cyclobutanes, 2,2-dimethyl-3-(1-methylethylidene)cyclobutanes, having the formula:wherein R1is hydrogen, a C1-11straight or branched alcohol, aldehyde, alkyl, ether (e.g. methanol, ethanal, 4-methylhexane, heptyloxymethane), or esters thereof with a C1-10saturated or unsaturated, straight or branched acid (e.g., formic acid, acetic acid, 2-methylbutyric acid, 3-methyl-2-butenoic acid) and R2is hydrogen, methyl, C1-10saturated or unsaturated, straight or branched alkyl (e.g. hexane, isopropenyl, 4-methyl-4-pentene). A method of disrupting male pink hibiscus mealybug mating with female pink hibiscus mealybugs, involving exposing a pink hibiscus mealybug population to a composition containing a pink hibiscus mealybug mating disrupting effective amount of (R)-lavandulyl (S)-2-methylbutanoate and (R)-maconelliyl (S)-2-methylbutanoate, and optionally a carrier material or carrier.
