SPLAT-OFM A&K (ISCA Technologies, Inc. Riverside CA, U.S.A.), a proprietary biodegradable emulsified semiochemical dispenser containing Grapholita molesta (OFM) sex pheromone and small amounts of insecticide, proved to be economical, adaptable, easy to apply, and highly effective in controlling high OFM populations densities in commercial apple orchards. A single application of SPLAT-OFM A&K promoted continued trap shutdown, substantially decreased numbers of immature OFM findings, and improved the quality of fruit at harvest. Check plots under traditional management relying on insecticide applications sustained large populations of OFM, as reflected by large numbers of males captured in monitoring pheromone traps and larval damage.
