The pear odor, ester, ethyl (2E, 4Z)-2,4- decadienoate (PE) discovered by USDA ARS and co-patented and developed with Trece Incorporated has been shown to significantly influence behavior of adult male and females and larvae of codling moth(CM). Novel formulations containing PE have been tested and commercialized as monitoring systems for orchards treated conventionally and/or with mating disruptants. Other novel liquid and solid formulations containing PE have been shown to enhance pheromone and insecticide based control applications targeting adults and larvae, respectively. Large and small scale trials conducted globally suggest that novel DA based technologies will contribute widely to future CM pest management programs. A novel monitoring system was created including an original trap design and formulations containing host plant volatiles and cucurbatacin. The patented system has been extensively and successfully tested in USDA ARS sponsored area-wide programs as an indicator of treatment threshold and since commercialized. Additional novel cucurbitacin based gustatory stimulant formulations co-developed by Trece and USDA ARS have provided equal or better control at low rates of certain insecticides when compared to their full field rates. Large-scale trial results suggest that the foregoing novel technologies, used alone or as cohorts produce cost/effective pest management results.
