End Date: Apr 30, 2014
Bioassays will be conducted with the sugar-yeast adjuvant to characterize its efficacy when combined with codling moth granulosis virus. An optimized adjuvant formulation (ratio of the two components and final concentration) will be evaluated in replicated research plots in apple and pear in year 1. Studies will be expanded to growers’ orchards in year 2. The combined use of several synthetic insecticides that exhibit ovicidal activity and sublethal effects on one or more life stages will be assessed in rotation with the virus in replicated research plots in year 1. Studies will be expanded to growers’ orchards in year 2. These studies will focus on the integrated programs’ direct efficacy for codling moth and on the resulting population densities of aphids, scale, and mites and their primary natural enemies.
