2004 Annual Report 4.What were the most significant accomplishments this past year? D. Progress Report: This report serves to document research conducted under a specific cooperative agreement between ARS and Shepherd College. Additional details of research can be found in the final report for the parent CRIS 1931-21220-011-00D, Integrated Orchard Management for Deciduous Tree Fruit Crops, and the report for the new CRIS, 1931-21220-015-00D of the same name. Laboratory and greenhouse rearing of oriental fruit moth and its parasitoid Macrocentris have been initiated. Extrafloral nectar collections are being made to determine the daily pattern of nectar production on peach leaves. The parent CRIS has the objective of enhancing native biological control of insect pests of apple; this project supplements this objective by providing detailed information on the interaction between nectar production and insect natural enemies, especially the parasitoid of oriental fruit moth.
