2016-insect pest monitoring information-updated 8/18 (download pdf)
Insects that are included for this monitoring are codling moth, navel orangeworm, oriental fruit moth, peach twig borer, obliquebanded leafroller, walnut husk fly. At least three traps for one insect species were deployed in each of 3-5 orchards. The usefulness of this information in pest management decision making may be limited. Out traps are within 5-7 miles radius from our office (UC Cooperative Extension-Stanislaus, Modesto), and insect activities can vary from orchard to orchard depending on the location, orchard history, situation of the orchard regarding the presence of alternate hosts nearby, etc. So, we encourage to use your trap counts/DD as the primary source of information and the information from our trap counts as a reference. CIMIS # 206 (Denair II) is the source of weather data for degree-days calculation.
