Campylomma Bug
Wednesday May 01, 2024
Campylomma can be a pest during the bloom period when it feeds on young developing fruit. However, it is a beneficial predaceous insect that is valuable in control of soft bodied insects (such as spider mites) throughout the rest of year. DAS predicts the phenology of Campylomma during the spring, but beating tray samples need to be taken before and during the spring bloom period to determine if Campylomma is present and whether treatment is necessary.
Leafroller and Codling Moth Movement During the Season
Monday Apr 22, 2024
Movement of codling moth and leafrollers into your orchard can be the start of serious damage. Both CM and leafrollers can easily fly 5-7 miles in a single night and their reproduction is as high as those that do not fly. Although 5-7 mile flights are common, the likelihood of the moths coming to your orchard in high numbers is directly related to wind speed, distance from the source, and the environment in between the source and your orchard.
Preserving Biocontrol Agents
Monday Apr 22, 2024
Natural enemies (NE) are crucial to the long-term stability of management programs. Pesticides need to be chosen not only on the basis of efficacy against the pests, but also by minimizing their effect on natural enemies. DAS provides both the effects on pests and on the key natural enemies.
Factors Affecting Bee Pollination of Tree Fruits
Monday Apr 15, 2024
Nearly 1,000 species of bees occur in the Pacific Northwest, but only a small number of species are useful in the pollination of orchard crops. Pesticide use and loss of appropriate nesting habitat have reduced the numbers of wild bee pollinators, leaving most of the pollination for commercial orchards dependent on honeybees. The success of honeybee pollination in tree fruits is affected by a number of factors, which in part can be manipulated by orchardists and beekeepers.
Leafroller Sampling Made Easier
Monday Apr 15, 2024
Leafrollers are nearly impossible to sample when they are in the first 2-3 instars because they are so small. DAS provides intervals during which sampling should occur well ahead of time. To sample leafrollers...
