The egg hatch graphs depict percent egg hatch at critical stages of six apple insect pests for Biglerville, PA, and are based on temperature-driven models of hatch or emergence derived from observations at Biglerville or literature references. The graphs can be used to determine the optimum times for scouting and application of control measures. For example, insects are often most susceptible to insecticides when they are newly hatched and before they begin to damage fruit.
The updates provide seven days of forecast output provided by SkyBit Inc. (Boalsburg, PA). For more information about these pests and their management, see the 2010-2011 Pennsylvania Tree Fruit Production Guide (TFPG).
