Our thresholds agree in general with research results in China and Inner Mongolia, e.g., Hao and Kang [16]. Weekly maps of predicted grasshopper hatching and development were constructed using ESRI Arc GIS Spatial Analysis (inverse distance weighting), converted from units of heat accumulation to expected insect stage in the field, and posted on the website during the growing season in 2009 and 2010. The site was publicized in grower publications. There were 1600 visits to the site during the pest management season. We are currently testing a Microsoft “Silverlight” application that will allow rapid, interactive examination of the monitoring data by participants.
