This paper describes the results of a two season pilot study assessing the utility of Landsat TM satellite data for identifying and mapping land cover in jinxed agricultural regions. In order to effectively understand, model and forecast Helicoverpa population dynamics within a mixed agricultural region it is essential to have information on the spatial and temporal distribution of the various crops and weeds on which the pests develop. Host plants are an essential resource for Helicoverpa moths and their developing eggs, larvae and pupae. The distribution, type and growth stage of cultivated and wild host plants affect the regional population dynamics of Helicoverpa in three major ways
