Insect pest management strategies for field crops of South Texas, emphasizing decision support and area-wide strategies built from understandings of plant-insect interactions Grant uri icon

abstract

  • For cotton, we propose to Characterize pest risk for the plant and stink bug complex, Refine decision-making tools, and Assess the association of farm and regional crop composition and structure and other landscape attributes with cotton insect pest risk. For sorghum, work will focus on the development of a management system for sugarcane aphid on grain sorghum. An interdisciplinary IPM approach will be taken (e.g., economic threshold studies integrated with natural enemy and resistant sorghum assessment) with additional ties to allied research in remote sensing strategies to increase the efficiency and effectiveness in detecting this invasive aphid pest of sorghum. Characterization of pest damage will allow establishment of IPM decision-making aids such as field monitoring methods and economic thresholds. Incorporated into a decision-support crop management system, pest risk assessment sensitive to environmental stressors and landscape attributes will allow more selective insecticide application, thus reducing production costs, preserving natural enemies, and reducing environmental risk. The specific activities target locally relevant pest complexes affecting the major field crops of South Texas. They are also well within the scope of the National IPM Roadmap and Southern Region IPM priorities such as managing sucking bugs using ecological approaches, and development of decision aids for management of pests, and USDA National Institute of Food and Agriculture program priorities such as landscape perspective in IPM, and integration of research and extension activities.
