Using Pheromone Lures, Insecticide Netting, and a Novel Food-Grade Repellent to Develop BMSB IPM Strategies
… which has diminished integrated pest management (IPM) programs that worked well otherwise. The research herein explored the use of three new tools in the development of BMSB management strategies. In one study, a BMSB pheromone lure was placed on insecticide-incorporated mesh netting to be used in …

Compatible components of the integrated pest management of Bathycoelia distincta (Hemiptera: Pentatomidae
… is a need to develop Integrated Pest Management (IPM) strategies to effectively minimize the damage caused by B. distincta and the loss of biodiversity due to agricultural intensification. The goal of this study was to investigate the role of landscape context, elevation, flying vertebrates, and …

Bio-ecological studies of Tuta absoluta in Sudan
… can be used to develop sustainable and effective IPM strategies. Results of field surveys conducted in the major tomato producing States of Sudan showed that the highest abundance of T. absoluta occurs in winter and early summer seasons (December-April). However, its population densities declined …
