Core Viewpoint - The introduction of the "Yellow Belt" as a new pest control method in urban areas utilizes the yellow color to attract pests, providing an environmentally friendly alternative to traditional chemical methods [2][3]. Group 1: "Yellow Belt" Pest Control - The "Yellow Belt" is designed to attract pests like aphids and whiteflies due to their tendency to gravitate towards yellow [2]. - The height of 1.2 meters for the "Yellow Belt" is scientifically chosen to maximize pest attraction while ensuring ease of maintenance and preserving the aesthetic of urban trees [2]. - Made from recyclable polyethylene and coated with a natural bio-gel, the "Yellow Belt" reduces air pollution and avoids issues related to chemical resistance in pests [2]. Group 2: Additional Pest Control Methods - Various physical pest control methods, such as black light traps and pheromone traps, are also being applied to urban tree pest management [3]. - Biological control methods include using parasitic wasps to manage pest populations, which is a common practice in pest management [3][4]. - The use of beneficial insects, such as birds, is encouraged by providing nesting boxes in urban areas to help control pest populations naturally [4]. Group 3: Chemical and Technological Innovations - Traditional chemical methods, like using mineral-based agents for tree trunk whitening, remain effective due to their low toxicity and long-lasting effects [5]. - The exploration of artificial intelligence for monitoring urban tree pests indicates a trend towards more sustainable and environmentally friendly pest management solutions in the future [5].
