A Chinese research team found that thrips species Megalurothrips usitatus and Thrips palmi have developed significant resistance to various insecticides, complicating pest control efforts. They discovered that using ultraviolet-absorbing film (UVa-FG) in greenhouses achieved over 96% control efficiency and boosted crop yields for cowpea and Hami melon. Published in Tropical Plants, the study suggests that exploiting thrips' visual systems could offer an eco-friendly pest control alternative, reduce insecticide reliance, and enhance agricultural sustainability. The research also identified multiple mutations in thrips' sodium channels and nicotinic acetylcholine receptors, which contribute to their resistance.

A research team has found that field populations of the thrips Megalurothrips usitatus and Thrips palmi in China have developed high resistance to multiple insecticides, presenting significant control challenges. By utilizing ultraviolet-absorbing film in greenhouses (Uva-FG), they achieved over 96% control efficiency and increased crop yields for cowpea and Hami melon. This research highlights the potential of leveraging thrips' visual systems as an environmentally friendly control method, laying the foundation for future applications in sustainable agriculture.The findings are published in the journal Tropical Plants.In China, cowpea cultivation has a long history, primarily in temperate and tropical areas, but faces significant threats from thrips, which damage crops by feeding on young plant parts. Despite various management measures, chemical agents remain the most used control method, leading to high resistance levels in thrips populations. Currently, Megalurothrips usitatus ...
