The development and commercialization of new chemical classes of insecticides are important for efficient crop protection, particularly for combatting insecticide resistance and providing sustainable agricultural production. This study reports on oxazosulfyl, a novel "sulfyl" class of insecticide, against a wide range of insect pests of rice. In the laboratory assay, oxazosulfyl showed insecticidal activity against all developmental stages of the brown planthopper (Stål). Phosphor imaging assays and soil drench bioassays demonstrated good systemic distribution in rice plants. Oxazosulfyl showed insecticidal activity against imidacloprid- and fipronil-resistant field populations of , the white-backed planthopper (Horváth), and the small brown planthopper (Fallén), as well as the respective susceptible strains. No cross-resistance was observed among oxazosulfyl, imidacloprid, and fipronil. Oxazosulfyl with a wide insecticidal spectrum is a potentially useful pest management tool for sustainable rice production.
新型杀虫剂化学类别的开发与商业化对于高效作物保护至关重要，特别是在应对杀虫剂抗性和实现可持续农业生产方面。本研究报告了一种新型“磺酰基”类杀虫剂恶唑磺酰对多种水稻害虫的防治效果。在实验室测定中，恶唑磺酰对褐飞虱（Stål）的所有发育阶段均表现出杀虫活性。磷成像测定和土壤浇灌生物测定表明其在水稻植株中具有良好的系统分布。恶唑磺酰对吡虫啉和氟虫腈抗性田间种群、白背飞虱（Horváth）、灰飞虱（Fallén）以及各自的敏感品系均表现出杀虫活性。在恶唑磺酰、吡虫啉和氟虫腈之间未观察到交叉抗性。具有广泛杀虫谱的恶唑磺酰是可持续水稻生产中一种潜在有用的害虫管理工具。
