The insecticidal properties and mechanisms of high-voltage air-based atmospheric cold plasma using a contained dielectric barrier discharge reactor were investigated against Tribolium castaneum as an important bio-contaminant in stored grains spoilage. The mortality of 95.0%–100% for preadult stages can be achieved within seconds of treatment, but longer plasma exposure (5 min) is required to kill adult insects. Cold plasma treatment reduces both the respiration rate and the weight of insects and affects the levels of oxidative stress markers in adult populations. Sufficient toxicity is achievable through plasma process control in air to address the range of insect lifecycle stages that are disease vectors and pose risks for grain stability in storage. Balancing insecticidal activity with grains' quality retention can provide a route to sustainable integrated pest management.

用于害虫控制的冷等离子体：Tribolium castaneum 死亡率和响应处理的防御机制

使用封闭式介质阻挡放电反应器研究了高压空气基大气冷等离子体对Tribolium castaneum的杀虫特性和机制作为储藏谷物腐败过程中的重要生物污染物。成虫前阶段的死亡率可以在几秒钟内达到 95.0%–100%，但需要更长的血浆暴露（5 分钟）才能杀死成虫。冷等离子体处理降低了昆虫的呼吸速率和体重，并影响了成年种群的氧化应激标志物的水平。通过空气中的等离子体过程控制可以实现足够的毒性，以解决昆虫生命周期阶段的范围，这些阶段是疾病媒介，并对储存中的谷物稳定性构成风险。平衡杀虫活性与谷物质量保持性可以为可持续的综合害虫管理提供途径。
