   <abstract xml:lang="ru">
    <p>Фосфин (PH₃) остается основным фумигантом для защиты зерновых запасов в России, однако его эффективность зависит от температуры, влажности воздуха, стадий развития вредителей и сорбции зерном. Показаны оптимальные условия: температура +25...+30 °C и относительная влажность 60–70 %. Температура ниже 15 °C или влажность ниже 50 % резко снижают токсичность. Автор анализирует дифференциальную чувствительность стадий: личинки наиболее восприимчивы, яйца наиболее устойчивы. Рассмотрены молекулярные механизмы резистентности (мутации rph1, rph2), сорбция фосфина зерном (20–40 %) и газопроницаемость. Предложены практические рекомендации по оптимизации фумигации и мониторингу резистентности.</p>

    <p>Phosphine (PH3) remains the primary fumigant for protecting grain reserves in Russia. However, its efficiency depends on temperature, air humidity, pest development stages, and grain sorption. Optimal conditions are temperature +25...+30 °C and relative humidity 60–70 %. Temperature below 15 °C or humidity below 50 % sharply decreases the toxicity of phosphine. The authors analyse the differential sensitivity of pest development stages: larvae are highly susceptible, eggs – highly resistant. The paper highlights the molecular mechanisms of resistance (rph1, rph2 mutations), phosphine sorption by grain (20–40 %), and gas permeability. It includes practical recommendations for fumigation optimisation and resistance monitoring.</p>
