【背景】螺旋粉虱是新入侵中国海南的一种危险性害虫，化学防治是目前最主要的防治手段和应急措施。【方法】采用POTTER喷雾法监测了海南各地理种群螺旋粉虱对毒死蜱、丙溴磷、高效氯氰菊酯、高效氯氟氰菊酯、吡虫啉、啶虫脒和阿维菌素等7种药剂的抗性水平，并运用Tabashnik域性状分析法估算了螺旋粉虱对毒死蜱的抗性现实遗传力。【结果】螺旋粉虱对各药剂均处于抗性敏感阶段，抗性倍数为1．03～4．29倍。螺旋粉虱对毒死蜱的抗性现实遗传力 h2＝0．2405；预测结果表明，当田间使用毒死蜱对螺旋粉虱的防治效果达90％时，螺旋粉虱对毒死蜱的抗性提高10倍所需代数为7．09代。田间试验表明，螺旋粉虱对毒死蜱的抗性发展速率要比模型预测缓慢。【结论与意义】本研究可为螺旋粉虱的化学防治及抗药性治理提供参考。

Background] The spiraling whitefly Aleurodicus dispersus Russell is a destructive invasive species first found in Hainan, China, in 2006.As a new quarantine pest, chemical control was considered the most effective measure to depress and eradicate the field population.[Method] By the method of a Potter bioassay, we monitored the insecticide resistance of field strains of A.dsi persus to seven common used insecticides ( chlorpyrifos, profenofos, beta-cypermethrin, lambda-cyhalothrin, acetamiprid, imidacloprid, abamectin) .The realized heritability of resistance and resistance risk of A.dispersus to chlorpyrifos were evaluated using threshold trait analysis.[Result] The field strains tested displayed no resistance to insecticides, with a resistance ranging between 1.03 and 4.29.The realized heritability of resistance to chlorpyrifos was 0.2405.Theoretically, it requires 7.09 generations for A.dispersus to develop 10-fold resistance to chlorpyrifos under selective pressure of 90%mortality for each successive generation.Field trials re-vealed that the risk of resistance to chlorpyrifos was below that of the threshold trait analysis.[Conclusion and significance] This study indicated that chemical control may still be effective against this invasive pest.
