| 中文摘要: |
| 通过在赣州开展为期2年的系统调查，明确了为害赣南脐橙的粉虱种类和发生动态。经鉴定，为害赣南脐橙的粉虱为柑橘粉虱 Dialeurodes citri Ashmead 和黑刺粉虱 Aleurocanthus spiniferus Quaintance。2013年柑橘粉虱，黑刺粉虱卵、若虫、伪蛹、成虫数量平均密度分别为（7.61，6.67，5.45，47.43）头/叶（板），（3.84，2.84，1.82，31.80）头/叶（板）；2014年柑橘粉虱，黑刺粉虱分别为（8.29，6.92，5.18，27.16）头/叶（板），（7.89，6.18，4.35，24.06）头/叶（板）。2013-2014年,两种粉虱发生数量较大，全年有多个发生高峰。柑橘粉虱和黑刺粉虱是赣南脐橙上的重要害虫，需加强防治工作，控制为害。 |
| 英文摘要: |
| Through the identification and investigation for two years of whitefly specimens collecting from the navel orange orchard in Ganzhou, we confirmed the species and population dynacmics of whiteflies that infected the Gannan navel orange. The species that infected the Gannan navel orange were citrus whitefly (CW), Dialeurodes citri Ashmead (Hemiptera: Aleyrodidae)and the orange spiny whitefly (OSW), Aleurocanthus spiniferus Quaintance (Homoptera: Aleyrodidae). In 2013, the numbers of eggs, nymphs, pseudopupae, and adults of CW and OSW were 7.61, 6.67, 5.45, 47.43; 3.84, 2.84, 1.82, 31.80 individuals/each leaf （board)respectively；In 2014, the numbers were 8.29，6.92，5.18，27.16; 7.89，6.18，4.35，24.06 individuals/each leaf （board)respectively。In 2013-2014 years, CW and OSW occured in larger quantities, with multiple peaks. D. citri and A. spiniferus are the inportant pests on Gannan navel orange orchard, which need strengthen prevention and control it's damage by these pests. |
