A survey was conducted in September 2014 to determine the status of citrus pests in Northern Uganda. Eighty farmer fields were sampled in districts of Nwoya, Gulu, Amuru, Agago, Kitgum, Lira, Dokolo, Oyam, and Apac. The results showed leaf miner as the most prevalent pest (97.3%) and scales (38.73%) as the least among citrus orchards in the region. Agago and Dokolo had the highest orange dog (100%) and leaf miner (100%) incidences where as Oyam (87%) and Kitgum (93%) districts registered the least incidences of the similar pests. The highest (63.2%) and lowest (12%) scales incidences were recorded in Agago and Nwoya districts respectively. There was a significant relationship observed between the districts and scales incidence (p= 0.000175). Age had no significant relationship with the scales, leaf miner and orange dog pest incidences. The fact that leaf miner had the highest incidence necessitates the need for its control since it bears a strong relationship with the devastating citrus canker and alternaria brown spot disease. The study also points out to the need for control of the leaf miner for a sustainable citrus pest management plan in northern Uganda.
