文摘

Geographical Information System (GIS) is used to study Dubas bug infestation in northern Oman during 2006–2015. Spatiotemporal risk of Dubas bug infestation is modelled by hotspot analysis using the Getis-Ord statistic, Gi*. Annual hotspots over study period are concentrated in mountain plains where farms are located between gradient elevations. Average seasonal infestation levels and distribution of hotspots help monitor Dubas bug and plan resources for its treatment.
