Spatial Distribution and Abundance of Chrysomya bezziana in Jazan Province, Saudi Arabia Using GIS

Myiasis caused by Calliphorid and Oestrid flies constitute a major threat to the development of livestock industry in Kingdom Saudi Arabia. Increased veterinary concerns recently paid frequent reports on enteric pathogens larvae these flies. Although importance sheep goats Arabia, geographic distribution limits infestation caprine has never been highlighted. ArcGIS software was used assess spatial myiasis causing Jazan Province, Implemented Evolutionary algorithms maximum entropy (MaxEnt) predict map for Bioclimatic topographic data layers from Worldclim analyzed estimate percent contribution variables predicting suitable habitats myiasis. Field validation occurred evaluate habitat suitability produced model. The predictive ecological niche model found high with an AUC value 0.95 0.93 train test occurrence records, respectively, standard deviation equal 0.032. About eighteen were contribute Precipitation enhanced power (57.7%) Jackknife test. Besides, elevation, NDVI tree cover shared reduced effect distribution.
