Utilizing US MODIS satellite data integrated with meteorological and field survey data, as well as pest multimodal large models, has continued to conduct remote sensing monitoring and assessment research on desert locust disasters in Asia and Africa through intelligent big data analysis and processing. This report provides a dynamic update on desert locust conditions in Morocco, Algeria, and Mauritania. Remote sensing monitoring showed that, in July 2026, desert locusts mainly affected localized areas in central-southern and southwestern Morocco, northwestern and central Algeria, and southern Mauritania, affecting 85.6, 27.0, and 15.6 thousand hectares of vegetation, respectively. This month, the affected vegetation areas in Morocco and Algeria both declined from June, while the center of locust activity showed a transition from the spring breeding areas of Northwest Africa toward the summer breeding areas of the Sahel. Spring breeding in Morocco had entered its final stage; earlier hopper groups had largely fledged, and gregarious, transiens, and solitarious populations all decreased markedly.
