DMA hopper development continued in Azerbaijan, Georgia, Kazakhstan, Kyrgyzstan and Russian Federation. Italian Locust (CIT) hatching started followed by hopper development in most Caucasus and Central Asia (CCA) countries. Migratory Locust (LMI) hatching was reported in Kazakhstan, Russian Federation and Uzbekistan. During the forecast period, DMA breeding will continue, and its lifecycle will come to an end while CIT hopper development will continue in Azerbaijan, Georgia, Kyrgyzstan, Russian Federation and northern regions of Kazakhstan.
