Synopsis (short abstract) Moroccan Locust (DMA) fledging, mating and egg-laying continued in Caucasus and Central Asia (CCA) except for the southern regions of Central Asia (CA) where its lifecycle came to an end. Italian Locust (CIT) fledging started in Georgia and in CA countries. Migratory Locust (LMI) hopper development continued in Azerbaijan, Kazakhstan, Russian Federation and Uzbekistan. A dangerous situation was reported for CIT in Georgia while in other countries, the situation was classified as caution. During the forecast period, DMA breeding will continue in Kazakhstan and Russian Federation while CIT development will continue in Caucasus, Russian Federation and Kazakhstan. LMI hopper development will continue in northern oblasts of Kazakhstan and Russian Federation and fledging will occur in other regions. In total, more than 1 600 000 hectares (ha) have been treated in CCA since the beginning of the 2021 campaign till the end of June, which is 50 percent higher than in the same period in 2020.

    Natural cycles of the three locust species – Italian Locust (CIT), Migratory Locust (LMI) and Moroccan Locust (DMA) ended in late summer/early autumn in all countries with eggs laid in the soil, where they overwinter (embryonic diapause). During the forecast period, DMA hatching may occur in northern Afghanistan and southern regions of Tajikistan and Uzbekistan; no development is expected concerning CIT and LMI.

    Moroccan Locust (DMA) fledging, mating and egg-laying started in southern parts of Central Asia. DMA hopper development continued in Azerbaijan, Georgia, Kazakhstan, Kyrgyzstan and Russian Federation. Italian Locust (CIT) hatching and hopper development continued in Georgia and in Central Asian (CA) countries. Migratory Locust (LMI) hatching started in Kazakhstan, Russian Federation and Uzbekistan. DMA swarm flights including across borders were reported in the southern part of CA. The situation with DMA was critical in Tajikistan, while it was classified as caution for both DMA and CIT in most other countries. During the forecast period, DMA breeding will continue and its lifecycle will come to the end while CIT hopper development will continue in Azerbaijan, Georgia, Kyrgyzstan, Russian Federation and northern regions of Kazakhstan. LMI hopper development will continue in Azerbaijan, Kazakhstan, Russian Federation and Uzbekistan. CIT fledging will occur in other regions of Kazakhstan, Tajikistan and Uzbekistan. In total, 427 379 hectares (ha) have been treated in CCA from the beginning of the 2022 campaign to the end of May, which is 35 percent lower compared to the same period in 2021 (665 000 ha).

Italian Locust (CIT) hatching started in Turkmenistan and Uzbekistan. During the forecast period, DMA hatching will start in Georgia, Armenia and the Russian Federation and fledging and mating will occur in the southern CA countries. CIT hatching will start in Georgia, Kazakhstan, Russian Federation and probably in Armenia. Migratory Locust (LMI) hatching may start in Kazakhstan, Russia, Turkmenistan and Uzbekistan at the end of the forecast period. In total, almost 185 000 ha were treated in CCA countries since the beginning of the campaign.
