Synopsis (short abstract) Favored by hot and dry weather, Moroccan Locust (DMA) hopper development accelerated in Azerbaijan, Georgia, Russian Federation and mating and egg-laying took place in the second half of the month. DMA mating and egg-laying gradually subsided by the end of June in most Central Asia (CA) countries. In some CA countries transboundary DMA swarm flights occurred, requiring repeated chemical treatments. In general, chemical campaign against DMA was over by the end of June. Hopper development of the Italian Locust (CIT) continued, including with band formation, in Azerbaijan and Georgia where treatments were carried out while it was accomplished followed by fledging and mating in the southern CA countries. Migratory Locust (LMI) hopper development in Azerbaijan, Kazakhstan, Russian Federation and Uzbekistan was accelerated by hot weather. An area of over 900 000 ha was treated in May 2020; in total, about 1.5 million ha have been treated since the beginning of the campaign, which is close to 2019 level.

    Locusts in CCA General situation in May 2020 Forecast for June 2020 Moroccan Locust (DMA) hopper development continued in Azerbaijan and Georgia and finished in most Central Asia (CA) countries followed by fledging, mating and egg-laying. In many countries, particularly in Kyrgyzstan and Tajikistan, anti-locust campaign was seriously hampered by COVID-19, and some DMA infestations were not treated in time. As a result, swarm flights including transboundary ones took place in many areas in CA. Hopper development of the Italian Locust (CIT) started in most countries and will continue in June; in May the situation generally remained under control. In Caucasus, cool and wet weather slowed down hopper development of both CIT and DMA. Migratory Locust (LMI) hatching started in Uzbekistan, Kazakhstan and Russian Federation; hopper development will occur in June. A total of over 600 000 ha were treated in May 2020, which is 50% more than in May 2019.
