Synopsis (short abstract) Hot and dry weather accelerated Moroccan Locust (DMA) development and late-instar hoppers and adults prevailed in its populations. In the southern areas of Central Asia (CA) its life cycle came to an end while swarm flights, mating and egg-laying continued elsewhere. During the forecast period, DMA egg-laying will subside and adults will die off everywhere. Italian Locust (CIT) and Migratory Locust (LMI) hopper development was in progress in all countries except Afghanistan and fledging occurred at the end of the month. For both CIT and LMI, mating and egg-laying will take place during forecast period. In total, about one million ha were treated in CCA countries in June and about 1.6 million ha since the beginning of the 2019 campaign. This is less than a half of the area treated in the same period in 2018. The largest declines in infested and treated areas took place in Kazakhstan and Russia.

Moroccan Locust (DMA) hopper development was in progress in Kazakhstan and the Russian Federation while it was coming to an end in Azerbaijan, Georgia as well as in southern Central Asian (CA) countries where fledging, mating and egg-laying started. During the forecast period, DMA breeding will become widespread in all countries and the species will start disappearing in southern CA. Italian Locust (CIT) hatching occurred and hopper development was in progress in all countries except Afghanistan, where it was not reported as a pest. Migratory Locust (LMI) hatching started in Uzbekistan and Kazakhstan. For both CIT and LMI, fledging will start during the forecast period. In total, 524 342 ha were treated in CCA countries since the beginning of the 2019 campaign. This is only 36% of the area treated in the same period in 2018. Caucasus. DMA hopper development continued in Azerbaijan and probably in Georgia. Adults started scattered flights and mating in late May. CIT hopper development was in progress in Azerbaijan while hatching has not yet started in Armenia. A total of 32 625 ha were treated in May in Azerbaijan. Central Asia. DMA hopper development was coming to an end, fledging occurred and mating and egg-laying started in southern Central Asian countries (Afghanistan, Tajikistan, Turkmenistan and Uzbekistan). DMA hopper development was in progress in Kazakhstan and Russia. CIT hopper development was in progress in all countries, except in Afghanistan where the species was not reported. LMI hatching started in late May in Kazakhstan and Uzbekistan where young hoppers were observed. In May, almost 1 007 000 ha were treated.

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.

Moroccan Locust (DMA) lifecycle came to an end in most parts of Central Asia (CA); fledging, mating and egg-laying continued in some parts as well as in Caucasus. Due to increased number of DMA populations and large spread of adults in the south of the Russian Federation, the situation there was considered as dangerous. Italian Locust (CIT) fledging started in CA and its hopper development continued in Caucasus and the Russian Federation. Migratory Locust (LMI) hatching and hopper development continued in Kazakhstan and the Russian Federation. In the forecast period, DMA lifecycle will come to an end everywhere while CIT hopper development will continue in Caucasus, the Russian Federation and Kazakhstan. LMI hopper development will continue in northern and western regions of Kazakhstan and the Russian Federation while fledging will occur in other regions. Since the start of the campaign and till the end of the reporting period, a total of 2 077 205 hectares (ha) have been treated in all Caucasus and Central Asia (CCA), which is about 30% higher as compared to 2022 (1 478 345 ha at the same period). This is due to an increase of infestations in CA while they are decreasing in Caucasus.
