Synopsis (short abstract) The locust control campaign was completed in all countries by the end of the month. The locust situation was considered as calm in August, except in some areas of the Russian Federation where it was classified as caution due to flying adults of Italian (CIT) and Asian Migratory Locusts (LMI). Last treatments of 2024 were carried out on 35 554 ha in a few Caucasus and Central Asia (CCA) countries. In total, control operations covered 4 263 652 hectares (ha) in 2024 in CCA. The overall treated area increased by about 60% compared to the previous year (4.3 million ha against 2.7 million ha), mainly due to an increase of infestations in the following three countries: Kazakhstan (93%), Kyrgyzstan (80%) and the Russian Federation (42%). Infested and treated areas generally decreased in the Caucasus region while they were close to 2023 for the other CCA countries. During the forecast period, CIT and LMI natural life cycles will come to an end and most of the countries will start or continue autumn surveys for locust egg-pods.

    Moroccan Locust (DMA) fledging and mating started in all Central Asia (CA) as well as egg-laying mainly in the southern parts. DMA hopper development continued in Azerbaijan, Georgia and the Russian Federation. The DMA situation was classified as cautious in most countries where it is present, but as dangerous in Kyrgyzstan due to outbreaks in some southern districts. Around mid-May, swarm flights, including across borders, were reported by Afghanistan and Tajikistan, where additional control operations were carried out. Italian Locust (CIT) hatching started and hopper development continued in most Caucasus and Central Asia (CCA) countries. Migratory Locust (LMI) hatching was reported in Kazakhstan and the Russian Federation. During the forecast period, the DMA lifecycle will come to an end in CA, but mating and egg-laying will happen in Caucasus and the Russian Federation. CIT hopper development will continue in Azerbaijan, Georgia, Kyrgyzstan, the Russian Federation and northern regions of Kazakhstan. CIT fledging will occur in other regions of Kazakhstan, and also in Tajikistan and Uzbekistan. LMI hopper development will continue in Kazakhstan and the Russian Federation. In total, 1 049 172 hectares (ha) have been treated in CCA from the beginning of the 2024 campaign until the end of May, which is 35 percent higher compared to the same period in 2023 (778 220 ha).

    Mass hatching of the Moroccan Locust (DMA) started in the three southern Central Asia (CA) countries in March mainly, during the second decade in Tajikistan and Uzbekistan and the third decade in Afghanistan. No hatching was reported elsewhere. During the forecast period, DMA hopper development will continue in the above mentioned countries while hatching will begin in Kazakhstan, Kyrgyzstan, Turkmenistan, the Russian Federation, as well as in Azerbaijan and Georgia. Italian Locust (CIT) hatching may start in the southern CA countries at the end of the forecast period. Asian Migratory Locust (LMI) hatching is not expected in April. In March, 8616 hectares (ha) were treated against DMA in Tajikistan and Uzbekistan, which is three times lower compared to last year (25 720 ha in 2023).

    Moroccan Locust (DMA) hatching and hopper development was in progress in all Caucasus and Central Asia (CCA) countries. Italian Locust (CIT) hatching had been recorded only in southern Kazakhstan at the end of April. Migratory Locust (LMI) hatching was recorded only in Krasnodar region of the Russian Federation. In the forecast period, DMA hopper development will continue in the Caucasus and the Russian Federation, while fledging and mating will occur in Central Asia (CA) countries. CIT hatching will start in all CCA countries. LMI hatching may start in Azerbaijan and Kazakhstan and continue in the southern Russian Federation and Uzbekistan at the end of the forecast period. In total, 335 094 hectares (ha) have been treated in CCA countries since the start of the 2024 campaign, which is 17% higher compared to the same period in 2023 (283  969 ha).
