LOCUST BULLETIN n. 52 - AUGUST 2017
Warm temperatures prevailed everywhere although the weather was variable and rains fell locally in Central Asia; conditions were globally suitable for locust breeding. Moroccan Locust (DMA) breeding continued in Kazakhstan and Russia while its life cycle was completed in Azerbaijan (and already last month in the other countries). Italian Locust (CIT) breeding was in progress in Kazakhstan and Russia and was coming to an end in Kyrgyzstan and Tajikistan. Migratory Locust (LMI) breeding was in progress in Kazakhstan, Russia and Uzbekistan. More than 61 000 ha were treated in August in CCA and more than 4 million ha since the start of the 2017 anti-locust campaigns. No further locust development is expected this year. Surveys will continue in most countries during the coming weeks, shifting from egg-laying to egg-beds.
