In June, the locust situation deteriorated further in Caucasus as well as in northern Central Asian countries. While the life cycle of Moroccan Locust (DMA) that survived previous control operations was coming to an end in most countries, successive and important waves of Italian Locust (CIT) hatching occurred. Asian Migratory Locust (LMI) hopper development was in progress and fledging started in some areas. Overall, control operations were carried out on more than 4.9 million hectares (ha) in Caucasus and Central Asia (CCA), a fourfold increase as compared to the previous month. Control operations will continue in northern Central Asian countries during the forecast period. The situation level was again qualified as caution or threat by most of the countries.
RECENT TRENDS (from 2006)
Over the past five years, an important trend in the five Central Asian countries is the increase of locust infested areas: they went up from 2,5 million ha in 2006 to 3.9 million ha in 2011, thus representing an increase of 54%, after a peak reaching 4,6 million ha in 2010. Similar trends exist in the adjacent countries, i.e. Afghanistan and the Russian Federation, as well as in Azerbaijan.
The below tables present the surveyed, infested and treated areas (in hectares) from 2005 to 2013 in Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan), Caucasus (Armenia, Azerbaijan and Georgia) and CCA adjacent areas (Afghanistan and Russian Federation).
