Desert Locust Bulletin 441 (June 2015) [EN/AR]
General Situation during June 2015
Forecast until mid-August 2015
The Desert Locust situation remained calm during June. Good rains and at least two generations of breeding will be required this summer before populations increase in the traditional summer breeding areas in the northern Sahel of West Africa and Sudan, and along both sides of the Indo-Pakistan border. So far, rains are late to arrive in the Sahel, except in central Niger and eastern Mali, while monsoon rains commenced some one to three weeks earlier than normal in India and Pakistan. Once the summer rains start, small-scale breeding will occur in the northern Sahel between Mauritania and western Eritrea. Therefore, regular surveys should commence shortly in all summer breeding areas but some places such as northern Mali, Darfur and the interior of Yemen will remain inaccessible due to insecurity.
Western Region. The situation remained calm in June. No locusts were reported in the region except for an immature adult in eastern Mali but this could not be conﬁ rmed by surveys due to prevailing insecurity. Seasonal rains started in central Niger and Tamesna, extending to eastern Mali, but were late to commence and had not began in other summer breeding areas. During the forecast period, small-scale breeding will occur in Mali and Niger, and in Mauritania and Chad once seasonal rains commence, causing locusts numbers to increase slightly. Dry conditions prevailed in Northwest Africa.
Central Region. The situation remained calm during June. No locusts were reported in the region and dry conditions prevailed. Although good rains associated with a tropical cyclone fell in northeast Oman, this is not likely to have a signiﬁ cant impact on the locust situation. So far, seasonal rains have not yet commenced in the summer breeding areas in the interior of Sudan and western Eritrea. However, they are expected to start very shortly and small-scale breeding will occur during the forecast period, causing locust numbers to increase slightly in both countries.
Eastern Region. No locusts were reported and the situation remained calm during June. The southwest monsoon arrived in the summer breeding areas along both sides of the Indo-Pakistan border during the last week of June, which was some one to three weeks earlier than usual. During the forecast period, small-scale breeding will cause locust numbers to increase slightly in both countries as a result of good rains so far.
