Desert Locust Bulletin 478 (July 2018)

WESTERN REGION:

CALM SITUATION. Isolated adults were present in central and eastern Algeria. FORECAST. Small-scale breeding will occur in the northern Sahel of Mauritania, Mali, Niger, Chad and southern Algeria with very low numbers of hoppers appearing. No significant developments are likely.

CENTRAL REGION:

CALM SITUATION. No locusts were reported. FORECAST. Breeding may occur in parts of southern Yemen and Oman, and the Empty Quarter in eastern Saudi Arabia, where heavy rains fell from Cyclone Mekunu. Small-scale breeding will occur in the interior of Sudan and western Eritrea with very low numbers of hoppers appearing. No significant developments are likely.

EASTERN REGION:

CALM SITUATION. Isolated adults were present along the Indo-Pakistan border in Cholistan, Pakistan. FORECAST. Small-scale breeding will occur along both sides of the Indo-Pakistan border with low numbers of hoppers appearing. No significant developments are likely.

The Desert Locust situation continued to remain calm during July

Only isolated solitarious adults were reported during July in central and eastern Algeria, southern Mauritania, Sudan and along the Indo-Pakistan border. Good rains fell during July in the summer breeding areas of the northern Sahel from Mauritania to western Eritrea and along both sides of the Indo-Pakistan border, causing ecological conditions to become favourable for breeding. However, current locust numbers are extremely low due to very poor breeding during the past spring and winter. It will take several months of good rains and at least two generations of breeding before locust numbers are likely to increase significantly. Nevertheless, regular surveys should be undertaken in all summer breeding areas to closely monitor the evolution of the situation. In the Central Region, there remains a possibility of breeding in southern and eastern Yemen, southern Oman, and eastern Saudi Arabia where unusually heavy rains from Cyclone Mekunu fell in May. There is a slight possibility of breeding in northern Somalia and eastern Ethiopia in areas that received heavy rains from Cyclone Sagar in May. Regular monitoring should be maintained in all areas for the next few months.
