Desert Locust – Update July 29, 2020

SOUTH-WEST ASIA. Summer breeding is in progress along both sides of the Indo-Pakistan border . In India, large groups of adults and swarms lay eggs over a large area of ​​Rajasthan between Jodhpur and Churu while hatching and banding from previous egg-laying has occurred further south of Phalodi in Gujarat . In Pakistan, hopper groups and bands are present in the Nagarparkar area, Tharparka, south-eastern Sindh. Adult groups are scattered throughout Cholistan and other parts of Tharparkar which will lay eggs shortly. In Iran, locust numbers have declined and the situation has improved. Survey and control operations are underway in all countries.

EAST AFRICA. The swarms resulting from the spring breeding move north towards the summer breeding areas. In Kenya, there has been a remarkable decline of immature swarms in the northwest due to control operations and migration to Ethiopia. However, swarms are still present in parts of Samburu and in Turkana near the border with Uganda.. In Ethiopia, immature swarms are mainly present in the Somali region and, to a lesser extent, in parts of Afar, Amhara and Tigray regions. In Somalia, immature swarms are present on the northern plateau where some of them have started to mature. Survey and control operations are underway in the three countries. In Sudan, low numbers of solitarious adults are present between Eritrea and North Kordofan, while mostly immature adults are present further north in the Nile Valley. Small-scale breeding will begin shortly in areas of recent rains. So far, there are no reports of swarms arriving from northwest Kenya. Intensive surveys are underway.

ARABIAN PENINSULA. Yemen continues to be of concern due to continued good rains and breeding in interior areas where hopper bands and swarms are forming. Survey and control operations are underway in some areas. In Oman , control operations are underway against hopper groups and bands which have formed on the south coast near Salalah while solitarious adults are present in adjacent areas of the interior. In Saudi Arabia, localized infestations of solitarious adults are present in the southwest near Najran.

WEST AFRICA. The situation remains calm. Solitarious adults are present in the summer breeding areas of southern Mauritania , central and northern Niger , and western and eastern Chad where laying will occur shortly in areas of recent rains. . As the threat of a swarm invasion continues to diminish, there is a need to maintain rigorous vigilance, preparedness and surveillance.
