Swarms in Yemen and Eritrea

In the past few days, there have been new reports of a few swarms appearing in the highlands of Yemen and Eritrea.

In Yemen, immature swarms and adult groups were reported in and near Sana'a as well as in nearby districts. So far it has not been possible to carry out surveys to confirm the reports. The swarms probably escaped from spring breeding areas in the central interior of Saudi Arabia where aerial and ground control operations are in progress.

There is a moderate risk that a few more small swarms will move from Saudi Arabia to the summer breeding areas in the interior of Yemen and Sudan in July. Recently, there were reports of swarms or adult groups in the Asir Mountains near Taif, Saudi Arabia.

A few small swarms from eastern Ethiopia moved into the northern region of Tigray in June. At least one swarm crossed the border into the highlands of Eritrea south of Asmara at the end of the month, and it will probably continue to summer breeding areas in the western lowlands of Eritrea and adjacent areas of eastern Sudan. There is a moderate risk that a few more small swarms may arrive from northern Ethiopia where control operations are in progress.

In northern Sudan, scattered adults and a few small groups of adults are present in cropping areas along the Nile Valley.

Elsewhere, the situation remains calm. So far, very little rain has fallen in the summer breeding areas of the northern Sahel in West Africa and Sudan, and along both sides of the Indo-Pakistan border. Nevertheless, once rains fall in these areas, small-scale breeding will cause locust numbers to increase slightly but remain below threatening levels during July.
