Second generation breeding starts in Sudan/Eritrea outbreak

Groups of late instar hoppers, immature and mature adults are present on the Red Sea coastal plains between Port Sudan to Massawa, Eritrea. A small mature swarm reportedly moved south along the coast towards Massawa earlier this week, reaching Foro on the 13th. A second generation of breeding is in progress with reports of new gregarious hatchlings forming small groups in Eritrea. Ground control operations are underway in both countries. As ecological conditions remain favourable, additional laying and hatching are expected during the remainder of January. Thereafter, breeding is likely to decline based on current rainfall forecasts. Elsewhere, breeding is likely to be in progress in subcoastal areas (Wadi Oko/Diib) in northeast Sudan.

In Saudi Arabia, small immature groups and swarms began arriving on 6 January near farms on the western and northern edge of the Empty Quarter south of Riyadh between Al Sulayyil and Al Aflaj, and south of Haradh. Ground control operations are in progress. These swarms probably originated from breeding in the Empty Quarter along the border of Oman/Yemen/Saudi Arabia where good rains fell from cyclones Mekunu (May) and Luban (October). There is a risk that the swarms will mature and lay eggs on the edges of cropped areas. On 15 January, a mature swarm was reported on the northern Red Sea coast near Rabigh.
