Abstract

The Desert Locust (Schistoseca gregaria - SGR1): In the central outbreak region (COR), SGR situation remained extremely serious in East Africa where significant populations are present and continue developing during May. Control operations treated more than 101,00 ha largely in Ethiopia, Kenya, Somalia, Saudi Arabia and UAR. Breeding continues in the southern and eastern coastal plains and the interior of Yemen where heavy rains and floods from the previous month created favorable conditions. In the eastern outbreak region (EOR) hoppers, adult groups and swarms from spring breeding areas in southern Iran and Baluchistan, Indus Valley, and Punjab of Pakistan persisted during this month. Immature swarms from these areas that arrived in Rajasthan, India earlier than usual, ahead of the monsoon rains, spread further, some reaching the central and northern states and triggering an alarm in the country. Control operations treated more than 231,200 ha in EOR during this month. The western outbreak region (WOR) remained calm and only local breeding occurred in Algeria while mature adults may be present in northern Mali but could not be confirmed due limited access.
