Abstract

Emergency Transboundary Outbreak Pests (ETOPs) situation for August with a forecast through mid-October 2018.

Abstract

The Desert Locust (Schistoseca gregaria-SGR1) situation remained generally calm during August and only a few isolated adults were detected in a few places in western (WOR), central (COR) and eastern (EOR) outbreak regions. Forecast: Small-scale breeding is likely in parts of the summer breeding areas in WOR, COR and EOR during the forecast period, but significant developments are not likely. Red (Nomadic) Locust (Nomadacris septemfasciata) (NSE): NSE swarms and concentrations were controlled in Malawi during August. Swarms are expected to have formed in Tanzania and Mozambique. Tree Locust, Anacridium sp. outbreaks were reported in several countries in Kenya during August and Crop Protection Services and the Desert Locust Control Organization for Eastern Africa (DLCO-EA) carried out control operations. Central American Locust, Schistocerca piceifrons piceiferons (CAL): Mixed populations of low density locusts were detected in Mexico and residual populations were observed in Nicaragua and El Salvador during August. South American Locust, Schistocerca cancellata (SCA): Isolated adult locusts were sighted in Chaco Province in Argentina during joint surveys carried in August. Italian (CIT), Moroccan (DMA), and the Asian Migratory Locusts (LMI): DMA is expected to have ended in the southern region and continued developing in Central Asia and the Caucasus and will gradually disappear while CIT and LMI will continue developing during the forecast period. Fall Armyworm (Spodoptera frugiperda) (FAW): FAW continued being a problem to maize and other crops in eastern, central and western Africa during August. It was detected in Yemen in mid-July. The pest continued spreading in southern India where it was reported causing damage to maize crops. It will likely spread to other countries in southern, southeastern and eastern Asian countries (for more info, refer to pages 10-13). African Armyworm (AAW) (Spodoptera exempta): AAW outbreak was not reported in August. Southern Armyworm (Spodoptera eridania) (SAW), native to the Americas and common from southern USA to Argentina has not yet been detected in Africa on an outbreak scale, but if and once established, this ravenous pest could become a heavy burden to small-holder farmers. Quelea birds (QQU): QQU outbreaks were reported in Kenya and in several provinces of Zimbabwe in August and control operations were launched in both countries. Active surveillance, monitoring, reporting, information sharing and timely preventive interventions remain critical at all times to abate the threats ETOPs pose to crops and pasture. USAID/OFDA/PSPM monitors ETOPs regularly in close collaboration with its network of national PPDs/DPVs, regional and international pest monitoring and/or control entities, including FAO, CLCPRO, CRC, DLCO-EA, and IRLCO-CSA, as well as Agency partners, and NGOs and provides timely analytical bulletins and reports to stakeholders across the globe.
