Entomological Society of Ghana (ESG) Symposium on Fall Armyworm June 27, 2018 Abstracts for Presentations Introduction, Spread and Current Status of Fall Armyworm (Spodoptera frugiperda) Management in Ghana. W. Hevi*, B. Oppong-Mensah, V. A. Clottey and L. K. B. A. Agboyi CABI West Africa Centre, 6 Agostino Neto Road, CSIR Campus, Accra, Ghana Corresponding author*: [email protected] ABSTRACT 1 The Fall Armyworm (Spodoptera frugiperda) outbreak became evident in Ghana and most African countries in 2016. The first report in Ghana was in the Yilo Krobo district of the Eastern region. In the 2017 cropping seasons it destroyed 14247 hectares of maize across the country. The Fall Armyworm (FAW) is very mobile, and attacks mainly maize but also a wide variety of other food crops and grasses serving as alternative host. Conditions in Ghana are favourable for FAW to thrive so medium and longer term responses are necessary while addressing the emergency farmers are experiencing. FAW can be difficult to control for several reasons: evidence of the actual economic and ecological impacts is not readily available for planning; management options across countries are not harmonised; and control methods used elsewhere may not work. To respond to the situation in Ghana, the Plant Protection and Regulatory Services Directorate (PPRSD) collaborated with CABI and other stakeholders in April 2017 to develop a short, medium and long term plan for FAW management. A ministerial taskforce was constituted in May 2017 comprising of experts from Ministry of Food and Agriculture (MoFA), other Ministries, NADMO, development partners and other stakeholders to co-ordinate awareness creation, surveillance and monitoring, implementation of prevention and control measures of FAW. The initial emergency distribution of pesticides to the Districts by the taskforce was underpinned with resistance management considerations. Due to anticipated increased insecticides use, government has approved and focused on the use of biorationale pesticides while efforts are underway to include other tested, effective and sustainable management options. CABI is supporting the prospection of indigenous natural enemies to augment their populations and minimize the use synthetic pesticides. The current cross-sectoral coordination and collaboration needs to be maintained to reduce the potential FAW impact on livelihoods and food security. Empowering farmers and FBOs through information sharing on what works and how to organise themselves for an integrated FAW management is encouraged.

Fall Armyworm Management in Ghana Felicia Ansah-Amprofi and Ebenezer Aboagye* Plant Protection and Regulatory Services Directorate of the Ministry of Food and Agriculture, Accra, Ghana Corresponding author*: [email protected]

ABSTRACT 2 The Fall Armyworm (Spodoptera frugiperda) was first reported in April 2016 in a Plant Clinic session in the Yilo Krobo Municipality in the Eastern Region of Ghana. This migratory pest has since spread throughout the country with maize as the preferred host. Due to the likely impact of the Fall Armyworm (FAW) menace on food security, the Plant Protection and Regulatory Services Directorate (PPRSD) of the Ministry of Food and Agriculture (MoFA) in collaboration with a multi-sectoral Taskforce that was constituted in April, 2017, developed short, medium and long-term action plans for sustainable management of the FAW. The interventions employed by the Ministry to manage the situation have been awareness creation, capacity building, Plant Clinic sessions, free insecticide distribution and setting up pheromone traps to monitor the population dynamics of FAW. Farmers are now able to identify different stages of FAW larvae. There is a high sense of awareness among farmers on the early detection of signs and symptoms of FAW infestations. Farmers are aware of management options and have more knowledge about the recommended insecticides. With the Food and Agriculture Organization’s Application (Fall Armyworm Monitoring and Early Warning Systems FAMEWS) Agricultural Extension Agents are able to estimate the percentage level of infestations. The strategy outlined for 2018 include increased awareness creation, capacity building, scouting, collection and identification of indigenous biocontrol agents. In collaboration with Centre for Agriculture and Biosciences International (CABI), Universities and research institutions, research into Integrated Pest Management (IPM) for sustainable management of the pest is on-going.

Evaluation of Alternatives to Synthetic Insecticides for the Control of the Fall Armyworm, Spodoptera frugiperda (J.E. Smith) in Ghana Samuel Adjei Mensah* and B. A. Mensah Department of Conservation Biology and Entomology, School of Biological Sciences, University of Cape Coast, Cape Coast Corresponding author*: [email protected]

ABSTRACT 3 Infestations by the fall armyworm, Spodoptera frugiperda were first reported in Ghana in 2016. In 2017, outbreaks were widespread in the country and posed a threat to production of crops, especially maize. Management of the pest has mainly been by application of synthetic chemical insecticides. For sustained management of this invasive species, it is important to find alternatives to chemicals to offset or at least reduce their effects on the environment and development of resistance by the target insects. S. frugiperda larvae collected from four sites in the Central and Greater Accra regions were subjected to molecular analysis to determine the occurrence of strains. Scouting was also done in these fields for natural enemies of the fall armyworm for possible deployment in biological control. The efficacy of aqueous extracts of leaves of Azadirachta indica and Calotropis procera against S. frugiperda larvae was tested in the laboratory and in the field. Molecular analysis showed that larvae from the four sites were 36 % rice strain and 64 % corn strain. The natural enemies identified comprised one parasitoid and three predator species. Application of extracts of both A. indica and C. procera significantly (p
