Journal ArticleDOI
Forecasting the global extent of invasion of the cereal pest Spodoptera frugiperda, the fall armyworm
TL;DR: Fall armyworm, Spodoptera frugiperda, is a crop pest native to the Americas, which has invaded and spread throughout sub-Saharan Africa within two years as discussed by the authors.
Journal ArticleDOI
Insect pest problems in tropical agroforestry systems : Contributory factors and strategies for management
M. R. Rao,M. P. Singh,Roger Day +2 more
TL;DR: For exploiting biological control as a potent, low cost and environmentally safe tool for pest management in agroforestry, research should focus on understanding the influence of ecological and management factors on the dynamics of insect pest-natural enemy populations.
Journal ArticleDOI
Updated assessment of potential biopesticide options for managing fall armyworm (Spodoptera frugiperda) in Africa
M. Bateman,Roger Day,Ivan Rwomushana,Sevgan Subramanian,Kenneth Wilson,Dirk Babendreier,Belinda Luke,Steve Edgington +7 more
TL;DR: This study identifies biopesticide active ingredients (AI) which are registered for use against FAW and provides an assessment of how appropriate these will be for use by smallholder farmers in Africa.
Journal ArticleDOI
Global crop impacts, yield losses and action thresholds for fall armyworm (Spodoptera frugiperda): A review
Kathy Overton,James L. Maino,Roger Day,Paul A Umina,Bosibori Bett,Daniela Carnovale,Sunday Ekesi,Robert L. Meagher,Olivia L. Reynolds +8 more
TL;DR: The reporting of economic injury levels and action thresholds varied significantly both between and within crops, highlighting the need for a standardised approach when measuring FAW pressures or densities that elicit management responses.
