A nonlinear model for stage-structured population dynamics with nonlocal density-dependent regulation: An application to the fall armyworm moth
The assessment and the management of the risks linked to insect pests can be supported by the use of physiologically-based demographic models. These models are useful in population ecology to simulate the dynamics of stage-structured populations, by means of functions (e.g., development, mortality and fecundity rate functions) realistically representing the nonlinear individuals physiological responses to environmental forcing variables. Since density-dependent responses …

Assessing the risk of establishment and transient populations of Spodoptera frugiperda in Europe
The fall armyworm, Spodoptera frugiperda (J.E. Smith), is an invasive pest threatening crop production and food security worldwide. High concerns are linked to the potential establishment of the species in Europe. The high migratory capacity of S. frugiperda causes concerns about the potential impacts of transient populations invading new areas from suitable hotspots. In the present work, we developed …

Your thoughts? Some reasons given against #GM crops to control #fallarmyworm: 1). Dominance by a few agricultural companies hence creating seed dependence as farmers have to buy from them. 2) Conserve genetic resources of the country and local seed varieties.
What will it take to change the mindset of regulators / policy makers in African countries to adopt GE technology to manage pests like the #fallarmyworm?

Spraying sugar solution in maize field attract natural enemies and increase parasitism on fall armyworm.
Cultural method of pest control make a less favourable environment to the pest and make a more favourable for their natural enemies. This method is the most widely adopted approaches in integrated pest management. As a part of cultural control, spraying sugar solution (10-20%) increases the population of certain parasitoids such as Campoletis flavicincta (Hymenoptera:Ichneumonidae), …

Parasitism behavior of the braconid wasps, Coccygidium luteum and Cotesia icipe and the interaction between the two parasitoids species and their host, Spodoptera frugiperda
The research focuses on studying the interaction (Synergy/competition) and reproductive capacities of two Spodoptera frugiperda larval parasitoids (Coccygidium luteum and Cotesia icipe) in Ghana. The research also studies the life span and larval instar preference of the parasitoids. Findings from the study will enhance knowledge on the tri-trophic interactions in the ecosystems of parasitoids and …

Evaluation of Alternatives to Synthetic Insecticides for the control of the Fall Armyworm, Spodoptera fruigiperda (J.E. Smith) in Ghana

Since its invasion into Ghana in 2016, FAW has caused a lot of damage to maize and cereal crops in Ghana. As at 2016, most FAW control measures were based to a large extent on traditional knowledge and …
