Fall armyworm (Spodoptera frugiperda J.E. Smith) is a noctuid moth pest endemic throughout the Western Hemisphere that has recently become widespread in sub-Saharan Africa. There strong expectation of significant damage to African maize crop yield and high likelihood further dispersal, putting rest Eastern at risk. Specimens from multiple locations six countries spanning northern portion infested region were analyzed for genetic markers. The similarity haplotypes between collections was...

The fall armyworm, Spodoptera frugiperda, a moth originating from tropical and subtropical America, has recently become serious pest of cereals in sub-Saharan Africa. Biological control offers an economically environmentally safer alternative to synthetic insecticides that are being used for the management this pest. Consequently, various biological options considered, including introduction Telenomus remus, main egg parasitoid S. frugiperda Americas, where it is already augmentative...

Cashew, Anacardium occidentale L. (Sapindales: Anacardiaceae), is an important cash crop in Benin. However, its production threatened by several biotic factors, especially insects. In Benin, very few studies have focused on insects and just listed species commonly found cashew worldwide. The present investigation fills this gap presenting exhaustive inventory of insect associated with the country. survey was carried out from September 2009 to August 2010 22 orchards (5 young 17 mature)...

The recent discovery of fall armyworm (Spodoptera frugiperda, J.E. Smith) in Africa presents a significant threat to that continent's food security. species exhibits several traits the Western Hemisphere if transferred would significantly complicate control efforts. These include broad host range, long-distance migratory behavior, and resistance multiple pesticides varies by regional population. Therefore, determining which subpopulations are present could have important implications for...

The fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is an invasive insect pest attacking maize in Ghana and sub-Saharan Africa countries. Biological control will need to be important management strategy, a first step was identify potential natural enemies. Sampling conducted different localities of the 10 regions from May Nov 2017. A total 1,062 larvae were collected 106 farms, presence enemies recorded 18 (17.0%) farms. Among recorded, 7 species parasitoids:...

Introduction. Les Tephritidae ont une importance economique majeure dans les regions tropicales. Au Benin, nous n'avions que tres peu d'informations disponibles sur especes de mouches des fruits infeodees au manguier si ce n'est la manifestation leurs degâts. Nous avons donc effectue observations preliminaires le Nord du Benin durant campagne mangues en 2005 afin d'identifier cause, suivre fluctuations populations et d'estimer pertes qui leur sont imputables.

Abstract BACKGROUND The papaya mealybug, Paracoccus marginatus , is a highly polyphagous invasive pest that affects more than 200 plants, many of which are economic importance. We modelled the potential distribution P. using CLIMEX, process‐oriented, climate‐based niche model. combined this model with spatial data on irrigation and cropping patterns to increase real‐world applicability RESULTS resulting agreed known points for broad areas where has been reported, but no GPS were available....

Abstract The pest species Spodoptera frugiperda , which is native to North and South America, has invaded Africa in 2016. consists of two strains, the corn-strain rice-strain, differ their sexual communication. When we investigated populations from Benin Nigeria, consisting rice-corn-hybrid descendants, found no strain-specific communication differences. Both genotypes exhibited same pheromone composition, around 97% (Z)-9-tetradecenyl acetate (Z9–14:Ac), 2% (Z)-7-dodecenyl (Z7–12:Ac), 1%...
