The present study is the first modeling effort at a global scale to predict habitat suitability of fall armyworm (FAW), Spodoptera frugiperda and its key parasitoids, namely Chelonus insularis, Cotesia marginiventris,Eiphosoma laphygmae,Telenomus remus Trichogramma pretiosum, be considered for biological control. An adjusted procedure machine-learning algorithm, maximum entropy (Maxent), was applied experiments. Model predictions showed particularly high establishment potential five...
Fall armyworm (FAW) Spodoptera frugiperda (J.E. Smith) and southern (SAW) eridania (Stoll) have become major threats to crops in Africa since 2016. African governments adopted emergency actions around chemical insecticides, with limited efforts assess the richness or roles of indigenous natural enemies. Field surveys laboratory studies were conducted identify performance parasitoids associated spodopterans Cameroon. FAW was most abundant spodopteran pest. Telenomus remus (Nixon),...
After five years of its first report on the African continent, Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) is considered a major threat to maize, sorghum, and millet production in sub-Saharan Africa. Despite rigorous work already conducted reduce FAW prevalence, dynamics invasion mechanisms Africa are still poorly understood. This study applied interdisciplinary tools, analytics, algorithms dataset with spatial lens provide insights project intensity infestation across The data...
Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) threatens maize, sorghum, and millet production in Africa. Despite rigorous work done to reduce FAW prevalence, the dynamics invasion mechanisms are still poorly understood. This study applied interdisciplinary tools, analytics, algorithms on a dataset provide insights projections intensity of infestation across The data collected between January 2018 December 2020 were matched with monthly average climatic environmental variables....
Abstract 1 Based on climate data from a network of agrometeorological stations in Norway, the effects current and future regimes spatial temporal distribution Codling moth ( Cydia pomonella ) establishment potential Colorado potato beetle Leptinotarsa decemlineata were investigated. 2 The study was accomplished using climex , dynamic matching‐ response estimation model, which predicts an organism based its known geographical distribution. 3 Validation model predictions for C. against field...
Lambda-cyhalothrin (λ-cyhalothrin) is the most commonly used pyrethroid insecticide for vegetable farming in Benin. This misused and overused by farmers, hence may pose health hazards to consumers. We monitored λ-cyhalothrin residues lettuce cabbage from farms at market gates Cotonou Parakou using high performance liquid chromatography (HPLC) analysis techniques. These were also on samples directly (on-farm sampling) 14 days post-treatment. Potential factors such as photolysis hydrolysis...
The southern armyworm (SAW) Spodoptera eridania (Stoll) (Lepidoptera: Noctuidae) is native to the tropical Americas where pest can feed on more than 100 plant species. SAW was recently detected in West and Central Africa, feeding various crops including cassava, cotton, amaranth tomato. current work carried out predict potential spatial distribution of four its co-evolved parasitoids at a global scale using maximum entropy (Maxent) algorithm.SAW may not be huge problem outside range (the...
The fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), has now become a pest of global concern. Originally known to be endemic the Western Hemisphere, its first detection in Africa was followed by spectacular outbreaks and spread almost all sub-Saharan countries. rapid incursion S. on maize (Zea mays L.; Poaceae) fields highlighted crucial need for comprehensive assessment integrated management strategies most smallholder farms. However, these cannot successfully...
Each year, Africa loses half of its harvest to pests (insects, pathogens, nematodes, weeds). To offset these losses and improve food security, pest management needs be revamped urgently. Based on a synthesis all 58 projects conducted by IITA in 55-year history, we advocate here for the implementation five following key climate-smart interventions, which have been shown increase yields decreasing CO2 outputs compared current practices that are largely based use synthetic pesticides: 1....
Fall armyworm (FAW) Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) was recorded for the first time in 2016 attacking maize fields central and west Africa. Soon after, several other regions countries have reported pest almost entire sub-Saharan In present study, we assumed that (i) a variety of alternative plant species host FAW, especially during off-season, (ii) wide range local parasitoids adapted to FAW (iii) parasitoid composition abundance vary across seasons. During...
The influence of temperature on oviposition behavior, adult longevity, and fecundity two Norwegian populations the codling moth, Cydia pomonella (L.), was investigated within range 12.3–25°C. In addition, lower threshold temperatures (T0) degree-day (DD) requirements for three egg developmental stages are given. results showed that C. lay eggs at than reported previously from other countries. Eggs were deposited in ≈40% containers an average 12.3°C. However, below 15°C, <40%...
1 The banana weevil Cosmopolites sordidus Germar (Coleoptera: Curculionidae) is a major pest in (Musa spp.) growing areas. known to be relatively sedentary and closely associated with its host plant but little about the species' ability migrate between fields nonhost habitats. 2 Mark–recapture experiments were conducted assess weevils' migration potential, possible differences sexes, relative attractiveness of pseudostem pheromone baits. 3 One thousand two hundred marked weevils released...
