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...
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...
Abstract Despite substantial efforts to control locusts they remain periodically a major burden in Africa, causing severe yield loss and hence of food income. Distribution maps indicating the value basic reproduction number R 0 was used identify areas where an insect pest can be controlled by natural enemy. A dynamic process-based mathematical model integrating essential features enemy its interaction with is generate risk for outbreaks, using desert locust entomopathogenic fungus...
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....
The pinewood nematode (PWN) is one of the worst tree-killing exotic pests in East-Asian countries. first European record establishment Portugal 1999 triggered extensive surveys and contingency plans for eradication countries, including immediate removal large areas conifer host trees. Using Norway as an example, we applied a simulation model to evaluate chance successful hypothetical introduction by current plan northern area where wilting symptoms are not expected occur. Despite highly...
The COVID-19 pandemic, surprised many through its impact on the food systems, resulting in collapses production value chains and integrated pest disease management sector with fatal outcomes places. However, of digital experience perspective Integrating Pest Management (IPM) is still yet to be understood. In Africa, was devastating, mostly for vulnerable smallholder farm households, who were rendered unable access markets purchase inputs sell their produce during lockdown period. By using a...
(1) We document the invertebrate fauna collected from 24 oak canopies in east and west Norway as a contribution to Norwegian Biodiversity Information Centre’s ‘The Taxonomy Initiative’. (2) A snap-shot inventory of was recorded by means emitting mist natural pyrethrum into at night using petrol-driven fogger collecting specimens butterfly nets spread on ground under canopy. (3) Almost entire catch more than 6800 identified 722 species. Out 92 species new fauna, 21 were science and,...
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...
We fogged 24 trees in two pine dominated forests Norway with a synthetic pyrethroid order to compare the canopy‐dwelling fauna of arthropods between costal (Kvam) and boreal (Sigdal) sites old (250–330 yr) mature (60–120 at Sigdal. Almost 30 000 specimens were assigned 510 species; only 93 species present both sites. Species diversity, as established by rarefaction, was similar trees. However, number new (including nine science) significantly higher suggest that scarcity trees, habitat...
Sporophores of Piptoporus betulinus (Bull. ex Fr.) Karst. and Fomes fomentarius (L. Kickx were collected during March to December 1991 from five different West Norwegian forests. Their beetle faunas are described in detail. Various factors contribute the decomposing process sporophore, change considerably this process. The host specificity obligatory polypore inhabitants is probably determined by other besides itself, because between forests productivity classes with tree compositions....
Abstract Canonical correspondence analyses (CCA) of the beetle communities found in polypore fungi Fomes fomentarius (L. ex Fr.) Kickx and Piptoporus betulinus (Bull. Karst. from five localities western Norway was applied to quantify relative importance various environmental variables. A total 2266 adult specimens were identified 57 species. Ecological qualities different forest types more important than sporophores per se. The two species have beetles, which can be explained by habitat...
We compiled the data on insect assemblage occurring within polypore Fomitopsis pinicola from six regions in Finland, Sweden and Norway. The species composition diversity of primary fungivorous beetles (Cisidae Anobidae) were similar across Fennoscandia. Cis glabratus Mellié (Cisidae) C. quadridens most frequent 70% 23% fruiting bodies average. Sulcacis fronticornis (Panzer) Ennearthron cornutum (Gyllenhal) relatively common southern Sweden, while absent study Norway Finland. Similarly,...

The fall armyworm, Spodoptera frugiperda, situation in Africa remains a priority threat despite significant efforts made since the first outbreaks 2016 to control pest and thereby reduce yield losses. Field surveys Benin Mali reported that approximately one-week post-emergence of maize plants, presence armyworm (egg/neonates) could be observed field. Scouting for eggs neonates is, however, difficult time consuming. In this study, we therefore hypothesized optimum timeframe female arriving...
In temperate forests, red wood ants (Formica aquilonia) are considered ecosystem engineers affecting properties and functions. Possible effects of F. aquilonia on species communities invertebrates plants were studied in the pine-dominated Geitaknottane forest reserve, Norway. Species richness carabids, lichens epiphytes (tree-living bryophytes) was negatively affected by ant mound density. all groups, except for snails, either positively or presence. Food availability interference...
