Predicting the seasonal distribution of fall armyworm in North America using species distribution models

Pest Management Science, EarlyView.
The species distribution model predicts fall armyworm habitat expands in summer, covering much of the central and eastern USA in July–August, before contracting again in September. Abstract BACKGROUND Species distribution models (SDMs) are widely used in pest management to predict outbreak areas.

Genetic characterization of fall armyworm (Spodoptera frugiperda) in Ecuador and comparisons with regional populations identify likely migratory relationships.

PLoS ONE, 2019
Fall armyworm, Spodoptera frugiperda (J. E. Smith), is an important agricultural pest native to the Americas that has recently been introduced into the Eastern Hemisphere where it has spread rapidly through most of Africa and much of Asia.

Host-plant adaptation as a driver of incipient speciation in the fall armyworm (Spodoptera frugiperda)

bioRxiv, 2022
Background Divergent selection on host-plants is one of the main evolutionary forces driving ecological speciation in phytophagous insects. The ecological speciation might be challenging in the presence of gene flow and assortative mating because the ...

Has the Striga problem been solved? A field perspective critique of recent progress

Pest Management Science, EarlyView.
The potential field efficacy of recently proposed breeding, biocontrol, suicidal germination, gene editing and transgenic solutions for Striga control is critically evaluated and mostly found wanting improvements. Abstract Three root‐parasitic witchweed (Striga) species can cause up to total loss of grain and legume crops for millions of farmers in ...

Responses of the fall armyworm (Spodoptera frugiperda) to different host plants: Implications for its management strategy.

Pest Management Science, 2022
BACKGROUND The selection of suitable host plants for oviposition is critical for herbivorous insects to maximise survival of their offspring. Olfaction plays an important role in this process.

High migratory potential of fall armyworm in West Africa despite stable temperatures and widely available year‐round habitats

Insect Science, EarlyView.
Despite the minimal annual temperature variation and the widespread distribution of potential year‐round habitats in Ghana, the migratory potential of the local fall armyworm remains strong and is indistinguishable from that of the fall armyworm in China, which undergo seasonal migration.

Efficacy of Transgenic Maize LD05 Against Fall Armyworm (Spodoptera frugiperda)

Plants
The fall armyworm (Spodoptera frugiperda (J.E. Smith)), which invaded China in 2018, has caused severe corn yield losses and increased pesticide application frequency.

Intraguild Interactions of Three Biological Control Agents of the Fall Armyworm Spodoptera frugiperda (JE Smith) in Florida

Insects, 2022
The fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a maize pest worldwide. Its host range comprises more than 350 reported plant species, and it is the primary insect pest attacking maize in Florida.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.
