Iflavirus Covert Infection Increases Susceptibility to Nucleopolyhedrovirus Disease in Spodoptera exigua

Viruses, 2020
Naturally occurring covert infections in lepidopteran populations can involve multiple viruses with potentially different transmission strategies. In this study, we characterized covert infection by two RNA viruses, Spodoptera exigua iflavirus 1 (SeIV-1)

Plant–herbivore interactions depend on plant richness, plant and soil history

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Insect herbivores play a central role in grassland ecosystems. They depend on plants for their nutrition and exert feedback effects on plant communities. Although such reciprocal relationships are well recognized, how they are shaped by plant community diversity and ...

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.

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.
