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.

Pest Management Science, Volume 82, Issue 5, Page 4595-4606, May 2026.Highly pathogenic isolates of Metarhizium anisopliae attracted Drosophila suzukii. Identifying the responsible compounds for this attraction could help the development of these isolates for pest monitoring and overall pest management. Abstract BACKGROUND Drosophila suzukii, commonly known as spotted wing drosophila (SWD), is a highly invasive and ...
