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.

Entomologia Experimentalis et Applicata, EarlyView.Spodoptera litura neonates showed increased movement on Bt‐expressing Bollgard 3 (BG) cotton leaf discs but did not initially avoid it. Survival was higher when larvae could move from BG3 to non‐Bt leaf discs. On whole plants, more larvae dispersed from hatching on BG3 cotton compared to non‐Bt cotton. These findings suggest the larval movement differs

Ethology, EarlyView.We raised fall field crickets in acoustic environments of silence, their own song, traffic noise, or the song of the recently introduced Japanese burrowing cricket and measured development, size, and adult survival. We found that crickets reared with burrowing cricket song developed more quickly than crickets reared in silence.
