An RNA interference biopesticide reduces reproduction of the honey bee parasite Varroa destructor by down‐regulating embryo development pathways

Pest Management Science, EarlyView.
Varroa destructor mites exposed to dsRNA specific in sequence to a V. destructor calmodulin gene significantly effected gene expression of adult female mites sampled 5 days after entering a honey bee brood cell to reproduce. Significantly down‐regulated genes included Calmodulin and were associated with calcium ion binding and embryo developmental ...

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.
