Iflaviruses in arthropods: when small is mighty

open access: yesInsect 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.

Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

open access: yesInsect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females

open access: yesIntegrative Zoology, EarlyView.
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...
