Genome wide gene-expression analysis of facultative reproductive diapause in the two-spotted spider mite Tetranychus urticae [PDF]

open access: yes, 2013
Background: Diapause or developmental arrest, is one of the major adaptations that allows mites and insects to survive unfavorable conditions. Diapause evokes a number of physiological, morphological and molecular modifications.

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

open access: yesPest Management Science, Volume 82, Issue 3, Page 2694-2707, March 2026.
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 ...

Insights Into Virus‐Encoded RNA Silencing Suppressors Across Viral Families: A Focus on Viruses Infecting Solanaceae Crops

open access: yesPhysiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Viral suppressors of RNA silencing (VSRs) are proteins that interfere with antiviral defense mechanisms and enhance infection. For plant viruses, VSRs can be encoded in viral genomes and satellite molecules and play an important role in the virus's life cycle and in overcoming host defenses.

A natural barrier: tick‐repellent potential of a spruce‐derived volatile blend against Hyalomma excavatum and Ixodes ricinus

open access: yesPest Management Science, Volume 82, Issue 2, Page 1481-1491, February 2026.
Both active and passive questing ticks, Hyalomma excavatum and Ixodes ricinus, were assessed for behavioural responses to two novel plant‐derived repellent volatile organic compound blends. Both tick species were repelled by the products, and both novo blends were significantly more repellent than currently available commercial products.
