Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

Population Ecology, EarlyView.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

Double‐Stranded DNA Reduces dsRNA Degradation in the Saliva and Significantly Enhanced RNAi‐Mediated Gene Silencing in Halyomorpha halys

Advanced Biology, EarlyView.
The invasive pest Halyomorpha halys causes significant crop losses requiring innovative pest control strategies such as RNA interference (RNAi). However, oral RNAi is largely ineffective in H. halys. This study shows that double‐stranded DNA (dsDNA) stabilizes dsRNA in saliva by inhibiting a highly expressed nuclease.

Dynamic eIF3‐S6 Phase Separation Switch Instructed by m6A Modification Drives the Molting of Locusts

Advanced Science, EarlyView.
This research reveals that reduced m6A modifications during insect molting trigger liquid–liquid phase separation (LLPS) of the m6A reader eIF3‐S6, which binds and stabilizes key molting mRNAs, including EcR and Cht10. Disrupting m6A or LLPS causes cuticle remodeling defects and molting failure, highlighting the synergistic control of gene expression ...
