Functional Identification of Px-fringe and Px-engrailed Genes under Heat Stress in Chlorpyrifos-Resistant and -Susceptible Plutela xylostella (Lepidoptera: Plutellidae)

Insects, 2020
In our previous research, the fitness cost of resistance of the diamondback moth (DBM), Plutella xylostella found in insecticide-resistant DBM (Rc-DBM) under heat stress was based on heavier damage to wing veins when compared to insecticide-susceptible ...

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

Pest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Dose‐dependent efficacy of a novel dsRNA‐based solution containing vadescana for Varroa destructor control

Pest Management Science, EarlyView.
Vadescana is a novel dsRNA‐based product that targets Varroa fecundity. Vadescana applied at 4 g/brood box in one application was most effective at reducing Varroa populations for up to 18 weeks. Abstract BACKGROUND A novel dsRNA‐based product, containing a molecule called vadescana, interferes with Varroa destructor (Anderson and Trueman) fecundity ...

Endophytic fungi from two isolated Bethencourtia palmensis populations: metabolomic and bioactivity fingerprinting

Pest Management Science, EarlyView.
We compared two island populations of Bethencourtia palmensis and their culturable endophytic fungi, revealing distinct plant chemistries and a higher biopesticidal potential in the endophytic fungi from La Palma population along with high potential for the discovery of novel compounds.
