Litsea cubeba Essential Oil Reduces Postharvest Blueberry Rot by Inducing Cell Membrane Damage and Reactive Oxygen Species Accumulation in Alternaria alternata

open access: yesFuture Postharvest and Food, EarlyView.
Litsea cubeba essential oil (LCEO) reduces blueberry rot while maintaining quality. It disrupts the cellular structure and membranes of Alternaria alternata, causing solute leakage, while simultaneously inducing reactive oxygen species (ROS) accumulation and mitochondrial membrane potential (MMP) damage in the pathogen.

How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

open access: yesPest Management Science, EarlyView.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.

Commercial permethrin elicits chemoreceptive responses on different Anopheles gambiae sensory appendages

open access: yesPest Management Science, EarlyView.
Anopheles gambiae mosquitoes exhibit takeoff responses when presented to commercial permethrin headspace. This product elicits electrophysiological activity in the antennae and tarsi. However, only the chemical information acquired from the tarsi plays a major role in the observed behavioral response.
