The Potential for Pest Management Using Plant‐Derived Signaling Compounds

Ecological Research, Volume 41, Issue 5, September 2026.
Plant‐derived signaling compounds mediate ecological interactions among plants, herbivores, their natural enemies, and neighboring plants. This graphical summary highlights three approaches to leveraging such ecological interactions for environmentally benign pest management: (1) Recruitment of natural enemies: Using herbivory‐induced plant volatiles ...

Prey Range and Voracity of Main Insect Natural Enemies of Pests in Corsican Clementine Orchards

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 851-862, August 2026.
To assess the biocontrol potential on the main arthropod pests of clementine orchards in Corsica, laboratory experiments were carried out using five potential predators. Their prey range and voracity were tested on three pest species. Then, a global predation rate index was calculated at the scale of the entire community of insect predators.

Towards an attract‐and‐reward strategy: evaluating nectar resources and HIPVs under laboratory conditions to enhance Aphelinus mali parasitism activity, a key parasitoid of Eriosoma lanigerum

Pest Management Science, Volume 82, Issue 4, Page 3955-3963, April 2026.
Euphorbia segetalis is a promising attractant insectary plant for Aphelinus mali. Meanwhile, Vicia faba and Vicia sativa are a promising nectar resource to sustain the parasitoid in early spring when the population of Eriosoma lanigerum is low, and honeydew is scarce.
