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

open access: yesPest Management Science, EarlyView.
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.

New record of the genus Toxares Haliday (Hymenoptera: Braconidae: Aphidiinae) from Korea

open access: yesJournal of Asia-Pacific Biodiversity, 2017
The genus Toxares (Braconidae: Aphidiinae) is reported for the first time in Korea. Toxares deltiger (Haliday, 1833) is found as new to Korea. It has a wide host range causing it to be useful as a natural enemy for 31 aphid species within Aphididae ...

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

open access: yesPest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Selective leaf surface defenses: trichomes trap herbivorous leafminers but spare parasitoid wasps

open access: yesPest Management Science, EarlyView.
Hooked trichomes on kidney bean leaves selectively entrap leafminer flies but rarely affect parasitoid wasps. This morphological barrier enables pest suppression with minimal impact on beneficial insects, offering insights for breeding pest‐resistant cultivars compatible with biological control. Abstract BACKGROUND Leafminers [e.g., Liriomyza trifolii (
