Arthropod niche differentiation linked to grazing‐induced sward islets in intensively managed agricultural pasture

open access: yesInsect Conservation and Diversity, EarlyView.
In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling

NATURAL ENEMIES OF DIURAPHIS NOXIA (STERNORRHYNCHA: APHIDIDAE) IN SLOVAKIA [PDF]

open access: yesJournal of Central European Agriculture, 2009
A study from 2002 documented the occurrence of natural enemies (parasitoid wasps, predatory fl ies, entomopathogenic fungi) associated with colonies of the Russian wheat aphid, Diuraphis noxia (Kurdjumov, 1913) (Sternorrhyncha: Aphididae), in the spring ...

Insectary Plant Species Preferences of Predators and Parasitoid Families in a Mediterranean Horticultural Agroecosystem

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The use of insectary plants to provide alternative food and shelter resources for enhancing natural enemy activity has been established as a common practice in IPM. Candidate flowering plant species have been screened and evaluated for their contribution to enhance life parameters of beneficial insects.

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, 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.

Potential Drivers of Successful Biocontrol: A Perspective on Parasitoids

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.
Parasitoids are central to classical biological control, yet predicting their long‐term effectiveness post release remains challenging. In Aotearoa New Zealand, three Microctonus (Hymenoptera: Braconidae) species have been used against pest weevils, but key aspects of their biology remain poorly understood.

Asociaciones áfido-parasitoide (Hemiptera: Aphididae; Hymenoptera: Braconidae, Aphidiinae) en cultivos hortícolas orgánicos en Los Cardales, Buenos Aires, Argentina Aphid-parasitoid associations (Hemiptera: Aphididae; Hymenoptera: Braconidae, Aphidiinae) on organic vegetable crops in Los Cardales, Buenos Aires, Argentina

open access: yesRevista de la Sociedad Entomológica Argentina, 2007
Diez especies de áfidos (Hemiptera: Aphididae) se hallaron parasitados por siete especies de parasitoides (Hymenoptera: Braconidae, Aphidiinae) en cultivos hortícolas orgánicos. Myzus persicae (Sulzer) fue el áfido más frecuentemente encontrado sobre una

A Parasitoid of Aphids Manipulates Host Mummification Site, With Effects on Survival but Not Hyperparasitism

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Parasitoid wasps can manipulate host behavior to enhance their own survival. Here we find that a parasitoid of aphids, Aphelinus chaonia, induces aphids to move to the leaf axil or leave the plant prior to pupation. This seems to have no effect on hyperparasitism, but mummy location may nevertheless impact parasitoid survival.

Temperature variability homogenized thermal responses in an ectotherm community along a European longitudinal gradient

open access: yesEcography, Volume 2026, Issue 2, February 2026.
Climate change, through rising temperatures, greater variability, and more frequent extremes, is reshaping insect phenology and thermal niches, with profound effects for pest outbreaks. Predicting these impacts requires a clear understanding of species and communities' responses across geographic gradients.

Aphid parasitism alters induced plant responses allowing a hyperparasitoid to locate its hidden parasitoid host

open access: yesNew Phytologist, Volume 249, Issue 4, Page 2055-2070, February 2026.
Summary Plants typically host insect communities composed of multiple trophic levels that are intricately linked through interactions mediated by the shared food plant. Hyperparasitoids are top‐level carnivores in such systems, preying on parasitoid larvae developing inside herbivores. These hyperparasitoids can dramatically reduce the effectiveness of

Studies on the identity of the parasitoids Aphidius colemani and Aphidius transcaspicus (Hymenoptera: Braconidae)

open access: yesEuropean Journal of Entomology, 2009
The taxonomic status of the aphid parasitoid Aphidius colemani Viereck has been questioned, especially in regard to Aphidius transcaspicus Telenga (Hymenoptera: Braconidae). The genetic association between A. colemani and A.
