Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

open access: yesInsect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.

Response of Aphidius colemani to aphid sex pheromone varies depending on plant synergy and prior experience [PDF]

open access: yes, 2015
A critical stage in the success of a parasitoid is the ability to locate a host within its habitat. It is hypothesized that a series of olfactory cues may be involved in altering the parasitoid's movement patterns at this stage of foraging.

Characterization of Hymenopteran Parasitoids of Aphis fabae in An African Smallholder Bean Farming System Through Sequencing of COI ‘Mini-barcodes’

open access: yesInsects, 2019
Parasitoids are among the most frequently reported natural enemies of insect pests, particularly aphids. The efficacy of parasitoids as biocontrol agents is influenced by biotic and abiotic factors.

Plant Traits and Reproduction in a Multitrophic System: The Role of Aphids, Parasitoids and Hyperparasitoids

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 822-830, August 2026.
This field mesocosm study examined the top‐down effects of hyperparasitoids, parasitoids and aphids on plant growth and fitness. Parasitoids reduced aphid populations, but this effect was attenuated by hyperparasitoids. However, these multitrophic interactions did not affect plant traits and reproduction, likely due to the plant's fast life cycle and ...

Effect of Releasing the Parasitoid, Aphidius colemani (Hymenoptera: Braconidae) on Suppression of Myzus persicae (Hemiptera: Aphididae) Populations in Eggplants [PDF]

open access: yes, 2018
In Turkey, the polyphagous aphid, Myzus persicae Sulz. (Hemiptera: Aphididae) causes economic damages to eggplant. The solitary koinobiont parasitoid, Aphidius colemani Viereck (Hymenoptera: Braconidae) is the mainly used parasitoid and commercially ...

Instar preference and parasitization of Aphis gossypii and Myzus persicae (Hemiptera: Aphididae) by the parasitoid Aphidius colemani (Hymenoptera: Aphidiidae)

open access: yesEuropean Journal of Entomology, 2004
The instar preference and parasitization (expressed as mummification rate) of Aphis gossypii Glover and Myzus persicae (Sulzer) (Hemiptera: Aphididae) by the parasitoid Aphidius colemani Viereck (Hymenoptera: Aphidiidae) were studied at 25±0.5°C, 65±5% r.

Green Oil‐in‐Water Nanoemulsions for Delivery of Phytochemicals With Pesticidal Activity for Sustainable Food Production and Safety

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Green oil‐in‐water (O/W) nanoemulsions incorporating essential oils (EOs) and food‐derived compounds are gaining prominence as biopesticidal platforms that address the growing demand for sustainable agriculture, food safety, and reduced chemical inputs.

Occurrence and parasitism of aphids (Hemiptera: Aphididae) on cultivars of irrigated oat (Avena spp.) in São Carlos, Brazil

open access: yesBrazilian Archives of Biology and Technology, 2004
The interactions between aphids and their Hymenopteran parasitoids on irrigated oats as well as the response of different cultivars of cereals regarding the resistance to these aphids and the influence on the host/parasitoid relationships were studied ...

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
