Spatio-Temporal Dynamics of Viruses are Differentially Affected by Parasitoids Depending on the Mode of Transmission

open access: yesViruses, 2012
Relationships between agents in multitrophic systems are complex and very specific. Insect-transmitted plant viruses are completely dependent on the behaviour and distribution patterns of their vectors. The presence of natural enemies may directly affect

Rooted disruptions: Below‐ground herbivory drives contrasting natural enemy foraging for hosts and prey

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3704-3717, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Although research on below‐ground multitrophic interactions has increased, comparative studies examining how root herbivores influence the foraging behaviour of different natural enemies—especially generalist predators—remains limited.

ENTOMOPHAGES IN THE CUCUMBER PLANT PROTECTION SYSTEM

open access: yesSiberian Journal of Life Sciences and Agriculture
The relevance is due to the increased requirements for the quality of the products obtained, the increase in the market value of pesticides and the increasing resistance of pests to them. In the context of the rapid development of greenhouse technologies

Parasitism, Adult Emergence, Sex Ratio, and Size of Aphidius Colemani (Hymenoptera: Aphidiidae) on Several Aphid Species

open access: yesGreat Lakes Entomologist, 2017
Aphidius col€mani Viereck parasitizes several economically important aphid pests of small grain crops including the greenbug, Schizaphis graminum and the Russian wheat aphid, Diuraphis noxia. The ability of A. colemani to switch from S.

Survey of the Aphid Parasitoids (Hymenoptera: Braconidae: Aphidiinae) of Costa Rica with Information on Their Aphid (Hemiptera: Aphidoidea): Plant Associations

open access: yesPsyche: A Journal of Entomology, 2010
Species of Aphidiinae (Braconidae) have never been surveyed in Central America. Here we present the results of an initial inventory of the aphidiine species of Costa Rica and record the presence of ten species (four undetermined), in six genera.

Biotic and abiotic modulation of drought effects on aphids and plants

open access: yesAnnals of Applied Biology, Volume 187, Issue 2, Page 142-156, September 2025.
Drought affects aphids, plants and their relationships (solid arrows). This study provides a quantitative synthesis of how biotic and abiotic factors modulate the effect of drought on aphids and plants at molecular to community scales (dashed arrows). Out of 329 pair‐wise relationships (drought‐biotic and drought‐abiotic) retrieved from the literature,

An experimental investigation of patterns of parasitism at three spatial scales in an aphid-parasitoid system (Hymenoptera: Aphidiidae)

open access: yesEuropean Journal of Entomology, 2001
Density dependent host mortality in the interaction between the solitary endoparasitoid Aphidius colemani (Aphidiidae), and its host, the green peach aphid Myzus persicae, was examined on greenhouse peppers.

Bait Sprays Combined With Insecticides Targeted at Drosophila suzukii Have Negligible Impacts on Non‐Target Insects Compared to Full Foliar Spray Applications

open access: yesJournal of Applied Entomology, Volume 149, Issue 8, Page 1259-1269, September 2025.
ABSTRACT Current control of the invasive pest Drosophila suzukii relies primarily on insecticides, including the incorporation of phagostimulant baits. The impact of insecticidal bait sprays on beneficial insects in crops is largely unknown. In a laboratory and field trial, we exposed non‐target insects to insecticides with or without bait and compared

The residual effect of new insecticide (A19526X) on parasitic wasp Aphidius colemani Viereck [PDF]

open access: yes, 2019
Lisne uši iz porodice Aphididae predstavljaju veliki problem u poljoprivrednoj proizvodnji jer često razvijaju rezistentnost na insekticide. Zbog toga se preporuča uporaba bioloških mjera zaštite.

Ecological aspects of Aphidius colemani Viereck (Hymenoptera: Aphidiidae) on the Sitobion avenae (Fabricius) (Hemiptera: Aphididae) population in wheat culture in Medianeira, PR./
Aspectos ecológicos de Aphidius colemani Viereck (Hymenoptera: Aphidiidae) sobre a população de Sitobion avenae (Fabricius) (Hemiptera: Aphidiidae) na cultura de trigo em Medianeira, PR

open access: yesSemina: Ciências Agrárias, 2006
Aphids were the main winter-cereal problem in the 70’s in southern Brazil and it was necessary to use chemical control to avoid losses. Based in the weak performance of native parasites, 14 species of exotic parasites were introduced in 1978, and in 1984
