Aphids (Homoptera: Aphididae) on Winter Wheat: Predicting Maximum Abundance of Metopolophium dirhodum

open access: yesJournal of Economic Entomology, 2018
In Central Europe, the most abundant aphid infesting the leaves of small grain cereals is Metopolophium dirhodum (Walker) (Homoptera: Aphididae). Annual variation in its seasonal dynamics was evaluated using a 25-yr series of standardized weekly censuses

Meta‐analysis on effects of Bt‐maize on nontarget invertebrates – Data transportability across continents

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Maize varieties producing insecticidal proteins from Bacillus thuringiensis (Bt) have become an important component of integrated pest management worldwide. For regulatory approval of such plants, risks to the environment need to be assessed. To make such assessments less expensive and time‐consuming, conclusions drawn from data collected in one region

The complete mitochondrial genome of Aphis gossypii Glover, 1877 (Hemiptera: Aphididae) collected in Korean peninsula

open access: yesMitochondrial DNA. Part B. Resources, 2019
Aphid gosypii Glover, 1877 is a widely recognized economically important aphid species in the world. We have determined mitochondrial genome of A. gossypii collected in Korean peninsula. The circular mitogenome of A.

Praon volucre (Hymenoptera: Braconidae: Aphidiinae), a natural enemy of Macrosiphum euphorbiae (Hemiptera: Aphididae): Life table and intrinsic rate of population increase

open access: yesEuropean Journal of Entomology, 2011
Life table data of natural enemies are often used to understand their population dynamics and estimate their potential role in the biological control of pests.

The Bacterial Flora Associated with the Polyphagous Aphid Aphis gossypii Glover (Hemiptera: Aphididae) Is Strongly Affected by Host Plants

open access: yesMicrobial Ecology, 2019
Aphids live in symbiosis with a variety of bacteria, including the obligate symbiont Buchnera aphidicola and diverse facultative symbionts. The symbiotic associations for one aphid species, especially for polyphagous species, often differ across ...

Evaluating antibiosis resistance to cabbage aphid (Brevicoryne brassicae L., 1758) in vegetable brassicas (Brassica oleracea L.) and related C‐genome brassica species

open access: yesPest Management Science, EarlyView.
Nineteen Brassica accessions were screened for antibiosis resistance to Brevicoryne brassicae. Significant variation in resistance was identified. Detailed bioassays suggest that varietal effects upon aphid pre‐reproductive period conferred observed resistance.

Relation between plant water status and Macrosiphum euphorbiae (Hemiptera: Aphididae) population dynamics on three cultivars of tomato

open access: yesEuropean Journal of Entomology, 2013
Deficit irrigation scheduling is used to increase the efficiency with which water is used in many crops including tomato, however a water deficit is predicted to favour phloem feeding insects.

Effects of timed LED regimes on tomato plant traits, performance of two‐spotted spider mites, and predatory mites (Phytoseiulus persimilis)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2300-2311, April 2025.
Light‐emitting diode (LED)‐based treatments for enhancing crop production and pest management have primarily focused on continuous treatments. This study, using Tetranychus urticae and Phytoseiulus persimilis, demonstrates that the timing of LED supplementation is crucial for designing integrated pest management strategies that improve both plant ...

The degree of protection different ants (Hymenoptera: Formicidae) provide aphids (Hemiptera: Aphididae) against aphidophages

open access: yesEuropean Journal of Entomology, 2012
Aphids play an important role in the life of many ant species supplying them with energy-rich carbohydrate food and in exchange receiving some degree of protection from natural enemies.

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

open access: yesInsect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...
