Effect of aphid abundance and urbanization on the abundance of Harmonia axyridis (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2018
The factors that affect the local distribution of the invasive Harmonia axyridis are not yet completely resolved. Hypotheses predicting positive and independent effects of prey abundance and degree of urbanization on the adult abundance of this species ...

Chrysoperla externa (Neuroptera: Chrysopidae) as a Potential Biological Control Agent of Raoiella indica (Acari: Tenuipalpidae)

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 4, Page 335-342, April 2026.
First and third instar Chrysoperla externa showed efficient predatory capacity at low R. indica density, but second instar C. externa exhibits a density‐dependent predatory ability. The lacewing C. externa shows promise as a biocontrol agent for R. indica in coconut because it consumed 8362 R. indica females across all its larval instars.

Feeding site location in birch aphids (Sternorrhyncha: Aphididae): The simplicity and reliability of cues

open access: yesEuropean Journal of Entomology, 2000
To establish the importance of different cues for feeding site location in aphids, two birch-feeding species were given access to leaves that were either orientated normally or inverted.

Order matters: Autocorrelation of temperature dictates extinction risk in populations with nonlinear thermal performance

open access: yesEcology, Volume 107, Issue 3, March 2026.
Abstract Forecasting the risks caused by climate change often relies upon combining species' thermal performance curves with expected statistical distributions of experienced temperatures, without considering the order in which those temperatures occur.

Tri-trophic interaction involving host plants, black legume aphid, Aphis craccivora (Hemiptera: Aphididae) and the predator, Cheilomenes sexmaculata (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2016
Interactions involving host plants (cowpea, groundnut, cotton, sunflower, greengram, blackgram) an insect herbivore, black legume aphid Aphis craccivora Koch (Hemiptera: Aphididae) and a predator, the zigzag beetle Cheilomenes sexmaculata (Fabricius ...

Using citizen science as a research prioritization tool to detect co‐occurrences of the invasive species Harmonia axyridis

open access: yesInsect Conservation and Diversity, Volume 19, Issue 2, Page 452-459, March 2026.
We studied co‐occurrences and potential novel interactions between the invasive ladybird Harmonia axyridis and local biota (plants, arthropods and fungi) across Argentina using citizen science records. We detected co‐occurrences (mainly Asteracea and Aphididae) and previously unreported interactions (predation, parasitism, interspecific mating and ...

Morphological separation of host adapted taxa within the Hyalopterus pruni complex (Hemiptera: Aphididae)

open access: yesEuropean Journal of Entomology, 2007
Morphometric variation of individuals in field collected samples of the Hyalopterus pruni complex from various Prunus species and regions of Greece was examined, to determine whether this variation is correlated with the host-trees from which the aphids ...

An Apple a Day Does Not Keep the Weevils Away: Enhancing Vine Weevil Monitoring With Fruit‐Based Volatiles

open access: yesJournal of Applied Entomology, Volume 150, Issue 2, Page 168-178, March 2026.
ABSTRACT Vine weevil (Otiorhynchus sulcatus Fabricius; Coleoptera: Curculionidae) is an economically important pest of soft fruit and ornamental crops worldwide. Despite extensive research over three decades, the development of an effective semiochemical lure to improve monitoring for this pest remains a challenge.

Bedeutung und Bekämpfung von Schadinsekten an Winterweizen und Winterraps in Schleswig-Holstein, 1999-2001, und der Trend der Insektizid-Behandlungen von 1999-2004 [PDF]

open access: yes, 2008
In the average of 1999 to 2004 winter wheat covered 64 % of the agricultural land of Schleswig-Holstein (331.000 ha), winter oilseed rape 31 %. These two important crops (covering 95 % of the acreage) were attacked in 1999 to 2001 by a) wheat: cereal ...
