Targeted re-sequencing confirms the importance of chemosensory genes in aphid host race differentiation. [PDF]

open access: yes, 2016
Host-associated races of phytophagous insects provide a model for understanding how adaptation to a new environment can lead to reproductive isolation and speciation, ultimately enabling us to connect barriers to gene flow to adaptive causes of ...

Arbuscular mycorrhizal fungus alters the phyllosphere microbial community and modifies plant defences against co‐attack of pea aphid and pathogen

open access: yesFunctional Ecology, Volume 39, Issue 11, Page 3181-3196, November 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Arbuscular mycorrhizal fungi (AMF), pathogens and insect pests usually colonize or infect the same plant. Besides, AMF changes plant defence enzymes and metabolites under multiple biotic stresses and alters the interrelationship between plant, pathogen and insect ...

Variation in Escape Behavior of Red and Green Clones of the Pea Aphid [PDF]

open access: yes, 2018
Many insect species have evolved a number of antipredator tactics among which the animal can choose when attacked by a natural enemy. While it is known that individuals may differ in how the antipredator tactics are employed, quantitative studies are ...

Host-plant acceptance by aphids: cues initiating reproduction

open access: yes, 2011
The host-plant acceptance behaviour of aphids was examined, in two aphid species, the bird cherry-oat aphid, Rhopalosiphum padi and the pea aphid, Acyrthosiphum pisum, to elucidate the recognition factors used to assess plant suitability for ...

Genomic and cytogenetic localization of the carotenoid genes in the aphid genome [PDF]

open access: yes, 2016
Data published in the scientific literature suggests a possible link between chromosomal rearrangements involving autosomes 1 and 3 and the presence of red morphs in the peach-potato aphid Myzus persicae (Sulzer).

Natural occurrence of entomophthoroid fungi of aphid pests on Medicago sativa L. in Argentina

open access: yesRevista Argentina de Microbiología
Four species of entomophthoroid fungi, Pandora neoaphidis (Entomophthorales: Entomophthoraceae), Zoophthora radicans (Entomophthorales: Entomophthoraceae), Entomophthora planchoniana (Entomophthorales: Entomophthoraceae) and Neozygites fresenii ...

Occupancy, spatial variance, and the abundance of species [PDF]

open access: yes, 2003
A notable and consistent ecological observation known for a long time is that spatial variance in the abundance of a species increases with its mean abundance and that this relationship typically conforms well to a simple power law (Taylor 1961 ...

The chemical signatures underlying host plant discrimination by aphids

open access: yesScientific Reports, 2017
The diversity of phytophagous insects is largely attributable to speciation involving shifts between host plants. These shifts are mediated by the close interaction between insects and plant metabolites.

Parasitic wasp responses to symbiont-based defense in aphids

open access: yesBMC Biology, 2012
Background Recent findings indicate that several insect lineages receive protection against particular natural enemies through infection with heritable symbionts, but little is yet known about whether enemies are able to discriminate and respond to ...

Parasitism, Adult Emergence, Sex Ratio, and Size of \u3ci\u3eAphidius Colemani\u3c/i\u3e (Hymenoptera: Aphidiidae) on Several Aphid Species [PDF]

open access: yes, 2017
Aphidius colemani 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.
