Legume‐Colonising Aphids as Potential PNYDV‐Vectors: Reproduction and Infestation Dynamics in Two Different Field Bean Varieties

Journal of Applied Entomology, Volume 149, Issue 3, Page 442-451, April 2025.
ABSTRACT Faba bean can be infected by Pea necrotic yellow dwarf virus (PNYDV), a novel pathogen throughout Europe, and transmitted persistently by several legume‐colonising aphid species. Recent field screenings in Austria and Germany of different faba bean varieties were encouraging as consistently the lowest viral symptom development in the variety ...

A survey of alfalfa aphids and their natural enemies in Isfahan, Iran, and the effect of alfalfa strip-harvesting on their populations [PDF]

نامه انجمن حشره‌شناسی ایران, 2010
During a two-year (2004-2005) survey of alfalfa aphids and their natural enemies in Isfahan, a total of four aphid species and 58 species of their natural enemies comprised of 45 predatory species, 11 parasitoid species and two species of parasitic mites

Common mycorrhizal networks enhance defense responses against pathogens in neighboring plants

iMetaOmics, Volume 2, Issue 1, March 2025.
The common mycorrhizal networks (CMNs) provide a channel for interplant communication, which enables plants of different species to prepare for pathogen infections without direct exposure. The CMNs change the microbial abundance and community structure of the neighboring plants following pathogen infection in the donor plants, which further enhances ...

Study of anatomical changes in Coccinella septempunctata induced by diet and by infection with the larva of Dinocampus coccinellae using magnetic resonance microimaging

European Journal of Entomology, 2000
A range of nuclear magnetic resonance (NMR) techniques, 1H liquid spectroscopy and T1 and T2 relaxation measurements, and microimaging, have been used to observe changes taking place within the bodies of live samples of Coccinella septempunctata, under a

Endophytic entomopathogenic fungi as biological control agents of insect pests

Pest Management Science, Volume 80, Issue 12, Page 6033-6040, December 2024.
Interaction between plants and endophytic entomopathogenic fungi. Fungal metabolites and induced systemic resistance enhance the plant's defense mechanisms against pests and pathogens. In addition, volatile compounds emitted by the plants colonized by endophytic entomopathogenic fungi play an important role in recruiting natural enemies of insect pests,

Amino acid-mediated impacts of elevated carbon dioxide and simulated root herbivory on aphids are neutralized by increased air temperatures [PDF]

, 2014
Changes in host plant quality, including foliar amino acid concentrations, resulting from global climate change and attack from multiple herbivores, have the potential to modify the pest status of insect herbivores.

Seasonal food of Ceratomegilla notata (Coleoptera: Coccinellidae) in mountain environments of Northern Italian Alps

European Journal of Entomology, 2005
The aim of this study was to clarify the diet of Ceratomegilla notata (Laicharting), a common species in different mountain habitats of the Palearctic region. In Italy it is found only in alpine ecosystems between 800-1700 m. In these areas, up to 1200 m,

Influence of intercropping with spring cereals on the occurrence of pea aphids (Acyrthosiphon pisum Harris, 1776) and their natural enemies in field pea (Pisum sativum L.)

Plant Protection Science, 2011
Occurrences of pea aphids and their natural enemies (syrphids, mummies caused by entomopathogenic fungi Beauveria sp. and by the parasitic wasp Aphidius ervi) were compared in monocultures and mixtures of field peas and spring cereals in three seasons ...
