Rapid Identification of Aphid Species by Headspace GC-MS and Discriminant Analysis

open access: yesInsects, 2023
Aphids are a ubiquitous group of pests in agriculture that cause serious losses. For sustainable aphid identification, it is necessary to develop a precise and fast aphid identification tool. A new simple chemotaxonomy approach to rapidly identify aphids

Effect of female size on host selection by a koinobiont insect parasitoid (Hymenoptera: Braconidae: Aphidiinae)

open access: yesEuropean Journal of Entomology, 2009
Body size is a main fitness component of insect parasitoids. We assessed the potential influence of maternal size of the parasitoid wasp Aphidius colemani Viereck (Hymenoptera: Braconidae: Aphidiinae) on its ability to parasitize the different instars of

Detection of Apple Hammerhead Viroid, Apple Luteovirus 1 and Citrus Concave Gum-Associated Virus in Apple Propagation Materials and Orchards in the Czech Republic and Hungary

open access: yesViruses, 2022
Grafting cultivars onto rootstocks is a widely used practice by the apple industry predominantly aimed at faster fruit bearing. Using high-throughput sequencing, we revealed the presence of recently described viral agents, namely apple hammerhead viroid (

Mating success and mating behaviour of the aphid, Myzus persicae (Hemiptera: Aphididae)

open access: yesEuropean Journal of Entomology, 2002
In this study, aspects of the reproductive performance and behaviour of male Myzus persicae (Sulzer) (Hemiptera: Aphididae) were investigated. We report that males of clones possessing an autosomal 1,3 translocation conferring insecticide resistance show

Electrostatic Insect Repulsion, Capture, and Arc-Discharge Techniques for Physical Pest Management in Greenhouses

open access: yesAgronomy, 2022
This article reviews the development of electrostatic apparatuses for controlling insect pests in greenhouses. The apparatuses control insects by repelling them, capturing them, and killing them by producing an arc discharge.

Chemical cues mediating aphid location by natural enemies

open access: yesEuropean Journal of Entomology, 2008
There is increasing evidence that chemical cues play a pivotal role in host selection by the natural enemies of aphids. We use Vinson's (1976) division of the host selection process into habitat location, host location and host acceptance for both ...

Aphid Pheromones

open access: yes, 2010
Aphids are the main insect pests of agricultural crops in temperate regions causing major economic losses. Although broad-spectrum insecticides are available for control, alternative and more targeted methods are needed due to insecticide resistance and increasing environmental pressures.

Identification of Novel Pesticides for Use against Glasshouse Invertebrate Pests in UK Tomatoes and Peppers

open access: yesInsects, 2015
To inform current and future pesticide availability to glasshouse vegetable growers, the current project trialled more than twenty products, including existing industry standards, against four key pests of glasshouse tomatoes and bell peppers.

Neophytadiene, a Plant Specialized Metabolite, Mediates the Virus‐Vector‐Plant Tripartite Interactions

open access: yesAdvanced Science, EarlyView.
Tomato chlorosis virus (ToCV) infection induces production of neophytadiene, a volatile resulting from chlorophyll degradation that is highly attractive to whiteflies. OBP2, an odorant‐binding protein from insect vector B. tabaci, exhibits a strong binding affinity for neophytadiene.

Asymptomatic Host Plant Infection by the Widespread Pathogen Botrytis cinerea Alters the Life Histories, Behaviors, and Interactions of an Aphid and Its Natural Enemies

open access: yesInsects, 2018
Plant pathogens can profoundly affect host plant quality as perceived by their insect herbivores, with potentially far-reaching implications for the ecology and structure of insect communities.
