Determinants of variation in the response of the aphid parasitoid Aphidius ervi to aphid sex pheromones [PDF]

, 2008
Variation in parasitoid responses to semiochemicals may be influenced by genetics, phenotypic plasticity and the individual\u27s physiological state. Previous experimental work has indicated a high degree of variability among parasitoid individuals in ...

Metabolite‐based resistance in wheat varieties to aphid virus vectors: progress and future opportunities

Pest Management Science, Volume 81, Issue 11, Page 7276-7287, November 2025.
Sitobion avenae and Rhopalosiphum padi are major pests on wheat. Natural product‐based aphid resistance holds promise for the sustainable control of these pests. The current literature is discussed, highlighting knowledge gaps and challenges that need addressing. Abstract Cereal aphids, Sitobion avenae and Rhopalosiphum padi, cause severe yield loss in

Olfactory conditioning in mate searching by the parasitoidAphidius ervi(Hymenoptera: Braconidae) [PDF]

Bulletin of Entomological Research, 2008
AbstractDespite the fact that insect learning capacity has been broadly demonstrated, the role that this process plays during mate searching has been scarcely explored. We studied whether the sexual behaviour of a male parasitic wasp can be conditioned to the odours from two alternative host plant complexes (HPCs) present during its first copulation ...

Extracellular Vesicles in Arthropods: Biogenesis, Functions, Isolation Methods and Applications

Journal of Extracellular Vesicles, Volume 14, Issue 9, September 2025.
ABSTRACT Extracellular vesicles (EVs) are membrane‐bound nanoparticles secreted by cells that are involved in multiple forms of intercellular communication and show promising potential for biotechnological applications. Arthropod‐derived EV research remains relatively fragmented in contrast to the extensively studied mammalian EV field. In this review,

Strategies involved in the location of hosts by the parasitoid Aphidius ervi Haliday (Hymenoptera : Braconidae : Aphidiinae)

, 1998
The parasitoid Aphidius ervi Haliday uses both semiochemical and physical cues to locate and recognize its main host, the pea aphid Acyrthosiphon pisum (Harris). In wind tunnel studies, it was demonstrated that plant volatiles, particularly those induced

Electrophysiological and behavioural responses of Aphidius ervi (Hymenoptera: Braconidae) to tomato plant volatiles

, 2009
Flight responses of the aphid parasitoid Aphidius ervi to tomato volatiles have recently demonstrated that different plant stresses can lead to increases in attractiveness for this parasitoid.

Host specificity and host stage preference of Psyllaephagus species (Hymenoptera: Encyrtidae) towards invasive eucalypt psyllids (Hemiptera: Aphalaridae)

Agricultural and Forest Entomology, Volume 27, Issue 3, Page 463-475, August 2025.
Abstract Invasive eucalypt psyllids pose a threat to the long‐term production of eucalypts worldwide. In order to reduce their economic impact, classical biological control using Psyllaephagus species has been used successfully. The objectives of this study were to determine the host specificity and host stage preference of Psyllaephagus blastopsyllae,

Facultative endosymbionts of aphids on strawberry crops affect aphid-parasitoid interactions

Biological Control
Aphids are major agricultural pests and laboratory studies have shown that heritable bacterial endosymbionts can protect aphids against biocontrol parasitoids, but results from agricultural crop systems are lacking. Here we assess (1) which aphid species

What is the potential for artificial selection of insect biological control traits? A systematic review of their genetic variation, heritability, and evolvability

Entomologia Experimentalis et Applicata, Volume 173, Issue 6, Page 463-497, June 2025.
Growing interest in optimizing biocontrol traits, particularly due to Nagoya Protocol constraints, necessitates understanding their heritability and genetic variation. This systematic review of 5209 studies on arthropod biocontrol agents yielded 94 relevant articles, with 42 providing heritability values.

Melanaphis sacchari/sorghi complex: current status, challenges and integrated strategies for managing the invasive sap‐feeding insect pest of sorghum

Pest Management Science, Volume 81, Issue 5, Page 2427-2441, May 2025.
We have assembled a group of scientists that work on different aspects of SCA and hereby submit a comprehensive review of the species and its management, with ideas for future research avenues. We believe this review will be of interest to scientists studying plant–insect interactions, and extension entomologists, among others, who work with the ...
