Trans-generational effects of mild heat stress on the life history traits of an aphid parasitoid. [PDF]

PLoS ONE, 2013
Temperature changes are common in nature and insects are particularly exposed and sensitive to such variations which can be potential stresses, ultimately affecting life history traits and overall fitness.

Host aphid immunosuppression by Aphidius ervi venom

Entomologia Experimentalis et Applicata
AbstractThe host immunosuppression by parasitic wasps is an important component of the host regulation strategy. The venom injected at the oviposition is one of the key‐factors involved in this host alteration and, in some parasitoids, its immunosuppressive role is complemented by wasp's symbionts.

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,

Cereal aphids (Hemiptera: Aphidoidea) in Serbia: Seasonal dynamics and natural enemies

European Journal of Entomology, 2008
During 1989-2006 the number of live aphid, mummies, aphid specialist predators and their parasitoids in cereal fields in Serbia were recorded. S. avenae and M. dirhodum were the most common, both on wheat and rye crops.

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,

Improvement in the cold storage of Aphidius ervi (Hymenoptera: Aphidiinae)

EUROPEAN JOURNAL OF ENVIRONMENTAL SCIENCES, 2011
Biological control is beginning to be more commonly used, especially in greenhouses. The inundatory release of insects, especially parasitoids, requires a thorough knowledge of their biology and of mass-rearing techniques. Moreover, to synchronize releases with host presence, the parasitoids have to be kept in cold storage.

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.

Responses to aphid sex pheromones by the pea aphid parasitoids Aphidius ervi and Aphidius eadyi

Entomologia Experimentalis et Applicata, 1999
Abstract Aphidius ervi and Aphidius eadyi, two parasitoids of the pea aphid Acyrthosiphon pisum, were attracted to components of the aphid sex pheromone in laboratory bioassays. Pre‐test experience with host aphids in the presence of aphid sex pheromone did not affect the response of A.

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 ...

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 ...
