Plant-to-Plant Communication Mediating In-Flight Orientation of Aphidius ervi

Journal of Chemical Ecology, 2002
Broad bean plants (Viciafaba) infested by the pea aphid, Acyrthosiphonpisum, play akey role in the in-flightorientation of the parasitoidAphidius ervi, by producing host-induced synomones (HIS). These volatiles are herbivore-specific and are systemically released from insect-free parts of an infested plant, suggesting the existence of an elicitor ...

An ‘artificial aphid’ for Aphidius ervi (Hym., Braconidae)

Journal of Applied Entomology, 2005
Abstract:  An artificial aphid was developed by making parafilm® bubbles filled with aphid haemolymph and its suitability for parasitoid oviposition was tested. Aphidius ervi accepted the parafilm® aphid and laid eggs on it. By stretching, the thickness of the parafilm could be changed.

Nutrient absorption by Aphidius ervi larvae

Journal of Insect Physiology, 2005
It is well documented that in the model system Aphidius ervi Haliday (Hymenoptera, Braconidae)/Acyrthosiphon pisum (Harris) (Homoptera, Aphididae) host regulation by the parasitoid larva induces in the aphid haemolymph major changes of the titer of nutritional compounds such as proteins, acylglycerols and free amino acids, in order to meet the stage ...

Aphidius ervi teratocytes release an extracellular enolase

Insect Biochemistry and Molecular Biology, 2009
We report the cloning of a gene and the characterization of the encoded protein, which is released by the teratocytes of the parasitoid Aphidius ervi in the haemocoel of the host aphid Acyrthosiphon pisum. The studied protein was identified by LC-MS/MS, and the gathered information used for isolating the full length cDNA.
