Although the influence of possible genotypic variation between A. Discussion Our study provides the first comprehensive reference transcriptome for the aphid parasitoid wasp Aphidius ervi obtained from females reared on three different aphid hosts: This difference seems to persist even after the different wasp populations were reared on the same aphid host in the laboratory for more than 50 generations.

Deep sequencing identifies viral and wasp genes with potential roles in replication of Microplitis demolitor Bracovirus. One way to do this is the formation of host races, i. University of California Press; Berkeley: National Center for Biotechnology InformationU.

Differential gene expression analysis The insect filtered, non-redundant reference transcriptome was used as a basis for differential gene expression studies between tissues separate for head and body Fig.

One of the most widely used species in biological control programs is Aphidius ervi, a worldwide distributed koinobiont endoparasitoid of several Macrosiphinae aphid species such as the pea aphid Acyrthosiphon pisum Henry et al.

A recent study showed significant differences in host preference and host acceptance infectivity depending on the host A. Chemical use Ervi is sensitive to many pesticides, particularly pyrethroids, organophosphates aphidiuw neonicotinoids.

The GO Term enrichment analysis was performed between differentially expressed genes and indicated the most enriched GO terms for bodies and heads Fig. We found several significantly differentially expressed genes involved in chemical perception between our three A. Assembly, assessment, and availability of De novo generated eukaryotic transcriptomes.


The wasp Aphidius ervi, a generalist koinobiont parasitoid of aphids, was introduced from Europe into Chile in the late s to control agriculturally important aphid species. The genes emphasized in this study deserve special attention for future research in order to prove their role in host preference and host selection by A. Support Center Support Center.

Acceptance and suitability of Acyrthosiphon pisum and Sitobion avenae as hosts of the aphid parasitoid Aphidius ervi Hymenoptera: However, it is ervl how much phenotypic plasticity the parasitoid needs to exploit different hosts or whether they can use identical mechanisms and strategies when parasitizing different hosts.
