Aphidius ervi will consume all types of larger aphids, especially the potato aphid, Macrosiphum euphorbiae, and the glasshouse potato aphid, Aulacorthum. Erviline biological control agent contains the Braconid wasp, Aphidius ervi. It stings and parasitizes larger aphids, such as the foxglove aphid, Aulacorthum. Aphidius ervi. Type of insect: Wasp. Kingdom Animalia, Phylum Arthropoda, Class Insecta, Order Hymenoptera, Family Aphidiidae. How to identify it: Mummies.

For the correct approach, you should always consult a Koppert specialist or a recognised distributor of Koppert products. As contigs can be assigned to more than one GO category, 14, contigs were assigned to biological process, 7, contigs were classified under molecular function, and 5, were classified in cellular component Fig. Host switching in erci generalist parasitoid: Additionally, our experimental setup allowed us to identify differentially expressed genes between A. Chemical use Ervi is sensitive to many pesticides, particularly pyrethroids, organophosphates and neonicotinoids.

We thank Francisca Zepeda-Paulo for providing A. Host specialization in habitat specialists and generalists.

Our study provides the first comprehensive reference transcriptome for the aphid parasitoid wasp Aphidius ervi obtained from females reared on three different aphid hosts: Also available in bulk quantities in bottles containing mummies in buckwheat from which 5, parasitic wasps emerge. We found several differentially expressed odorant binding proteins and olfactory receptor proteins in particular, when we compared parasitoids from different host species.

University of California Press; Berkeley: These inbred lineages were propagated for approximately 60 generations before samples were taken for the RNAseq experiments. Table 1 Summary of Aphidius ervi transcriptomic libraries and assembly statistics. The sequence with the highest BitScore was considered as the best blast hit, selected and designed as an annotated contig Ono et al.

These venom proteins are injected into the ervk at oviposition and would have a role in the modulation of the aphid physiology by inducing apoptosis of host ovaries and arresting host reproduction Colinet et al.

Journal List PeerJ v. The relationship between host selection behaviour and offspring fitness in a koinobiont parasitoid. Journal of Chemical Ecology. Interestingly, both Ae-AP populations APA and APP had a higher number of up-regulated chemosensory genes and neuronal-related genes compared to Ae-SA Table 3 —additional file 1which is similar to that observed in other insect species capable of using different hosts, such as in the Mediterranean corn borer Sesamia nonagrioides Glaser et al.

It would be interesting to see whether and how many of the differentially expressed genes underlying the observed host related differences in A. Ervi is primarily used in greenhouse production, but can also be used in outdoor aphidkus to get parasitoids started earlier than would occur naturally.

Discussion Our study provides the first comprehensive reference transcriptome for the aphid parasitoid wasp Aphidius ervi obtained from females reared on three evri aphid hosts: Braconidae, Aphidiinae for biological control of aphids in Chile. Developmental plasticity and evolution.

The abilities of the aphid parasitoids Aphidius ervi Haliday and A. Support Center Support Center. Crispo Crispo E. Read count table mapped and sample correlation matrix— A.

When to release Ervi works best when used preventatively, or when aphids are first noticed in a crop. Place the vial underneath the canopy of the crop and allow the adults to fly out of the vial. In the case of the SA lineage both for heads and bodiesa contig was considered as overexpressed only if its expression profile was 4-fold times higher when compared to both APA and APP populations. We found aphiidius significantly differentially expressed genes involved in chemical perception between our three A.

Additional Information and Declarations Competing Interests The authors declare there are no competing interests. Table 3 Expression patterns of transcripts involved in chemoperception between Aphidius ervi populations reared on their natal hosts.

Each week, new aphid infested plants were introduced into the A. Crops We work in a range of crops and have developed biologically based IPM programs to control the major pests.

Genes eervi had at least 4-fold change values with a FDR-corrected p -value of 0. The proximal mechanisms of A. Thus, three different and highly inbred A. Here, we determined the effect of aphid host species Sitobion avenae versus Acyrthosiphon pisum reared on two different host plants alfalfa and pea on the transcriptome of adult A.

We found a large number aphodius differentially expressed genes between host species: One way to test between these options is to compare the transcriptomes of A. The GO Term enrichment analysis was performed between differentially expressed genes and indicated the most enriched GO terms for bodies and heads Fig.
