| comparative genetics of invasive populations of walnut aphid, chromaphis juglandicola, and its introduced parasitoid, trioxys pallidus, in california. | coevolution may be an important component of the sustainability of importation biological control, but how frequently introduced natural enemies coevolve with their target pests is unclear. here we explore whether comparative population genetics of the invasive walnut aphid, chromaphis juglandicola, and its introduced parasitoid, trioxys pallidus, provide insights into the localized breakdown of biological control services in walnut orchards in california. we found that sampled populations of c. ... | 2018 | 29321915 |
| nitrogen-mediated interaction: a walnut-aphid-parasitoid system. | the effects of plant quality on natural enemies are often overlooked in planning and executing biological control programs for insect pests in agriculture. plant quality, however, could help to explain some of the observed variation in effectiveness of biological control, as it can indirectly influence natural enemy populations. in this study, we used the walnut aphid chromaphis juglandicola (kaltenbach) to address the effect of increased nitrogen availability to the host plant on parasitism by ... | 2016 | 27271943 |
| imsat: a novel approach to the development of microsatellite loci using barcoded illumina libraries. | illumina sequencing with its high number of reads and low per base pair cost is an attractive technology for development of molecular resources for non-model organisms. while many software packages have been developed to identify short tandem repeats (strs) from next-generation sequencing data, these methods do not inform the investigator as to whether or not candidate loci are polymorphic in their target populations. | 2014 | 25281214 |
