Article Synopsis
- Aphids, specifically the bird cherry-oat aphid, are significant agricultural pests, and populations in central Chile show low genetic diversity with a few dominant genotypes.
- Researchers collected and analyzed aphids from various cereal crops, revealing that one "superclone" genotype made up about half of all samples, thriving across different cereal hosts.
- Findings indicate that obligate parthenogenesis (asexual reproduction) is likely the main reproductive strategy for these aphids in Chile, suggesting their introduction involved a limited number of successful genotypes.
Poplars are frequently attacked by aphids. The differential susceptibility of poplar hybrids to the aphid Chaitophorus leucomelas Koch (Sternorrhyncha: Aphididae) has been described, but the mechanism underlying this pattern is unknown. This work tested the hypothesis that poplar resistance to this aphid is associated with the presence of volatiles and secondary plant compounds that affect host selection and feeding behavior.
