Aphid Symbiont Effects on Fecundity and Fungal Pathogen Resistance

A 2020 dataset from Piotr Łukasik investigates the effects of facultative endosymbiotic bacteria on aphid hosts. It measures aphid fecundity and susceptibility to an entomopathogenic fungus across multiple host genotypes and species, with symbionts transferred either together or separately. The study explores how protective phenotypes conferred by Rickettsia and Spiroplasma vary among host backgrounds and are influenced by co-infection with Hamiltonella.

Use Cases

• Analyze aphid fecundity variation across different symbiont infection types (single vs. double) and host genotypes.
• Model the pathogen-protective phenotype conferred by Rickettsia and Spiroplasma symbionts against an entomopathogenic fungus.
• Investigate the interaction effect between co-infecting symbionts, such as Hamiltonella with Rickettsia or Spiroplasma, on host susceptibility.
• Compare symbiont effects across host species, specifically Acyrthosiphon pisum and Sitobion avenae, as indicated in the tags.

Strengths

• Data originates from a controlled experimental study involving symbiont transfer into novel host genotypes.
• Investigates a multi-factorial design including two aphid species, five host genotypes, and multiple symbiont combinations.
• Published under a permissive CC0 1.0 license, facilitating unrestricted reuse.

Limitations

• The dataset's size, row count, column structure, and file formats are unspecified, limiting assessment of its scale and structure.
• As a biological experiment, the sample size for each treatment combination is unknown and may be limited.
• The data is from a specific 2020 study, so findings may not generalize to other ecological contexts or symbiont systems.
