How to cite this collection:
The record contains information on the number of aphids and chemical footprints of two aphid species. The data was collected in field and laboratory trials, we first examined how plant microsites alter fitness by measuring the fecundity of each species. Next, we tested whether intra- and interspecific pre-inhabitation modify habitat selection in two aphid species. Then we conducted laboratory trials showed that R. maidis displaced R. padi. Through gas chromatography-mass spectrometry analysis and bioassays testing the effects of aphid density and footprint extracts, we found a density-dependent response, with R. padi avoiding locations previously inhabited by R. maidis. Chemical analysis of footprint crude extracts showed a highly abundant compound, 1-hexacosanol, and when presented as the synthetic form also elicited R. padi displacement.

Purpose
The data was collected to gain a better understanding about the role of chemical signals, cuticular compounds, on the the habitat selection of species that share the same limiting resources.
Lineage
Data was collected following the methods on "Chemical footprints mediate habitat selection in co-occurring aphids"- BEHECO-2021-0323

Data Quality Assessment Scope
Data for effect of plant microsite on the insect species fitness was compared between stem and leaf; data for effect of co-occurrence in habitat selection was compared between species alone vs. together; data for habitat preference was compared between pre-inhabited areas in conspecifics and heterospecifics; data for habitat preference in the lab was compared using experimental artificial arenas made by plastic tubes, comparing treated areas with footprint extracts and the major compound (synthetic standard).
Data Quality Report

Data Quality Assessment Outcome
Number of aphid on treated areas (pre-inhabited, treated with footprint extracts, synthetic compound, or clean area).
