Common endosymbionts influence host sexual selection by shaping mating preferences via altered chemical communication

The File A contains raw data from mating preference experiments in Pezothrips kellyanus, investigating female and male mate choice across three different endosymbiont association types: U (endosymbiont-free), C (Cardinium), and CW (Cardinium and Wolbachia).Sheet 1: Female mating preference tests (first approach, mate switch and mate choice outcomes).Sheet 2: Males forewing size measurements from the female mating preference tests (to control for body size).Sheet 3: Male mating preference tests (first approach, mate switch and mate choice outcomes).Sheet 4: Female forewing size measurements from the male mating preference tests.The File B dataset contains raw cuticular hydrocarbon (CHC) profiles extracted from male Pezothrips kellyanus with three different endosymbiont association types (endosymbiont-free, Cardinium, and Cardinium and Wolbachia). CHCs were extracted using n-hexane and analysed via gas chromatography–mass spectrometry (GC-MS) with an Agilent 7890 GC and 5975 MSD. CHC identification was based on retention indices and diagnostic fragmentation patterns, using the NIST 23 library. Peak areas were normalized to an internal standard (dodecane) and log₁₀-transformed. These data were collected to investigate chemical cues involved in mate choice among endosymbiont association types.
