Data for: Oviposition fluids mediate larval competition

# Data for: Oviposition fluids mediate larval competition [https://doi.org/10.5061/dryad.37pvmcvrm](https://doi.org/10.5061/dryad.37pvmcvrm) ## Description of the data and file structure Data set contains details, primarily counts, resulting from dissection of injected *P. rapae* caterpillar hosts. Common abbreviations used: * Cg = Cotesia glomerata * Cr = Cotesia rubecula * Treatment names: cv - calyx + venom, c - calyx only, cr - C. rubecula parasitized, pbs - pbs only, v - venom only * CgL = C. glomerata larva File descriptions (including column headers without clear titles): "CgCV injection data" is dissection data from hosts injected with C. glomerata oviposition fluids and associated controls. Hosts were parasitized by C. rubecula * Trt - injection treatment * Rep - replicate number * Cr present - y/n C. rubecula larva present * Deform/dead - y if C. rubecula does not appear to be developing normally and alive "CrCV injection data" is dissection data from hosts injected with C. rubecula oviposition fluids and parasitized by C. glomerata (and associated controls) * Small eggs - number of underdeveloped C. glomerata eggs * Big eggs - number of C. glomerata eggs that had swelled and begun developing * Film eggs/film larva - respective number of C. glomerata appearing to have film developed as described in manuscript * Encapsulation - yes or no whether there was visible evidence of encapsulation during dissection (primarily melanization) * rubecula - number of C. rubecula larva in this host. Used to confirm Cr parasitism and look for multiparasitism "Cg dissection larval size data" is the dataset associated with C. glomerata immature size data (areas and lengths). Data was obtained using Nikon Elements software using a Nikon SMZ18 microscope with DS-Fi2 camera. Each row is an individual C. glomerata larva or egg with the picture file name (source), treatment, replicate, host ID (caterpillar), Cg larva/egg rep (CgL), stage of development (stage), presence of film or deformities, and length (um) and area (um^2).
