The two accompanying files contain data for the paper by Sy et al. The file 'expt12_female_survival_data' contains data on the survival of adult female mosquitoes from Experiment 1 and 2. The file 'expt1_fecundity_blood_data' contains data from the Experiment 1 related to female fecundity and blood feeding. In the file 'expt12_female_survival_data' the following column headings refer to: experiment - the first or second of the two experiments cage - the number of each cage within each experiment in which the female was housed treatment - refers to the blood-feeding treatment experienced by females within each cage treat.replicate - refers to the replicate number for each blood-feeding treatment in Experiment 2 males.infected - describes whether the males within a cage were infected (y) or not (n) by Vavraia culicis time - the number of days post-blood feeding when adult females died or were censored censor - females that died were not censored (0), females that were censored (1) were those still alive at the end of the sampling period or removed from cages during Experiment 2 due to not having taken blood when given the opportunity to do so the previous day eppendorf - the number of the individual 1.5ml vial in which the female was put within each experiment spores.observed - the number of spores observed and counted per individual total.spores - the estimated total number of spores per individual based on the number observed indiv.infected - whether the individual female was classed as infected (y) or not (n) based on the presence/absence of spores left.wing.mm - the length of a female's left wing in mm, where measured right.wing.mm - the length of a female's right wing in mm, where measured mean.wing.mm - the average length of a females' wings when both measured In the file 'expt1_fecundity_blood_data' the following column headings refer to: cage - the number of each cage in Experiment 1 in which the female was housed males.infected - describes whether the males within a cage were infected (y) or not (n) by Vavraia culicis time - the number of days post-blood feeding when the female died. NB these females where held in individual tubes without access to sugar-water after blood feeding eppendorf - the number of the individual 1.5ml vial in which the female was put spores.observed - the number of spores observed and counted per individual total.spores - the estimated total number of spores per individual based on the number observed indiv.infected - whether the individual female was classed as infected (y) or not (n) based on the presence/absence of spores digested.blood - whether dark spots of digested blood where observed (+) or not (-) in the female's tube total.eggs - the total number of eggs developed by the female; this total includes eggs laid and those retained retained.eggs - the number of eggs retained by females at the time of their death blood.OD.1 - the first reading for the optical density of digested blood blood.OD.2 - the second reading for the optical density of digested blood mean.blood.OD - the average reading for the optical density of digested blood volume.blood.muL - the estimated volume of blood taken by the female in millilitres left.wing.mm - the length of a female's left wing in mm, where measured right.wing.mm - the length of a female's right wing in mm, where measured mean.wing.mm - the average length of a females' wings when both measured
