Low sex drive and choosy females: Fungal infections are a reproductive downfall for male house flies

Many entomopathogenic fungi cause infections that kill their insect host. Little is understood about changes in the reproductive investment that occur during an infection by a lethal disease over the waning life of an insect. Life history theory suggests the host will respond by investing resources into fighting the disease or increasing reproduction. Here, we investigate how the reproductive life of adult house flies, Musca domestica, is impacted by its host-specific fungal pathogen, Entomophthora muscae. Specifically, we test how the week-long infection alters the mating behavior of virgin adult male house flies. We find that the pathogen significantly decreases male libido; an effect which grows stronger over the course of the infection. Furthermore, females were significantly less likely to choose an infected male, reducing male mating success. Additionally, we assessed sperm viability to understand the reproductive costs for monandrous females to mate with infected males.

There are nine annotated datasets: Activity.csv, Male_Housefly_Weight.csv, Virulence.csv, MatingLatency.csv, FemaleChoice.csv, Mating_Attempts_Duration.csv, SpermViability.csv

## Description of the data and file structure

The Activity.csv dataset was used in locomotion analyses and to generate Figures 1a, S3a and S4.

Table of contents for Activity.csv

* Individual: unique ID formed of the concatenation of variables Subject, Time and Week (see below) - (this variable was not used in this study)
* Subject: ID code for for each individual fly per weekly batch, indicating treatment status (infected or control) and its assigned number - (this variable was not used in this study)
* Time: number of hours after house flies were first placed with sporulating or freeze-killed cadavers
* Video: video number of the day, where 1 = 9am, 2 = noon and 3 = 3pm
* dpi: day post infection...
