Fig. 3

Attraction (a, b) and oviposition (c, d) responses of Ph. papatasi to different doses of conspecific eggs. Top panels (a, c) depict the least square regression lines of oviposition site preferences (± SE) of the best-fit models, based on attraction (a) or oviposition (c), against conspecific egg mass (mg) ((log x)+1 transformed). Horizontal dashed line crossing through the preference value of 0.5 indicates no preference with values above or below this line indicating positive or negative effects of conspecific eggs, respectively. Bottom panels (b, d) depict mean (± SE) abundance of females trapped (b) or eggs laid (d) in control and treatment oviposition cups, respectively. Also shown are the odds (with their respective 95% CI and P-value) of females trapped or eggs laid in the treatment cup compared with the control cup
