ANOVA statistics of fecundity data for experiments where aphids from different clonal lines (2a: 5A, G3, G6, LSR1) or with different symbionts (2bi: no symbiont, Hamiltonella defensa, Regiella insecticola, Serratia symbiotica; 2bii: no symbiont, Regiella insecticola; 2biii: 5A and LSR1 with no symbiont, or Regiella insecticola) exposed to the alarm pheromone EBF or hexane as a control. (2c) GLM statistics of the proportion of time aphids were either on their plant, or active after exposure to EBF, hexane or water. |
