Table 1 Compilation of the two behavioral and eight biological parameters of the spotted-wing drosophila (Drosophila suzukii) addressed in this study, showing the effect of larval intraspecific competition (IC) on each parameter when insects display pupation attached to and detached from a blueberry fruit.

  1. “+” = Positive effect (e.g., IC increases the rate of detached pupation).
  2. “−” = Negative effect (e.g., IC decreases the rate of attached pupation).
  3. “0” = Neutral effect (e.g., IC does not affect the pupa-adult period of individuals that were found detached from the fruit).
  4. N/A = Not applicable.
