Interactions between night warming and light pollution for the different predator treatments (no predators, Col. maculata and Coc. septempunctata) in the field experiment. (Each treatment was replicated four times, for a total of 2 × 2 × 3 × 4 = 48 experimental units. Statistical analyses were performed on the log₁₀ abundance of pea aphids at the end of the 9-day experiment.)
