Intraguild predation between psyllophagous ladybird

This dataset compiles data related to intraguild predation among four species of psyllid-eating ladybirds found on La Réunion Island. The study was conducted to evaluate a biological control program against Acizzia uncatoides, an invasive psyllid species from Australia, using Harmonia conformis, a predatory ladybird not present in Réunion. The data are divided into two studies: one conducted in an olfactometer and the other in a petri dish choice experiment.
