dc.description.abstractPlants undergoing insect infestation release herbivore-induced plant volatiles (HIPVs) into their environment, which are then used by natural enemies for their benefit. The pest Aleurothrixus floccosus, which affects citrus orchards in northern Chile, specifically at Pica Oasis, poses a year-round threat. Recently, the introduction of the exotic ladybird Clitostethus arcuatus has been noted as a predator of A. floccosus. This study delved into how HIPVs emitted from tangelo (Citrus reticulata × C. ×paradisi Macfad.) and lime (C. ×aurantifolia (Christm.) Swingle) infested-shoots impact the behavioral responses of C. arcuatus. The volatile compounds were collected using the headspace technique, revealing notable qualitative changes after herbivory. In two-choice bioassays, the HIPVs elicited an attractive response in C. arcuatus compared to A. floccosus. At concentrations of 10 and 100 μg mL-1, the predators displayed a distinct preference for methyl salicylate (MeSA). These findings underscore that C. arcuatus exploits the HIPVs emitted from citrus infested-shoots, fostering tritrophic interactions. Exploring the impact of whitefly attacks on other fruit trees, emerges as a significant avenue for future investigation.es_ES
