Popis: International audience; The distance from which hosts are perceived by foraging parasitoid females has been repeatedly considered to be an important behavioural trait that is supposed to be related to their efficiency as biological control agents. In the present study, such a ‘reactive distance’ was quantified using the automatic analysis of video-recorded females' walking paths. Inter-specific variation of this trait was analysed by comparison between Aphis gossypii Glover, Myzus persicae Sulzer, and Sitobion avenae Fabricius, and three of their parasitoid species known to present different levels of specificity to these hosts: Aphelinus abdominalis Dalman, Aphidius colemani Viereck, and Aphidius picipes Nees. Responses to two different host instars of different size were also compared in each combination. On average, parasitoid females were able to perceive aphids from a distance of about 3 to 4 mm. The only significant difference observed was between the Aphelinus and the two Aphidius parasitoid species. No difference was detected between the different host instars or species tested. Females seem to be unable to discriminate between host and non-host species from a distance. These results seem to confirm the hypothesis of the use of a cuticular contact kairomone for host recognition at the species level.
