Yet, learning rate and memory retention can vary greatly across or even within species. While interspecific differences have been attributed to ecological context or life history constraints, intraspecific variability in learning behavior is rarely studied and more often, ignored: inferences of the cognitive abilities of a species are most of the time made from experiments using individuals of a single population. Here, we show that learning of host-associated cues in the parasitic wasp Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae) shows considerable interpopulation variability, which is at least partly, genetically determined. The strengths of the learning response differed predictably between populations and also varied with the rewarding stimulus. We tested memory retention in a genetically diverse strain and in an iso-female line, bearing a low genetic variability. In addition, we compared our findings with published studies on a third strain using a meta-analytical approach. Our findings suggest that all three strains differ in memory formation from each other. We conclude that, even though the associative learning of host cues is most likely under strong natural selection in parasitoid wasps, considerable genetic variability is maintained at the population as well as at the species level in N. vitripennis.
