亮点 Nasonia 品系在学习和记忆刺激的程度方面存在差异。尽管存在显着的种内差异，但物种之间没有差异。记忆保留模式是品系特异性的，并且在刺激模式之间相似。个体品系不能代表物种水平的认知能力。昆虫物种在学习和记忆保留方面表现出大范围的种间和种内差异。据报道，寄生蜂 Nasonia 属的三个物种的联想学习能力存在差异，最显着的是 Nasonia vitripennis 和 Nasonia giraulti 之间的差异，已经建立了近交同基因株并对其进行了深入研究。我们解决了此类同基因菌株的学习和记忆如何与这些物种的遗传多样性菌株中发现的表型进行比较的问题。我们记录了两个物种的同基因菌株和遗传多样性菌株在嗅觉或视觉调节后 4-120 小时的记忆保留情况。记忆保留通常会随着时间的推移而下降，但不同菌株的下降模式始终不同。同基因的 N. vitripennis 菌株形成了持久（> 5 天）的记忆，而等基因的 N. giraulti 菌株在 48 小时后失去了记忆。然而，这两个物种的遗传多样性菌株形成了持久的记忆。所有菌株的记忆保留模式均独立于条件刺激的感觉方式。这些结果表明，两个物种的联想学习和记忆存在差异，但记忆保留方面没有明显的种间差异。如果不能更好地了解物种内学习能力的自然变异，个体菌株，尤其是遗传变异性较低的同基因菌株，不一定能代表整个物种。
HighlightsNasonia strains differ in how well stimuli are learned and memorized.Despite significant intraspecific variation, there is no difference between species.Memory retention pattern is strain specific and similar across stimulus modalities.Individual strains are not representative of species level cognitive abilities.Insect species display a large range of inter-and intraspecific variation in learning and memory retention. Variation in associative learning ability has also been reported for three species in the parasitoid wasp genus Nasonia, most notably between Nasonia vitripennis and Nasonia giraulti, for which inbred isogenic strains have been established and studied intensively. We addressed the question how learning and memory of such isogenic strains compare to the phenotypes found in genetically diverse strains of these species. We recorded memory retention of both isogenic and genetically diverse strains of two species at 4–120 h after either olfactory or visual conditioning. Memory retention typically declined over time, but the pattern of decline differed consistently between strains. The isogenic N. vitripennis strain formed long-lasting (> 5 days) memory, whereas the isogenic N. giraulti strain lost its memory after 48 h. Yet, genetically diverse strains of both species formed long-lasting memory. Memory retention patterns of strains were independent of sensory modality of the conditioned stimulus for all strains. These results show that there is variation for associative learning and memory within the two species, but not clear interspecies differences in memory retention. Without a better overview of the natural variation in learning abilities within a species, individual strains, especially isogenic strains with low genetic variability, are not necessarily representative of the species in general.
