学习能力与能量消耗有关，这通常通过在广泛的发育、生理和生活史特征中进行权衡而变得明显。与学习能力相关的成本可以是构成性的，也可以是诱发性的，这取决于它们是总是发生的，还是只有在积极学习和记忆信息时才会发生。使用线的寄生蜂Nasonia vitripennis，选择快速联想学习能力，我们评估了一系列的特点，以前已被确定为潜在的成本与学习。在选定的品系和对照品系之间没有观察到寿命、脂质储备、胫骨长度、卵负荷或繁殖力的差异。在本研究的设置中，所有这些特征都被认为可能导致构成性成本。在两种形式的放松选择后，逐渐逆转到基线学习，表明学习能力的构成成本很小。我们还测试了在后期形成的其他记忆类型的权衡，但没有发现任何证据表明选择的中期记忆会导致其他记忆类型的表现下降。总之，我们只观察到一个构成成本的一个小的影响，没有其他的成本和权衡，在文献中报道的是在这种情况下的重要价值。因此，我们主张在学习能力的成本和效益研究中更好地纳入生态和经济成本。
Learning ability has been associated with energetic costs that typically become apparent through trade-offs in a wide range of developmental, physiological, and life-history traits. Costs associated with learning ability can be either constitutive or induced, depending on whether they are always incurred or only when information is actively learned and memorized. Using lines of the parasitoid waspNasonia vitripennisthat were selected for fast associative learning ability, we assessed a range of traits that have previously been identified as potential costs associated with learning. No difference in longevity, lipid reserves, tibia length, egg load, or fecundity was observed between the selected and control lines. All of these traits are considered to potentially lead to constitutive costs in the setup of this study. A gradual reversal to baseline learning after two forms of relaxed selection was indicative of a small constitutive cost of learning ability. We also tested for a trade-off with other memory types formed at later stages, but found no evidence that the mid-term memory that was selected for caused a decrease in performance of other memory types. In conclusion, we observe only one minor effect of a constitutive cost and none of the other costs and trade-offs that are reported in the literature to be of significant value in this case. We, therefore, argue for better inclusion of ecological and economic costs in studies on costs and benefits of learning ability.
