项目摘要

Learning ability of insects has long held the interest of evolutionary biologists because of its adaptive significance. Although there are obvious benefits to learning, much variation exists in learning speed and how long a memory will last. It is generally assumed that these differences in learning evolve in response to specific environmental conditions like variability of the environment and how reliable available information is. However, our understanding of the environmental and insect-intrinsic factors which drive selection for a particular learning style is still rudimentary. The proposed project addresses this gap of knowledge by using the parasitic wasp Nasonia vitripennis as a model. The project aims to elucidate how (i) the reliability and variability of environmental information affect the evolution of learning style, and (ii) whether certain learning styles co-evolve with particular behavioural syndromes (i.e. suites of behavioural traits). Learning styles will be categorized by the readiness to learn (slow/fast learner), the maintenance of memory (short/long-term), and the accuracy of employing learned information. We will use an experimental evolutionary set-up in which parasitic wasps will evolve different learning styles in response to different artificial environments that we control for the level of variability and reliability of information. There is a direct link between learning style and fitness as the learning style will determine how successful a wasp is in finding hosts (fly pupae) in a specific environments. The number of colours of the environment in which hosts are offered and the reliability of host occurrence linked with a particular colour will vary. We will monitor: (a) the emerging learning styles in each environment in learning assays; (b) the foraging success of different learning styles in different environments; (c) whether co-evolution of learning style and behavioural syndrome occurs. These conditions will be monitored for the duration of the experiment (minimally 15 generations). This set-up will provide information on costs and benefits of a learning style, and provide insight in the evolution of learning styles in insects.

昆虫的学习能力因其适应性意义而长期以来一直引起进化生物学家的兴趣。尽管学习有明显的好处，但学习速度和记忆持续时间存在很大差异。人们普遍认为，学习中的这些差异是随着特定环境条件（例如环境的变化以及可用信息的可靠性）而演变的。然而，我们对推动特定学习方式选择的环境和昆虫内在因素的理解仍然很初级。拟议的项目通过使用寄生黄蜂 Nasonia vitripennis 作为模型来解决这一知识空白。该项目旨在阐明（i）环境信息的可靠性和可变性如何影响学习风格的演变，以及（ii）某些学习风格是否与特定的行为综合症（即行为特征套件）共同进化。学习风格将按学习准备程度（慢速/快速学习者）、记忆维持（短期/长期）以及使用所学信息的准确性进行分类。我们将使用一种实验进化设置，其中寄生黄蜂将进化出不同的学习风格，以响应我们控制信息的可变性和可靠性水平的不同人工环境。学习风格和适应性之间存在直接联系，因为学习风格将决定黄蜂在特定环境中寻找宿主（蝇蛹）的成功程度。提供宿主的环境的颜色数量以及与特定颜色相关的宿主出现的可靠性会有所不同。我们将监测：(a) 在学习分析中每个环境中新兴的学习方式； (b) 不同学习方式在不同环境中取得的成功； (c) 学习方式和行为综合症是否发生协同进化。这些条件将在实验期间（至少 15 代）受到监控。该设置将提供有关学习风格的成本和收益的信息，并提供有关昆虫学习风格演变的见解。
