Аннотация:Miniaturization presents insects with the task of preserving vital body functions at a signifi cantly reduced body size. We have studied the eff ects of miniaturization on the functioning of the insect nervous system by the example of the parasitoid wasp Trichogramma telengai. Despite a smaller number and a lower volume of neurons, T. telengai demonstrated the ability for associative learning and memory retention for up to 6 h after training. The training and testing were performed using a setup based on the Morris water maze design and suitable for comparative assessment of associative learning abilities in small animals of diff erent taxa. Our data expand the understanding of the miniaturization eff ects on the cognitive abilities of animals and may help to determine which structural factors limit the minimum size of the functional insect brain.
