Long-term memory in <i>Thrips tabaci</i> (Thysanoptera, Thripidae)

Microinsects are capable of associative learning and memory retention despite significant reduction in the number and size of neurons. Previously, the capabilities of Thrips tabaci (Thysanoptera, Thripidae) for associative learning and the formation of short-term memory have been demonstrated. In this study, an additional training session was added, as well as a time interval between them. Increasing the number of training sessions and spacing these out over time allowed us to demonstrate the persistence of memory traces for up to 24 hours. Thus, for the first time, the presence of consolidated forms of memory in the order Thysanoptera has been revealed.
