Like many other animals, insects are capable of returning to previously visited locations using path integration, which is a memory travelled direction and distance. Recent studies suggest that Drosophila can also use integration return food reward. However, the existing experimental evidence for in has potential confound: pheromones deposited at site reward might enable flies find rewarding even without memory. Here, we show indeed cause naïve accumulate where previous had been rewarded navigation task. Therefore, designed an experiment determine if despite pheromonal cues by displacing shortly after optogenetic We found returned location predicted memory-based model. Several analyses consistent with as mechanism conclude although often important fly must be carefully controlled future experiments, may performing integration.

Path integration is a key navigation mechanism used by many animals, involving the of direction and distance path segments to form goal vector that allows an animal return directly its starting point. While well established for animals walking on solid ground, evidence in moving without ground contact, such as flying insects, less clear. The review focuses Hymenoptera, particularly bees, which are extensively studied. Although bees can use flight information, genuine limited. Accurately assessing travelled major challenge because it relies optic flow-the movement visual patterns across eye caused locomotion. Optic flow depends both animal's speed spatial layout environment, making ambiguous precise measurement. crucial like desert ants navigating sparse environments with few navigational cues, we argue Hymenopterans visually complex environments, rich objects textures, rely additional cues rather than integration. As they become more familiar may iteratively refine unreliable estimates derived from flow. By combining this refined information directional could determine improve their ability navigate efficiently between locations. In case honeybees, also enables them communicate these vectors other through waggle dance.

The insect central complex appears to encode and process spatial information through vector manipulation. Here, we draw on recent insights into circuit structure fuse previous models of sensory-guided navigation, path integration memory. Specifically, propose that the allocentric encoding location provided by creates a spatially stable anchor for converging sensory signals is relevant in multiple behavioural contexts. reference frame given transforms goal direction demonstrate modelling it can enhance approach target noisy, cluttered environments or with temporally sparse stimuli. We further show same improve performance more navigational task route following. model suggests specific functional roles elements helps explain their high preservation across species.

Foraging behavior is essential for the survival of organisms as it enables them to locate and acquire food resources. In Drosophila, hunger triggers a distinct search following consumption small quantities sugar solution.

After finding food, a foraging animal must decide whether to continue feeding, or explore the environment for potentially better options. One strategy negotiate this tradeoff is perform local searches around food but repeatedly return feed. We studied behavior in flies and used genetic tools uncover underlying mechanisms. Over time, gradually expand their search, shifting from primarily exploiting sources exploring environment, change that likely driven by increases satiety. found flies’ search patterns preserve these dynamics even as overall scale of modulated starvation-induced changes metabolic state.
