Social insects are known for their behavioural plasticity and learning abilities. In the present work, we evaluated whether a single past experience could influence Vespula germanica (F.) foraging behaviour by analysing wasp response in two changing situations: when food was displaced at different distances from a previously learned location and when the amount of resource was significantly decreased. In the former case, wasps were allowed to collect meat once from a dish which was later displaced 300, 600 or 900 mm from the previous location. Thus, on the second visit, wasps encountered an empty dish in place of the previously baited one. We recorded the time taken to find the displaced food, the number of hovers over the previously learned location and the direction of first approach of returning foragers. Wasps spent less time searching at the previously learnt site when the dish with food was displaced 300 mm rather than 600 or 900 mm from the learned location. In the second experiment, when two dishes with food were simultaneously offered, one containing 20 g and another 80 g, wasps preferred the 80 g dish. On their second visit, we switched the position of the dishes and recorded which dish wasps collected food from. We found that most wasps collected food from the previously learned location and not from the dish with the more abundant resource. This study illustrates the remarkable influence of a single collecting experience on V. germanica subsequent foraging behaviour.

“…Vespids learn visual information during an orientation flight, to find their path to or back from foraging sites (Ugolini, 1987; Raveret Richter & Jeanne, 1991; see Raveret Richter, 2000 for a review). In this orientation flight, the individual flies along ever‐increasing arcs around the nest that allow combining flight trajectory (arcs) and gaze orientation to acquire sufficient visual cues for homing (Stürzl et al., 2016; Toh & Okamura, 2003; Zeil, 1993). One should, however, consider that workers’ previous experience was not controlled in our experimental design so some individuals might have already experienced long trips from their nest that could have facilitated their return.…”

In social insects, the activity rhythm of foragers and their action range determinate the activity of the colony. In vespids, which are mostly predators, the foraging range of workers determines their maximum predation pressure round the nest. One of these species, Vespa velutina, a recently invasive species introduced into Europe, exerts a strong predation on honeybees at the hive. Therefore, the definition of its activity rhythm and spatial range of predation is of primary importance. Using radio frequency identification tags (RFID), two experiments were carried out to (a) determine their return ability (called homing) in releasing 318 individuals at different distance from their colony and (b) monitor their foraging activity rhythm and the duration of their flights based on 71 individuals followed 24 hr/24 during 2 months. The homing ability of V. velutina was evaluated to be up to 5,000 m and was not affected by the cardinal orientation of release point. The lag time to return to the nest increased with the distance of release. Most of the flight activity took place between 07:00 a.m. and 08:00 p.m., hornets doing principally short flights of less than an hour. Foraging range was thus estimated ca. 1,000 m around the nest. This study of V. velutina assisted by RFID tags provides for the first time a baseline for its potential foraging distance that increase our knowledge of this species to (a) refine more accurately models for risk assessment and (b) define security perimeter for early detection of predation on invasion front.

“…The assessment of patch size and quality and the decision to return to a site means that they must learn the relevant characteristics of patches. Previous studies have demonstrated the presence of such cognitive traits in the Vespidae (D'Adamo & Lozada, 2003;Toh & Okamura, 2003;Weiss et al, 2004;Lozada & D'Adamo, 2006;Warkentin et al, 2006;Moreyra et al, 2012) and it has been argued that the plasticity of their cognitive traits could favor invasiveness in new environments (D'Adamo & Lozada, 2007.…”

Spatial distribution of Vespa velutina individuals hunting at domestic honeybee hives: heterogeneity at a local scale

et al. 2014

Since its recent introduction into Europe, the yellow-legged hornet, Vespa velutina, has become a major predator of the domestic honeybee, Apis mellifera, but little is known about its hunting behavior. We studied V. velutina hunting behavior by a capture-mark-recapture procedure in an experimental apiary. A total of 360 hornets were captured and tagged, and we determined: (i) the number of hornets visiting the apiary and the changes in time, (ii) the average number of individual visits per half-day and the time elapsed between consecutive recaptures, and (iii) the individual and global distribution of the hornets in the apiary. More than 50% of the marked hornets were recaptured at least once, this increased to 74% in considering the first marked individuals. We estimated 350 hornets visiting the patch daily with at least 1 visit per half-day. The number of marked hornets decreased over time while the number of unmarked ones increased, suggesting a turnover of individuals. The reduction of the delay between consecutive visits indicates that hornets became more efficient over time. Most of the hornets (88%) were recaptured in front of different hives but, overall, the global distribution was aggregative. Hornets were mainly recaptured in front of 1 hive which was neither the smallest nor the biggest colony, suggesting that the major cue used by hornets is not the amount of food. We hypothesize that the defensive behavior of the honeybee colony could explain our results which may be promising to further studies.
