“…3: character 9) and BD1 performed from worker to queen (Fig. 5: characters 27–29) in Metapolybia and Polybia , may be related to queen selection because, in these species, the testing behaviours of workers to queens are constantly present throughout the colony life cycle, and not only during queen selection phase (West‐Eberhard, 1978; Chavarría‐Pizarro, 2013). Also, because workers favour those females that tend to respond with dominance when presented with behaviours such as “Worker dance” (West‐Eberhard, 1978), the response of the potential queens is important to ensure their retention in the colony.…”

All Epiponini wasps are polygynic, with multiple queens alternating over the colony cycle. There are several potential queens in the early stages of this cycle, but as it progresses, the number of queens is reduced. Because most individuals remain reproductively totipotent, there is great potential for conflicts over reproduction. Workers could have an advantage in controlling queen production because they are much more numerous than queens. Nevertheless, the queen selection process is little known for Epiponini. For this reason, we aimed to study the behaviour of queens and workers during queen selection in multiple species of Epiponini, integrate information from previous behavioural studies, and perform a comparative analysis to interpret changes evolutionarily. We conducted observations on nine species belonging to five genera: Brachygastra, Chartergellus, Metapolybia, Polybia and Protopolybia. Females were individually marked to make direct and video observations. Queen production was artificially induced. A total of 28 behaviours related to queen selection were identified. The most aggressive interactions between castes, such as bite and dart, were lost in the major lineages of Epiponini. Bending display I is an ancient behaviour used as the main dominance display. Behaviours exhibited by workers to test queen status arose in the common ancestor of the Epiponini and are not shared by other polistine wasps. Consequently, the act of workers testing queen status probably was present in the Epiponini ancestor. Ritualized test display and dominance behaviours are used in Epiponini as honest signals of the queen's reproductive potential instead of aggressive behaviours. Caste flexibility had already been suggested as the ground plan for Epiponini and is herein discussed as decisive for colony survival of swarm wasps, because it allows colonies to respond efficiently to different situations that may eventually arise.

“…3 and 4). According to Chavarría‐Pizarro (2013), caste interactions occur predominantly during the establishment phase (selection) and elimination, with queens being selected using aggressive behaviours “Dart” or “Bite” (Fig. 3: characters 8 and 10, respectively).…”

Neotropical Swarm-Founding Wasps (Vespidae: Polistinae: Epiponini) Accept Expelled Queens in Case of Queen Loss

2018

In the Epiponini, queen number declines through colony cycle, becausesome queens are expelled from colonies. Here we demonstratethat Epiponini wasps may accept expelled queens in situations ofqueenlessness. One colony of Protopolybia exigua was observed at theUniversity of São Paulo in Brazil; and another of Metapolybia docilis wasobserved at La Selva Biological Station in Costa Rica. Queen removaltests were performed to study workers’ acceptance of expelled queensand queens from other colonies. In P. exigua, the experimental queenelimination caused a change in the workers’ behavior, ranging fromaggressive expulsion of non-selected queens to re-acceptance. In M.docilis workers were willing to accept queens from other colonies afterqueen elimination. Our results indicate that because of a decrease inworkers aggressiveness during the colony cycle, workers may acceptexpelled queens (even foreign ones, in experimental situations) in orderto ensure colony survival.
