In French Guiana, the arboreal nests of the swarm-founding social wasp Protopolybia emortualis (Polistinae) are generally found near those of the arboreal dolichoderine ant Dolichoderus bidens. These wasp nests are typically protected by an envelope, which in turn is covered by an additional carton 'shelter' with structure resembling the D. bidens nests. A few wasps constantly guard their nest to keep D. bidens workers from approaching. When alarmed by a strong disturbance, the ants invade the host tree foliage whereas the wasps retreat into their nest. Notably, there is no chemical convergence in the cuticular profiles of the wasps and ants sharing a tree. The aggressiveness of D. bidens likely protects the wasps from army ant raids, but the ants do not benefit from the presence of the wasps; therefore, this relationship corresponds to a kind of commensalism.

Social wasps make up a significant part to the diversity of the Hymenoptera order, one of the most varied insect groups. Beyond their ecological importance, these insects use their venom for defense, protecting their colonies. The venom of social wasps are rich in biologically active substances, including biogenic amines, peptides, proteins, enzymes, allergens, and volatile compounds.

Parasites can influence host physiology and behavior, often impairing cognition. We investigated how infection and parasite load affect olfactory learning and memory in the paper wasp Polistes dominula workers parasitized by the insect parasite Xenos vesparum (Strepsiptera). We adapted a Pavlovian conditioning assay based on the proboscis extension reflex protocol.

To test the hypothesis that the expression profiles, evolutionary patterns, and functionalities of anti-microbial peptides (AMPs) and proteins in some hymenopteran and heteropteran species are influenced by their distinct ecological traits, we conducted venom and salivary gland-specific transcriptome analyses. We compared the expression and evolutionary patterns of anti-microbial peptide and proteins across 22 hymenopteran and 9 heteropteran species. Additionally, we investigated the structural properties of selected defensins and assessed their anti-microbial and hemolytic activities.

Eusociality in insects has arisen multiple times independently in Hymenoptera (bees, wasps and ants), Blattodea (termites) and Coleoptera (beetles). In Hymenoptera and Blattodea, the evolution of eusociality led to species proliferation. In the hyperdiverse Coleoptera, obligate eusociality evolved only once, in the ancient Australian ambrosia beetle Austroplatypus incompertus (Curculionidae: Platypodinae).

Social isolation often has lasting negative effects on social behavior, but less research has tested how the timing of isolation influences its effects. Some behaviors have a sensitive period where experience has particularly strong effects, while other behaviors are more flexible. Here, we test how the timing of social experience influences the development of individual face learning in wasps.
