An n e x e sAbstractThe social behavior of five species of Zetoborinae cockroaches is compared with respectto inter-individual interactions of nymphs in the laboratory. These species belong to thesame Neotropical subfamily and were characterized as gregarious (Lanxoblatta emarginata,Parasphaeria boleiriana, Phortioeca nimbata, Schultesia lampyridiformis) and solitary(Thanatophyllum akinetum) according to field studies. Our results show that gregariousspecies accept closer contacts than the solitary one. The solitary species did not displayespecially short, infrequent or less diverse behavioral sequences when it was forced toremain aggregated, but its interactions are characterized by fewer acts promoting contactand more dominance-like acts. The solitary species is able to symmetrically interact withconspecifics and does not show specific dispersal-promoting behaviors. This suggests thatthe solitary behavior observed in the field for species of Zetoborinae mainly results from apassive spacing tendency and a lack of attraction for conspecifics. One of the gregariousspecies, Parasphaeria boleiriana, was previously known for subsocial behavior with nymphsremaining with the female in a wood chamber after brood birth. This species does not show apeculiar behavioral repertoire but its interactions are characterized by more dominance-likebehavioral acts than the non-subsocial gregarious species.KEY WORDS: social behavior, solitariness, subsociality, interactions, cockroaches,Zetoborinae.315
