Resumo

Intraspecific behavior of the termite Heterotermes tel/uis (Hagen) (Isoptera, Rhinotermitidae) in laborato .. y conditions.Groups of Helerolerllles lenuis (Hagen, 1858) trom tive intestation points were paired in bioassays to investigate the intercolony aggression.The combinations of arena sizes (Petri dishes of 6.0 and 9.0 cm) and temperatures (25 and 28°C) were assessed for effects on intraspecific agonism.Agonistic behavior was scored positive in arena if more than half of the starting number oftermites was dead and injured arter 17 hours.Afier lhe intraspecific encounters it was possible to delimitate three colonies from the five infestation points.No significant differential survival was seen in two different arena sizes and two different temperatures.These assays indicate that the factors governing the agonistic behavior in H. lelluis are complex and seems to be dependent on environmental conditions and individual characterislics (age, size and caste).
