Agonistic Behavior of Workers from the subfamilies Nasutitermitinae and Apicotermitinae (Insecta: Isoptera, Termitidae)

The defensive and offensive behavior of Nasutitermitinae and Apicotermitinae workers was analyzed through laboratory bioassays, in order to establish if the aggressiveness is more pronounced in the soldierless species (Apicotermitinae). Ten pairings of five species distributed within the province of...

Termites Agomism Workers Nasutitermitinae Apicotermitinae Neotropical species Termitas Agonismo Obreras Nasutitermitinae Apicotermitinae Especies neotropicales The defensive and offensive behavior of Nasutitermitinae and Apicotermitinae workers was analyzed through laboratory bioassays, in order to establish if the aggressiveness is more pronounced in the soldierless species (Apicotermitinae). Ten pairings of five species distributed within the province of Corrientes (Argentina): Nasutitermes aquilinas, N. corniger, N. fulviceps, Anoplotermes cingulatus and Grigiotermes bequaerti, were performed. All the interspecific encounters showed aggressive actions. The comparisons of the mortality of both species within each pairing were significantly different in seven of them (Mann-Whitney U test, α = 0,05). Considering also the values of the Adjusted Aggression Index (AAI), a “dominant" or more aggressive species was determined for those bioassays. The analysis of total mortality among pairings allowed to separate the altematives according to the agonism level (slight, modérate or strong) (Kruskall-Wallis, múltiple comparisons test of Dwass, Steel, Crichtlow and Fligner, α = 0,05). The possible causes are discussed. Worker behavior was similar in both subfamilies and the intensity of aggressive responses for each species showed differences according to the opponent, without greater aggressiveness of Apicotermitinae workers. Se analizó el comportamiento defensivo y ofensivo de obreras de Nasutitermitinae y Apicotermitinae mediante bioensayos realizados en laboratorio, a fin de establecer si la agresividad resulta más pronunciada en las especies carentes de soldados (Apicotermitinae). Se llevaron a cabo diez alternativas de enfrentamientos, con cinco especies distribuidas en la Provincia de Corrientes (Argentina): Nasutitermes aquilinus, N. corniger, N. fulviceps, Anoplotermes cingulatus y Grigiotermes bequaerti. En todos los encuentros interespecíficos fueron observadas acciones agresivas. Las diferencias de mortalidad entre especies de cada alternativa resultaron significativas en siete de los enfrentamientos (Test U de Mann-Whitney, α = 0,05), en los cuales se estableció una especie más agresiva o “dominante”, considerando además los valores del Indice de Agresión Ajustado (IAA). El análisis de la mortalidad total por bioensayo permitió separar las alternativas según el grado de agonismo desarrollado: leve, moderado o fuerte (Kruskall- Wallis, test de comparaciones múltiples de Dwass, Steel, Crichtlow y Fligner, α = 0,05); se discuten sus posibles causas. El comportamiento de las obreras resultó semejante para ambas subfamilias y la intensidad de las respuestas agresivas varió para las distintas especies de acuerdo a su oponente, sin que se registre agresividad más acentuada en las obreras de Apicotermitinae.
