Nest architecture of group-living wasps Microstigmus (Hymenoptera: Sphecidae): role of the pedicel as a defense against ants
The nest pedicel of a social sphecid wasp Microstigmus nr. thripoctenus plays an important role in protecting the brood against ant predators, as inferred from data on artificial nests. A pair of artificial nests with or without pedicels was suspended from the undersides of leaves (Carludovica palma...

| description | The nest pedicel of a social sphecid wasp Microstigmus nr. thripoctenus plays an important role in protecting the brood against ant predators, as inferred from data on artificial nests. A pair of artificial nests with or without pedicels was suspended from the undersides of leaves (Carludovica palmata) for 30 min to assess rates of discovery and removal of food (tuna bait) by ants (N = 36 pairs). Three-hundred and forty-three individuals of five ant species removed food at a higher frequency from nests without pedicels (83.3% of 36 nests) than for nests with pedicels (11.1% of 36 nests).<br>La suspensión pedicelar en la arquitectura del nido de la avispa social Microstigmus nr. thripoctenus juega un importante papel en la protección de las crías contra los depredadores, especialmente hormigas, basado de estudios con nidos artificiales. Debajo de las hojas de Carludovica palmata un nido artificial con pedicelo y otro sin pedicelo fueron suspendidos por 30 min para determinar la frecuencia de descubrimiento y eliminación de un cebo (atún) (N = 36 pares). El porcentaje de depredación fue menor (11.1%) en los nidos con pedicelo que en nidos sin pedicelo (83.3%). Se observaron 343 individuos de cinco especies de hormigas atacando los nidos artificiales. |
