Colony-specific territorial pheromone in the African weaver ant Oecophylla longinoda (Latreille).
Major workers of Oecophylla longinoda mark their territories with persistent pheromones that are distinguishable to the ants at the colony level. Workers detecting the deposits of an alien colony respond with increased amounts of aversive and aggressive behavior, and they later recruit nestmates to the area at a higher rate. Colonies entering a field impregnated with their own scent also gain a...
متن کاملFactors influencing the responses to nest damage in the African weaver ant. Oecophylla longinoda (Latreille).
Responses of the African weaver ants (Oecophylla longinoda) to nest damages were studied in the field in Nigeria. During the wet season, the ants responded to nest damages almost unexceptionnally by a quick onset of nest-repairing behaviour. The latencies to the start of nest-repairing activities (LN) did not depend on the size of the damage, but they were significantly shorter during the night...
متن کاملAn Overlooked Mandibular-Rubbing Behavior Used during Recruitment by the African Weaver Ant, Oecophylla longinoda
In Oecophylla, an ant genus comprising two territorially dominant arboreal species, workers are known to (1) use anal spots to mark their territories, (2) drag their gaster along the substrate to deposit short-range recruitment trails, and (3) drag the extruded rectal gland along the substrate to deposit the trails used in long-range recruitment. Here we study an overlooked but important markin...
متن کاملEffects of an African weaver ant, Oecophylla longinoda, in controlling mango fruit flies (Diptera: Tephritidae) in Benin.
Six mango, Mangifera indica L., plantations around Parakou, northern Benin, were sampled at 2-wk intervals for fruit fly damage from early April to late May in 2005. Mean damage ranged from 1 to 24% with a weaver ant, Oecophylla longinoda (Latreille), being either abundant or absent. The fruit fly complex is made up of Ceratitis spp. and Bactrocera invadens Drew et al., a new invasive species i...
متن کاملAntagonistic Interactions between the African Weaver Ant Oecophylla longinoda and the Parasitoid Anagyrus pseudococci Potentially Limits Suppression of the Invasive Mealybug Rastrococcus iceryoides
The ant Oecophylla longinoda Latreille forms a trophobiotic relationship with the invasive mealybug Rastrococus iceryoides Green and promotes the latter's infestations to unacceptable levels in the presence of their natural enemies. In this regard, the antagonistic interactions between the ant and the parasitoid Anagyrus pseudococci Girault were assessed under laboratory conditions. The percent...
