The predatory behavior of Pheidole megacephala.
We studied the foraging and predatory behaviors of the invasive African myrmicine ant, Pheidole megacephala (F.) in its native range. Workers can singly capture a wide range of insects, including relatively large prey items. For still larger prey, they recruit at short range those nestmates situated within reach of an alarm pheromone and together spread-eagle the insect. These behaviors are com...
متن کاملQueen Replacement in Dequeened Colonies of the Argentine Ant Iridomyrmex Humilis
Replacement of killed or damaged queen by a new inseminated queen produced in the same nest is regularly accomplished in honey bees (Butler, 1967; Wilson, 1971; Michener, 1974). In the lower termites, e.g., Calotermes, it has been known for a long time that the removal of the sexual pair leads to the differentiation of neotenic reproductives from larval, pseudergate or nymphal forms (Grass6 and...
متن کاملIsolation and characterization of microsatellite loci from the invasive ant Pheidole megacephala.
We report the characterization of eight microsatellite markers in the big-headed ant Pheidole megacephala, a pest ant registered in the list of '100 of the world's worst invasive alien species'. An enrichment protocol was used to isolate microsatellite loci, and polymorphism was explored with 36 individuals collected in an invasive population from Australia and 20 individuals collected in a pop...
متن کاملA revision of Pheidole Westwood (Hymenoptera: Formicidae) in the islands of the southwest Indian Ocean and designation of a neotype for the invasive Pheidole megacephala.
The myrmicine genus Pheidole Westwood is revised for the smaller islands of the Southwest Indian Ocean: Comoros, Juan de Nova Island, Mauritius, Mayotte, Reunion, and the Seychelles. Descriptions and keys are provided for the thirteen species on these islands of which seven are newly described: P. decepticon sp. n., P. dodo sp. n., P. komori sp. n, P. loki sp. n., P. megatron sp. n., P. ragnax ...
متن کاملOrigin of the Bermuda volcanoes and Bermuda Rise: History, Observations, Models, and Puzzles
Deep-sea drilling on DSDP Leg 43 and on Bermuda itself, together with geophysical data (anomalies in basement depth, geoid and heat flow) and modeling have long suggested the uplift forming the Bermuda Rise, as well as the initial igneous activity that produced the Bermuda volcanoes, began ca. 47-40 Ma, during the early to middle part of the Midde Eocene. Some authors attribute 65 Ma igneous ac...
