Agresi intraspesifik dan waktu penemuan makanan pada semut invasif Anoplolepis gracilipes di Kebun Raya Bogor

We studied the distribution of the Yellow Crazy Ant (Anoplolepis gracilipes) Smith (Hymenoptera: Formicidae) in Bogor Botanical Garden (BBG). Biological invasions by A. gracilipes can negatively impact other species. Individual nests of this ant can...

The aim of this research was to study aggression between and resource discovery of different <em>A. gracilipes </em>supercolonies in BBG. Intraspecific aggression was calculated as three different aggression indices obtained by performing intercolonial arena encounters. Resource discovery was measured as time until honey baits in known distances to colony entrances were discovered.

The absence of intercolonial aggression between three of five nest clusters suggested that they actually belong to the same supercolony. On average, <em>A. gracilipes</em> needed less than 1 hour to find the food on bait plate in 20 m distance.
