...., 2004 ; Raguso, 2004 ; Thom et al., 2004 ). Insects such as social insects (ants, bees and termites) monitor CO 2 in their hives and control its concentration ( Stange and Stowe, 1999 ; Weidenmüller et al., 2002 ). Some specialized ORs are dedicated to sensing toxic odors. For instance, Or56a...

...Dihego Oliveira Azevedo; Sérgio Oliveira de Paula; José Cola Zanuncio; Luis Carlos Martinez; José Eduardo Serrão ABSTRACT In the ant Ectatomma tuberculatum (Olivier 1792), workers have active ovaries and lay trophic eggs that are eaten by the queen and larvae. Vitellogenins are the main proteins...

...Paul Graham; Michael Mangan ABSTRACT Visual navigation is a critical behaviour for many animals, and it has been particularly well studied in ants. Decades of ant navigation research have uncovered many ways in which efficient navigation can be implemented in small brains. For example, ants show us...

When the two directional cues are in conflict, ants choose a compromise direction. However, landmark guidance appears to be the primary mechanism of navigation used by forager...
