Division of labor in anti-parasite defense strategies in ant colonies

2014

Division of labor is a key characteristic of social insects and contributes to their ecological success. Especially in disease defense, the intra-colony partitioning of sanitary work can reduce disease transmission, keep nestmates available for other tasks and reduce costs associated with sanitary task performance (i.e. at the behavioral and physiological level). Factors internal and external to the individual affecting sanitary task allocation are not well known and most studies investigated genetic differences between workers performing behavioral sanitary work. In the first two studies I addressed whether individual experience (through repeated exposure to a sanitary hazard or performanc…
