Host Specificity in Raiding Behavior of the Slave-Making Ant Polyergus Lucidus

| Summary: | In the pine barrens of Suffolk County, New York, at least three
species of Formica (subgenus Neoformica) are used as slaves by the
obligatory slave-making ant Polyergus lucidus. In any single nest,
however, only one slave species may be found. This contrasts with
the sympatric, facultative slave-making ants of the genus Formica
(subgenus Raptiformica) in which single colonies often contain two
or more species of slaves. The slave species exclusivity of P. lucidus
might result in two ways: (1) raids could be made to only one slave
species of the four available; or (2) raids could be made to more than
one slave species, but the captured pupae could be consumed differentially
by the resident slaves, favoring the survival to eclosion of
only one slave species. This paper reports the results of a study
demonstrating that colonies of P. lucidus will, if given a choice, raid
only colonies of the slave species already present in the mixed nest.
Since scouts typically lead nestmates to target Formica nests (Cool-
Kwait & Topoff, 1984), this selective process must occur through
the perceptions and actions of the scouts. |
