Just as cuckoos dupe other birds into raising their young, so slave-makers trick
worker ants of other species into looking after the slave-makers' brood. All slave-
making species share a set of traits that together constitute what we call the slave
-maker syndrome. To begin with, they all start their colonies by so-called
nonindependent or parasitic colony foundation. In most ants, young queens start
a colony by going off on their own and raising their first workers alone. Slave-
maker queens ...

In the early 1970s at Harvard, Wilson performed lab experiments to try to
determine what would happen if these "obligate slavemakers" had their slaves
artificially removed. Working with a tiny slavemaker called Leptothorax duloti- cus
, which enslaves the tiny Leptothorax curvispinosus, Wilson first noted that the
slavemakers depended on the slaves for food, which was gathered and
regurgitated by their slaves. Similarly, just as in the amazon ants, the tiny
slavemakers left all the brood ...

applied their own sex ratio preferences to the slave-maker brood. Then they
would automatically exhibit a sex ratio close to the slave-maker queen's 1:1
preference, since polygyny makes sex ratios more even (Section 4.7). Trivers and
Hare (1976) suggested that, in their early evolution, slave-maker queens would
manipulate the slave workers to achieve her favored ratio. But the above
argument shows that this manipulation might be minimal. Nonetheless, evidence
exists that the ...

Queens of the slave-maker species Harpagoxenus sublaevis, like L. kutteri
queens, have hypertrophied Dufour's glands that produce propaganda
substances which also cause L. acervorum host workers to attack one another (
Allies et al., 1986). However, in this case the H. sublaevis queen is not accepted
by the workers of the host colony she enters. Instead, she deploys her
propaganda substance not as a diversion but in an overt attack which enables
her to demolish or drive off ...

Kaib et al. (1993) have conducted similar studies with the slave-maker
Harpagoxenus sublaevis and two of its hosts, Leptothorax acervorum and L.
muscorum, and found essentially the same results as Yamoaka (1990). They
found that L. acervorum had 11% n-alkanes, 39% branched hydrocarbons, and
59% alkenes; L. muscorum, in contrast, had 28% n-alkanes, 72% branched
alkanes, and only traces of alkenes. They further found that colonies of either

Trivers and Hare (1976) therefore proposed that the slave-maker queen should
control sex allocation because any mechanisms adopted by her to achieve her
optimal sex ratio would be met with indifference by the unrelated slaves and,
contrary to the case in non-parasitic ants, could not be practically opposed by her
workers. The resulting prediction of unbiased (1:1) population sex investment
ratios is met in two well-studied species (Epimyrma ravouxi and Harpagoxenus
sublaevis: ...

Consequently, more host workers and host queens were killed during raids, and
the raiders captured more brood. However, adaptations and defence have not
stopped there. Ants are well known for colonies sharing a common chemical
signature, with individuals that differ from this being rapidly rejected or killed.
Some slavemaker ants have chemical profiles that resemble their slaves (Kaib et
al. 1993), and in general it should be beneficial for an invading queen when
starting a new ...
