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 ...

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 ...

shows that while the adults have very different chemical profiles, the pupae are
often quite similar and therefore seem to acquire the odour of their colony as they
mature.24 This explains how it's possible to integrate broods from different
species and colonies into the same nest. Some slavemaker species apparently
steal broods from several species in order that each undertakes different tasks in
the nest, just like a division of labour that often occurs in ant colonies with
different castes.

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: ...
