The cooperative defence in ant societies is a suitable system that can keep the integrity of the colonies from threats represented by competitors, predators and parasites. This is due to the presence of a well‐organized alarm communication system t

The alarm behaviour of the ant Formica rufibarbis was investigated by laboratory bioassays in which different exocrine glandular secretions were tested. This was done in order to identify glandular sources of the alarm pheromones involved. Experiment

> ‘Female‐calling syndrome’ is the reproductive strategy adopted by the European slave‐making ant Polyergus rufescens, where a winged female disperses a short distance from the nest, ascends to an elevated position (at the top of a blade of g

A review of field and laboratory research concerning raiding behaviour, mating strategies and colony founding in Formica sanguinea and Polyergus rufescens (respectively facultative and obligatory parasites of the Serviformica species) is presented. T

In this research, the necessary conditions to induce raiding activity of the slave‐making ant Polyergus rufescens were re‐created in the laboratory. This, the first description of such behaviour observed under controlled situations, facilitates t

The role of decyl butyrate (the main component of the secretion of Dufour’s gland in newly-mated queens) during host-colony usurpation was investigated in the European amazon ant Polyergus rufescens. The effect of this ester on the behaviour of wor

Dufour’s gland contents of the queens of the slave-making ant species Polyergus rufescens and its host, Formica cunicularia, were analysed by gas chromatography-mass spectrometry. In P. rufescens, the gland contains a mixture of several esters, one

In the European slave-making ant Polyergus rufescens, the occurrence of chemical strategies during the initial phase of dependent colony foundation or usurpation was investigated. To test this idea, we analysed the effect of the secretion of differen

We investigated the factors involved in the orientation of raiders of the European Amazon ant, Polyergus rufescensand how these factors are used by raiders during the different phases of slave-making expeditions. Ants at the head of the raiding colum
