The optimisation and use of biocides is linked to the improvement in our understanding of the target organism. With this in mind we have studied 2 populations of the termite Reticulitermes santonensis De Feytaud. The first inhabiting an urban territory, the trees lining Ave. Boutroux in Paris. The colony has been estimated at 1,200,000 +/- 130,000 insects by triple mark-recapture procedure, foraging a surface of 1080 m2. The area containing visible damages in the trees is of 2,100 m2. The greatest distance covered by an individual is 65 m in 18 days. The second is a field population at Fondette near Tours. The zone studied is of 2,500 m2, the colony being estimated at 230,000 +/- 14,000 insects, foraging a surface of 145 m2. The greatest distance covered by an individual is 40 m in 13 days. This study shows that a termite worker can cover a considerable distance in a short time and that the colonies themselves seem to move within a zone that they cannot totally exploit permanently.
