Only two sizes of transparent and flexible PVC-tube, PVC-stoppers and a piece of copper gauze are needed to make the system. The insects are aspirated into the tubes. RESUME Un syst~me pratique pour transporter et exp6dier des colonies de fourmis vivantes On d~crit un syst~me ~conomique, l~ger et stable pour h~berger temporairement et pour exp6dier des colonies de fourmis vivantes, ou d'autres petits insectes (fig. 1). Seulement deux types de tubes transparents et flexibles de PVC, des bouchons de PVC et un morceau de gaze d,e cuivre sont n6cessaires pour faire le syst~me. Les insectes sont aspir6s dans les tubes.
