SUMMARY
A cheap, light and stable system for temporary housing and mailing live ant
colonies, or other small insects, is described (fig. 1). 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.
