\"\"Les termites ne sont pas nocifs partout. En tous cas c’est ce qu’ont r\u00e9v\u00e9l\u00e9 les membres australiens du Common Scientific and Industrial Research Organisation<\/strong> (CSIRO<\/strong>).<\/span> C’est sur un site aurif\u00e8re d’Australie Occidentale, que ces scientifiques ont d\u00e9couvert que les termites \u00e9taient en r\u00e9alit\u00e9 des petits chercheurs d’or<\/a><\/strong>. En effet, ces insectes sociaux qui passent la majorit\u00e9 de leur temps \u00e0 amonceler les d\u00e9chets de ce qu’ils ing\u00e8rent, apportent de pr\u00e9cieux enseignements quant \u00e0 leur environnement. C’est ainsi que les monticules amass\u00e9es par ces insectes b\u00e2tisseurs ont r\u00e9v\u00e9l\u00e9 la pr\u00e9sence de m\u00e9tal pr\u00e9cieux<\/a>. Cela a conduit les scientifiques du CSIRO<\/strong> \u00e0 d\u00e9duire que les colonies de termites \u00e9voluaient dans un milieu aurif\u00e8re. Cette d\u00e9couverte est aussi surprenante qu’utile, d’autant plus qu’une grande partie du paysage australien est couverte d’une couche de mati\u00e8re \u00e9rod\u00e9e. Les termites sont donc d’une aide pr\u00e9cieuse pour la d\u00e9tection de gisements d’or<\/a>.<\/span> Concr\u00e8tement, les chercheurs qui ont mis \u00e0 jour cette propri\u00e9t\u00e9 des termites, ont men\u00e9 des exp\u00e9riences pour \u00e9valuer l’ampleur du ph\u00e9nom\u00e8ne. A l’issue de ces exp\u00e9rimentations, il s’est av\u00e9r\u00e9 que les termites pourraient facilement servir d’auxiliaires aux chercheurs d’or<\/a>.<\/span> D’autre part, l’utilisation des termites pour chercher le m\u00e9tal pr\u00e9cieux<\/a> pr\u00e9sente non seulement des avantages en mati\u00e8re de co\u00fbts mais \u00e9galement en mati\u00e8re de pr\u00e9servation de l’environnement, car cela limiterait les forages. Seul b\u00e9mol, m\u00eame si les insectes r\u00e9ussissent \u00e0 descendre loin en profondeur, ils ne font remonter \u00e0 la surface que ce qu’il y a dans les 4 derniers m\u00e8tres<\/strong> proches de la surface.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
