Numéro d’image : 11830758
| Rene Reaumur. Engraving of Rene Antoine Ferchault de Reaumur (1683-1757),French naturalist and technologist,studying a trail of ants on a tree. Reaumur described the ants' behaviour in the six volumes of his Memoires pour servir a l'histoire des insects (1734-42). This was the first,comprehensive,scientific work on insects. Reamur also worked on animal digestion,proving that it was a chemical process rather than a mechanical one. In 1750 he designed the first egg incubator. It is now known that ant trails are formed because ants follow a path of odorous pheromone chemicals produced by the leading ant. An ant's antennae will respond to as few as 6 pheromone molecules | |
