Experiments made on ants as biological models revealed that a saccharose/sucralose 95.5/.05 mixture increased sugar water consumption, decreased general activity, precision of reaction, audacity, brood caring, cognition and ability in acquiring visual conditioning (short term memory), induced aggressiveness against nestmates, and slightly reduced tactile perception. It may not change the speed of locomotion and did not affect middle and long term memory. The adverse effects may be related to the strong sugared taste of the mixture (in presence of sugar and the saccharose/sucralose mixture, the ants slightly preferred the mixture) though it contains little sugar, and to the toxic chloropropanols sucralose may produce. When ants consumed again sugar instead of a saccharose/sucralose mixture, their aggressiveness rapidly decreased during eight hours and entirely vanished in 29 hours.Keywords

Using ants as models, the glycoside rebaudioside A used as a sweetener extracted from the plant Stevia rebaudiana was shown to have no effect on the individuals’ food consumption, locomotion, precision of reaction, response to pheromones, brood caring, cognition, as well as visual and olfactory conditioning and memory. This sweetener (the commercial product ‘stevia’) slightly increased the ants’ audacity, and when having the choice between it and saccharose, the ants somewhat preferred the later. In fact, the ants were not inclined to consume stevia and somewhat looked everywhere for their usual preferred sugar. We conclude that stevia is a safe sweetener which does not impact general health, behavior and cognition, although it is generally perceived less pleasant than saccharose.Keywords

Statins are nowadays largely used for caring of persons suffering from hypercholesterolemia. Their use was recently debated. We studied the effects of simvastatin on ants as models. We observed that this product enlarged the insects’ sugar food consumption, reduced their general activity, linear speed, orientation ability, trail following, audacity, tactile and pain perception, cognition, ability in escaping from an enclosure, visual and olfactory conditioning ability (thus their shortterm memory), and their middle term visual and olfactory memory. Simvastatin did not affect the ants’ relationship with their nestmates. The ants developed adaptation to some adverse effects of simvastatine, and presented no habituation to beneficial effects. Also, simvastatine did not lead to dependence. Consequently, even if simvastatin is efficient in reducing the amount of cholesterol, and leads to some adaptation, no habituation and no addiction, it has several harmful effects. This drug should thus be used only in case of high necessity, never for children, and natural alternative with very few adverse effects should be advantageously researched.
