Abstract
Plants attract pollinators by providing food rewards. In turn, they receive visits that facilitate plant reproduction through the transfer of pollen by the pollinators. Since pollinators such as bees can use pollen and nectar either for themselves or to feed the brood, this relationship between plants and pollinators usually benefits both parties. However, there are cases where the interests of pollinators and plants do not align, leading to cheating on both sides. The proposed project studies an important aspect of this question by investigating the behavioral response of stingless bee foragers to food sources containing natural quantities of caffeine, an active secondary compound whose main function is to reduce leaf damage by herbivores. The presence of caffeine could even lead to detrimental effects on colonies as it might cause foragers to focus their foraging effort on low quality nectar sources containing caffeine (AU)
