However, these ants also attend plant‐feeding homopterans to harvest their honeydew secretions, thereby increasing their numbers. This problem can be solved by offering ants alternative sugar sources that are more attractive than honeydew. From natural interactions, it is known that some species manipulate mutualistic partners toward loyalty by adding alkaloids to the food they offer their mutualists. Inspired by this, the addition of alkaloids might be used to make ants loyal to artificial sugar feeders and thus used to reduce populations of ant‐farmed homopterans in ant‐mediated biological control. We aimed to explore whether wood ants (Formica polyctena) would develop a taste preference for morphine‐containing sugar solutions in two‐choice laboratory tests.RESULTSAfter having fed on a morphine/sugar solution for 1 week, ants showed a significant preference for morphine solutions compared with equal concentration sugar solutions without morphine. Furthermore, ants lost this preference after 6–9 days on a morphine‐free diet.CONCLUSIONThe results show that wood ants react to morphine in their food, enabling chemical manipulation of their behavior, most likely through a taste preference. Thus, ants are susceptible to manipulation by mutualistic partners in natural interactions and furthermore may be manipulated artificially in biocontrol programs to avoid ant‐mediated build‐up of homopteran populations. © 2024 The Authors.
