Competing beetles attract egg laying in a hawkmoth

Popis výsledku v původním jazyce

In nature, plant-insect interactions occur in complex settings involving multiple trophic levels, often with multiple species at each level.(1) Herbivore attack of a host plant typically dramatically alters the plant s odor emission in terms of concentration and composition.(2,3) Therefore, a well-adapted herbivore should be able to predict whether a plant is still suitable as a host by judging these changes in the emitted bouquet Although studies have demonstrated that oviposition preferences of successive insects were affected by previous infestations,(4,5) the underlying molecular and olfactory mechanisms remain unknown. Here, we report that tobacco hawkmoths (Manduca sexta) preferentially oviposit on Jimson weed (Datura wrightii) that is already infested by a specialist, the three-lined potato beetle (Lema daturaphila). Interestingly, the moths offspring do not benefit directly, as larvae develop more slowly when feeding together with Lema beetles. However, one of M. sexta s main enemies, the par
