In the present work, the non‐protein amino acid <jats:styled-content style="fixed-case">DL</jats:styled-content>‐β‐aminobutyric acid (<jats:styled-content style="fixed-case">BABA</jats:styled-content>), known to induce plant resistance against a wide range of abiotic and biotic stresses, has been tested for its protective effect against this pest on apple. We first verified the lack of any contact effect of <jats:styled-content style="fixed-case">BABA</jats:styled-content> on the insect itself. Next we applied <jats:styled-content style="fixed-case">BABA</jats:styled-content> as a soil drench to apple and monitored its effect on the population development of aphids after artificial infestation. We demonstrated that <jats:styled-content style="fixed-case">BABA</jats:styled-content> strongly reduced the population growth and that this compound severely affected various life‐history characteristics of the aphid such as female longevity and fecundity, nymph mortality, and larval development.</jats:p>
