Summary 1. Winged morph production in aphids is a phenotypic trait that has traditionally been seen as response to unfavourable environmental conditions. The evidence support this theory reviewed and the ecological evolutionary significance of findings discussed. 2. common assertion poor host‐plant nutritional quality leading increased winged morphs does not always apply, particularly when exceptionally poor. available data are skewed heavily towards Myzus persicae , for species dynamical change plant appears be important with respect wing induction. 3. Crowding may less influential stimulus induction study methods approach natural conditions experienced by on their host plant. 4. growing interactions other organisms can induce aphid colonies reviewed. In case enemies, such an colony regarded induced defence. Wing also act means transmission virus or fungal pathogen.
