Tuberolachnus salignus, or the giant willow aphid, is a species of aphid, in the genus Tuberolachnus. They are reputed to be the largest aphids, with a body length of up to 5.8mm.[1][2] First described by Johann Friedrich Gmelin in 1790, it feeds on many species of willow (Salix species), and has one known specific parasite, Pauesia salignae.[2]
Tuberolachnus salignus does not require a male for reproduction. Only females have ever been recorded, which suggests that reproduction is parthenogenetic and all offspring produced are genetically identical clones.[3]
Host plants
Tuberolachnus salignus is known to feed primarily on willow and Salix tree species such as the white willow (Salix alba), the common sallow (Salix cinerea')[3] and the Indian willow (Salix tetrasperma).[4] The following host tree species have also been recorded:
