Florida Entomologist 97 (1), 162-167
Abstract: First occurrence of the invasive aphid species, Wahlgreniella nervata (Gillette) (Hemiptera: Aphididae) is reported from material collected in Bengaluru, India. Apterous and alate viviparous females were found feeding on tender shoots, young leaves and flower buds of rose (Rosaceae). The identity of this aphid species is supported by morphometrics (aptera and alata) corroborated with molecular analysis based on a fragment of the mitochondrial DNA containing the 5' region of the cytochrome c oxidase 1 (mtCOI). Diagnostic characters to differentiate W. nervata from other major aphid species viz., Macrosiphum rosae (Linnaeus) and Sitobion rosaeiformis (Das), on Rosa spp., its host plants, distribution and natural enemies are provided. This is a new distributional record of W. nervata. The invasive species compendium developed by CAB International, 2013 has listed W. nervata as invasive in nature.
