Aphids (Hemiptera: Aphididae) and their host plants in Ayodhya district, Uttar Pradesh, India
Abstract : The paper deals with the association of aphids with their food plants in the district Ayodhya, Uttar Pradesh. Results demonstrate that a total of 52 species of aphids belonging to 26 genera under 5 subfamilies are recorded in 220 villages distributed in all five sub-districts (tehsil) of the district Ayodhya. Most of the species belong to the subfamily Aphidinae (44 species) followed by Greenideinae (4 species), and Calaphidinae and Eriosomatinae (each 1 species). A total of 159 species of plants belonging to 43 families are associated with these aphids. The plants belonging to the family Poaceae suffer heavily with aphid attacks followed by the plants belonging to the families Fabaceae, Solanaceae, Brassicaceae, Cucurbitaceae and Malvaceae. A total of 22 species are monophagous, 24 species are oligophagous and 6 species are polyphagous. A highly polyphagous aphid species is Aphis (Aphis) gossypii Glover infesting 75 plant species belonging to 31 families followed by Myzus (Nectarosiphon) persicae (Sulzer) (34 plant species belonging to 14 families), Aphis (Aphis) craccivora Koch (34 plant species belonging to 10 families), Aphis (Aphis) spiraecola Patch (23 plant species belonging to 12 families), Aphis (Aphis) nasturtii Kaltenbach (11 plant species belonging to 6 families), and Aphis (Aphis) solanella Theobald (10 plant species belonging to 6 families). Mustard, pea, pulses, vegetables, maize, sorghum etc. are infested with several aphid species and need their control measure.
