The articles provides updated checklist of Indian aphids (Aphididae: Hemiptera) belonging to the subfamily Eriosomatinae and their food plants. Out of valid species of world Eriosomatinae. In preparing of this checklist, recent world literatures (published up to January, ) were scrutinised for synonymy of the aphid species as well as their host plants available at websites: http. * More aphid species in the keys * Approximately new references It features those aspects of the biology of aphids most relevant to their taxonomy and identification, followed by a crop-oriented illustrated identification guide. It also includes a comprehensive, systematic account of the genera and species of aphids inhabiting crop plants. Provides a comprehensive species-by-species account of all the world's tree-dwelling aphids ( species). An introductory section gives notes on aphid life cycles, polymorphism and the.
In this contribution, food plants of only 33 genera and species of aphids belonging to the tribe Macrosiphini (Nasonovia to Xenosiphonaphis) are catalogued. These aphids feed on plant. Evolution. Aphids originated in the late Cretaceous about (Mya), but the Aphidinae which comprises about half of the described species and genera of aphids alive today come from their most recent radiation which occurred in the late Tertiary less than 10 Mya.. Characteristics. Members of the Aphididae are soft-bodied, pear-shaped insects called aphids, as are other members of the. Aphids belonging to Insecta class, Hemiptera order, Aphididae family, encompass about species in the world (Remaudière and Remaudière, ; Blackman and Eastop, ). Their ecology. Keywords: Aiceoninae, Anoeciinae, Chaitophorinae, Drepanosiphinae, food plant, aphids. _____ Introduction Aphids are a group of over 4, species of small homopteran phytophagous insects that suck the phloem fluid of plants. They are popularly known as plant-lice or ant-cows and vary in size between to mm in length. Many species of.
potential with some of aphids species (Aphididae) having more than ten generations in one year (Iversen and Harding, ). Because of their direct (sucking) and indirect (transmission of viruses and honeydew secretion) damage on cultivated and wild-growing plants, the producers of plant food, ornamental plants and feed for. Polyphagous aphids. Most aphid species are restricted to a single host-plant genus. Many can only raise successful colonies on one plant species. Host alternating species are similarly-restricted regarding their primary host, but much less so regarding possible secondary hosts.A small proportion of species (1 or 2%) can raise successful colonies on many plant genera, and are considered. Fossil history. Aphids, and the closely related adelgids and phylloxerans, probably evolved from a common ancestor some, in the Early Permian period. They probably fed on plants like Cordaitales or their soft bodies, aphids do not fossilize well, and the oldest known fossil is of the species Triassoaphis cubitus from the Triassic. They do however sometimes get stuck in plant. It has a narrow host range being recorded from many species among 6 plant families including, Asteraceae and Apiaceae, but has been recorded from Cornus (Cornaceae) and Epilobium (Onagraceae) and others. Economic importance. It is particularly important on wild carrot, celery, parsnip, and various species of composites.
