TL;DR: Characteristic features of the species of Macrosiphum Passerini occurring in India are redefined and a key for the determination of thespecies from apterous viviparous females is provided.
Abstract: Characteristic features of the species of Macrosiphum Passerini occurring in India are redefined and a key for the determination of the species from apterous viviparous females is provided. The food plants of the species, their distribution In India, biometry and pigmentation of the parts of the body, previous records, biology and salient features of the 21 species so far recorded in India are given.

TL;DR: The biology and economic status of aphids attacking rice throughout the world is reviewed, as is the literature concerning other aphids found in or near irrigated rice fields but not usually infesting rice, and 37 species of aphid belonging to seventeen genera are considered.
Abstract: The biology and economic status of aphids attacking rice throughout the world is reviewed, as is the literature concerning other aphids found in or near irrigated rice fields but not usually infesting rice. Altogether, 37 species of aphids belonging to seventeen genera are considered. The aphids are dealt with in two similar–sized groups according to their feeding sites, namely root–feeding and leaf–, stem– and ear–feeding species. Aphis craccivora Koch and Myzus persicae (Sulz.) are regarded as ‘occasional rice aphids’ as they are found on rice occasionally but do not regularly infest rice plants. A. gossypu Glov. is treated as a ‘rice aphid’ although its occurrence on rice plants is also sporadic. In addition to the literature survey, additional information is given based on field collections and observations, on the rice aphid component of more than 18 000 aphids trapped in yellow pan traps, on the natural enemies reared and collected and from laboratory experiments in Japan. Unpubished information was also extracted from the data labels of the British Museum (Natural History) aphid collection. The ecological relationships between rice aphids and aphids associated with weeds near irrigated rice fields in the Yamaguchi area of Japan is discussed. Three of the rice aphids were found on 22 species of weeds and the three ‘occasional rice aphids’ also occured on 22 species of weeds. A total of 43 species of weeds harboured aphids.

TL;DR: 43 aphid species distributed over 26 genera under 3 subfamilies under 3 families are reported, including 13 new records for South India, and 8 are endemic to India.
Abstract: RAYCHAUDHURI, D. N., GHOSH, D., RAYCHAUDHURI,. D. and AGARWALA, B. K. 1981. Studies on the aphids (Homoptera: Aphididae) from South India, 1. Ins. matsum. n.S. 23: 1-20. This paper reports 43 aphid species distributed over 26 genera under 3 subfamilies. These aphid species include 13 new records for South India. Out of the reported species 8 are endemic to India.

TL;DR: Morphometric investigations using principal component analysis and canonical discriminant analysis have allowed us to clarify the relationships of several Australian populations within the aphid genus Sitobion and argue against describing these as separate species.
Abstract: The taxonomic status of several Australian populations within the aphid genus Sitobion has been uncertain for many years. Morphometric investigations using principal component analysis and canonical discriminant analysis have allowed us to clarify the relationships of these entities. A form on grasses, referred to in the literature as Sitobion near fragariae, is shown not to separate morphometrically from S. fragariae (Walker) collected in Europe and North America. In contrast, Sitobion miscanthi (Takahashi) Clones 61 (2n = 20) and 34 (2n = 17) separate unequivocally from each other and from Clone 4 (2n = 18), the supposed ancestral karyotype. We argue against describing these as separate species. Sexual forms of S. miscanthi and Australian S. fragariae reared in the laboratory were compared with the sexual forms of European Sitobion avenae (Fabricius) and S. fragariae, respectively. Australian specimens from Smilax glyciphylla and Smilax australis (Smilacaceae) are not Sitobion smilacifoliae (Takahashi).

TL;DR: Among the flowering plants, the family Asteraceae or Compositae is the largest family in the world, but in India, it occupies seventh place, and only 207 species were found to be attacked by 199 aphid species in India.
Abstract: Among the flowering plants, the family Asteraceae or Compositae is the largest family in the world, but in India, it occupies seventh place. Few members of this family provide edible oils, lettuce, chicory, artichokes, yacon, sweetening agents, coffee substitutes, and herbal teas and other beverages. Several species are grown as ornamental plants for their flowers, and some are important ornamental crops for the cut flower industry. Several species of this family possess medicinal properties. Out of about 696 plant species described under the family, only 207 species were found to be attacked by 199 aphid (Insecta : Homoptera : Aphididae) species in India. Among the aphid species, Aphis gossypii Glover was recorded feeding 77 food plants of Asteraceae followed by Brachycaudus helichrysi (Kalt.) (72 species), Aphis spiraecola Patch (70 species), Myzus persicae (Sulzer) (45 species), Myzus ornatus Laing (35 species), Aphis fabae Scopoli (25 species), and Aphis craccivora Koch (23 species). Artemisia and Sonchus were observed to be attacked by 60 and 25 aphid species, respectively.

TL;DR: The genera of Australian aphids are described in detail and a reference to a recent revision of the genus and to a detailed description of each species is given where possible.
Abstract: Keys are given for the determination of the families, subfamilies, genera, and the 119 species of aphids known from Australia. The keys are supplemented by 192 figures. The genera of Australian aphids are described in detail and a reference to a recent revision of the genus and to a detailed description of each species is given where possible. A summary of the known host plant range and geographical distribution of each species is given. A few references to recent economic literature are given for those species regarded as pests.
