TL;DR: Recent surveys in the pest-affected areas of Maharashtra and Karnataka have yielded several indigenous predators which include coccinellids, neuropterans, syrphids and a pyralid.
Abstract: Sugarcane woolly aphid, Ceratovacuna lanigera Zehntner has been recently reported in outbreak proportions from western and southern India. Though the pest was first reported from West Bengal in 1958 and later from other parts of Northeast India, it had not made its way to other parts of India. The pest breeds on plants of the family Poaceae, but has been also observed on members of Bixaceae, Theaceae and Combretaceae. It has been recorded on ten species of plants in India. It reproduces parthenogenetically and has an anholocyclic (absence of sexually producing generation) life cycle. Thirty-eight natural enemies have been recorded on the aphid from different parts of the world. Recent surveys in the pest-affected areas of Maharashtra (western India) and Karnataka (southern India) have yielded several indigenous predators which include coccinellids, neuropterans, syrphids and a pyralid. Integrated pest management involving mainly mechanical and biological control appears to be the best option. There is ample scope for more directed work on this important emerging pest, especially in the areas of pest ecology and distribution. The role of resistant varieties, and biological, cultural and mechanical control in managing the pest needs to be carefully evaluated.

TL;DR: Although there were no new distribution records for natural enemies, four new host associations of coccinellid predators are reported through this study.
Abstract: A survey was conducted to collect aphids, coccids and their natural enemies from Sikkim, India. Forty one species of aphids, five species of mealybugs, four species of soft scales, three species of armoured scales and a species of orthezid were recorded. Out of these, seventeen species of aphids, a species of soft scale and mealybug each, were reported for the first time from Sikkim. Two species of aphids were recorded for the first time from India. Among natural enemies of aphids and coccids, twelve species of coccinellids and two species of braconids, one species each of Aphelinidae and Pteromalidae were recorded during the survey. Although there were no new distribution records for natural enemies, four new host associations of coccinellid predators are reported through this study. The present study resulted in addition of 17 new species of aphids and a new species of mealybug to the existing collection of Aphididae and Pseudococcidae at NBAIR, Bangalore.

Besides, five new records of aphids from India and apterous ovipara of Megoura cajanae are also described. The status of Sitobion indicum Basu 1964 is discussed.

TL;DR: An updated checklist of Indian Aphidini with the valid scientific name of the aphids as well as their food plants is provided.
Abstract: The Aphidini is one of the 2 tribes of the subfamily Aphidinae (Aphididae: Hemiptera) containing about 830 species/subspecies assigned to 33 genera. Out of these, only 9 genera and 70 species/subspecies were recorded from India infesting 940 plant species belonging to 138 families, out of which only 19 families are monocot. Indian Aphidini are recorded mostly on the plant family Asteraceae (102 plant species), followed by Fabaceae (96 plant species), Poaceae (92 plant species), Lamiaceae (46 plant species), Rosaceae (38 plant species), Solanaceae (34 plant species), Apocyanaceae (28 plant species), Rubiaceae (26 plant species), Malvaceae (25 plant species), Rutaceae (22 plant species), Cucurbitaceae (22 plant species), Polygonaceae (21 plant species), etc. Out of 70 described species of Aphidini from India, 14 species are monophagous; 40 species are oligophagous infesting 2 to 20 plant species; and 8 species are moderately polyphagous infesting 21 to 55 plant species while 8 species are highly polyphagous feeding on 55 upto 569 plant species. The present contribution provides updated checklist of Indian Aphidini with the valid scientific name of the aphids as well as their food plants.

TL;DR: The Macrosiphini is one of the 2 tribes of the subfamily Aphidinae (Aphididae: Hemiptera) containing about 2166 species/subspecies assigned to 242 genera, and infesting hundreds of plant species belonging to several families.
Abstract: The Macrosiphini is one of the 2 tribes of the subfamily Aphidinae (Aphididae: Hemiptera) containing about 2166 species/subspecies assigned to 242 genera. Out of these, only 96 genera and 374 species are recorded from India infesting hundreds of plant species belonging to several families. The food plants of Indian Macrosiphini is catalogued alphabetically (aphid species-wise) in three parts. In this contribution, food plants of only 25 genera and 109 species of aphids belonging to the tribe Macrosiphini (Acutosiphon to Dysaphis) are catalogued. These aphids feeds on 400 plant species belonging to 79 families. Most suffered families are Asteraceae (81 species) followed by Rosaceae (35 species), Fabaceae (27 species), Brassicaceae (22 species), Lamiaceae (18 species) and Solanaceae (17 species). Among them, several species are crops of agricultural and horticultural importance. The update checklist of food plants of rest of Macrosiphini will be dealt in successive articles.

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.
