Abstract: A new genus Indoidiopterus, with Capitophorus geranii Chowdhuri et al., as the type-species, and a new species, Eutrichosiphum pyri are described. Twenty-eight other species are reported as new records for the region. These include Dysaphis foeniculus (Theobald), Pleotrichophorus glandulosus (Kaltenbach), Thuleaphis ? amygdalinus (Schouteden), which are recorded for the first time from India. The hitherto undescribed alate viviparous females of Impatientinum impatiense dalhousiensis Verma and the apterous viviparous females of Periphyllus aesculi Hills Ris Lambers are also recorded.

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: 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 indigenous isolated strain of B. bassiana (deb4) has shown highest biocontrol potentiality amongst three indigenous entomopatogenic fungi under lab condition against A. gossypii and can be applied in agrifields.
Abstract: Papaya is economically important cultivated fruit crop grown in all tropical countries, having enormous nutritional values. Papaya Ring Spot Virus imposes a significant crop loss in terms of quality and quantity. To encounter the virus vector (Aphis gossypii), indiscriminate use of chemical pesticides creates severe environmental hazards whereas biological control is a perfect alternative to this problem. The objectives of our present study were isolation and characterization of indigenous fungi and their comparative analysis of entomopathogenic fungi against papaya aphid and finding its pathogenicity. Fungal isolates collected from natural sources were characterized and identified by the cultural and morphological study. Potential EPF genera were molecularly identified by PCR (ITS1-5.8S-ITS2) method. Entomopathogenic fungi were screened against A. gossypii for their pathogenecity by incised leaf disc method. LD50 (median lethal dose) and LT50 (median lethal time) were analyzed by regression analysis. Phylogenetic relationship among EPF was evaluated by MEGA software. Out of forty isolated entomopathogenic fungi, three (Beauveria bassiana deb4, Penicillium verrucosum Nlg1, and Fusarium equiseti khr4) were highly effective entomopathogen. The LD50 value of B. bassiana, P. verrucosum and F. equiseti were 1.4 × 104, 9.8 × 104, 1.0 × 106 spores ml−1, and LT50 values were 32.14, 37.5, 32.14 h respectively. Their phylogenetic analysis indicates related closeness on the basis of their conserved internal transcribed spacer region. In conclusion, the indigenous isolated strain of B. bassiana (deb4) has shown highest biocontrol potentiality amongst three indigenous entomopatogenic fungi under lab condition against A. gossypii and can be applied in agrifields.
