Biological Control of Weeds: Southeast Asian Prospects

A total of 14 genus and 108 species synonyms in family Aphididae are listed with explanations and comments. Synonyms involving aphid names in the economic literature include: Acyrthosiphon bidentis Eastop 1953 = Acyrthosiphon ilka Mordvilko 1914; Aphidura mingens Pintera 1970 = Aphidura picta Hille Ris Lambers 1956; Aphis armoraciae Cowan 1895, Aphis maidiradicis Forbes 1891 and Aphis menthaeradicis Cowan 1895 = Aphis (Protaphis) middletonii Thomas 1879; Diuraphis ( Holcaphis ) agropyronophaga Zhang, 1991 = Diuraphis ( Holcaphis ) tritici (Gillette, 1911); Sitobion chanikiwiti (Eastop 1959) and Sitobion howlandae (Eastop 1959) = Sitobion leelamaniae (David 1958). An annotated list of 36 other proposed nomenclatural changes is provided.

Some new synonyms in Aphididae (Hemiptera: Sternorrhyncha)

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.

The sugarcane woolly aphid, Ceratovacuna lanigera Zehntner (Hemiptera: Aphididae): its biology, pest status and control

Aphididae of Formosa

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.

Natural Enemies Associated with Aphids and Coccids from Sikkim, India

Extensive collections of aphids from cultivated and wild plants of North Bengal and Sikkim reveal ten new species and subspecies : Akkaia neopolygoni, Aulacorthum rhamni, Greenidea longicornis, Macrosiphum spinotibium, Macrosiphum (Sitobion) plectranthi, Megalophyllaphis obscura, gen. et spec, nov., Megoura cajanae, Neoacyrthostphon rhododendri, Neoacyrthosiphon taiheisanum ovalifolii and Tinocallis distincta. 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.

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.
