Sugescent Salicaceae Invaders (Insecta, Homoptera) of the South-Eastern Part of Central Asia

Abstract

The purpose of the research is to study fauna and dispersion of Homoptera attacked Salicaceae at the south-eastern part of Central Asia. Materials and methods. Authors’ longstanding works (during 2008–2018) on research morpho-ecological characteristics of sugescent invaders conducted in different regions of south-eastern part of Central Asia (Andijan, Fergana, Namangan) served as the material for the research.Results and discussion. It has been established that sucking insects (frog-flies, greenflies, coccids) referring to 70 species and 12 families of Homoptera class are attacked Salicaceae at south-eastern part of Central Asia. Potential Salicaceae invaders are greenflies Tuberolachnus salignus, Pemphigus bursarius, P. immunis, P. populinigrae, P. protospirae, P. vesicarius and Chaitophorus pruinosae and coccids Qudraspidiotus slavonicus, Drosicha media, Gossyparia salicicola, Lepidosaphes ulmi, Chionaspis salicis, Diaspidiotus ostreaformis and D. slavonicus. As distinct from leaf gall aphids (pemphigus) pachypleurous nucamentaceons plant galls Pemphigusimmunis and large pouch-like plant galls P. vesicarius forming on poplars branches and shoots remains unchanged also in winter months. Herewith greatly infected shoots become warped, get sleazy appearance and trees lose decorativeness.
