Biljne vaši roda Chaitophorus na topolama u Srbiji

Abstract

In the area of cultivation of poplars in Serbia, in recent years it has been increasing numbers of plant lice. Due to the increasing number of lice on plants, there were recordings of numerous and various plant injuries like chlorosis, deformation of leaves, forming of gals and leaf nests. It resulted with reduced development of plants, health status and in some cases caused the decay of entire plants. Researches were conducted in the period from 1997 to 2011. Five aphid species from genus Chaitophorus, were determined on poplars in Serbia. These species were Chaitophorus leucomelas Koch, 1854, Chaitophorus nassonowi Mordvilko, 1894, Chaitophorus populeti Panzer, 1801, Chaitophorus populialbae Boyer de Fonscolombe, 1841 and Chaitophorus populifolii Essig, 1912. Most affected were the clones of black and white poplars. Also, the paper provides basic morphological and biological characteristics of the identified species. .Tokom istraživanja entomofaune biljnih vaši na topolama, koja su obavljena u periodu od 1997. do danas, utvrđeno je pet vrsta vaši roda Chaitophorus. Rod Chaitophorus je najbrojniji na topolama u Srbiji. Biljne vaši ovog roda predstavljaju ekonomski najznačajnije štetočine u rasadnicima i mladim zasadima topola. U radu su date osnovne morfološke karakteristike, biologija, biljke domaćini i štetnost vrsta.
