| Abstract |
A field experiments were carried out in Beni-Swcif region during 200412005 and 2005l2006 seasons to detect aphid species and population density throughout two plantation dates on eight sugar beet varieties, in addition to their susceptibility to beet mosaic virus infection. All varieties were infested with two species of aphid; Alyzus persicae and Aphis fabae. The later insect was more abundant than M. persicae. ['he results assert that aphids have capability to attack all sugar beet varieties. Oscar and Pleno varieties were the highest resistant varieties while Gazelle and Gloria were the highest susceptible varieties for BtMV infection. The infected plants with both aphids and BtMV showed a reduction of root weight percentage r::n.;ed from 41.1 to 54.0%
A virus was isolated fron. sugar beet (Beta vulgaris L.) and was identified according to symptcnaatolngy, host range, physical properties, modes of transmission, ELISA, and hybridization test. Isolate of beet mosaic virus (BiMV) has visible symptoms on sutne hosts. Physical properties of the virus were, dilution end point lU-3, thernial inactivation point 55-60 C and lost infectivity after 2 days. The virus k,a:= c.:e.hanicatly transmitted as well as Myzus persicae insect. ELISA and non-radia:iac-uve molecular hybridization methods can be used for the detection of virus. 1'nt -iological effects of BtMV on sugar beet plants were studied. Infected piant:a :;iiowed more reduction in total sugars, reducing sugars, non reducing sugar.:, total carbohydrates, total free amino acids than healthy ones. On the other hand, phenol content was more high in the infected plants than healthy ones.
