Abstract
Zucchini
yellow mosaic virus (ZYMV) is an important non- persistent virus causing high squash
production losses in Egypt. Aphis gossypii Glover and Myzus persicae
Sulazer insects have high efficiency of ZYMV transmission from infected squash
plants to healthy ones in Egypt,in advance of their rapid spreading. ZYMV was isolated from
naturally infected squash plants collected from two locations (Sennoris &
Fayoum), at Fayoum governorate. Virus identification was done by
serological tests (ELISA) using four different antiserums. Virus was
transmitted to healthy squash plants by mechanical transmission and by using the
two aphid insects. Fecundity and life span of two aphids and
forms (alate and apterous) were studied. ELISA test had relay that the virus
was ZYMV. Typical symptoms of virus were observed by mechanical and aphid
insect's inoculation,
yellow
mosaic, necrosis, leaf curling, blisters stunting, deformation, reduction in
leaf size and knobbed fruits (sever malformation).
Fecundity and life span of
Aphis gossypii were higher than those
of Myzus persicae on infectedsquash plants
compared with healthy, respectively.The reducing aphid insects population is
recommended in order to decreasing losses caused by ZYMV infection (as their
ability of transmission), in addition of removing the infected plants
continuously which considered as a source if virus inoculum
