Abstract
The pea aphid Acyrthosiphon pisum (Harris) is considered as vector for numerous plant viruses, including Pea enation mosaic virus (PEMV)). Experiments confirmed the ability of A. pisum adult to acquire and transmit the virus to pea plantations in Dakhlia Governorate, Egypt.
The acquisition  threshold feeding  period  ranged 1-20  min   from   infected  pea   plant  to healthy  celery and   from  infected celery   plant  to  healthy  one  15– 25 min. Moreover retransmission  from  infected  celery  plants   to  healthy  pea plants  10  - 20 min. On the other hand inoculation threshold feeding period ranged from15-25 sec. The incubation period in A. pisum was 4-6 hours but in pea plants ranged from 8-11 days and in celery plants 7--9 days. The Retention   period of Pea enation mosaic virus (PEMV) in A. pisum was 4 - 5 days)
Results of this study will help to understand the epidemiology of Pea enation mosaic virus (PEMV)) in pea plantations .Also the pea plants and virus vector relationships of Daklia isolate are reported for the first time.
Conclusively, it can be concluded that transmission experiments proved that pea enation mosaic virus is transmitted by A. pisum in a persistent manner.
