Abstract

The Insect transmission were conducted under green house
condition on pea plant plum pox virus has been able to be transmitted
by six different aphid species
Myzus persicae (70%) Aphis
craccivora
(50%) Hyalopterus pruni (30%) Rhopalosipinum padi (20%).
A. faba (10%) A. gossypii (10%) the virus transmissibility by aphid is
higher parallel to number of insect allowed acquire the virus plum pox
transmitted by nymph stage more than adult stage (75% and 32%)
respectively . Plum pox virus is beginning able to be acquired by
M.
persicae insect after 2 days post- inoculation period. The effects of
releasing
Chrysoperla carnea stephens larvae were tested with plum pox
viruliferous aphid. The Infection has been decreased with
Chrysoperla
carnea
releasing in the stage of M. persicae nymph. Finally, the results
made clear that the insecticides decrease virus infection than
C. carnea.
