| 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. | ||
