abstract myzus persicae sulzer is one of the serious pests in potato fields which has the ability of transmitting several viruses to the potato crop. throughout summer of 2008, field studies were carried out in ardabil to evaluate the seasonal population fluctuation of this aphid on 10 potato cultivars: granola, satina, moren, aozonia, cosima, agria, cosmos, kondor, diamant and savalan. density...

The vast majority of plant viruses are transmitted by insect vectors, with many crucial aspects the transmission process being mediated key protein–protein interactions. Still, very few vector proteins interacting have been identified and functionally characterized. Potato leafroll virus (PLRV) is most efficiently Myzus persicae, green peach aphid, in a circulative, non-propagative manner. Usin...

BACKGROUND The feeding of Bemisia tabaci nymphs trigger the SA pathway in some plant species. A previous study showed that B. tabaci nymphs induced defense against aphids (Myzus persicae) in tobacco. However, the mechanism underlying this defense response is not well understood. METHODOLOGY/PRINCIPAL FINDINGS Here, the effect of activating the SA signaling pathway in tobacco plants through B....

Radish is a short cycle horticultural product from family Brassicaceae. Between the insects found on radish leaves, potato green aphid (Myzus persicae Sulzer) one of main pests this culture, causing economic damage. Synthetic fertilizers used in conventional crops can promote changes pattern amino acids plants, leading to higher insect The source fertilization factors that could influence incid...

Organic mulches, like peel and rice-straw, besides other materials affect the UV and temperature, which cause a reduction in the aphid arrival. The aim was to evaluate the effect of covering the soil with straw on the populations of the green peach aphid, Myzus persicae on the kale, Brassica oleracea var. acephala plants. The first experiment evaluated the direct effect of the rice-straw mulch ...
