Influence of biologically active substancts on number aphid-vectors viruses

Abstract

It has been shown, that plant hormones (contents and composition) are factor in regulating active spread, inecease in degree of infection and widening of area Bean yellow mosaic virus and Bean common mosaic virus are formed as a result of adaptation of aphids vector to new tropic plants. The concentration of hormones affects the number of migrant stades vectors and their reproductive functions.
