The study results on prevalence of the main harmful insects on the mother planting of the basic grape plants of the Rostov region: rose leafhopper, buffalo treehopper, tree cricket, tobacco and grape thrips, which are polyphagous phytophages, are presented. As a result of the negative impact of harmful organisms the plant normal development is disrupted. The spread and increase in the insect harmfulness in the Rostov region is facilitated by an increase in the average annual temperature to 9.5-11.6 °C in the last 10-15 years, which is the lower limit for their survival. A close direct relationship was revealed between the average annual temperature and the leafhopper and thrip harmfulness: r=0.72-0.89 and an unobvious dependence of the tree cricket harmfulness on thermal conditions (r=0.59). The phytosanitary control system in the mother planting made it possible to restrain the harmful organism development, with a harmfulness not exceeding 1.3 points for thrips and 2 points for other insects for further reproduction of practically healthy grape planting material while maintaining the status basic plants.
