ASSESSMENT OF THE SPECIES AND QUANTITATIVE COMPOSITION OF PESTS FRUIT CROPS IN THE CONDITIONS OF THE CITY OF PAVLODAR

In reducing the number of pests of fruit crops and the harm they cause, it is important to: in-depth study of the biological characteristics of the main pests; assessment of the impact of abiotic and biotic factors on changing the dynamics of their number; development of economic thresholds for harmfulness of these pests and evaluation of the effectiveness of individual methods of integrated control. The article presents the results of research on the species composition of garden crop pests on the territory of the city of Assessment of the dynamics of their number and its dependence on environmental factors, damage to cultural plants, determination of the threshold of economic harmfulness of species and justification, taking into account the feasibility of using chemical means of protection. In the year of observations, there was a mass reproduction of aphids, California shield, which was facilitated by moderate wet weather during the growing season. The number of observed pest species of fruit crops exceeded the threshold of economic harmfulness, which determined the need for chemical treatment with insecticides.
