Abstract
The article presents monitoring data on the identification and determination of the species composition of phytophages and phytopathogens of ordinary hop plantings in the Chuvash Republic in conditions of high temperatures and a dry summer of 2018. Studies were conducted on hop plantations in the hop-growing enterprises of the Chuvash Republic in 2018. Methods of identifying, accounting for pests and diseases were carried out in accordance with the methodological recommendations on the forecast of development and accounting of pests and diseases of agricultural plants. Observations on the species composition showed a stable structure of the species community. Against the background of high summer temperatures and droughts, there was a clear inhibition of pest populations, at the same time some species of phytophages felt well and adapted to these conditions, completed development cycles favorably, and left for wintering quite a lot. The greatest damage to hop planting this year was caused by an ordinary spider mite. The timely detection and localization of foci of spider mite gave the opportunity to prevent the spread, control the number and harmfulness.
