Prognosis of reproduction of malicious generations Lobesia botrana in conditions of plain-steppe of Crimea

Abstract

Provides information on the intent of the development of
malicious generations Lobesia botrana of the leaf roller
on vine plantations of plain-steppe Crimea from abiotic
factors: the average daily air temperature, amount of precipitation,
relative air humidity, as well as the area of leaf
surface bush of grapes. On the basis of these data
developed mathematical models of forecasting of the
development of the phytophage, that allows to optimize
the frequency and timeliness of protective measures in
the fight against this pest on a particular cultivar of
grapes.
