MONITORING OF THE WALNUT FRUIT FORESTS IN KYRGYZSTAN

Abstract

The article presents data from the analysis of monitoring of walnut forests in Kyrgyzstan. The main dominant pests were identified as gypsy moth (Lymantria dispar L.) and cherry slimy sawfly (Coliroa cerasi L.). The foci of gypsy moth (Lymantria dispar L.) were identified in pistachio plantations in forests and forestries. The dynamics of the number of populations of gypsy moth caterpillars was recorded and their bioecological features were studied. According to the materials of forest pathological surveillance in the summer since 2014, forestry enterprises and forests have been observed continuous grazing by cherry slimy sawflies (Coliroa cerasi L.) of hawthorn plantations of walnut forests. Some biological features and morphology of the insect have been studied. In order to reduce the number of gypsy moth (Lymantria dispar L.) in the laboratory and in the field, a new biological preparation "Bactocid VK33" was tested at concentrations of 1:100; and cherry slimy sawfly (Coliroa cerasi L.) - "Aktarofit 1.8" at concentrations of 1:200.
