DOMINANT INSECT PEST SPECIES THAT DAMAGE WILD POPULATIONS OF THE SIEVERS APPLE TREE (MALUS SIEVERSII) IN THE ILEY ALATAU

Abstract

The article is devoted to the problems of conservation of wild populations of the Sievers apple tree (Malus sieversii) in Kazakhstan, which are of global importance as a natural genetic basis for the maintenance and production of apples worldwide. Unfortunately, over the past half century, the area of growth of wild populations of this type of apple tree has sharply decreased, so the issues of preserving apple forests require special attention. One of the main threats to the existence of wild populations of the Sievers apple tree in the last 20 years has become insect pests that cause enormous damage to natural populations. In this regard, the purpose of the publication is to determine the degree of damage to the Sievers apple tree by three main pests (Yponomeuta malinella Zell., Archips rosana L., Cacoecia crataegana Hb.) in the Iley Alatau in 2018, 2019. A map of the distribution and influence of the apple ermine moth (Yponomeuta malinella Zell.), roseate leaf roller (Archips rosana L.), hawthorn leaf roller (Cacoecia crataegana Hb.) on the territory of the Ile-Alatau GNPP is also given.
