The article examines the biological characteristics, patterns of distribution of the 1st class of
key pests of fruit trees in Kazakhstan - aphids (Aphididae), as well as the equipment for their
adaptation to climatic changes. The most 90% of fruit trees in Kazakhstan are decorated with apple
(Malus), pear (Pyrus), cherry (Prunus), plum (Prunus), apricot (Armeniaca) and peach (Amygdalus)
crops. All of these plants, without exception, belong to the genus Rosaceae. In recent years, in
conjunction with changes in the atmospheric climate, the structure of pests has changed, their
population has increased, as well as the duration of their formation. The study was based on
methods of phytosanitary forecasting. In the process of entomological studies, methods of
convocation, plant conservation, morphological examination, as well as statistical processing of
information were used. In the spring, aphids rapidly multiply in fruit trees, and by the middle of the
year they are transferred to herbaceous plants. They feed on plant juices, violating physical
movements, which leads to a decrease in the yield of fruit civilizations. The note shows ways to
identify, summon, and preserve aphids. In addition, methods for modeling their distribution,
controlling the number, and using facets of protection to improve the built-in concept of plant
protection are being considered. This study provides an opportunity to better understand the bio
characteristic features of plant pests and assess their impact on fruit-bearing trees. During the study,
2 subfamilies of aphids (Eriosomatinae and Aphidinae) from the family Aphididae were identified,
from the Twentieth to 51 types were recorded. The promotion of varieties was designated according
to the concept of A.F. Yemelyanova. Agents of the subfamily Eriosomatinae are considered
heterocytic (omnivorous) and oligophagous (they feed on a narrow number of plant species). Their
main owners are considered to be a plant (Crataegus), a flashlight (Malus), a fruit (Pyrus) and a pine
tree (Pinus). Agents of the Aphidinae subfamily are found in different plants, and monophages (they
feed on one type of plant) and polyphages (they are found in a large number of varieties) are often
found among them. The main owners are Spiraea, Prunus, Amygdalus, Armeniaca, Crataegus,
Malus and Pyrus. This study can become a basis for establishing the biodiversity of aphids living in
rice and agricultural plants in Kazakhstan, as well as for exploring the productive facets of pest
control.
