Rate Of Diaspididae In Unabi Plant

Dangerous pest is widespread in Uzbekistan. The most dangerous of these are diaspids. They damage many plants. Unabi, apple, pear, plum, quince, peach, almond, hawthorn, pine, poplar and other orchards and ornamental trees are damaged. According to the taxonomic composition of the fauna of diaspids found in the unabi orchards of Tashkent region, the number of generations in the family Diaspididae in the fauna was 6 (Diaspidiotus, Salicicola, Parlatoria, Lepidosaphes, Chlidaspis and Pseudaulacaspis) and the number of species was 12. Diaspidiotus (4 species, 33,3%) and Lepidosaphes (3 species, 25,0%) predominate in the distribution of species, while Salicicola, Parlatoria, Chlidaspis and Pseudaulacaspis are monotypic. species, representing 16,7% of the total fauna, while representatives of the Salicicola, Chlidaspis and Pseudaulacaspis genera had 1 species, accounting for 25,0% of the total fauna.


INTRODUCTION
Today, diaspids, which are serious pests of fruit and ornamental plants, cost the agricultural and horticultural sector $ 5 billion a year. The U.S. dollar is hurting. Accordingly, the The American Journal of Agriculture and Boimedical Engineering (ISSN -2689(ISSN - -1018 Published: January 31, 2021| Pages: 59-65 Doi: https://doi.org/10.37547/tajabe/Volume03Issue01-10 IMPACT FACTOR 2021: 5. 554 OCLC -1121105746 identification of harmful diaspid species in fruit and ornamental trees, the development of measures to combat them is of great scientific and practical importance.
Today, the world's leading countries pay special attention to the study of the bioecology of orchard pests, which play an important role in the sustainable development of the agricultural complex and food security. Here, especially in the orchards of our republic, pests for almost all species and widespread California scale fruit trees are mainly unabi, apple, pear, plum, cherry, peach, cherry, apricot, as well as black currant, hawthorn, rose, from the forest and ornamental forest trees. willow, flowers, red fruit shrubs cause serious damage to plants.

MATERIALS AND METHODS
The research was conducted in Tashkent  Samples of diaspids belonging to 6 genera in the Diaspididae family were collected from different developmental stages of the total identified species. These insect specimens were collected in the offspring section as follows: Diaspidiotus 4, Salicicola 1, Parlatoria 2, Lepidosaphes 3, Chlidaspis 1, and Pseudaulacaspis 1.
The main materials were collected from the unabi gardens of Tashkent region in 2019-2020. In the study, the lower, middle, and upper tiers of the plant were examined to identify diffuse diaspids, and the diaspids were identified during the current wintering periods and at which stage of development in the food plant. Collection and storage of accumulated diaspids N.S.Borxsenius [6; -130 p.] Was carried out on the basis of the methodology. Collection materials were scaleed from the branches of the forage plant 10-15 cm long, in separate boxes, the specimens on the leaves were stored in a herbarium.
The study of the biological properties of diaspids began in the spring and was systematically monitored at weekly intervals. Observations were made using the bioassay method (once a day) in selected model trees based on the order of diaspids in the plant body, branches and twigs, as well as the order of diaspid distribution in fruits and leaves. In addition, when taking samples from diaspids, an attempt was made to take the trees on the circular sides of parts of the same height from the ground. Variation in the number of diaspids in the module trees, the life processes of laying eggs, the emergence of larvae, the emergence of males were also studied. OCLC -1121105746 transition of larvae from the first to the second year, barking, young females or males. The development of diaspids found in selected and isolated model unabi tree bushes was monitored on a regular basis (Tashkent region).

RESULTS AND DISCUSSION
The fauna and taxonomic analysis of diaspids found in unabi trees of Tashkent region were studied. The results of the taxonomic analysis of diaspids found in the unabi plant of Tashkent region are given below (Table 1).
