Representatives of Lepidoptera groups in the biotecenosis of Uzbekistan and their effective parasite-entomophage types

Abstract

In this article, we traced the development of fauna, bioecology and populations of more than 50 species of the main family Lepidoptera, found in the biocenosis of Uzbekistan. Research has been conducted in agricultural crops, forestry and natural biocenoses, and representatives of the Lepidoptera family have been involved in scientific research on species that cause great economic damage. Trichogrammatidae, Braconidae, Ichneumonidae, Chalcididae, Pteromalidae, and Tachinidae, the main entomophagous species that effectively control the number of members of the Lepidoptera family, have also been identified and systematically analyzed. The representatives of the family Trichogrammatidae, which are effective parasitic entomophagous in the management of the number of representatives of the family Lepidoptera. The study revealed that in the agrobiocenoses of cotton, mung bean, corn and cabbage in Tashkent province, the level of occurrence of three main species of nightshade pests of the family Trichogrammatidae, which are egg parasites of the family Lepidoptera, was determined. This means that the number of nights can be effectively controlled by members of the trichogramma family.

Efficiency of agrotechnical and chemical measures in control of weeds in onion (Allium cepa L.) fields

“…Providing context to the scale of the weed challenge, research conducted in Russia reveals that agricultural fields harbor an astonishing average of 100 million to 3-4 billion weed seeds per hectare. This statistic emphasizes the pervasive nature of weed proliferation, necessitating comprehensive and proactive measures to manage and mitigate their impact on crop growth and yields [10][11][12][13][14]. Implementing sustainable weed control practices becomes essential not only for preserving the nutritional integrity of cultivated crops but also for securing the economic viability of agriculture on a broader scale.…”

Indicators of valuable economic traits of hybrid F2 generations obtained with the participation of parental forms of different genotypes

“…Economic valuable traits of complex hybrids, including fiber length, its quality indicators, increase from lower generations to higher generations under the influence of separation and recombiogenesis. As a result of multi-year research by recrossing the introgressive samples obtained on the basis of the crossbreeding of different types and subspecies of cotton, which are sharply different in ecological and genetic origin, with different varieties, a number of new 176, 259, 311, 440, 700 ridges were obtained, whose fiber quality meets high international standards [5,6]. The expediency of carrying out the selection work on the fiber length sign depending on the genotype of the parent-mother forms involved in the crossbreeding and the possibility of distinguishing the forms whose fiber output is 5% superior to the model variety as a result of complex hybridization.…”

Investigating stimulated ripening indicators of longbeak rattlebox (Crotalaria) planted in the coasts of the Aral Sea

“…In 2008, $85 million worth of wheat was sold in Alabama. Here, it was found that the reason for the higher yield than wheat was that the legume srotalaria juncea was planted in these fields before wheat [10][11][12][13].…”
