The article presents the possibilities of obtaining hybrids under unfavorable conditions of the Republic of Karakalpakstan using new hybrids and obtaining high yields of silkworm cocoons. The materials of the ecological point of view of the territories with the participation of sex-labeled rocks at the Grena stage are presented. And also the determination of the adaptability of the new Navruz-3, Navruz-4 hybrids and hybrids with the participation of parthenoclones of the agro-industrial complex x Labeled-1 hybrids to the extreme conditions of caterpillar growing.
The article is stated the socio-economic development of the fodder base of in Namangan region. In particular, analyzed the current state of the silkworm fodder base, negative consequences of its reduction. Studied research works of Uzbek and foreign scientists, as well as presented the laws and regulations for the development of the silk industry in our republic. Given scientific recommendations for the advantages and opportunities of the development the fodder base of the silkworm in the Namangan region.
In the case of rearing silkworm caterpillars, the caterpillar does not feed well with infected leaves, which leads to a decrease in the number of cocoons (73-76%) during the transition by instars, the larval stage lasts, the extension of the fifth instar compared to the growth options (89%). It turned out that the yield of cocoons decreased by 13-18% and 1 box decreased by 21-25 kg.
Preventive measures play a crucial role in ensuring the health and productivity of silkworms in silk farming. In this study, we focus on the implementation of preventive works using a mechatronic system to increase the weight of silk. Disinfection is recognized as a vital tool in combating silkworm diseases by neutralizing pathogenic microbes. The disinfection process targets worm houses and areas where disease transmission is more prevalent during warm feeding. By eliminating potential sources of infection, final disinfection is carried out at the end of the current worm feeding season, particularly in locations with a higher incidence of infectious diseases among silkworms. The integration of a mechatronic system in the preventive measures demonstrates its effectiveness in promoting healthier silk production.
This research focuses on the implementation of a remote control system in mobile silkworm houses to improve the weight and quality of silk fibers. The use of a lightweight and portable worm house, equipped with a mechatronic system, resulted in significant improvements in the weight and quality parameters of the obtained silk fibers compared to the traditional method. The integration of special sensors within the greenhouse allows for remote monitoring of CO2 levels. In case of CO2 exceeding the permissible limit, the ventilation system can be remotely activated, and it will be deactivated once the CO2 levels return to the normal range. Comparative analysis was conducted between the silk yield from the mobile worm house and other conventional worm houses, demonstrating the favorable outcomes of the portable wormery with the mechatronic system.
The methodology for obtaining biologically active substances is given: phytol, isophytol, tokferol, phylloquinone and their application in medicine and the national economy.
This article presents the results of examination of horses for helminthiasis in Ellikkala district. The average incidence of helminth infestation in the examined horses was 6.6%, stronglidiosis -6.6%, and parascaridiosis -20%. The overall infestation with helminths averaged 33.3 percent. “Panafenb”, a 22.2% drug for helminthiasis in horses, was found to be effective when given orally (per os) in the form of granules to horses in the amount of 1.0 g per 34 kg of live weight.
In the research work, it was proved that the silk yield depends on the hybrid, weight, hardness, size and thickness of the cocoon shell of the silkworm.
At the same time, it has been studied that the initial processing modes of the cocoon, storage, sorting, evaporation of the cocoons and spinning of the cocoons have a great impact on the output of raw silk. The thickest part of the cocoons is the waist, which varies from 0,14 mm to 0,45 mm. These figures also indicate the anisotropy of the cocoon shell. In order to reduce the anisotropy of the cocoons, we found a noionogenic SАM to obtain the solution and process the cocoons. We prepared different concentrations from the obtained SАM and studied their absorption into the cocoon shell. As a result, in the study, it was found that the cocoons were treated with a 0,1% SAM solution to determine the wetting and permeability properties, which improved the yield of raw silk. As a result of cocoon processing, the output of raw silk increased by 4.36% compared to control, the output of silk increased by 3,37%, and the output of cocoon skin decreased by 2,27%. The specific consumption of cocoons was 2,76 kg.
Biological and productivity indicators of imported Kinsyu and Syova breeds were studied in the conditions of Uzbekistan. In the experiment, it was found that the duration of the worm period of the Kensyu breed was one day shorter than the Asaka breed and the viability of the worms was 6% higher. In the Syova breed, the duration of the worm period was found to be 0.5 days shorter and the survival rate was 9% higher.
Based on a wide range of sources and literature, this topic is consider. It was found that the Fergana economic region, which takes place not only in the Central Asian economic region, but also in the economic life of the entire country, has become a region that provides the country with light industry, food and chemical products in the past and present. Considered also in addition to the presence of various natural resources in this economic region, cotton growing, silkworm breeding and fruit growing are very well developed. In addition, the article analyzes the structure of the Fergana economic region and its role in the national economy.
In the present paper the analysis of results of experiences carrying out on testing 5 hormonal affecting insecticides in fight against of mulberry pylalides from biologic active substances, namely Match – 1.0 litter/hectares, Nomolt – 0.3 litter/hectares, Binsegard – 0.5 kilogram/hectares, Al’familin – 0.5 litter/hectares and Rimon star 0.15 litter/hectares has been presented. In these experiences the values of the reached biologic efficiency in period of 15-16 days ones using were 81-100%. Therefore the preparations mentioned above for including to the list of allowed pesticides in agriculture of Uzbekistan for practical using them by farmers producing silkworm cocoons have been recommended.
This article presents the results of studying the prevalence of echinococcosis among large horned animals in the Samarkand and Surkhandarya regions and hematological blood parameters in animals heavily or weakly infected with echinococcus in the wild. In Samarkand region, 8.8% of cattle were infected with echinococci, and in Surkhandarya region - 14.3%. Decrease in the amount of erythrocytes and hemoglobin in the blood of cattle infected with echinococcosis (20-30%), increase in the number of leukocytes by 30-55%, and a significant increase in the number of eosinophils and lymphocytes in the leukoform, a decrease in neutrophils compared to control (3.25-6.5%). lymphocytes increased by 5.3-15.3%.
