O’ZBEKISTONNING AYRIM SHAHARLARIDA QURUQLIK MALAKOFAUNASINING SHAKLLANISHI VA FAUNISTIK TARKIBI
Get PDFThe article analyzes the factors of the formation of terrestrial malakofauna in urbanized landscapes, the modern distribution of species and the origin of urban malakofauna based on ecological groups. Adventitious species are classified according to the degree of naturalization into domesticated, colonized and epecozoid species
UY SHAROITIDA TOVUQLAR ARGAS PERSICUS KANALARIGA QARSHI KURASH USULLARI
Get PDFCurrently, as in the rest of the world, poultry farming is successfully developing in Uzbekistan toensure the population\u27s food supply. However, one of the challenges hindering the development of this sector in bothindustrial and household poultry production is ectoparasitic diseases affecting birds. Among the diseases caused byarthropod ectoparasites in domestic poultry, especially chickens, the most dangerous is argasidosis. This disease inchickens is caused by the Persian tick, Argas persicus
THE IMPORTANCE OF DRAGONFLIES IN ALHAGI PSEUDALHAGI (M. BIEB.) DESV. EX WANGERIN PEST ELIMINATION
Get PDFDragonflies (Odonata), the oldest representatives of the class of insects are predatory insects andare important in biological control in natural processes. This article highlights the importance of dragonflies in theloss of plant aphids (Aphis gossypii)
QASHQDARYO HUDUDIDA TARQALGAN ORTHETRUM SABINA (DRURY 1770), NINACHI TURINI TAKSONOMIYASI VA MORFOBIOLOGIYASI
Get PDFIn this article, as a result of the monitoring of the odonata fauna of Kashkadarya during the years 2020-2023, the location, period, and morphobiology of the species Orthetrum sabina Drury 1770 belonging to the genus Orthetrum Newman, 1833 of the family Libellulidae are also presented
TAXTAQORACHA DOVONI MALAKOFAUNASI
No full textThe article found that 18 species of terrestrial molluscs were distributed in the Taxtakaracha pass, studied the density of distribution of 8 species in different biotopes, and found that the population density of Xeropicta candacharica and Candaharia levanderi species was high, revealing its causes
QASHQADARYO VILOYATINING YIRIK SUV OMBORLARI VA ULARDA UCHRAYDIGAN BALIQLAR
Get PDFThere are about 10 reservoirs in Kashkadarya region, the largest of which are Pachkamar, Chimkurgan, Qamashi, Hisorak and Talimarjon reservoirs. In this chapter of the work, we found it necessary to describe the large water reservoirs in our region. There are 11 species of fish in the reservoirs of Kashkadarya region, 6 of these species are acclimatized, and 5 are local species. 4 species of acclimatized fish (Carassius auratus gibelio, Ctenopharyngodon idella, Hypophthalmichthys molitrix, Stizostedion lucioperca) were introduced for specific purposes, while 2 species (Abramis brama, Channa argus) accidentally entered the water bodies of Uzbekistan
TABIIY SHAROITDA KIMYOVIY PREPARATLAR ASOSIDAGI TAYYORLANGAN ZAHARLI YEM-XO‘RAKLARNING TERMITLARGA QARSHI BIOLOGIK SAMARADORLIGI
Get PDFWhen Emamectin benzoate 5% toxic baits were installed in the field, the degree of feeding on mud-plaster and feeding by termites was higher than that of feeding (78.8-80.4%) and mud-plaster in 0.002% and 0.003% variants of the drug, respectively. and it was noted that the level of wrapping is 72.5%. These variants of the drug were recommended for use in the preparation of fodder.
 
The Cauchy problem for a double nonlinear parabolic equation with variable density and nonlinear source: The Cauchy problem for a double nonlinear parabolic equation with variable density and nonlinear source
No full textAbstarct. We have studied the propagation of heat in this article in an exponentially varying densityenvironment with double nonlinearity, in the presence of source. A self-similar solution has also beenfound for the issue under consideration
Effect of heat source on ambient density in double nonlinearity heat dissipation processes in multidimensional areas: Effect of heat source on ambient density in double nonlinearity heat dissipation processes in multidimensional areas
No full textAbstract. In this research, we investigate the modeling of cross-diffusion systems that are not inequilibrium. For a particular equation, it is shown that the parameter values exist and have a numericalsolution. A source describes the system of equations considered in this study as being based on themajority of physical processes, such as the cross-diffusion process in this system, thermal conductivity,and polytrophic filtration of gas and liquid in nonlinear media. Numerous partial solutions exist for theseequations
