TAXONOMIC ANALYSIS OF LONG-NOSE (WEEVILS) BEETLES (COLEOPTERA, CURCULIONIDAE) DISTRIBUTED IN SOUTHERN FERGANA
<p><em><span>Long-nosed (weevils) beetles weevils (Curculionidae) There are 63,400 species of phytophagous species common in all regions of Uzbekistan; As a result of research, 20 species belonging to 4 subfamilies and 8 genera of Curculionidae family were registered. Researches on the study of long-horned beetles in the territory of Uzbekistan and this list have important scientific and practical importance in studying the fauna and distribution of these beetles, as well as in determining effective pest control measures.</span></em></p>
