Abstract

This article provides information on the types of plant bugs, their damage, and measures to combat them in cotton agrobiocenoses of Uzbekistan. As a result of the conducted research, 15 species of bugs, of which Eurystylus bellevoyei (Reuter, 1879) species were identified for the first time in the cotton fields of Uzbekistan. In special experiments in the cages, it was determined that when 100-150 bugs correspond to 100 cotton plants during the vegetation stage of the cotton plant, cotton yield decreases to 32.3-36.4% owing to the effect of alfalfa bug (Adelphocoris lineolatus) and 8.6-13.5% owing to the plant bug (Lygus. protensis). If cotton is infected with a cotton shredder bug (Creontiades pallidus) in the early period (June), the yield of cotton decreases from 61.6% to 88.9%, if there are 30 to 150 plant bugs per 100 cotton plants. If it is infected later (July-August), the yield of cotton decreases from 38.0 to 50.2%. If fine fiber cotton is damaged by bugs (100-150 specimens per 100 cotton plants) during the vegetation stage, the cotton yield will decrease by 55.5-65.3% compared to the control variant. The most effective drugs against plant bugs are: Safegor, 40% (98.3%), Ribo Super, 25% (93.4%), Transform, 50% (92.5%), and Mosetam 20 (82.8-81.9%). Arvilmek 1.8 (active substance- abamectin), Lead, 5% (substance-pymetrozine), Imido Star, 20% (imidacloprid) were found to have unsatisfactory (below 70.0%) results against cotton bugs.

乌兹别克斯坦棉花作物的植物昆虫(异翅目:盲蝽科)发育及危害

本文介绍了乌兹别克斯坦棉花农业生物群落中植物害虫的类型、危害以及防治措施。根据所进行的研究，在乌兹别克斯坦棉田首次发现了15种昆虫，其中Eurystylus bellevoyei（Reuter，1879）种。在笼中的特殊试验中，确定了在棉花植株的植被期，当100-150只虫子对应100株棉花植株时，由于苜蓿虫子（Adelphocoris lineolatus）的影响，棉花产量下降到32.3-36.4%，而植物虫子（Lygus.protensis）的影响则下降到8.6-13.5%。如果棉花在早期（6月）感染了碎棉虫（Creontiades pallidus），如果每100株棉花中有30至150株植物病虫，棉花产量将从61.6%下降到88.9%。如果晚些时候（7-8月）感染，棉花产量将从38.0%下降到50.2%。如果细纤维棉在植被期被虫子破坏（每100株棉花中有100-150个样本），棉花产量与对照相比将下降55.5-65.3%。最有效的杀虫剂是：西夫戈尔，40%（98.3%），Ribo Super，25%（93.4%），Transform，50%（92.5%）和Mosetam 20（82.8-81.9%）。Arvilmek 1.8（活性物质-阿维菌素），Lead，5%（物质pymetrozine），Imido Star，20%（吡虫啉）对棉虫的效果不理想（低于70.0%）。

期刊介绍： WSEAS Transactions on Environment and Development publishes original research papers relating to the studying of environmental sciences. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with sustainable development, climate change, natural hazards, renewable energy systems and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
