Whiteflies are very small insects (1.5-2 mm), resembling microscopic moths. The wings and body are covered with white powdery pollen. They reproduce sexually, the eggs are attached to the underside of the leaves, on the stems. They hibernate in the puparia phase (pupa) on fallen leaves, in cracks and hollows of trees. The development is complicated: the larvae of the first age are mobile, the next stages are immobile. The larvae then develop into a pupa (puparium). One generation develops within 1 month. In greenhouses it can breed all year round and give 8-10 generations.
Scales damage many plants such as apples, pears, plums, quinces, peaches, almonds, hawthorn, pine, poplar and other orchards and ornamental trees. According to the taxonomic composition of the fauna of scales found in fruit and ornamental plants of Tashkent province in Uzbekistan, the number of generations in the family Diaspididae in the fauna is 18 (Diaspidiotus, Diaspis, Dynaspidiotus, Unaspis, Shansiaspis, Salicicola, Parlatoria, Lepidosapis, Lepidosaphes, Lepidosaphes, Lepidosaphes Carulaspis, Rhizaspidiotus, and Pseudaulacaspis), and the number of species was 30. Diaspidiotus (8 species, 26.6%) and Lepidosaphes (4 species, 13.3%) predominate in the distribution of species, while Diaspis, Dynaspidiotus, Unaspis, Shansiaspis, Salicicola, Parlatoria, Leucaspis, Aulacaspis, Aonidia, and Chon. The number of species of the genus Chlidaspis, Prodiaspis, Mercetaspis, Carulaspis and Rhizaspidiotus is monotypic, the representatives of the genus Parlatoria and Chionaspis have 2 species and account for 13.3% of the total fauna. Aonidia, Chlidaspis, Prodiaspis, Mercetaspis, Carulaspis and Rhizaspidiotus genus have 1 species, accounting for 46.7% of the total fauna.
Dangerous pest is widespread in Uzbekistan. The most dangerous of these are diaspids. They damage many plants. Unabi, apple, pear, plum, quince, peach, almond, hawthorn, pine, poplar and other orchards and ornamental trees are damaged. According to the taxonomic composition of the fauna of diaspids found in the unabi orchards of Tashkent region, the number of generations in the family Diaspididae in the fauna was 6 (Diaspidiotus, Salicicola, Parlatoria, Lepidosaphes, Chlidaspis and Pseudaulacaspis) and the number of species was 12. Diaspidiotus (4 species, 33,3%) and Lepidosaphes (3 species, 25,0%) predominate in the distribution of species, while Salicicola, Parlatoria, Chlidaspis and Pseudaulacaspis are monotypic. species, representing 16,7% of the total fauna, while representatives of the Salicicola, Chlidaspis and Pseudaulacaspis genera had 1 species, accounting for 25,0% of the total fauna.
Fungal species were isolated from samples of damaged sunflower. The strains selected on the basis of cultural and morphological characteristics belonged to the species Alternaria alternata, Alternaria tennus and Fusarium oxysporum, Fusarium solan, and fungal strains were identified, as well as fungal strains, and fungal strains 67, termites, termarium, oxolbate 10, oxoliban 10 - to termites, oxolbate 10 - to termites, oxolbate 10.9%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
