The city's bearded beetle (Aeolesthes sarta (Solskiy, 1871) is widely spread in the southern regions of Central Asia and is one of the most dangerous pests of ornamental and fruit trees as a touristic destination with a wide range of nutrients. Although studies on the distribution, damage and countermeasures of the city's bearded beetle have been conducted, its biology and life cycle have not been studied extensively in the Fergana valley. Aeolesthes sarta specifically, these beetles have the ability to select reproduction, growth and nutrition as other insects. The herd beetles mate in the second decade of March and start to put their eggs in the next ten days of April. Mating is usually becoming active after the sunset. The most active movement of insects is at 1900-2200pmin the evening. The most important factor in the development of the egg is moisture and temperature. Therefore, their eggs grow in the bark and the cobble in the tree. The whitened leaf is becoming black. Warms expelled in the end of April in early May eat actively until th third decade of October. The body of the plant is particularly damaging to the pharmacy. Tree damaged by bearded beetles are becoming unsuitable for construction. Especially, soft-torn trees are more damaged by the bearded beetles. For example, if there are 30 to 50 holes in the strongly damaged 1 meter body of the plane tree (December 29, 2008, Fergana), this figure is about 200 (18.01.2009, Uzbekistan). It was found out pests caused more damage by other family members than trees break down. In developing long-term beetle-fighting methods, it is desirable to take into account the phases of development in the second half of May, the duration of flight and the day's sunset.
