INTRODUCTION belonging to 34 families. Among them, cotton, The main phytophagous species found in the cotton alfalfa, tomato, sugar beet, corn, grain, oilseeds are agrobiocenosis: Several phytophages were found the most popular food of autumn night. in the cotton agrobiocenosis during the research (Alimukhamedov Khojaev 1987) According to our conducted in the areas affected by the natural observations, in the first half of August, when disaster of Syrdarya region. The process of damage seedlings were planted in autumn night to cotton was observed mainly by spider mite, greenhouses, the presence of middle-aged and old autumn nightworm, bollworm, caradrina, plant worms was observed. Later (during the pruning aphids, caterpillars, cotton mite, thrips. (Ergashev period) the autumn night did not harm the plants. 2023) The types of these pests and their biological At the same time, it was observed that butterflies of features are as follows. the pest flew into the greenhouses and laid eggs. Agrotis segetum Den.et Shsiff. It is found But because there was not enough food in these everywhere in the conditions of our republic. This lands, the pest could not develop. pest damages more than 150 types of plants Cotton bolworm - Helicoverpa armigera Hbn.

The level of harmfulness has also been of the tomato that has entered the field. The 1st- studied, and the most common are cotton year-old worms that hatched from the eggs first bollworm, autumn bollworm, tamki bollworm, and feed on the leaves at the point of growth, then the wild bollworm. 2-3-year-olds damage the pods and flowers, and During cotton ginning period, 10 female butterflies, the older worms damage the fruit and make it unfit which were flown and fertilized from the for consumption. The worm hatched from the egg mushrooms collected from nature, were released develops in greenhouse conditions for 25-30 days to the designated areas. The next generation of and destroys 20-25 pods, flowers and fruits [1, 2, 4, butterflies was studied in the rest of the pieces [7, 5, 6]. 8, 9, 10, 11]. In areas where the bollworm is not controlled, it Observations were made every 3 days until the can destroy 70-80% of vegetable crops and 35- butterflies laid eggs and died. Observations 40% of cotton crops when it multiplies. According revealed that butterflies continued to lay eggs on to information provided by domestic and foreign the cotton plant for 12 days. authors, the cotton bollworm damages more than 250 plants. Distribution of species of tunlams that damage agricultural crops in the flooded areas of Syrdarya The bollworm damages the flowers, bolls and bolls region was statistically analyzed by Dospekhov of cotton, as well as corn stalks, tomato fruits, okra, 1985y methods from the results of experiments hemp and chickpea buds, pea pods and fruit organs during the year in "Hosilabad f/x" Guliston district of many other plants. Damaged combs and young of Syrdarya region, "Bek kalaster" of Mirzaabad nodes are often shed, and the bollworm sometimes district, "Inderama cluster" of Sardoba district. damages the stem tips. The results of the experiments were statistically Distribution of species of weeds that damage analyzed according to the methods of Dospekhov agricultural crops in flooded areas of Syrdarya 1985. region in "Hosilabad f/x", Gulistan district of Syrdarya region, "Bek kalaster" of Mirzaabad Monitoring of the spread of cotton agrobiocenosis district, "Inderama cluster" of Sardoba district in and their development in flooded areas of Syrdarya 2021-2023. region in January-March 2021-2023 (Guliston- "Hosilabad f/x", Mirzaabad-"Bek kalaster", In cotton agrobiocenosis, the occurrence of Sardoba-"Inderama cluster" areas 2021-2023). tunlams was shown to be somewhat higher than in Table 1 In our research conducted in the 1st quarter, the incidence of pests in the Mirzaabad area of Tunlam compared to the Gulistan district was lower in January-March Level of encounter A non- flooded Flooded area area № Latin name Uzbek name n d a d a ) r a a m) a t b a) b a ke t b oa r e s i l u G l i s o H x / f a z r i M e B ( s a l a K d r a S r e d n I t s u l c ( ( Order Leridoptera.
