Actual problems of modern science, education and training

Materials and methods. Place of work: For present studies adult specimens were collected from wheat crop adjacent to the private farm at Chalish district 15^th February to 15^th of June 2022. Further identification and examination were carried out at Entomology laboratory in Institute of Zoology Academy of Science of the Republic of Uzbekistan.
Method of collection: Collection was made through sweep net and pooter from selected wheat field.
Methods of killing and preserving: Specimens were killed in a jar containing ethanol 96 % and mounted through entomological pins, further specimens were labeled.
Methods of identification: To identify the specimen up to the species level, specimens were run through the keys for the region was collected from various publications.
Results. In present study total 5 species were discovered under order of Hemiptera. True bugs were found with 3 species Carpocoris pudicus (Poda, 1761), Carpocoris fuscispinus (Boheman, 1850), Eurydema ornate (Linnaeus, 1758) family Pentatomidae Leach, 1815, subfamily Pentatominae W.E.Leach, 1815 and tribe Podopini Amyot & Serville, 1843; one species under family Scutelleridae Leach, 1815, Eurygaster integriceps (Puton, 1881); one species under family Lygaeidae Schilling, 1829 and subfamily including; Lygaeinae Schilling, 1829 Graptostethus servus (Fabricius, 1787).
Discussion. Bugs are sometimes very notorious as an agricultural pest, their mouthparts are piercing and sucking, thereby make them capable of feeding directly on a crop and as a vector of plant diseases, the records in present study include; Carpocoris pudicus (Poda, 1761), Carpocoris fuscispinus (Boheman, 1850), Eurydema ornate (Linnaeus, 1758), Eurygaster integriceps (Puton, 1881), Graptostethus servus (Fabricius, 1787).
Insect biodiversity on wheat crop earlier was not considered as a harmful element, but due to the recent changes in climate and introduction of new varieties several insects are recorded on wheat crop in Chalish district of Khorezm region. (Figure 1)

Figure 1. Map of Study Area

Some insects are common visitors of wheat crop including aphids, but they usually been under check by their natural enemies as they voraciously fed by Coccinellids and Chrysoperla. In present study Phenological development of Eurygaster integriceps species were considered only. The crop has two critical periods of being attacked by insects’ first Seedling and other is flowering phases. [4, p. 775- 788]
In 2021-2022 years, the result of observations showed in Khorezm region, it was found that in the districts where grain is planted, bugs started to emerge from the first ten days of March-April. Egg lays proceed from the 2nd ten days of April to the 2nd ten days of May. The first larvae appeared in the 2nd-3rd ten days of April, and larvae were found until the middle of June (1-table).
