The invasive stink bug species Halyomorpha halys (Stål, 1855) (Heteroptera: Pentatomidae), a dangerous pest of many agricultural plants, is recorded from Uzbekistan for the first time. Several imagines and larvae were found in the Khorezm and Ferghana provinces in 2020 and 2022.

This article presents the results of scientific research conducted in 2019-2021 on the study of species belonging to the Pentatomidae family distributed in Uzbekistan. Also, the information was filled from the collection materials and literature kept at the Institute of Zoology of the Academy of Sciences of the Republic of Uzbekistan. A complete list of 3 subfamilies (Asopinae, Pentotominae, Podopinae), 10 tribes, 46 genera, 3 subgenera and 103 species belonging to the Pentatomidae family is provided for the first time in Uzbekistan. In the fauna, the specie of Alloeoglypta pretiosa Kiritshenko, 1952 was recorded for the first time. The purpose of this study is to present new records and an updated checklist of the Pentatomoidea of Uzbekistan. Also, the results of the scientific work conducted by various researchers on the study of the species of bugs belonging to the Pentatomidae family distributed in Uzbekistan and material of the collected species were deposited in the collection established by the fourth author, which is kept in the Laboratory of Institute of Zoology of the Academy of Sciences of the Republic of Uzbekistan.

A.ahngerianus Jacobs (Hodotermitidae) is a species of subterranean termite causing damage in Central Asian cities. Despite its economic importance, there has been no research on its basic biological aspects for laboratory management and control strategies. The aim of this study was to evaluate relative humidity, temperature and to identify other water sources that A. ahngerianus may use for best survival under laboratory conditions. Other water sources that termites can use were identified using a range of six relative humidity levels (10 to 100%) and three temperatures (25, 30, and 35 °C). These included metabolic water from food decomposition, fat body water, free liquid water, groundwater, and water bound to various substrates (e.g., wood, soil, and chick carcasses). The results of this study showed a significant influence of all factors on termite survival or termite preference. At 100% humidity and 25 °C, A.ahngerianus had the highest survival rate, reaching 89.62% after three days of observation. Based on these preliminary analyses, it was concluded that with the appropriate percentage of humidity, further studies using biologically relevant conditions can be conducted to investigate different aspects of A.ahngerianus biology.
