Abstract. Ruzmetrov R, Abdullaev I, Gandjaeva L, Matyakubov Z, Iskandarov A, Otaev O, Ibragimov S. 2022. Fundamentals of using Geographical Information Systems in predicting the distribution of Helicoverpa armigera (Lepidoptera: Noctuidae). Biodiversitas 23: 3251-3256. This study aims to explore new ways to identify agroecological conditions that help in the occurrence of Helicoverpa armigera in cotton fields. Geographical data on soil salinity, mechanical composition, groundwater level, salinity, density of canals and drains, field Normalized Difference Vegetation Index (NDVI) coefficient of the field Helicoverpa armigera with the number of eggs regression was analyzed. The data were collected from the database of the GIS laboratory of the KRASS (Khorezm Rural Advisory Support Service) agro-consulting center, which was established with support from ZEF (The Center for Development Research) University of Bonn, Germany, and lancet satellite data in the calculation of NDVI. Data were analyzed with ArcGIS and R program. Occurrence of Helicoverpa armigera in cotton fields was found to be associated with high relative humidity and high stem length. Using the relative humidity of the air in the field and other agroecological factors, it was found that the probability of remote distribution of cotton bollworm is more than 50%.

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.
