Brown marmorated stink bugs (Halyomorpha halys) (Hemiptera: Pentatomidae) is a harmful insect that entered Romania for several years. Its polyphagous is accentuated and in the continuous expansion of the host plants, whether agricultural or horticultural and deciduous forest. Through the present work we have proposed to see what is the current state of the pest in 5 OPs in Timis County related to density, updated range of host plants but also to try to keep populations under control so as to avoid damage. So, for 4 years (2020-2023) from May to October we made observations in various types of areas (field crops, private gardens, parks and fruit orchards). As results, we found high and medium frequency in private gardens with mixed plants but also in orchards, while in field crops, they had a lower frequency. In August, the most specimens were seen. After testing 2 products (a classic insecticide and an bio-insecticide), the classic one proved to be more effective, but taking into account the effects of pollution environment, it is recommended to apply the bio-insecticide first, however both must be used to maximize effectiveness.
