Evolution the current situation of green stink bugs populations in agricultural areas of timis county and effective control strategies

Green stink bugs (as polyphagous pest) are still active in agroecosystems in Romania producing negative effects in various types of agricultural and horticultural areas. In this paper, we focused on the population capacity of the pest in 8 localities belonging to Timis County, each representing a type of area, but also on the monthly dynamics during 5 months (June-October) from 2019-2022. We also focused on testing both chemical and non-polluting control products currently used by farmers and gardeners in the western part of the country. From the ones analysed, we found that in all the monitored localities the pest was present at varying levels from low to high. Regarding the monthly dynamics, the most specimens were observed in August and September, with a maximum recorded in 2020 followed by 2021. The most effective control strategy involves a chemical product applied individually, i.e Karate Zeon (lambda -cihalotrin) but also the Laser 240 SC (spinosad) product, 1-2 applications. Their combination is essential in keeping harmful populations under control.
