Sažetak
Stink bugs are a growing problem in Croatia. They have caused significant economic damage to various fruit, vegetable, and field crops and it is reported that they utilize over 100 plant species as feeding or reproductive hosts. Southern green stink bug (Nezara viridula L., 1758.) and brown marmorated sting bug (Halyomorpha halys Stål, 1855.) are the dominant species from the Pentatomidae family in Croatia, while Ambrosia artemisiifolia L. is an invasive and aggressive weed present throughout the country. The aim of the study was to determine the toxicity of aqueous extract of A. artemisiifolia to adult individuals of N. viridula and H. halys under laboratory conditions. The study was conducted under laboratory conditions in September 2021 in three treatments: aqueous ragweed extract at a concentration of 10%, azadiractin (Ozoneem Trishul® -1%) and water as a control. Treatments were set in four replicates and a total of 240 adults stink bugs (120 N. viridula and 120 H. halys) were included in the experiment. All treatments showed mild toxicity. H. halys was more sensitive to the aqueous ragweed extract compared to N. viridula. Statistically significant differences in mortality between treatments were found in H. halys species 10–14 days after treatment with aqueous ragweed extract. Since no high efficacy of ambrosia extract has been found in the adult stage, research will continue on eggs and larvae that have a higher degree of sensitivity to aqueous and ethanolic extracts compared to the adult insect stage.
