| Lauree magistrali | 2023 | An experimental analysis on the impact of plant water-stress and sulphur application on olfactory responses in Halyomorpha halys | An experimental analysis on the impact of plant water-stress and sulphur application on olfactory responses in Halyomorpha halys This thesis explores the responses of Halyomorpha halys, commonly known as the brown marmorated stink bug, to water-stress conditions and sulphur-based agrochemicals. The study aims to enhance sustainable pest management strategies by evaluating novel sustainable intensification approaches and their environmental impacts. Six different sulphur-based agrochemicals were tested and compared throughout the research. A range of experimental methodologies was employed to examine the effects of sulphur treatments and water stress on H. halys behavior. Two-choice tests conducted in controlled bug dorms presented the bugs with sulphur-treated and water-treated green beans and apple fruits (Golden Delicious). Behavioral cage trials utilized potted apple plants treated with sulphur-based agrochemicals alongside water-treated controls, creating a semi-natural environment for the bugs to interact with treated and control plants over a 24-hour period. These tests quantified repellence and attraction, revealing the insects' preferences for or aversions to sulphur-treated resources. Semi-field trials investigated how varying water stress levels impacted H. halys populations on potted apple plants. Plants subjected to different irrigation regimes, from well-watered to water-stressed conditions, were used to assess if water availability influenced plant vulnerability to H. halys infestations. Mortality tests were conducted to determine the effects of water stress on H. halys survival rates. | JAFRI, SYEDA TAHIRA FATIMA |
