Research Interests
Developing innovative pest monitoring and control methods based on the understanding of natural processes, such as the chemical composition and behavioral effects of kairomone/pheromone attractants.
Dissertation Summary
The research focuses on newly introduced and spreading European insect pests, particularly Otiorhynchus sp., with an emphasis on species O. armadillo and O. salicicola. These polyphagous beetles damage a wide range of shrubs, trees, ornamental, and garden plants, with significant harm observed in red raspberries and strawberries. The pests affect both underground and aboveground plant parts, with larvae feeding on roots and adults consuming leaves and flowers.
As conventional pesticide use and its intensification negatively impact both the environment and human health, there is a critical need for environmentally friendly pest monitoring and control methods, which are currently underdeveloped. This study aims to address this gap by investigating insect pests.
The research will involve recording olfactory and behavioral responses of pests to volatile compounds emitted by host plants and insects. For the first time, electrophysiologically active compounds of O. armadillo and O. salicicola will be identified. Laboratory studies will select kairomones (from plants) and pheromones (from insects) that are attractive to these species. The selected compounds will be tested under field conditions, and recommendations will be developed for using the most effective mixture in insect traps for monitoring purposes.
The dissertation is expected to yield significant findings for both fundamental and applied sciences. Additionally, it will investigate the distribution of O. armadillo and O. salicicola in Lithuania.
