Guillermo Rehermann Del Rio
Guillermo is a PhD student in Biology - Chemical Ecology, fascinated in understanding how chemical substances produced by organisms convey information that mediates and modulates their interactions with other living creatures.


Animals use visual, tactile and chemiosensory cues to recognize food sources and conespecifics. Interestingly, insects rely to a high extent on the sense of smell to assess food quality and/or potential mates. Investigation of the insect olfactory system and other sensory signals provides a better understanding of how chemical cues (semio-chemicals) drive insect interactions with other living organisms. Specifically, I study emission and perception of signals in pest insects and their multitrophic interactions with plants and microbes.  Investigating their chemical ecology generates opportunities to develop novel and safe tools for sustainable pest management.  


I participate in the following courses: 
-Project based research training (Code: LB0066) (Dept. of Biosystems and Technology - Dept. Plant Protection Biology, SLU) (2019)

-Master course in Insect Chemical Ecology (Code: BI0914) (Dept.Plant Protection Biology, SLU) (2019).

-Master course in Horticultural Systems and Future Challenges (Dept. Plant Protection Biology, SLU) (Code: Bl1309) (2018, 2019).

Furthermore, I am currently involved as mentor for students doing their ‘Gymnasiearbete’ as well as for PROA-students at SLU.


My research concerns odour signals that mediate communication between insects, and between insects, micro-organisms, and plants. My current project focuses on the spoted wing drosophila pest (SWD), Drosophila suzukii. Like other drosophilids, SWD is closely associated with microorganisms. The overall goal is to understand the relevance of microbial signals in the ecology and behavior of SWD flies with emphasis on the role of yeast and bacterial odors in sexual, food- and host-finding behavior. The main goal is that the integration of biological knowledge facilitates the development of sustainable tools to disrupt host-insect interactions in pest insects.
My expertise is on Chemical Ecology, with an emphasis on sensory physiology, behavioral assays, and field experiments.
