Members of the project team HRZZ-IP-2022-10-9643, senior assistant Dr. Qaiser Javed and assistant Luka Čotić (DOK-NPOO-2023-10-7422), took part in the European Researchers’ Night event held on September 25, 2026, in Split.

On this occasion, they presented selected research activities and project goals to visitors of all ages, focusing on innovative, sustainable methods for pest control in agriculture through the valorization of brewing industry by-products. Special emphasis was placed on introducing the public to the most important olive pest, the olive fruit fly (Bactrocera oleae Rossi), as well as other significant fruit flies from the Tephritidae family. Visitors had the opportunity to learn more about their biology, developmental stages, and modern, eco-friendly protection measures being developed within the framework of the project.

The event was an excellent opportunity to popularize science, bring advanced agronomic research closer to the general public, and educate visitors about the importance of sustainable agriculture and plant protection.

We are pleased to announce that our latest research paper titled:

“Electrophysiological, behavioral, and field responses of olive fruit fly to modified Brewer’s spent yeast formulations”

has been published in the prestigious Journal of Economic Entomology, as a collaborative effort between researchers from the Institute for Adriatic Crops and Karst Reclamation (Split, Croatia) and the University of California, Davis (UC Davis).

This study explores the valorization of recycled Brewer’s spent yeast (BSY) from breweries as a sustainable, protein-based attractant for the olive fruit fly (Bactrocera oleae), the primary economic pest of olives in the Mediterranean basin.

Dr. Elda Vitanović, Project Leader of BeerBy-4-OliveFly (HRZZ-IP-2022-10-9643), participated in the 32nd International Horticultural Congress (IHC2026), held from August 23 to 28, 2026, in Kyoto, Japan.

During the congress, she presented the latest research findings and results from the mentioned project within Symposium S15 (Plant Protection for Sustainable Horticulture).

This international gathering provided an excellent platform to share our scientific achievements, exchange knowledge with global experts, and highlight the project’s contribution to sustainable olive pest management.

As part of the continuous professional and scientific development of the BeerBy-4-OliveFly (IP-2022-10-9643) project research team, assistant Luka Čotić (DOK-NPOO-2023-10-7422) and senior assistant Dr. Qaiser Javed attended an international professional seminar organized by Restek Corporation.

The professional seminar, titled “Basics. Principles of GC” took place on Thursday, July 23, 2026, in collaboration with AnAs d.o.o. The lecture was delivered by distinguished international gas chromatography expert Mr. Jaap de Zeeuw (GC Specialist, Restek).

During the seminar, key fundamental topics in gas chromatography (GC) were covered:

• Fundamental Separation Principles in GC – Mechanisms of analyte interaction with stationary and mobile phases, as well as the effects of temperature and flow rate on chromatographic resolution.
• Optimization of Analysis Parameters – Key factors for achieving high reproducibility and sensitivity in quantitative and qualitative analysis.
• Good Laboratory Practices and Maintenance – Guidelines for proper sample preparation, column selection, and preventing common pitfalls in chromatographic workflows.

Upon successful completion of the seminar, assistant Luka Čotić and senior assistant Dr. Qaiser Javed were awarded official Certificates of Completion.

This continuous training and reinforcement of core gas chromatography principles further ensures high accuracy and reliability during analytical measurements conducted within the project research.

Congratulations to Luka and Qaiser on completing the training and earning their certificates!
