Professor Mitko Subchev (1945-2023).

The article in Acta Zoologica Bulgarica from December 2024 honors the late Professor Mitko Subchev, a renowned Bulgarian zoologist recognized for his research in insect chemical ecology, particularly focusing on crayfish worms and insect chemical communication, including pheromones. Subchev's extensive publications and collaborations with international researchers have greatly advanced the field of zoology. The document details a comprehensive list of sex attractants for various Lepidoptera species, such as moths and butterflies, crucial for monitoring and studying their behavior. Professor Subchev's research, along with his colleagues, has significantly enhanced the understanding of pheromone communication systems in these insects, identifying specific compounds and ratios effective for attracting them for research purposes.
