Prof. Dr. Sándor Keszthelyi - MATE Research
Overview
Dr. Sándor Keszthelyi serves as an agricultural entomologist and is leading the Division of Applied Forage Crop Cultivation in Kaposvár. Specializing in plant protection, agro-zoology, and arable farming, his research focuses on ecology, damage scouting, and protective strategies against arthropod pests in crops like maize, cereals, and oilseed rape. His work involves studying population dynamics, utilizing advanced imaging techniques, and exploring environmentally sustainable protection methods for stored product pests. Additionally, he conducts meta-analytical examinations of invasive agricultural pests, including the cotton bollworm, western corn rootworm, ragweed leaf beetle, and European corn borer.

Projects
Biological investigations of agricultural pests with the help of non-invasive techniques
There are many harmful and yield-reducing arthropod pests that live in plant tissues and cause almost imperceptible damage, e.g. Ostrinia nubilalis Hbn., Cydia pomonella L., Acanthoscelides obtectus Say. Their ecological and biological properties are quite well known. The process leading to damage is difficult to follow with traditional imaging techniques.
The results provided additional biological and ecological information about the hidden lifestyle of cryptic insects. Therefore, it can greatly contribute to the realization of the criteria of integrated plant protection in practical plant protection.
