These awards reflect her deep commitment to entomological science, particularly in biological pest management, making her a role model for aspiring researchers in Iran and globally.
🔬 Research Focus
Dr. Hajar Pakyari’s research primarily revolves around biological pest control, with an emphasis on the predatory efficiency of thrips (Scolothrips longicornis) against spider mites (Tetranychus urticae) under varied environmental conditions. Her studies investigate factors such as temperature, photoperiod, and pesticide impacts on the life cycle, fecundity, and predatory behavior of beneficial arthropods. She has also contributed to understanding functional response models, development thresholds, and sublethal pesticide effects on beneficial mites and insects, aiming to enhance integrated pest management (IPM) programs. Additionally, Dr. Pakyari’s research extends to evaluating the influence of abiotic factors such as light wavelengths and heat stress on predator-prey dynamics. Her work bridges the gap between theoretical models and applied agricultural practices, ensuring ecological safety and sustainability. Through national and international collaborations, she continues to pioneer innovative approaches for pest management in crop protection systems.
