The growing demand for food due to a global population increase has made the use of pesticides in agriculture unavoidable despite their various harmful side effects. Driven by stricter legislation, nations are now compelled to find alternatives. This situation led to accelerated research around the world, focusing on developing new chemistries to enhance the environmental safety of pesticides. In recent years, bioinspired strategies of pest control have emerged as alternatives to the development of new synthetic pesticides. In order to design innovative eco-friendly pest management techniques, a thorough understanding of naturally existing physical and chemical defences in plants is needed. Building upon this knowledge, material science provides innovative strategies for designing physical barriers, biomimetic adhesives, and targeted delivery systems that go beyond traditional chemical approaches. This tutorial review explores the intricate relationships between plants and insects, focusing on natural defence mechanisms such as plant cuticles, trichomes, and thigmonasty. We also review advances in synthetic pesticide use, including enhanced adhesion and controlled release formulations. In addition, we delve into advances in other integrated pest management domains, discussing the potential of bioinspired surfaces and biological control methods. This overview aims to foster comprehensive understanding and interdisciplinary approaches, highlighting the pivotal role of material science in improving sustainable pest control for the future.
