A Comprehensive Review of Advances in Semiochemical Exploitation for Insect Pest Management

Abstract

In recent years, semiochemical-based pest management strategies have gained significant attention as they offer sustainable alternatives to conventional pesticides. Integrating semiochemicals into pest management strategies presents innovative approaches to addressing agricultural challenges. One promising method involves combining pheromones with entomopathogenic fungi, utilizing a "lure and infect" technique that attracts pests to fungal pathogens, enhancing control efficacy. Another advancement is the auto-dissemination approach, which promotes the spread of microbial pathogens within insect populations, effectively targeting pests like the fall armyworm. Additionally, the induction of plant defenses through "plant vaccination" by zoo phytophagous predators offers a novel way to enhance plant resistance against herbivores. Research into the production of insect pheromones in plants further supports sustainable pest management by disrupting pest mating behaviors. Electroantennography has emerged as a valuable tool for understanding insect olfaction, aiding in the identification of effective semiochemicals. The push-pull strategy employs plant semiochemicals to manipulate pest behavior, while pheromone dispensers provide efficient and long-lasting applications of these compounds. Collectively, these advancements highlight the potential of semiochemicals in revolutionizing pest management practices, aligning with the increasing demand for sustainable agricultural solutions. Continued research and innovation in these areas are crucial for optimizing the use of semiochemicals, ultimately contributing to more effective and environmentally friendly pest control methods.
