Special Issue Information

Dear Colleagues,

Insects pose a significant threat to stored products. Currently, insect control at the post-harvest stages of agricultural products is primarily based on the use of contact insecticides and fumigants, such as phosphine, which are directly applied either to the product or to the storage and processing facility. However, the continuous use of these insecticides has led to the development of resistance by several major insect species, often rendering chemical control ineffective. Furthermore, many traditional substances are no longer in use due to their high toxicity to mammals and extreme threat to the environment.

This Special Issue aims to highlight the development, application, and evaluation of integrated pest management (IPM) strategies in food processing and storage facilities. It will focus on innovative approaches and technologies that offer sustainable and effective solutions for managing stored-product pests.

For this Special Issue, we welcome all types of articles, including original research articles, short communications, and reviews. We encourage studies that offer practical, high-precision, and innovative solutions with promising applications in the field of pest management.

Phosphine is a widely utilized fumigant insecticide in stored-product facilities; however, its excessive application and improper usage have contributed to the emergence of resistance in insect populations. Although phosphine resistance is globally recognized, limited studies address its effects across different developmental stages. This research investigates the efficacy of phosphine on the eggs of major stored-product pests, including Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae), Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae), Tribolium castaneum, and T. confusum (Coleoptera: Tenebrionidae), focusing on strains with varying levels of phosphine susceptibility. Egg hatching rates were analyzed following exposure to phosphine concentrations ranging from 50 to 1000 ppm for durations of 1 to 7 days. Predictive models were constructed to correlate phosphine concentration and exposure time, facilitating the determination of optimal pest control strategies. The findings reveal significant differences in efficacy among species and strains, with eggs from susceptible strains experiencing complete hatch failure at 50 ppm, while resistant strains showed higher tolerance. Lethal time (LT50 and LT99) values were determined, with LT99 ranging from 6.91 to 12.95 days at 50 ppm, highlighting species-specific and age-related differences in phosphine susceptibility. Lethal concentration (LC50 and LC99) values could only be estimated for T. castaneum, with LC99 for 1-day-old eggs ranging from 773.67 ppm to 923.03 ppm after 2.5 days of exposure. Furthermore, egg age influenced susceptibility, with 2-day-old eggs exhibiting greater mortality compared to 1-day-old eggs. This study underscores the critical role of phosphine concentration, exposure duration, and developmental stage in resistance management, providing valuable insights for enhancing fumigation protocols and improving the control of stored-product pests.
