Abstract: Phosphine, a primary fumigant in stored product facilities, faces decreased
susceptibility issues globally, yet its impact across insect life stages is underexplored. Our study assessed phosphine’s efficacy on eggs from various stored product pests. Exposure to
concentrations (50-1000 ppm) for durations (2.5-7 days) revealed varying susceptibility based on species, age, and exposure. Susceptible strains showed no hatchings at 50 ppm and complete mortality at 200 ppm for over 5 days. Contrasting susceptibility between 1-day-old and 2-dayold eggs was evident. Understanding phosphine’s interaction with exposure duration enhances pest management strategies in stored product facilities.
