Resumen
- This study was conducted during November and September 2025 on stored grain insects (wheat) to determine the effect of phosphine gas (PH3) on these insects. The results obtained after fumigation showed the death of all insects subjected to the experiment (100%). Approximately one month later, the infestation returned, with the rust beetle and grain borer observed, but their presence was very low, ranging between 4% and 8%. The results confirm that this gas is effective and can be used to control stored grain insects.
