The relationship between different levels of internal wheat infestation with three stages of the lesser grain borer (larvae, pupae, and newly eclosed adults) and the number of insect fragments produced in flour was studied. Insect fragments counts were determined by the standard flotation method and by near-infrared spectroscopy. Both methods correlated well with the number of insect fragments present in flour.
