Abstract

Feeding mice on infested wheat flour with three tenebroinid in­sect species, demonstrated strong toxic effect on the animals. Both liv­er and lungs of mice seem to be more sensitive than spleen. Morphologi­cal and histopathological studies made on these organs indicated obvious toxic symptoms probably due to the defensive secretion of ben­zoquinone compounds, discharged by tenebroinid insects. These com­pounds might have a carcinogenic effect on certain organs.
