Detection of Insect Infestations in Cereals by Measurement of Uric Acid.

The levels of insect populations in food required to produce a measurable quantity of uric acid are discussed. The use of the uric acid content of a sample as an index of infestation or contamination was found not to be satisfactory. The test was not sufficiently sensitive. The high level of insect population generally necessary to produce a measurable quantity of uric acid (2 weeks for four adult Tribolium confusum per g. of food to produce a measurable amount of uric acid) seriously limits the value of the technique. The determination of the uric acid content of a sample would, however, be useful in producing evidence of a past infestation, but would be of no value in an attempt to predict the storage potential.
