Abstract

This paper describes a new method for the assessment of weight loss due to insect pests in stored maize cobs. The method involves scoring each cob in the sample on a visual damage scale and then using a simple equation to estimate overall sample weight loss. The coefficients in the equation are determined in advance of field work by calibrating the visual scale against a laboratory loss assessment technique. The visual scale method was found to be rapid, simple and had many advantages for on-farm work. Precision of the results was shown to be similar to that of existing weight loss assessment methods.
