Rapid assessment methods for stored maize cobs: weight losses due to insect pests.

 

A new method for the assessment of weight loss due to insect pests in stored maize cobs is described. The method involved 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 were 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.
