Extract

The objective of the present work was to determine the statistical distribution of midge damage between heads of wheat as a guide to estimating the number of wheat heads that would constitute a reliable sample in estimating losses caused by this pest. A brief account of the history and geographical distribution of the wheat midge in Manitoba has been given by Barker (1984).
