Popis:	A sequential decision plan, based on the Poisson distribution and providing for two infestation classes, was drawn up as an aid to management of the alfalfa weevil, Hypera postica (Gyll.), on first-growth alfalfa in Ontario. It is based on counts of the oviposition punctures in three-stem bouquets of alfalfa, and, in economic situations, will provide the grower with sufficient lead time to consider alternative action strategies. An appraisal of the plan under field conditions showed that it rated the infestation status of the weevil correctly in 56 of 60 cases. Sampling time averaged 35 man-min.
