Abstract:Sequential sampling. in which decisions depend upon the accumulated results of a series of observations, leads to considerable saving of time and effort. A sequential plan, based on the negative binomial distribution and providing for 2 infestation classes, was drawn up for use in control of the cabbage looper, Trichoplusia ni (Hübner) , on cauliflower. An appraisal of the plan under field conditions showed that it reduced the sampling time by two-thirds while rating the infestation correctly in 82 of 84 cases. With the 2 discrepancies, population means lay between the limits set for the infestation classes.
