Abstract

A sequential sampling plan was developed for treatment decisions on cashew thrips in Thailand from 1993-94. The data was drawn from cashew shoots or inflorescences grown at Nakhon Pathom and Ubon Ratchathani Provinces by using the tray beat method. The negative binomial distribution with a common k value of 0.7569 was used to devise a sequential sampling method in order to classify thrips populations as light and treatment not recommended versus outbreak with insecticide treatment required. Operating characteristic and average sample number were also calculated.
