Abstract: Estimates of the loss of tea crop due to red spider mite have been derived using three different methods: (1) least squares, (2) Wald's method, and (3) Bartlett's method, for the case when the relationship between yield and infestation is linear. The results have been illustrated with the help of data collected from sample surveys on pests and diseases of the crop conducted in the Dooars, a region of north‐east India.
