Popis: In developing its quarantine policy for the importation of fruit-fly host material, New Zealand has used the concept of a maximum pest limit. An equation which links the maximum permissible numbers of fruit flies with lot size (N), mean number of mature fruit fly larvae per infested fruit (μ), proportion of infested fruit (p), and treatment efficacy (μ) has been suggested. We discuss the research which is needed to obtain accurate measurements of the parameters in the model. Decisions based on these parameters support the development of a quarantine policy that can be justified scientifically. Methods for collection of biological data to determine μ and p are detailed. It is suggested that efficacy trials to measure φ should be based on dose/mortality assessments. Experimental techniques used in efficacy trials should focus on assessment of variability and determination of confidence limits. Application of the maximum pest limit equation is discussed.
