Abstract

The relationship between population density of sunn pest and kernel damage percentage, especially in natural farmers’ situations, determines a criterion for the economic injury level (EIL). For this purpose three wheat farms, cultivated with either Sardari or Azar2 varieties were selected in each of Lorestan and West Azarbaijan provinces. Population densities of nymphs and new adults were sampled both by quadrat and sweeping net sampling methods (each using twenty-five 20-squer-meter plots) during the last month of wheat growth. Then, at harvesting 10 wheat spikes were randomly taken off from each plot to determine kernel damage percentage. The relationship between population density and kernel damage percentage in each plot was determined, using correlation and regression analyses. Linear and nonlinear models were also fitted using TableCurve 2D software. As a result, exponential models were properly fitted for Sardari variety in both quadrat and sweeping net methods, respectively, whereas power and exponential models were well matched with Azar2 variety for the respective methods. Based on the models prediction, mean population densities that could cause 2 percent kernel damage in Sardari and Azar 2 varieties were 3.25 and 2.88 for quadrat and 4.3 and 2.82 for sweep net, respectively. Moreover, the EILs of the nymphs and new adults for different kernel damaged levels were discussed.
