| Abstract: | Mixed populations of peanut white grubs display an aggregated pattern of distribution. Based on a known regression relationship of m-m a suitable sampling model for different population density levels and field trial methods for evaluating the effectiveness of control methods on peanut white grubs are proposed. The performance of two such methods were compared. |

| Keywords: | peanut white grubs aggregation pattern sampling number effectiveness of control evaluation methods |
