The present studies were conducted to determine the impact of mite population on germination in seeds of Maize and Mung from farmer's holdings of Tehsil Toba Tek Singh viz., Toba Tek Singh, Janiwala, Dabawala, Jalalpur, Dulum, Rajana, Bairianwala, Pairra and Chatiana. Mite population and germination were recorded at the initial stage of the experiment and after three months of storage. The results revealed highly significant differences between pest mite populations at different localities. In Maize maximum and minimum initial and final population of harmful mites were recorded from Rajana which was 3.33 and 6.66 respectively. In mung, maximum initial and final population of harmful mites was 2.33 and 5.33 respectively, from Rajana. Significant variations were recorded in initial and final germination percentage of the both commodities which ranged 86-91, 74.67-81 respectively, in maize and 85.83-91.83, 75.33-85.33 respectively in mung. Negative correlation was observed between harmful mite population and final germination percentage of maize and mung with correlation coefficients of -0.07 and -0.507 respectively.
