A moderate level of resistance to the two spotted spider mite was found among the lines tested. The lines with the lowest average damage ratings over a 3-year period were NC accessions 17347, 17367,469, 343, and 302. The lowest damage rating was 17.5% for 17347 compared with 36.1% for ‘Florigant’ and 52.5% for ‘NC-Fla 14,’ the two susceptible standards. Spider mite populations during 1975 and 1976 were significantly related to percent foliage damage, fitting the exponential nonlinear relationship of D = (1 – e−0.0033N)100, where D = percent foliage damage and N = number of two spotted spider mites.}, number={6}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={JOHNSON, DR and CAMPBELL, WV and WYNNE, JC}, year={1982}, pages={1045–1047} }

The 10 domestic and wild species of peanuts were selected from previous screening tests for resistance to feeding damage from T. urticae . Mites feeding on wild species PI 262286 and 262840 had greatly reduced egg production when compared to the domestic line NC 5. Mites oviposited 8.5 eggs/female on NC 5 in 48 h and only 0.8 eggs/female on PI 262286. The domestic lines NC accessions 302, 827. and GK-53 exhibited a moderate reduction in mite egg production when compared to NC 5. Adults females of T. urticae exhibited a high level non-preference for feeding on the wild species PI 262286 and 262840. No significant degree of non-preference for feeding was found among the domestic lines.}, number={4}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={JOHNSON, DR and CAMPBELL, WV and WYNNE, JC}, year={1980}, pages={575–576} }
