One hundred and fifty groundnut breeding lines from North Carolina State university were evaluated for resistances to leafminer, thrips, leafhopper and yellow spot virus under natural field infestations at Khon Kaen during July-October 1987. The experiment was conducted using a randomized complete block design with four replications. Several entries exhibited multiple insect resistances, others were only resistant to specific insects. Yields of 13 entries from ICRISAT and 3 from Insect Germplasm Test were not significantly different from those of Tainan 9.
