Figure 1 Preference of nymphs to settle on rice varieties. The bars followed by the same letter each time are not significantly different (DMRT3 = 0.05). 2, 6, and significan significant 33, RH and 2 yd The settling of nymphs on rice varieties was not significantly d There were different results for the adult (Figure 2). The number o ifferent in every observation (Figure 1). f adults observed in each rice varieties at hours after infestation (HAI) were not ifferent (P> 0.05). After 24 hours, adults y settled on TN1 compared to Inpari 13, Inpari PTB33 (F= 5.52; P< 0.001). Since 48 to 72 HAI, number of adults in resistant varieties significantly less than 7 TN (F= 11.57; P< 0.001). Among modern rice varieties, the lowest number of adults was found in Inpari 13 t nan Inpari 31 and Inpari 33. The result of settling test showed that nymphs were spread equally in each variety.
