以ASD7、IR36、粳籼89(JX89)、Mudgo四个抗褐飞虱水稻品种和感性品种TN1为材料,比较了褐飞虱和白背飞虱在这些品种上的行为反应。褐飞虱对抗性品种表现出明显的非嗜好性。褐飞虱自4h、白背飞虱自8h以后,各品种上的着虫量与TN1差异显著,而其它各品种上的虫量无明显差异(Mudgo除外)。白背飞虱选择各抗性品种的百分率明显大于褐飞虱(Mudgo除外);同一水稻品种上的稻飞虱数量无时间上的规律性。两种稻飞虱在抗性品种和TN1上的取食量差异显著。取食同一品种时,白背飞虱在IR36、JX89上的取食量大于褐飞虱,且相互间差异显著。两种稻飞虱在四个抗性品种上的取食痕数量明显多于TN1;两种飞虱在ASD7和JX89上的取食痕数量差异显著,白背飞虱的数量明显少于褐飞虱。在所有水稻品种上的取食痕数量与取食量呈明显的负相关关系。
The behavioral responses of BPH and BPPH were compared among four rice varieties resistant to BPH and TN1 with ASD7, IR36, JX89 and Mudgo. Nilaparvata lugens resistant varieties showed obvious non-preference. After 4 h of BPH and 8 h after BPPHE, there was a significant difference between TNW1 and TN1 in all the tested BPH species, except for Mudgo. The percentages of white-backed planthopper selected resistant varieties were significantly greater than that of the brown planthopper (except Mudgo); the number of planthopper on the same rice varieties had no regularity. There was significant difference between the two planthopper species on the resistant varieties and on TN1. Feeding on the same species, the whitebacked planthopper feeding on IR36, JX89 larger than the BPH, and the significant difference between each other. The number of feeding marks on the four planthopper species was significantly higher than that on TN1. The difference in number of feeding marks between two planthopper species on ASD7 and JX89 was significant, and the number of white-backed planthopper was significantly less than that of N. lugens. There was a significant negative correlation between the number of feeding marks and the amount of food taken on all rice varieties.
