摘要: 研究了不同地理种群褐飞虱对水稻抗性品种、若虫高密度、高温、饥饿和杀虫剂等逆境条件的抗性.结果表明,广西和云南种群褐飞虱对抗虫品种的适应性比浙江种群强而广,浙江种群只能适应抗虫品种IR26而广西和云南种群则还能适应抗性更高的ASD7和Rathu Heenati.广西和云南种群较能适应高密度环境,而浙江种群的适应性较差,其雌虫短翅率与若虫密度呈显著负相关.虽然广西和云南种群对高温的忍受性比浙江种群的强但对饥饿的耐性则明显较弱.对氧化乐果的耐药性浙江种群比广西种群略强,说明不同地理种群褐飞虱对逆境条件的抗性差异主要是由于他们长期适应了各自所处的特定生存环境引起的.

Abstract: The populations of brown planthopper(BPH), Nilaparvata lugens,were collected from Zhejiang,Guangxi and Yunnan provinces to study their tolerance to various adverse environmental stresses.The results indicated that all of these three populations could adapt to the rice variety IR26 bearing resistant gene 1 (Bph1), and Guangxi and Yunnan populations could successfully infest rice varieties ASD7 bearing bpH2 and Rathu Heenati bearing Bph3,implying that these two populations had a higher adaptability to resistant rice varieties. The significantly negative relationship between female brachypterous rate and nymphal density in Zhejiang population showed a lower tolerance to high nymphal density of Zhejiang population than that of Guangxi and Yunnan populations. A higher resistance to high temperature and a lower tolerance to starvation were obviously found in Guangxi and Yunnan populations. The resistance to insecticide (Omethoate) of Zhejiang population was little higher than that of Guangxi population. It was suggested that the tolerance of different geographic populations of BPH to various adverse environmental stresses be closely related to their habitat characteristics.
