摘要： 比较了我国南宁、越南河内、河静、顺化、胡志明市、九龙江6个褐飞虱地理种群的差异.结果表明：南宁、河内、河静、顺化的褐飞虱种群能致害含Bph1和bph2抗虫基因的水稻品种，而越南胡志明市、九龙江褐飞虱种群的致害能力更强，对含Bph1、bph2、Bph3、bph4抗虫基因的水稻品种均表现为致害或强致害；南宁、河内、河静、顺化褐飞虱若虫在水稻品种TN1、Mudgo、ASD7上的存活率均在52%以上，在Rathu Heenati、Babawee、Ptb33上的存活率均低于44%；胡志明市、九龙江褐飞虱若虫除了在Rathu Heenati上的存活率低于50%外，在其他品种上的存活率都在50%以上.南宁、河内、顺化褐飞虱若虫在TN1、Mudgo、ASD7上的发育历期显著短于在Rathu Heenati、Babawee、Ptb33上的发育历期；河静褐飞虱若虫在TN1、Mudgo、ASD7上的发育历期与在Rathu Heenati、Ptb33上的发育历期差异不显著.胡志明市褐飞虱若虫在TN1、ASD7上的发育历期显著短于在Rathu Heenati、Babawee、Ptb33上的发育历期；九龙江褐飞虱若虫在TN1、Mudgo、ASD7、Rathu Heenati、Babawee、Ptb33上的发育历期差异不显著.选择性试验表明，接虫192 h后，南宁、河内褐飞虱若虫在Rathu Heenati、Babawee、Ptb33上的虫口密度显著低于在TN1、Mudgo和ASD7上的虫口密度；河静褐飞虱若虫在Babawee上的虫口密度显著低于在TN1、Mudgo上的虫口密度；顺化、胡志明市褐飞虱若虫在Babawee上的虫口密度显著低于在TN1、Mudgo、ASD7、Rathu Heenati上的虫口密度；九龙江褐飞虱若虫在Babawee、Ptb33上的虫口密度显著低于在TN1、ASD7上的虫口密度.本研究发现,我国南宁褐飞虱田间种群与越南河内、顺化、河静(属于越南中部及北部地区)的褐飞虱田间种群致害性相似，从而为“越南中北部是褐飞虱迁入我国的虫源地”提供了新的证据.

Abstract: A comparison was made on the differences of the geographical populations of brown planthopper (BPH), Nilaparvata lugens (St-l), collected from Nanning of South China and from Ha Noi, Ha Tinh, Hue, TP. Ho Chi Minh, and Song Cuu Long of Vietnam. The BPH populations from Nanning, Ha Noi, Ha Tinh and Hue could damage the rice varieties with Bph1 and bph2 genes, whereas the BPH populations from TP. Ho Chi Minh and Song Cuu Long showed stronger virulence to the rice varieties with Bph1, bph2, Bph3 and bph4 genes than the other populations. The survival rates of the nymphs from Nanning, Ha Noi, Ha Tinh and Hue populations on the rice varieties TN1, Mudgo and ASD7 were all above 52%, but those on the rice varieties Rathu Heenati, Babawee and Ptb33 were below 44%. The nymphs of the BPH populations from TP. Ho Chi Minh and Song Cuu Long on the TN1, Mudgo, ASD7, Babawee and Ptb33 had a survival rate of above 50%, but those on Rathu Heenati had a survival rate of below 50%. The nymphal development durations of the BPH populations from Nanning, Ha Noi and Hue were significantly shorter on TN1, Mudgo and ASD7 than on Rathu Heenati, Babawee and Ptb33, but for the BPH population from Ha Tinh, the nymphal development duration on TN1, Mudgo and ASD7, and on Rathu Heenati and Ptb33 had no significant difference. The nymphal development durations of the BPH population from TP. Ho Chi Minh on TN1 and ASD7 were significantly shorter than those on Rathu Heenati, Babawee and Ptb33, but for the BPH population from Song Cuu Long, the nymphal development durations on TN1, Mudgo, ASD7, Rathu Heenati, Babawee and Ptb33 had no significant difference. After infested for 192 h, the nymph density of the BPH populations from Nanning and Ha Noi was significantly lower on Rathu Heenati, Babawee and Ptb33 than on TN1, Mudgo and ASD7, that of the BPH populations from Ha Tinh was significantly lower on Babawee than on TN1, Mudgo, the BPH populations from Hue and TP. Ho Chi Minh had a significantly lower nymph density on Babawee than on TN1, Mudgo, ASD7 and Rathu Heenati, and the BPH population from Song Cuu Long had a significantly lower nymph density on Babawee and Ptb33 than on TN1 and ASD7. The virulence of the BPH population from Nanning was similar with that of the BPH populations from central and northern Vietnam, which was a new proof that the BPH in South China was migrated from the central and northern parts of Vietnam.
