在3个不同水稻品种上，研究江西南昌晚稻田内两索线虫对不同翅型和性别褐飞虱的寄生能力。结果表明：在同一水稻品种上，两索线虫对不同类型褐飞虱的寄生率之间存在显著差异，其寄生率的大小顺序为：短翅型雌虫>长翅型雌虫>短翅型雄虫>长翅型雄虫。其中，在短翅型雌虫体内，最高寄生率达45.16%；而在长翅型雄虫体内，最低寄生率仅为2.15%。在水稻品种株两优120上，两索线虫对短翅型雌虫的寄生数量达3头的占9.68%，对短翅型雌虫和长翅型雌虫寄生有2头的分别占6.45%和8.33%；在丰华占和合美（丰）上，对短翅型雌虫寄生数量最多为2头，寄生率分别为5.25%和4.35%；对不同类型褐飞虱的寄生数量为1头的均较高。可见，两索线虫对田间褐飞虱种群具有较强的寄生能力，可有效抑制褐飞虱的发生与危害。

The parasitic capacities of Amphimermis sp. to Nilaparavata lumens (Stal) were investigated into three kinds of rice varieties planted in Nanchang, Jiangxi Province. The results showed that the parasitic rates of different wing types and genders of N. lumens had significant difference at each rice variety, and that the order of the parasitic rates showed as follows:brachypterous females (BF)>macropterous females (MF)>brachypterous males (BM) > macropterous males (MM). Among them, the highest parasitic rate of BF was 45.16%, but the lowest parasitic rate of MM was only 2.15%. The parasitic rate of BF with 3 nematodes in body was 9.68%, and those of BF and MF with 2 nematodes were 6.45%and 8.33%, respectively, at the rice variety Zhuliangyou 120, but the parasitic rates of BF with 2 nematodes were 5.25%and 4.35%at the rice varieties Feng hua zhan and He mei zhan, respectively. Generally, the parasitic rate with just l nematode was higher than that with 2 or 3 nematodes. All the data above suggested that Amphimermis sp. had strong parasitic capacities, and could effectively inhibit the occurrence and damage of N. lumens in late rice fields.
