| 摘 要： | 1982～1984年对寄生稻飞虱的多索线虫在浙江省宁波地区的分布进行了调查。结果表明:平原、丘陵、沿海以至海拔800米山区稻田都有多索线虫的存在。其宿主有褐稻虱等6种,寄生率28.6～88.9％,是稻飞虱的重要寄生性天敌。多索线虫的适宜生境为:一般稻田有机质含量3％以上,pH 5.5～6.5,质地中粘土或轻粘土,田间湿度较高。

| Abstract: | Field occurrence of mermithids (Agamermis sp.) infesting rice hoppers was investigated during 1982-1984 in Ningpo prefecture. The mermithid distributes in different types of paddy fields in plains near or away from the sea shore, hillysides, and mountainous regiona with various densities. Of the aix host species, four important pests, Nilaparvata lugens. Laodelphax atriatella and Sogatella furcifera accounted for 88.9% of the nematode parasitization. Paddy fields with PH 5.5 to 6.5 and high humus content were found to be favorable to Aganermis sp. |
