| 摘 要： | 本文对中华六索线虫的生物学及一些基本的生态学方面进行了研究。提出了六索线虫寄生粘虫的主动侵染的有关证据。研究结果还表明其群体在土壤中的栖息深度主要在20—40cm处,没有明显的季节性垂直迁移;土壤含水过多,偏酸偏碱以及盐渍化等对其存活都有明显的影响;对寄生率影响较明显的为侵染期的降雨日数和前一年线虫脱出高峰期的露日数。

| Abstract: | Some aspects on biology and ecology of the parasite nematode, Hexamermis cinensis, are described in this paper. It offers some evidences to confirm the initiatively infecting way. A great number of adults of H. cinensis dwell in 20-40cm of the soil, they hardly move in the soil in various seasons vertically. The relative moisture content of 60-80%, the value of pH of 6-7, and the salt content of soil solution of 0-0.1% are optimal to the survival and activity of the nematode. The rate of parasiting to the oriental armyworm is seriously influenced by the day number of raining of April and of dewing from 11-25, March of last year. |
