Abstract

Life cycle and pathogenicity of Aphelenchoides swarupi were studied on U3 strain of Agaricus bisporus. The nematode took 5–6 days for completion of life cycle from J2 to adult at 30°C, and prolonged to 13–14 days at 15 ºC. Ten nematodes per plate as well as per kg compost in bags proved pathogenic. In plates, reproduction factor and population growth rate were minimum at one nema per plate but they decreased when inoculum level increased from 10 to 40. Yield reduction increased at all inoculum levels when inoculated at spawning compared to casing. Similarly, final nematode population was also higher when inoculation done at spawning compared to casing. Reproduction factor decreased with increase in inoculum level and higher population growth rate was achieved when nematode inoculation was done during casing compared to when done at spawning.
