The method of preparation of mass inoculum (MI) of native AM fungi was standardized following the principle of multiplying the nucleus inoculum (NI) of AMF (consortium of native soils) under partially sterilized in situ. Inoculation of arbuscular mycorrhizal fungi in root zone soils of different agricultural crops for which treatment no. 17 (Fenugreek –MaizeSorghum) host trap crops was found to be suitable for their mass multiplication.

Four different trap crop plants viz, napier grass, sudan grass, sorghum and bajra were assessed for their potential role as a trap crop in the management of spotted stem borer Chilo partellus (Swinhoe) on maize. Oviposition preference and larval survival tests were conducted in screen house under semi controlled conditions. Results revealed that napier grass was greatly preferred for oviposition over maize but the larval survivability was very poor.
