Erratic result of biological control agent is often associated with incomplete understanding of the ecological constraints of the biological system where they are placed. This truth is applicable for entomopathogenic fungi like Metarhizium anisopliae, Beauveria bassiana, Verticillium leccanii etc. Entomopathogenic fungi are inundatively introduced into the environment in absence of their host with a hope that they will persist and infect their target once the host immigrates into the treated area. Fungal persistence is important to consider for at least two reasons, first, it is desirable for the fungus to have a limited time span to minimize its possible harmful effects on non target species. On the other hand, the fungus should persist for as long as possible to reduce the need for continuous spraying. In an In vitro study we found M. anisopliae effective against Termite (Odontotermes obesus), Aphids (Aphis craccivora) at 1×106 spore /ml of water with a virulence of more than 78%. To study the persistence and viability of the fungus we applied M. anisopliae in an organic garden of Assam. Study showed the entomopathogen can survive in the air upto 12 months. This will definitely help in reducing the number of spray of the entomopathogen which ultimately reduce the cost of cultivation. Entomopathogenic fungi are considered to be an important bio-control tool for integrated pest management system. However, most of such fungi are host specific or species specific. M. anisopliae is effective against Termite (Odontotermes obesus), Aphids (Aphis craccivora) at 1×106 spore /ml of water with a virulence of more than 78%. The persistence and viability of M. anisopliae applied in an organic garden of Assam found that the entomopathogen can survive in the soil and air upto 12 months. This will definitely help in reducing the number of spray of the entomopathogen which ultimately reduce the cost of cultivation. The authors acknowledged Dr. C. Hazarika, Director of Post Graduate Studies, and Dr. G. N. Hazarika, Director of Research (Agriculture) and Dr. K. C. Puzari, Professor and Head Department of Plant Pathology, Assam Agricultural University, Jorhat-785013, Assam for their interest, support and suggestions during the period of study.
