Himadri Kaushik, Pranab Dutta, and Jatin Kalita receive Stanford Research Award- 2015 in Integrated Pest Management. 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,
