Description Not Available
Increased globalization and trade have made India a
target for entry of many new alien insect pests. One
such unintentional recent introduction is the cassava
mealybug (CMB), Phenacoccus manihoti on cassava.
Monitoring on the occurrence and damage potential of
CMB on cassava was undertaken during 2020. Among
the places surveyed, maximum damage score (4–5)
and density of the mealybug (>1000/shoot tip) were
recorded in Salem and Namakkal districts of Tamil
Nadu and Thrissur district of Kerala. In the absence
of effective native natural enemies and other methods
of control, CMB might pose a major crisis to the cassava
industry in India. The prospects of its suppression by
classical biological control are quite vibrant and the
initiative to import the parasitoid wasp, Anagyrus lopezi
from Thailand and the Republic of Benin is already
being taken by ICAR-NBAIR, Bengaluru, India.
