Being an industrial and food crop, the Tapioca (also called as Cassava) has a vast scope for area expansion and employment generation in Tamil Nadu. However, the recently invaded cassava mealybug, Phenacoccus manihoti threatens the livelihood of tapioca farmers. To tackle the current situation, ICAR-National Bureau of Agricultural Resources, Bengaluru has imported a parasitoid wasp, Anagyrus lopezi from IITA, Republic of Benin, West Africa as per Government of India guidelines during August 2021.
