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.Keywords

Coptotermes is one of the most widespread subterranean termite genus of economic significance with few species considered as truly invasive. Coptotermes gestroi (Wasmann) is also known to be invasive and has taxonomic confusion on its correct identity. Originally described from Myanmar, it is considered to occur in North East India and Thailand. However, it is found to cause serious economic losses in some Asian countries, Brazil, the Caribbean islands and peninsular Florida, USA. In the present study, the insect specimens which were recovered from imported wooden packaging material of a consignment at Goa, India, received from Harrisonburg, Virginia, USA have been reported. The termite species received was identified as C. gestroi through morphological characters and DNA barcoding. The possible infliction caused if invasive populations of C. gestroi enters India, in particular southern India, is discussed.Keywords
