Abstract

Coptotermesis 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. gestroithrough morphological characters and DNA barcoding. The possible infliction caused if invasive populations of

C. gestroienters India, in particular southern India, is discussed.

Abstract

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.

Abstract

For the first time, the tachinid fly, Exorista xanthaspis (Wiedemann, 1830) (Diptera: Tachinidae), was found to parasitize the larvae of fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) collected from maize fields in Karnataka, India. The field survey conducted during 2018-19 revealed the occurrence of E. xanthaspis on the larvae of S. frugiperda with the parasitism rate of 1.85 to 4.55% in maize fields. The identity of tachinid parasitoid was confirmed by amplifying Cytochrome Oxidase I gene (CO1-658 bp) and DNA.

Abstract

The occurrence of fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) in maize fields of Tirupati region, Andhra Pradesh is herewith reported. Field surveys in maize fields revealed that the rove beetle, Paederus fuscipes Curtis (Coleoptera: Staphylinidae) was found predating the larvae of fall armyworm and this is the first report of P. fuscipes on fall armyworm from India. The species identity of both fall armyworm and the rove beetle was confirmed through molecular studies by amplifying cytochrome oxidase I gene (CO1) and DNA barcoding.
