DNA barcoding employing a 658 bp fragment of 5′ region of the mitochondrial cytochrome oxidase I (CO-I) gene is an efficient and accurate method for identification of aphid species (including cryptic species), an approach that potentially could play an important role in formulating viable pest management strategies, more especially biocontrol.
DNA Barcoding and Elucidation of Cryptic Diversity in Thrips (Thysanoptera)

The feasibility of hosting an independent integrated taxonomy library for thrips is proposed and it is indicated that it can serve as an effective system for species identification, this approach could potentially play a key role in formulating effective insect pest management strategies.
Biology of Bactrocera (Zeugodacus) tau (Walker) (Diptera: Tephritidae)
The biology of the fruit fly Bactrocera tau, an important horticultural pest, was studied under laboratory conditions at 25°C and 60–70% relative humidity on Cucurbita maxima and the life cycle from egg to adult was completed in 14.2 ± 1.47 days.
Faunistic, ecological, biogeographical and phylogenetic aspects of Coleoptera as gall-inducers and associates in plant galls in the Orient and eastern Palearctic
- Vilayanoor Venkataraman Ramamurthy
- 1 January 2007
An attempt has been made to clarify the faunistics of coleopteran gall-inducers, interactions of Coleoptera with other gall-inducing arthropods, and their usefulness in terms of biological control and evolution, concentrating on select species from the Orient and eastern Palearctic fauna.

It is shown that the DNA barcode and species-specific markers will aid the identification of mirids in India and will stand as a decisive tool in formulating integrated pest management (IPM) strategy, quick identification of invasive and cryptic species, haplotypes, biotypes, and other factors, if any.

- 1 September 2012
Formation of flanges, salivary sheath and penetration pathway observed along with probing and penetration of the stylets intracellularly up to the phloem cells, as illustrated herein, are the addition to the existing knowledge on the structural details of the mouthparts and the feeding behavior thereupon.
Record of new parasitoids on mealy bug, Phenacoccus solenopsis.
Reconstructing the macroevolutionary patterns of aphids (Hemiptera: Aphididae) using nuclear and mitochondrial DNA sequences
Bionomics of Odoiporus longicollis Olivier (Coleoptera: Rhynchophoridae) on banana plant (Musa paradisica).
Black and reddish brown adults were recorded from the splitted pseudostems of the damaged banana plants and colour difference represents a phenomenon of non sex limited variation in conspecific sympatric phena of the pest.
