3.  The global/regional climatic changes and local physiographic changes are anthropogenic
 These changes have immense impacts on health of various ecosystems and the
biodiversity, including insects, supported by them.
 The Impact Assessment, is difficult, costly, time consuming and may involve several
methods. One of these methods is called, bioassessment
 Major focus of Bioassessment studies are specific mega-diverse biological groups, the
insects being one of them.
 Among insects, the Lepidoptera is a known flagship group for bioassessment, as shows
good species diversity (with over 1,60,000 described species ;Kristensen, et.al.,2007),
intraspecific genetic divergence and wide geographical distribution.
 Lepidopterans are recognized as moths, butterflies and skippers. Many of these are
described as biodiversity indicators, ecological indicators, and substantial number of
species are pests of agricultural crops, horticultural trees and forest plants. These features
further enhance their bioassessment potentials.
 Bioassessment involves sampling of Lepidopterans for making observations such as
species extinction, changed distributional limits and population sizes, and genetic
divergence within species. For this rapid identifications of collected samples is required.
 Rapid identifications and assessment of genetic divergence within species involve the
mitochondrial CO1 gene based DNA barcoding (Hajibabaei, et. al., 2004, 2006, Desalle,
2006). Additional mitochondrial genes such as nad1 ,nad4 ,nad5 ,nad6 ,COII, and 16s
rRNA are employed for assessing intraspecific variations.
 Global barcode database of the order Lepidoptera is available on BOLDSystems
(http://www.boldsystems.org). It is regularly updated by submissions from all parts of
the world. At the moment, BOLDSystems has 74,947 species with barcodes and 6, 70,267

4.  To expose zoologists and Environmentalists to
methodology of bioassessment of impacts of
climatic and physiographic changes.
 To highlight Lepidoptera as one of the flagship
group for such impact studies.
 To throw light on DNA Barcoding as a chief tool
to be adopted for rapid bioassessment studies.
 To highlight mitochondrial genes – CO1, COII,
nad1, nad4, nad5, nad6 and 16s rRNA, as the
chief tools for diagnosis and delimitation of
species, and to assess genetic divergence within
species.

5.  Order Lepidoptera of Class Insecta comprise the material for the present studies.
 Butterflies and moths will be collected by following their collection protocols; and two
right legs will be excised from each sample and preserved in ethyl alcohol, labeled and
stored in refrigerator for DNA Barcoding.
 DNA Barcoding is based on Mid region of the mitochondrial COI gene which is
amplified through PCR by employing:
- Universal Insect Specific Primers (Hebert, et. al., 2003)
LCO : 5’-GGTCAACAAATCATAAAGATATTGG-3’, and
HCO : 5’-TAAACTTCAGGGTGACCAAAAAATCA-3’
- Lepidoptera Specific Primers (Hajibabaei, et. al., 2006)
LepF : 5-ATTCAACCAATCATAAAGATATTGG-3 , and
LepR: (5 -TAAACTTCTGGATGTCCAAAAAATCA-3 , or
Enh_Lep R1: 5 -CTCCWCCAGCAGGATCAAAA-3’
 Intraspecific variations are studied by additional mitochondrial genes – nad1 (Miller,
et.al., 2009), nad4 (Gomez, et.al.,2009, Liu, et. al., 2010 ), nad5 (Meraner, et.al., 2008), nad6
(Silva-Brandao, et. al., 2011), COII (Liu, et. al., 1992), and 16s rRNA (Raffiudin, et. al.,
2011); and for their amplification, specific primers are used according to respective
protocols.
 The sequences for the identified and described species are submitted along with
collateral information including photograph to web-repositories (www.BOLDSystems.org;
www.ncbi.nih.gov).These add into already existing database.
 Later, submission of sequences of unknown specimens helps in immediate arrival at the
conclusion whether species is already known or novel to science and how much genetic
closeness it has with different species.
 % divergence or genetic distances are estimated through multiple sequence alignment in
MEGA version 5 software to delimit species, and to assess population variations within
species.

7.  Till majority Lepidopteran species are barcoded and
submitted on global database, rapid identification of
Lepidopterans vis-à-vis prompt bioassessment of impacts
of climatic changes and physiographic changes is not
possible.
 There is an urgent need for developing a comprehensive
DNA barcode library for the Lepidopterans.
 As the rate of submissions is picking up pace and good
amount of funds are being diverted by states to DNA
Barcoding, rapid bioassessment of impacts on
Lepidoptera will soon become reality. This will help in its
effective conservation.

8.  Thanks are due to Principal SGGS College, Chandigarh for allowing
the author to attend and present this poster in the present
conference.
 Sincere thanks are also due to Dr Virash Gupta (Professor in
Microbiology; PAU, Ludhiana; for introduction to RAPD and
Cloning) and Dr Sanil George (Scientist, Rajiv Gandhi Centre of
Biotechnology, Trivandrum; for exposure to technique of Bar-
coding) for respective reasons.
 Dr Jagbir Singh Kirti (Professor in Entomology, Punjabi University,
Patiala), needs special thanks, as has been my real mentor during
my research for doctorate degree.
