Abstract: The Western Himalayan state of Uttarakhand in India represents five species of oaks of the genus Quercus that are important for conservation as they support rich biodiversity of fauna and also for their multiple utilization values for local communities living in the region. However, oak forest are under threat of extinction toddy, mainly due to anthropogenic pressures along with attack by many species of insects. Hence, there is a need to know the insect pest spectrum of oak forest and indentity those species which can cause damage to these trees, directly. As such field surveys across the oak forests of the state were carried out for 3 years (2017-2020) and revealed 114 species of insects infesting these 5 species of oaks. The comprehensive annotated checklist of insects infesting western Himalayan oaks in the state was prepared for 233 species (117 Lepidoptera; 99 Coleoptera, 16 Hemiptera and Diptera) so far recorded on them and is presented in this paper along with their classification, habit, month of incidence and species of oak tree infested .Break up of species in different families of each of these 4 orders recorded is given along with species in different families of each of these 4 orders recorded is given long with species capable of causing potential damage to oak trees. Management of key important pests i.e., stem and wood borders, defoliators, shootborers, acron weevils and sap sucking insects by using IPM methods is discussed.

Subject: Traditional knowledge of pest management and entomophagy: perspective on kiwi crop management by the Apatani tribe of Arunachal Pradesh, Northeast India
Keywords: Chafer, entomophagy, kiwi, pest control, traditional knowledge
Abstract: Conventional insect pest control methods and approaches
are being used in agroecosystem management. However,
some pest control methods affect human health and
are unsustainable. Consumption of some insect pests as
food by humans can be incorporated in a sustainable
manner to manage the pest species, which locally provide
some positive outputs. The traditional and sustainable
ethno-entomophagy practice of the Apatani tribe, inhabiting primarily the Ziro valley of Arunachal Pradesh,
North East India, can be considered a prime example
of such practices. They consume three species of chafer
beetles locally known as Jojer, Dikang-Diilang and SankoTapu, i.e. Anomala sp., Phyllophaga sp. and Lepidiota
sp. respectively. It is also known that the adults of these
species are pests of the kiwi plant (Actinidia deliciosa)
and chestnut tree species (Castanopsis spp.). In this
study, we unravel the practice of entomophagy of these
beetles by the Apatanese and understand its implications
for the sustainable management of agroecosystems

Abstract: A study was conducted to document the pollination index
of syrphid flies and to record the natural incidence of
syrphid larvae on fennel aphid, Hyadaphis coriandri.
Five different species of syrphid flies, viz. Episyrphus
balteatus, Ischiodon scutellaris, Paragus serratus, Dideopsis aegrota and Betasyrphus linga were recorded in the
flowers of fennel. E. balteatus ranked first in the order
of pollination index. The natural incidence of larvae of D.
aegrota was significantly higher in the umbels infested
with H. coriandri. The results of the study confirmed
the possible utility of fennel as a banker crop for the
natural proliferation of syrphid predators

Subject: Acaricide resistance among broad mite (Polyphagotarsonemus latus (Banks)) populations in Karnataka, India
Keywords: Acaricide, bioassay, Polyphagotarsonemus latus, stability, susceptibility.
Abstract: The broad mite, Polyphagotarsonemus latus (Banks), is
a cosmopolitan pest that attacks a wide range of economically important crops like hot and sweet peppers, mulberry, jute, tea and several ornamentals. This study
was undertaken to monitor the development of acaricide
resistance, if any, in five representative field-collected
populations of Karnataka, India. Bioassays were carried
out against five acaricide chemistries, and resistance
ratios were calculated by comparing the LC50 values of
field populations with the susceptible laboratory population (Pa-Lab). The resistance ratios varied from 26.03
to 81.16-fold for diafenthiuron, 27.35 to 83.47-fold for
dicofol, 9.72 to 45.42-fold for fenazaquin, 8.77 to 16.84-
fold for propargite and 48.37 to 163.39-fold for spiromesifen. Resistance to the acaricides was unstable in P.
latus as a decline in resistance (14.11–102.53-fold) was
observed over generations in the absence of selection
pressure. The results suggest that acaricides should be
sprayed at economic threshold levels or on a rotation
basis for one or more seasons for better management
of P. latus by delaying the development of resistance.

Subject: Nutritional composition of potato (Solanum tuberosum L.) genetic resources
Keywords: Cluster analysis, germplasm, nutritional compounds, potato, principal components
Abstract: Seventy-one germplasm lines comprising of commercial
Indian potato cultivars, advanced clones exotic and
indigenous cultivars were evaluated for nutritional
compounds. We observed significant variability in the
lines for anthocyanins (1.81–17.20 mg/100 g FW), carotenoids (4.75–27.75 µg/g FW), ascorbic acid (14.50–
85.00 mg/100 g FW) and total phenolics (19.22–73.54 mg
GAE/100 g FW). However, for zinc (10.62–27.58 ppm),
iron (30.49–56.29 ppm), and tuber dry matter content
(14–26%), only small variations were found. The anthocyanin, carotenoids, and total phenolic contents of indigenous cultivars and nutrient-rich advanced clones
were generally much higher than those of the common
variety. It is interesting to note that anthocyanin (r =
–0.46; –0.43), total carotenoids (r = –0.47; –0.38), ascorbic
acid (r = –0.27; –0.24) and tuber dry matter (r = –0.21,
–0.24) all had negative correlations with marketable
and total tuber yield respectively. Cluster analysis revealed that genotypes from clusters 1 and 3 can be used
in bio-fortification breeding. The results of this study
also reveal that two genotypes, viz. JEX/A-122 (Andigena line) and Kala Aloo (indigenous line) may be
used as breeding material to develop nutrient-rich potato varieties.

Subject: Extraction of Antarctic ice features using hybrid polarimetric RISAT-1 SAR data
Keywords: Classification accuracy, confusion matrix, hybrid polarimetry, ice features, m–χ decomposition, synthetic aperture radar data.
Abstract: Compact polarimetry has gained popularity due to its
advantages, such as larger swath, simple architecture
and low power consumption. The backscattered signal
and scattering decomposition vary for different targets
based on their electrical, geometrical and structural
properties. As of now, the potential of hybrid polarimetric synthetic aperture radar (SAR) data for exploring
Antarctic ice features is not fully explored. Here, we
present a comprehensive polarimetric feature analysis
and classification results of the hybrid polarimetric dataset acquired by RISAT-1 near the Indian Antarctic research station Maitri. The single-look complex images
have been subjected to polarimetric data processing for
extracting Antarctic ice features using POLSARPRO
software. The polarimetric coherence matrix is generated
and then filtered to eliminate speckles. Raney m–χ decomposition technique has been utilized to understand
the scattering mechanism of the targets. The decomposed
RGB image is classified using Wishart-supervised classification, and classification accuracy is assessed using
a confusion matrix. It is found that the comparatively
simple hybrid polarimetric SAR provides sufficient information to detect and discriminate various Antarctic
ice features. Features such as rifts, ice–rises, ice shelves
and icebergs are clearly discriminated using Wishartsupervised classification. It is also found that the overall
accuracy of the classification of study areas varies between 80% and 97%, suggesting a good classification
outcome.

Abstract: The soil carbon sinking ability is dominantly controlled
by local topographical settings, soil–crop management
and traditional farming practices on which the food
demand of the major population is dependent. The
degradation of natural resources causing poor soil
health is likely to strain the hilly and mountain ecosystem.
This study aims to map soil organic carbon (SOC) of
rice–fallow system under varying slopes and its changes
during the past 20 years under traditional management
practice using geospatial tools and techniques. Regression models of SOC were derived from remote sensing
(RS)-based indices using multiple linear regressionstepwise (MLR-stepwise), partial least square regression
(PLSR) and principal component analysis-regression
(PCA-R). The MLR-stepwise model was found to be
superior in performance with high R2 (0.87) and least
RMSE (0.026) compared to PLSR (R2 = 0.71 and RMSE =
0.05) and PCA-R (R2 = 0.27 and RMSE = 0.11) models
for SOC prediction.

Subject: Effect of confinement on cross-sectional performance of steel–concrete composite beams with solid and cellular steel sections
Keywords: Composite beams, concrete confinement, moment–curvature characteristics, solid and cellular steel sections
Abstract: The aim of this study was to compare the moment–curvature (M–φ) characteristics of a solid composite section
(SCS) and cellular composite section (CCS) of a beam
under a sagging moment. The strip method, based on
the principles of fundamental mechanics that consider
linear strain variation across composite sections, was
used to determine M–φ. It was first developed for SCS
for different parameters, i.e. the grade of concrete, unconfined and confinement strength of concrete, and effective width of a concrete slab, and then extended for
CCS. CCS had a 50% depth enhancement over the steel
section of SCS. Full interaction between the steel beam
and the concrete slab up to the failure of the slab was
assumed in the analysis. According to the M–φ analysis,
CCS enhances the ultimate moment capacity and ultimate curvature for unconfined and confined concrete.
Concrete confinement for CCS effectively boosted steel
material utilization and resulted in higher curvature
ductility before failure. The high concrete strength and
wider effective flange width of the slab resulted in high
ultimate moment capacity and ultimate curvature for
SCS and CCS for unconfined and confined concrete.

Subject: Fat supplementation: implication in dairy cattle
Keywords: Dairy cattle, essential fatty acids, fat supplementation, milk production, reproduction
Abstract: Supplementation of fat or oil in the ration of high yielding
dairy cattle increases the energy density of the ration
without altering the composition of the other ingredients.
A high proportion of free fatty acids in vegetable fat
possibly improves fat digestibility in the total gastrointestinal tract and has been associated with variable effects
on milk yield and milk fat composition. Vegetable fats
are rich sources of essential fatty acids, viz. linoleic and
linolenic acid, and varying amounts of monounsaturated
oleic acid. Polyunsaturated fatty acids (PUFAs) in dietary fat are important substrates for the synthesis of
reproductive hormones and prostaglandins and to augment the reproductive performance through stimulation
of the growth of ovarian follicles, increase in follicle
size and number, and increased function of corpus luteum
(CL) in cattle. PUFA undergoes biohydrogenation in
the rumen to produce conjugated linoleic acid (CLA).
The milk CLA is identified to reduce body fat levels, improve glycaemic profile, resynthesize glycogen, modulate
immune function, improve bone mineralization, prevent
heart diseases, atherosclerosis, diabetes and cancer in
humans. Significantly higher levels of fat/oil (>3%,
generally) in the diet may adversely affect the fermentation pattern through adverse effects on fibrolytic
bacteria and protozoa in the rumen, subsequently lowering the fibre and dry matter digestibility. To minimize
the effect of higher levels of fat on rumen fermentation,
fat may be supplied in a protected form that escapes
rumen fermentation and is subsequently utilized in the
lower digestive tract of high-yielding dairy cattle to produce beneficial effect

Abstract: This study analyses the causes and consequences of slope instability around the historical Himalayan town of Joshimath, Uttarakhand, India. The town is in the Higher Himalaya near the Main Central Thrust. The lithology constitutes fissile, shattered and sheared gneiss. Consequently, the slopes are
prone to land subsidence and mass wasting. In the last few decades rise in population has led to a
surge of infrastructure development, thus causing immense pressure on the finite resources and limited
accommodation space on precariously balanced vulnerable slopes. Particularly, the unplanned infrastructure development, lack of adequate drainage and excavation of roads through unstable debris
slopes are some of the reasons that seem to have accelerated the ongoing slope instability and land
subsidence

the current annual emissions of sovereign nation-states. Through a comprehensive review and assessment, this article argues that other metrics of country-wise emissions provide a more holistic and
unbiased view. The article argues that ranking per se by any metric is of minor value unless also
placed along the actual quantities. India’s cumulative emissions (excluding LULUCF, 1850–2019)
amount to only 4.31% of the global total, well behind the three leading emitters, the United States
(22.46%), the European Union (16.06%) and China (13.45%). Therefore, in terms of annual emissions, the story of India as the fourth largest emitter is very mistaken, as the gap between us and the
third is substantial. The article argues that national emissions must be judged by equity in mitigation
and in the light of climate action being undertaken. On both grounds, India, relative to its responsibility and what equity demands, is doing far more than her fair share

Subject: HPLC validation of phyllanthin, its seasonal variation in phyllanthus fraternus and evaluation of the procurement time
Keywords: Seasonal validation, Phyllanthus fraternus, Procurement time, Phyllanthin, HPLC-Validation
Abstract: Medicinal plants efficacy for various activities depends on the nature of primary, secondary metabolites and presence of its degree of quantity. The concentrations of secondary metabolites play a vital role for medicinal properties. The amount of secondary metabolites directly related with the growth of the herbs or plants, certainly depends on the collection time of the plant materials for which parts and which season they are acquired .Hence it is important to find out the best season for the collection of raw botanical materials for its desired therapeutic action in an effective manner and it is aimed to evaluate the best harvesting time for phyllanthus fraternus whole plant in terms of assay of phyllanthin through HPLC.

Subject: Quantitative estimation of Betulin in different plant parts of Dilleni pentagyna Roxb. through validated HPTLC method
Keywords: HPTLC, Betulin, Method validation, Dillenia pentagyna, quality control
Abstract: A new, simple an accurate high-performance liquid chromatographic (HPTLC) method was developed for estimation of betulin (BE) in fruits, leaves, root bark and stem bark of Dillenia pentagyna, a RET species of Madhya Pradesh state of India. HPTLC aluminium plates percoted with 0.2 mm layer of silica gel 60F 254 were used to separate BE from the plant samples using the mobile phase, petroleum ether: ethyl acetate: acetonitrile (8:2:0.1, v/v/v) .The anisaldehyde–sulphuric acid regent was used to derivatize the plate followed by heating at 105˚C on CAMAG HPTLC hot plate for 5 minutes. The peak corresponding to reference compound BE and that of the extract appeared at the same RF 0.21.Image of the plate was captured and HPTLC scan was performed densitometricaly at λmax = 580 nm under tungsten lamp in CAMAG TLC Scanner4 equipped with win CATS software. The developed HPTLC method was validated as per norms of the International Conference on Harmonization (ICH) for linearity, sensitivity, precision, accuracy and sepecificity. The BE content in fruit, leaf, root bark and stem bark samples of D.Pentagyna was found as 0.101 ± w found as 0.101 ± 0.03%, 0.091 ± 0.09, 0.368 ± 0.07 and 0.440 ± 0.11 % respectively.

Keywords: Semal, Bombax ceiba, mythological tree
Abstract: Semal (Bombax ceiba L) is tree with sharp thorns ,polyadelphous stamens, and a deciduous calyx on the morphological level, and concentric fibrous patches with calcium oxalate rosette crystals on the anatomical level. It is an integral part of many socio-cultural religious ceremonies, rites, rituals, traditions, customs and festivals of native communities. It is an ancient tree species found in moist evergreen and deciduous forests of many continents. Almost every part of this tree is employed as medicine. It has been reported to possess plethora of biological activities namely antianxiety, antihyperglycemic, hypoglycemic and hypolipidemic, insulin secretary and sensitization, antiglycation (antiageing), antisteoporetic and osteogenic, antiangiogenic, antitumorigenic,antioxidant,heptoprotective,neuroprotective , fibronolytic, androgenic and anabolic, aphrodisiac, and antimicrobial etc. It is well mentioned in a variety of traditional medicinal systems, including Ayurveda, Unani, Siddha, Traditional Chinese Medicine, and Tibetan Medicine. The flavonoids, phenolics, sesquiterpenoids, shamimicin, bombamalosides, bombamalones, bombastin, bombasin 4-0-glaucoside and bombalin have been observed major contributors for the therapeutic properties reported for Bombax ceiba. This review presents a conscise report of above observations.
