Abstract
Lilium is widely known as one of the most important bulbous cut flower internationally. Improper and inadequate post harvest handling results into quality losses for retailed flowers. To address this issue, a study was conducted to evaluate the effects of silver nanoparticles as higher concentration pulse or a lower concentration as vase solution on the postharvest performance of Lilium cut flowers. The 20 ppm pulsing of cut stems for 24 hours, followed by retention in 2 per cent sucrose solution substantially improve the relative fresh weight, water uptake, water balance, delayed the leaf yellowing. However, higher concentration (40 ppm) extended the vase life by 03 days as compared to the control flowers. The lower concentration (20 ppm) of nanosilver as holding solution enhanced the physiological parameters and controlled the senescence related processes in leaves and petals. Vase life was enhanced to 4.35 days as compare to flowers placed in distilled water as control. The present findings unequivocally highlight that a 40 ppm nanosilver pulse for 24 hours or a 20 ppm + 2% sucrose vase solution can significantly prolong the vase life and positively influence the physiological parameters of cut Lilium flowers.

Abstract
This study was performed on the collections of the National Zoological Collection of the Zoological Survey of India and described a new species in the “multidentati” Cyphoderus group from Bihar, India. This new species, Cyphoderus bihariensis sp. nov., is described with a distinguishing comparison among other species within this group. The new species is notably large compared to its counterparts in this group. This study also redescribed Cyphoderus javanus Börner, 1906 collected from various localities and habitats across India and provides additional morphological identification characters and chaetotaxy for taxonomic sufficiency. Earlier, India was home to nine Cyphoderus species from various localities across the country. Additionally, an identification key to the Indian Cyphoderus is included.

Abstract
Six Collembola species from five families and two orders are for the first time recorded from India. All the described new records are mainly from two states, West Bengal and Arunachal Pradesh and collected from the surveys conducted in the Eastern Himalayan Region. Sphyrotheca multifasciata (Reuter, 1881) (Sminthuridae), Sminthurinus bimaculatus Axelson, 1902 (Katiannidae), Dicranocentrus nepalensis Mari Mutt & Bhattacharjee, 1980 (Orchesellidae), Isotomurus plumosus Bagnall, 1940 (Isotomidae), Isotomurus pseudopalustris Carapelli, Frati, Fanciulli & Dallai, 2001, (Isotomidae), Willowsia jacobsoni (Börner, 1913) (Entomobryidae), are the Collembola species whose occurrence is first time observed in India. As a result of the present work Collembola fauna of India reached up to 348 species. Material examined, a brief description and microscopic images of the new records are provided in the present study.

Abstract
One new species and three new records of Tomocerus have been reported for the first time from India. The new species Tomocerus sikkimensis sp. nov. discovered from Gangtok, Sikkim (India) has been illustrated and described here. The new species differs from others in dental spine number, arrangement and mucro teeth number. Tomocerus (Ocreatomurus) qinae Yu, Yan & Liu, 2016, Tomocerus (Tomocerus) minor (Lubbock, 1862) and Tomocerus (Ocreatomurus) paraspinulus Gong, Qin & Yu, 2018 are the first time reported from the Indian states Arunachal Pradesh and West Bengal respectively. A key to the Indian species of Tomocerus has also been provided.

Abstract
Twenty spices were employed to preserve the cooked and uncooked fillet of Puntius sarana (Hamilton) and Puntius ticto (Hamilton). IC50 values of 2,2’-diphenyl-1-picrylhydrazyl(DPPH) based free radical scavenging activity ranged from 0.1123 μg ml-1 in turmeric to 13.035 μg ml-1 in roman coriander. Phenol content ranged from 0.365 μg g-1 in onion to 5.67 μg g-1 in clove. The raw and cooked fillets of P. sarana, and the cooked fillet of P. ticto, treated with garlic recorded the highest rates of thiobarbituric acid (TBA) reactivity (P< 0.05). For raw P. ticto, both the control and garlic treated fillet recorded higher rates of TBA reactivity (P< 0.05). Fillet of both fish species recorded higher TBA reactivity under raw condition, compared to cooked fillet. This condition was similar for the spice treated fillet. The exceptions were garlic, green and black cardamom, roman coriander and onion for P. sarana and garlic, cumin, field mustard, black pepper and poppy seed for P. ticto, where TBA reactivity was higher in cooked condition. It is recommended that spices with active phenolic antioxidants be used to inhibit the lipid oxidation in P. sarana and P. ticto. However, application of garlic extract for fillet preservation should be avoided until further documentation.

Abstract
Pasting is one of the most important properties of wheat starch determining the flour quality and functionality. Twenty three New Plant Type (NPT) wheat derivatives along with three checks (PBW 343, HD 2329, and Raj 3765) have been studied in multi-location trials to assess the variation and environment induced fluctuations for their starch pasting properties. Although all flour pasting characteristics varied, Breakdown Viscosity (BV) and Setback Viscosity (SV) exhibited greater variability across environments. Additive Main effects and Multiplicative Interaction (AMMI) analysis indicated significant interactions between Genotypes and Environments Interaction (GEI) in starch pasting properties. Genotypes accounted largest proportion (39.78%) of the Sum of squares (SQ) for peak viscosity (PV) followed by environments (33.30%) and GEI (33.30%). Trough Viscosity (TV), GEI accounted for the largest proportion (40.44%) of the SQ followed by environments (31.76%) and genotypes (27.80%). Genotypes accounted for the largest proportion (44.0%) of the SQ for (BV) followed by environments (33.30%) and GEI (21.59%). With respect to FV, environments accounted for the largest proportion (43.07%) of the SQ followed by GEI (30.84%) and genotypes (26.09%). Environments accounted for the largest proportion (52.48%) of the SQ followed by genotypes (23.89%) and GEI (23.65%) for SV. The interactions between genotype and locations differed greatly; however, some genotypes apparently found to be specifically adaptable to growth location. Correlation among starch pasting characteristics revealed that significant positive correlations were found between PV and BV, FV and TV, as well as SV and FV in all the individual environments tested that can be utilized in selection and simultaneous improvement in for starch quality improvement.
