Aim: To investigate the effect of biotic and abiotic factors on the population dynamics of brown planthopper Nilaparvata lugens (Stal) (Hemiptera: Delphacidae) in the middle Gangetic plains of India. Methodology: Field trials were conducted in the middle Gangetic plains of India at Agricultural Research Farm, B.H.U., Varanasi, Uttar Pradesh, India during Kharif season of 2018 and 2019 on the variety Swarna sub-1 to study the population dynamics and certain biotic and abiotic interaction with brown planthopper. Results: During Kharif 2018 and 2019, the highest mean number of brown planthopper population (45.00 ± 2.31 and 39.33 ±1.82 nos., respectively) were recorded during September in both seasons. Abiotic factors such as rainfall (r = - 0.556), relative humidity in the morning (r = 0.476), maximum temperature (r = 0.511), and sunshine hour (r = - 0.546) influenced planthopper population dynamics, and predictions were made with reasonable accuracy (R2 = 0.89) using the principal component regression analysis technique. Crop phenology was the most influential biotic factor on pest population density. The crop's booting stage had the highest incidence of planthoppers. Three different predatory populations (wolf spider, damselfly and ladybird beetle) were observed to feed on planthoppers in Kharif 2018 and four different predatory populations (wolf spider, damselfly, ladybird beetle and green mirid bug) were observed to feed on planthoppers in Kharif 2019, resulting in a reduction in crop pest density. Interpretation: These findings can be used to develop the precise management strategies for brown planthopper in the rice ecosystem. © Triveni Enterprises, Lucknow (India)
Field efficacy of some combination insecticide formulations against paddy planthoppers
(Society of Pesticide Science India, 2019) K.R. Sharma; S.V.S. Raju
Comparative field efficacy of certain insecticide combination formulations with their sole insecticidal treatments is reported against rice planthoppers [brown (BPH) and white backed (WBPH)] during kharif 2016. The plots treated with fipronil 5 per cent + buprofezin 20 per cent SC @ 62.5+250 g a.i. ha-1 recorded the lowest number of BPH population (3.83 and 2.61 per 5 hills) in the first and second insecticidal sprays, respectively, followed by indoxacarb 10 per cent + thiamethoxam 10 per cent WG @ 50 + 50 g a.i. ha-1 (4.81 and 3.45 per 5 hills, respectively). The sole treatments of thiamethoxam 25WG @ 25 g a.i. ha-1 and buprofezin 25WG @ 50 g a.i. ha-1 performed as the third and fourth best treatments, respectively. The WBPH population was low in plots treated with fipronil + buprofezin EC (2.95 and 2.60 per 5 hills) after the first and second insecticidal sprays, respectively, followed by indoxacarb + thiamethoxam WG (3.83 and 3.36 per 5 hills, respectively). The highest population was recorded in untreated control. The highest per cent yield over control was recorded in fipronil + buprofezin EC treated plot (47.84), followed by indoxacarb + thiamethoxam 10 WG (44.88). © 2019, Society of Pesticide Science India.

Role of the indigenous drug saptamrita lauha in hemorrhagic retinopathies.
(1992) K.R. Sharma; R.P. Bhatia; V. Kumar
A clinical study was done on 48 eyes to assess the role of an indigenous drug, Saptamrita Lauha, in the absorption of hemorrhages and prevention of their recurrence in retinopathic eyes. Rapid absorption of retinal hemorrhages was observed in both treated groups: diabetic and hypertensive (mean durations, 16 days and 17.83 days, respectively). In three eyes, the hemorrhage cleared completely; partial clearance was observed in the rest of the eyes. Recurrence of a hemorrhagic episode was less in treated eyes (25% in each group) compared with control eyes (60% in diabetic and 50% in hypertensive patients). This study suggests that Saptamrita Lauha may hasten the process of retinal hemorrhage absorption and prevent its recurrence. The beneficial effect could be attributed to the flavanoid-like properties of one of the ingredients of this natural product.
Successful non operative treatment of high rectal fistula
(1976) P.J. Deshpande; K.R. Sharma
The present paper deals with a study of 50 cases having a high internal opening or an abscess cavity above the levator ani muscle. These cases of high rectal fistula invariably end up with complications after surgery in the form of injuries to the anal sphincters leading to incontinence. The term 'high rectal' denotes the types of fistulae having exceptionally long tracts and includes the 'high anal' and 'ano rectal' varieties according to Milligan Morgan's classification. The technique of treatment used involves ligating the entire fistulous tract with a caustic ligature without performing an excisional therapy. This ligature is prepared by repeatedly smearing a size 20 surgical thread with certain vegetable caustics as described in the ancient Indian literature and several times reported by us previously. The insertion of the thread into the fistulous tract can be achieved without much difficulty with the help of specially designed instruments. This treatment has been tried in 50 cases of high rectal fistula with exceedingly good results.
