The hepatoprotective activity of the alcoholic extract of Rosa damascena was studied against paracetamol induced acute hepatotoxicity in rats. Liver damage was assessed by estimating serum enzyme activities of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and histopathology of liver tissue. Pre- and post-treatment with ethanolic extracts showed a dose-dependent reduction of paracetamol induced elevated serum levels of enzyme activity. The mechanism underlying the protective effects was assayed in vitro and the R. damascena extracts displayed dosedependent free radical activity using DPPH ($IC_{50}=162.525\;{\mu}g/ml$) and TBA method. The hepatoprotective action was confirmed by histopathological observation. The ethanolic extracts reversed paracetamol induced liver injury. These results suggest that the hepatoprotective effects of R. damascena extracts are related to its antioxidative activity.

Mazed, MA,Alam, MZ,Miah, MRU,Hossain, MS,Mian, MIH Bangladesh Journals Online 2016 Bangladesh journal of agricultural research Vol.41 No.4

<P>A survey was conducted during July 2009 to October 2010 to know the occurrence of okra shoot and fruit borer species that infest okra in Bangladesh. Infested okra fruits were collected from eleven selected locations representing 11 Agro-ecological Zones of Bangladesh and reared in the laboratory. A total of 423 adult individuals consisting of 188 male and 235 female moths emerged from the infested fruits. The male and female ratio was 1.00?1.25. The morphological characteristics of adult moths were recorded. Head and thorax of adults are ochreous white; forewings are pale white with a wedge shaped horizontal green patch in the middle and hind wings are silvery creamy white in color. The males are smaller than the females in size and the females are Vshaped at the end of the anal part but the males have thick hairs at the end of the anal part. Pupae are chocolate brown, bluntly rounded and enclosed in grey colored inverted boat shaped cocoon formed in the fruit or in the sand. Full grown caterpillars measured 1.64 cm in length and their color is brownish with white streaks dorsally and pale yellow ventrally, without finger tipped process. The recorded morphological characteristics ware compared with standard key and the insects were identified as Earias vittella belonging to the family Noctuidae.Bangladesh J. Agril.

Mazed, MA,Alam, MZ,Miah, MRU,Hossain, MS,Awal, MA Bangladesh Journals Online 2017 Bangladesh journal of agricultural research Vol.42 No.2

<P>An experiment was conducted to evaluate the effectiveness of some selected insecticides and botanicals against okra shoot and fruit borer Earias vittella F. under field conditions. The insecticides tested were Relothrin 10EC @ 1ml l-1, Marshal 20EC @ 2ml l-1and Riva 2.5 EC @ ml l-1; and the botanicals were NSKE @ 50g l-1, Neem leaf extract @ 100g l-1 and Bishkatali leaf extract @ 100g l-1. An additional treatment of Mechanical control (hand picking) and an untreated control were maintained in the experiment for comparison. All treatments were applied at 15 days interval. Shoot infestation was the lowest in Marshal 20EC treated plot (4.34% at pre-fruiting and 3.55% at fruiting stage) and the highest was in untreated control plot (21.4%). The lowest fruit infestation by okra shoot and fruit borer was obtained with Marshal 20EC (5.07% n/n and 3.65% w/w) followed by Relothrin 10EC (5.43% n/n and 4.27% w/w) and the highest infestation was observed under untreated control plot (19.67% n/n and 19.81% w/w). The reduction of fruit infestation over untreated control ranged from 56.93-81.55% by number and 43.47-74.22% by weight. The highest marketable yield (10.46 t ha-1) was obtained in Marshal 20EC treated plot followed by in Relothrin 10EC 10.30 t ha-1 with the maximum benefit cost ratio (BCR) 6.72.Bangladesh J. Agril.

Chowdhury, MAH,Alam, MZ,Hossain, MS,Suh, SJ,Kwon, YJ Bangladesh Journals Online 2017 Bangladesh journal of agricultural research Vol.42 No.3

<P>The present study was conducted during October 2014 to June 2015 in the farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur to find out the most effective management option (s) against brinjal shoot and fruit borer (BSFB) with 6 treatments namely, Beauveria bassiana, 1´109 CFU @ g l-1, Bioneem 0.3 EC (Azadirachtin) @ 1.5 ml l-1, Tracer 45 SC (Spinosad) @ 0.4 ml l-1, Vertimec 1.8 EC (Abamectin) @ 1.2 ml l-1 of water, Mechanical control (hand picking) with clean cultivation and untreated control. Results revealed that shoot infestation at pre-fruiting stage was the lowest in Bioneem 0.3 EC (4.34%) and at fruiting stage in Tracer 45 SC treated plot (7.75%) and the highest was in untreated control plot (17.94% at pre-fruiting stage and 39.46 at fruiting stage). The lowest fruit infestation by BSFB was obtained with Tracer 45 SC (8.16% n/n and 10.0% w/w) followed by B. bassiana, 1´109 CFU (23.23% n/n and 18.27% w/w) and the highest infestation was observed under untreated control plot (48.59% n/n and 32.09% w/w). Percent reduction of infested fruit by number (83.21%) and weight (68.84%) over untreated control was higher in Tracer 45 SC treated plot resulting significantly higher marketable yield. Therefore, the significant highest marketable yield (34.39 t ha-1) was harvested in the plot treated with Tracer 45 SC followed by 22.78 t ha-1 with B. bassiana, 1´109 CFU and 19.26 t ha-1 from Vertimec 1.8 EC treated plot. The highest benefit cost ratio of 3.05 was obtained from Tracer 45 SC followed by 2.93 in B. bassiana, 1´109 CFU and 2.89 with Vertimec 1.8 EC sprayed plot.Bangladesh J. Agril.
