The seed powder of Abrus precatorius L. has traditionally been used as oral contraceptive agent by the women in some rural areas in Bangladesh. The present study aimed to examine the antifertility activity of A. precatorius seed extracts in experimental female rats. Finely ground seeds were extracted with aqueous acetone followed by successive partitioning with n-hexane, ethyl acetate (EtOAc), methanol (MeOH) and water. Water suspended crude seed powder, organic fractions of acetone extract and a standard contraceptive drug (Nordette®28) were separately administered orally to the female rats for 30 days. n-Hexane, EtOAc and MeOH solubles at the doses of 2, 4 and 6mg/rat/day, respectively and crude seed powder at 100 mg/rat/day exhibited 100% antifertility activity with lowest levels of serum luteinizing hormone (LH), follicle stimulating hormone (FSH)and 17β-estradiol. Histological study of ovary and uterus of these rats exhibited reduced number of developing follicles and increased number of atretic follicles in the ovary, and fewer uterine glands with shrunken morphology, reduced endometrial height, poor vascularity and compact stroma in uterus. However, the activities of serum glutamate oxaloacetate transaminase and serum glutamate pyruvate transaminase and the body weight of the rats remained almost unaffected in all the seed extract treated rats compared to control. These results suggest that A. precatorius seed extracts reduced the levels of serum FSH, LH and 17β-estradiol probably by affecting hypothalamic-pituitary-gonadal axis. The reduced levels of these hormones might have affected the oestrous cycle, follicular development, and subsequently the establishment of pregnancy in treated rats.

Effectiveness of some selected insecticides and botanicals against okra shoot and fruit borer
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.

Identification of okra shoot and fruit borer infesting okra and their distribution in Bangladesh
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.

Prevalence and risk factors of helminth infections in cattle of Bangladesh
( AKMA Rahman ),( N Begum ),( M Nooruddin ),( Md Siddiqur Rahman ),( MA Hossain ),( Hee Jong Song ) 한국가축위생학회 2009 韓國家畜衛生學會誌 Vol.32 No.3
A cross-sectional survey was undertaken to identify risk factors and clinical signs associated with parasitic helminth infections of cattle in Mymensignh district of Bangladesh. A non-random convenience sampling method was used to select 138 animals from 40 farmers/herds. The eggs per gram of faeces (epg) for nematodes and trematodes were determined by McMaster and Stoll`s methods respectively. Animal-level and herd-level data were recorded by means of a questionnaire. Multicollinearity amongst explanatory variables were assessed using 2×2 X2 test and one variable in a pair was dropped if P?0.05 for multiple logistic regression models. Association study between outcomdels. explanatory variables was conducted using classification tree, random forests and multiple logistic regression. A positive epg was considered as infected. Analyses were performed using STATA(R), version 8.0/Intercrmled and R(R), Version 2.3.0. Seventy eight percent (78%) of the cattle were found to be infected with at least one type of helminth. Twenty four (24) pairs of combinations of explanatory variables showed significant associations. Mon animals (OR=3. inp=.006, 95% CI=1.4, 7.7) were associated with significantly increasednpssion modeof nematode infection. Female cattle of the study area are mostly cross-breed, kept indrme, fe. elatively good diet and not used for draught purpose. Mon s are used for draught purpose thereby more exposed to nematode infective stage and provided with Aelatively prme diet. So stressed male cattle may become more susceptible to nematode infection. All of the three statistical techniques selected gender and rumen motility as most important variables in association with nematode infection in cattle. The result of this survey can only be extrapolated to the periurban cattle population of traditional management system.
