For this purpose, fingerlings were fed with diets containing aqueous extracts of Nishinda (Vitex negundo) and garlic (Allium sativum) pest. For immunostimulatory food additives caused a good result compared to the control group. After 90 days experiment SGR% (Specific growth rate) is in aquarium A, B and control were 0.92, 0.89 and 0.61 respectfully. The mortality rate % in A, B and control were 44, 40 and 76 respectively.

Mortality was assessed after 24, 48 and 72 h of treatment and LD50 values were calculated at the respective time intervals. It was observed that T. castaneum is more susceptible to the lignin than the other test insects. Repellent activity of the product was conducted for T. castaneum and T. confusum. All the concentrations of the product were found to be repellent to both the insect species. Strong repellent activity was observed at concentrations of 471.57 and 628.76 µg.cm-2 to T. confusum showing the repellency of class V activity.

It was observed that different leaf extract of A. cathartica exhibited less antioxidant activity in comparison to that of the extract of M. elengi. The highest antioxidant activity (4.5880.001 g/mL) was found in the dia-ion resin adsorbed fraction of M. elengi and the least activity (1.82±0.002 g/mL) was found in the methanolic fraction of A. cathartica. From the results of antimicrobial activity test, it was observed that the petroleum ether fraction of A. cathartica showed the maximum inhibition with the diameter Original Research Article

Methodology: The antimicrobial and antifungal properties have been characterized by disc diffusion method. The cytotoxicity property was determined against brine shrimp nauplii. Results and Conclusion: Among the four fractionates, the dia-ion resin adsorbed fraction showed the highest activity towards the S. aureus, E. coli bacteria and the fungus C. albicans with the zone inhibition of 12∼13 mm which was comparable with that of the standard Kanamycin. The chloroform, petroleum ether, and ethyl acetate fraction was exhibited least activity toward the bacteria and Original Research Article

There are more or less 200 stored grain and stored products attacking insects and mites species are found (Khanam et al., 2005). Among these, the red flour beetle, Tribolium castaneum (Coleoptera: Tenebrionidae) and the confused flour beetle, Tribolium confusum Coleoptera: Tenebrionidae) are serious pest of a great variety of stored products, which are cosmopolitan in distribution. Both the adults and larvae cause serious damage to stored wheat, maize and wheat flour. Several insecticides are used indiscriminately to control this pest. But indiscriminate use of chemical pesticides produced many serious problems, viz. genetic resistance of pest species, toxic residues, threat to wild life, etc. (Talukder et al., 2011). In fact this led a worldwide interest in the development of botanical pest control agent. The main advantages of botanicals are that, these can be produced easily by farmers and are potentially less expensive. Zingiber cassumunar Roxb. commonly known as Bonada (Family: Zingiberaceae) is used in folklore remedies as a single plant or as component of herbal recipes for the treatment of inflammation, sprains, rheumatism, muscular pain wounds and also as mosquito repellent, a carminative, a mild laxative and an anti dysenteric agent in Bangladesh and many Asian countries (Bhuiyan et al., (2008). Z. cassumunar grows abundantly in Bangladesh. It is a herb with elongated leafy stem. Stem is 1.2 to 1.8cm high. Leaves are sub sessile 23 to 35cm oblong. Bhuiyan and Co-workers (Bhuiyan et al., 2008) identified 32 volatile constituents in the rhizome oil of Z. cassumunar. The main components in rhizome oil were triquinance-1,4-bis (methoxy) (26.47%), Z-ocimene (21.97 % and terpinen-4-ol (18.45%). Wanauppathamkul (2003) also reported the presence of Sabinene (25-45%), γ-tepinene (5-10%), α-Tepinene (2-5%), Terpinen-4-ol (25-45%) and (E)-1-(3,4-dimethoxyphenyl) butadiene(DMPBD) (1-10%) as active chemicals in the Z. cassumunar essential oil. Several workers reported the chemical composition, anti-inflammatory, antimicrobial and insecticidal activity of Z. cassumunar

The LD 5 0 values indicated that the toxicity of A. reticulata leaf extracts on eggs of different species and strains of Tribolium spp. followed the order : T. confusum > T. castaneum (BCSIR strain) > T. castaneum (CR-1 strains).

Emulsified oil can easily mix with water and also revealed the same insecticidal activity as essential oil of plants that could be used in store as well as in the field as an alternative synthetic insecticide. Objectives: The objective of this study is to investigate the efficacy of emulsified petroleum ether extract of Acorus calamus L. rhizome alone and three other combination of plant materials against three stored product pests, viz. Callosobruchus chinensis L., Sitophilus oryzae (L.) and Tribolium castaneum (Herbst) in adult phase in laboratories condition. Materials and method – Petroleum ether extract of different plant parts were emulsified. The emulsified products were A. calamus rhizome alone, A. calamus + Corchorus capsularis L. seed, A. calamus + Thevetia neriifolia Juss. seed and A. calamus + Zingiber cassumunar Roxb. rhizome. The residual film technique method was conducted to deter...

Methods: Oral glucose tolerance test model and alloxan induced diabetic test model were performed to evaluate antidiabetic activity of EEPGL at doses of 1.00, 0.50 and 0.75 g/kg respectively. For antidiarrhoeal effects of EEPGL, castor oil-induced diarrhoea model and gastrointestinal motility test with barium sulphate milk model were also assessed at doses of 750, 500 and 250 mg/kg, respectively. Results: Administration of EEPGL at doses 1.00 and 0.50 g/kg significantly (P<0.05) decreased blood glucose levels in oral glucose tolerance test model as well as 0.75 g/kg dose in alloxan induced diabetic test model in Wister rats (P<0.001). Application of EEPGL at doses of 750 and 500 mg/kg showed antidiarrhoeal effect in castor oil-induced diarrhoeal model (P<0.001 and P<0.01, respectively), and 750 mg/kg (P<0.01), 500 and 250 mg/kg (P<0.05) doses in barium sulphate milk model in aforesaid animals. Conclusions: These results exhibited the significant antidiabetic and antidiarrhoeal activities of ethanolic extracts of Psidium guajava leave in Wister rats
