BACKGROUND Ferulago carduchorum Boiss and Hausskn belongs to the Apiaceae family. This plant grows in west part of Iran that local people added it to dairy and oil ghee to delay expiration date and give them a pleasant taste. The aim of this study was to investigate the antioxidant, antimicrobial, acetyl cholinesterase inhibition, cytotoxic, larvicidal activities and composition of essential oi...

BACKGROUND Within the framework to control mosquitoes, ovicidal, larvicidal and pupicidal activity of Annona senegalensis leaf extract and its 4 fractions against Anopheles gambiae and Culex quinquefasciatus were evaluated in the laboratory conditions. METHODS Ovicidal test was performed by submitting at least 100 eggs of mosquitoes to 125, 250, 500, 1000 and 2000 ppm concentrations, while la...

Bacillus cereus VCRC 641 was found to be an alternate larvicidal bacterial agent which newly isolated from fresh water fish, Clarias batrachus (walking cat fish). The protein responsible for mosquito toxic effect separated and purified by Sephacryl S-200 column chromatography NATIVE PAGE. It observed that a unique with molecular weight of 70kDa the factor killing effect. Further analysis liquid...

The anthelmintic activity of methanolic, aqueous and hydroalcoholic extracts of flower of Mallotus phillipensis was assessed invitro using larvicidal activity on L3 stage larvae of Haemonchus contortus. Phytochemical analysis was done using standard techniques and the acute oral toxicity of the extracts were studied in rats as per OECD guidelines 420. Freshly collected faeces from infected goat...

The essential oils of four Guarea species collected at Manaus (Amazonas, Brazil) were obtained by hydrodistillation and analyzed by GC-MS. Except for one diterpene detected, the compounds identified in the essential oils were hydrocarbons and oxygenated sesquiterpenes. The major sesquiterpenes were alpha-santalene (26.26%) and alpha-copaene (14.61%) from G. convergens branches; caryophyllene ep...

Background We aimed to investigate different biological properties of aerial parts essential oil of Ferulago trifida Boiss and larvicidal activity of its volatile oils from all parts of plant. Methods Essential oil was prepared by steam distillation and analyzed by Gas chromatography and GC/Mass. Antioxidant, antimicrobial, cytotoxic effects and AChE inhibitory of the oil were investigated us...

The objectives of this study were to optimize protease production from the nematophagous fungus Monacrosporium thaumasium (NF34a) and evaluate its larvicidal activity and biological stability. An isolate of the nematophagous fungus Monacrosporium thaumasium (NF34a) was used to produce the enzyme. The Plackett-Burman design was used in order to scan which components of the culture medium could h...

Cyt2Aa2 is a mosquito larvicidal and cytolytic toxin produced by Bacillus thuringiensis subsp. darmstadiensis. The toxin becomes inactive when isoleucine at position 150 was replaced by alanine. To investigate the functional role of this position, Ile150 was substituted with Leu, Phe, Glu and Lys. All mutant proteins were produced at high level, solubilized in carbonate buffer and yielded prote...

The frequent use of systemic insecticides to manage insect pests leads to a destabilisation of ecosystem and enhanced resistance to insecticides and pests suggesting a clear need for alternatives. In addition, increasing documentation of negative environmental and health impact of synthetic insecticides and increasingly stringent environmental regulation of pesticides have resulted in renewed i...

Vector control is the foremost step to diminish the mosquito borne diseases as the proper vaccinations are yet to develop against those obnoxious diseases. After many resistant cases, it is important to develop other sources of eco-friendly insecticides. The present piece of study was designed to evaluate the mosquito larvicidal efficacy of Operculina turpethum against malarial vector Anopheles...
