Aedes aegypti (L.) is known as vector of dengue and chikungunya fever. Larvicides are used to control this vector. We evaluated the efficacy of newly developed formulations of larvicides to control Ae. aegypti under field conditions for 24 weeks post single application. Mosdop P and Mosdop TB containing diflubenzuron (2% and 40 mg/tablet, respectively) as the active ingredient, were applied at ...

Fasciolosis is a widespread parasitosis of farm live-stock in many developing countries. For this reason, it is necessary to search for new substances against parasitic diseases caused by flukes. Indeed, a wide variety of terrestrial plants have been subjected to chemical and pharmacological screening in order to discover their potential for human medicinal use. The molluscicidal and larvicidal...

BACKGROUND To study the chemical constituents and larvicidal activity of essential oil extracted from the leaves of Coccinia grandis against three mosquito species. METHODS Essential oil was extracted by hydro distillation using clevenger apparatus and was analyzed for chemical constituents by gas chromatography-mass spectrophotometry (GC-MS). Larvicidal activity was recorded after 12 and 24h...

This investigation examined the molluscicidal and larvicidal activity of eight plants that are used in the traditional medicine of the Pankararé indigenous people in the Raso da Catarina region, Bahia state, Brazil. The tested plants were chosen based on the results of previous studies. Only those plants that were used either as insect repellents or to treat intestinal parasitic infections were...

Objective: Fascioliasis caused by Fasciola hepatica L. (Fasciolidae), a digenetic trematode, is a parasitic disease infecting many people worldwide. The present study was carried out to evaluate the molluscicidal and larvicidal activities of Capparis spinosa L. (Capparaceae) aerial parts against Galba truncatula Müll. (Lymnaeidae) and Fasciola hepatica larval stages contaminating this snail in ...

Insecticide resistance has been known to be prevalent in several insect species including mosquito. It has become a major problem in vector control programs due to pesticide resistance through detoxification enzymes. The present study aimed to compare between the larvicidal action of some organophosphorus insecticides (fenitrothion, malathion and temephos) commonly used in larval control progra...

Andiroba (Carapa guianensis) seeds are the source of an oil with a wide range of biological activities and ethnopharmacological uses. However, few studies have devoted attention to innovative formulations, including nanoemulsions. The present study aimed to obtain a colloidal system with the andiroba oil using a low-energy and organic-solvent-free method. Moreover, the preliminary residual larv...

The present study evaluated thephenolics composition and biological activities of various extracts Cyclamen coum. antioxidant properties these plant wasdetermined using the scavengingmethods (DPPH andABTS), total test systems (β-carotene/linoleic acid), reducing power (FRAP) assays.The antibacterial effect was examined with MIC method. phenolics were identified HPLC brine shrimp lethality used ...

In Ayurveda, Blumea lacera extraction has been found cast-off in the management of various sympathetic diseases and is also to exhibit hypoglycaemic, anti-diarrhoeal, larvicidal, antioxidant antimicrobial properties. contain astringent, stomachic, antipyretic, diuretic, cure bronchitis fever. To find out most suitable part plant which will be used for killing mosquito larvae. How do produce eff...

The physiological role of carbonic anhydrases in pH and ion regulation is crucial to insect survival. We examined the toxic and neurophysiological effects of five carbonic anhydrase inhibitors (CAIs) against Aedes aegypti. The 24 h larvicidal toxicities followed this rank order of potency: dichlorphenamide > methazolamide > acetazolamide = brinzolamide = dorzolamide. Larvicidal activity increas...
