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...

OBJECTIVE To investigate the larvicidal and ovicidal efficacy of different extracts of Cardiospermum halicacabum L. against Culex quinquefasciatus Say and Aedes aegypti L. (Diptera: Culicidae). MATERIALS AND METHODS Larvicidal efficacy of the crude leaf extracts of Cardiospermum halicacabum with five different solvents like benzene, hexane, ethyl acetate, methanol and chloroform was tested ag...

Purpose: To determine larvicidal activity of the essential oil derived from Illicium henryi Diels (Illiciaceae) leaf and stem against the larvae of Aedes albopictus Skuse. Methods: The essential oil of I. henryi leaves was obtained by hydrodistillation and analyzed by gas chromatography (GC) and gas chromaotography-mass spectrometry (GC-MS). The activity of the oil was evaluated, using World He...

Sixty plant species were collected in the Ivory Coast on the basis of an ethnobotanical literature using the following three criteria: activity against worms, diarrhoea and/or abdominal pain. Eighty six plant extracts were prepared using 90% ethanol and tested for potential anthelminthic activities with a larvicidal test of Haemonchus contortus. 25.6% of the extracts showed a high activity, 12....

The larvicidal activity and repellency of 5 plant essential oils--thyme oil, catnip oil, amyris oil, eucalyptus oil, and cinnamon oil--were tested against 3 mosquito species: Aedes albopictus, Ae. aegypti, and Culex pipiens pallens. Larvicidal activity of these essentials oils was evaluated in the laboratory against 4th instars of each of the 3 mosquito species, and amyris oil demonstrated the ...

Screening of twenty five plant extracts for larvicidal activity against Culex quinquefasciatus Say (Diptera: Culicidae) Samuel Tennyson, K John Ravindran, S Arivoli Department of Zoology, Madras Christian College, 600 059, Tamilnadu, India National Institute of Malaria Research (ICMR), Field Unit Chennai, National Institute of Epidemiology Campus, Chennai 600 077, Tamilnadu, India P.G. & Resear...

Natural insecticides from plant origin against mosquito vectors have been the main concern for research due to their high level of eco-safety. Control of mosquitoes in their larval stages are an ideal method since Aedes larvae are aquatic, thus it is easier to deal with them in this habitat. The present study was specifically conducted to explore the larvicidal efficacy of different plant parts...

Inbred P- and A-strain mice are deficient in their capacity to develop resistance to challenge infection in response to vaccination with irradiated cercariae of Schistosoma mansoni and are also defective in their cell-mediated response as assessed by the activity of antigen-elicited macrophages in killing schistosome larvae in vitro. In contrast, vaccinated (P x A)F1 mice displayed high levels ...
