Larvicidal efficacy of Capsicum annum against Anopheles stephensi and Culex quinquefasciatus.

Larvicidal efficacy of Ficus benghalensis L. plant leaf extracts against Culex quinquefasciatus Say, Aedes aegypti L. and Anopheles stephensi L. (Diptera: Culicidae).

OBJECTIVE To investigate the larvicidal efficacy of different extracts of Ficus benghalensis L. against Culex quinquefasciatus Say, Aedes aegypti L. and Anopheles stephensi L. (Diptera: Culicidae). MATERIALS AND METHODS Larvicidal efficacy of the crude leaf extracts of Ficus benghalensis with three different solvents like methanol, benzene and acetone was tested against the early second, thir...

Larvicidal and knockdown effects of some essential oils against Culex quinquefasciatus Say, Aedes aegypti (L.) and Anopheles stephensi (Liston)

Efficacy of 25 essential oils was screened against filarial vector, Culex quinquefasciatus, for their larvicidal and knockdown effects in a preliminary study. Of these, 8 oils viz. calamus oil, cinnamon oil, citronella oil, clove oil, eucalyptus oil, lemon oil, mentha oil and orange oil exhibited 100% larvicidal activity at 1000 ppm and 100% knockdown effect at 10% concentration. These 8 oils w...

Bioefficacy of Flindersine against Helicoverpa armigera Hübner, Spodoptera litura Fabricius, Anopheles stephensis Liston. and Culex quinquefasciatus Say

Flindersine, an alkaloid isolated from Toddalia asiatica, was evaluated for their antifeedant, larvicidal and growth inhibitory activities against Helicoverpa armigera, Spodoptera litura and larvicidal activity against vector mosquitoes Anopheles stephensi and Culex quinquefasciatus. For this, leaf disc no choice method was used for agricultural pests; larvicidal activity was tested on second a...

Mosquito larvicidal properties of Mirabilis jalapa (Nyctaginaceae) against Anopheles stephensi, Aedes aegypti & Culex quinquefasciatus (Diptera: Culicidae)

Larvicidal activity of neem and karanja oil cakes against mosquito vectors, Culex quinquefasciatus (say), Aedes aegypti (L.) and Anopheles stephensi (L.).

Larvicidal effect of neem (Azadirachta indica) and karanja (Pongamia glabra) oil cakes (individuals and combination) was studied against mosquito species. Both the oil cakes showed larvicidal activity against the mosquito species tested. The combination of neem and karanja oil cakes in equal proportion proved to have better effect than the individual treatments. The combination of the two oil c...

Evaluation of mosquito larvicidal efficacy of leaf extract of a cactus plant, Agave sisalana

The leaf extract of Agave sisalana was tested as a larvicide against three vector mosquito species viz., Anopheles stephensi, Culex quinquefasciatus and Aedes aegypti. Preliminary results showed that the 2% dilution of the leaf extract produced 100% mortality of IIIrd instar larvae of An. stephensi and 1% dilution produced 100% mortality in case of Cx. quinquefasciatus and Ae. aegypti. For furt...
