The current state of knowledge regarding phytochemical sources and mosquitocidal activity, their mode of action on the target population, variation in their larvicidal activity according to mosquito species, instar specificity, polarity of solvents used during extraction, nature of active ingredient, and promising developments made in the biological control of mosquitoes by plant derived secondary metabolites are reviewed.

The results of the review reveal that the use of Solanaceous plant extracts have the potential to be utilized as a good, easily available, biodegradable, non-toxic and in having eco-friendly approach for the control of mosquito population.

In this review article, the current knowledge of phytochemical sources exhibiting larvicidal activity and their variations in response to solvents used for their extraction is underlined and comprehensive information can be gainfully employed for the development of herbal larVicidal formulations and nanopesticides against insecticide-resistant vector species in the near future.

An attempt has been made to develop an eco-friendly dhoop sticks containing Cow urine, cow dung, plant material that not only controlled mosquitoes but also reduced air micro flora from surrounding area.

This review aims to provide details on current advances in plant‐based products (plant compounds, extracts, and essential oils), which are used to control all the life cycle stages of the mosquito genera Aedes, Anopheles, and Culex.

The present work was aimed at finding the antimalarial activity of some medicinal plants like Momoradica charantia, Glyricidia sepium, Vitex neegundo, Gardenia jasminoides, Carica papaya, Annona reticulata L. and Chrysanthemum indicum.

Callistemon citrinus comes out to be one of such bio-insecticides with many therapeutic active constituents, showing appreciable anti-microbial activity and 80-100% larvicidal activity.

These essential oils have the potential to provide efficient and can be used as a cheap, eco-friendly, safer for humans and the environment and also efficient alternative to the chemical larvicides.

These essential oils have the potential to provide efficient and can be used as a cheap, eco-friendly, safer for humans and the environment and also efficient alternative to the chemical larvicides.

The result of the current investigation revealed that the methanol extract of Eclipta prostrata possess good larvicidal activity against Aedes aegypti with maximum larv suicidal repellent and the numbers of the dead larvae were affected by increasing the concentrations of the plant extracts.

Plants are considered as a rich source of bioactive chemicals3 and they may be an alternative source of mosquito control agents.

The present study was designed to screen the effect of mosquito larvicidal and antimicrobial activitiy of protein isolated from matured leaves of Solanum villosum against mosquito immatures and some pathogenic bacteria.

During the last decade, various studies on natural plant products against mosquito vectors indicate them as possible alternatives to synthetic chemical insecticides3-12.

The results suggest that the leaf methanol extract of S.torvum and bark ethyl acetate extract of A. squamosa from Southern India have the potential for use to control mosquitoes and the larvicidal activity against An.

Insecticides of botanical origin may serve as suitable alternative biocontrol techniques in the future because they are poorly characterized and active principals are not determined and most of the works are restricted to preliminary screening.

An intensive search for new products that are environmentally safe, targetspecific and degradable are demanded to address steadily growing problems of enhancing resistance of mosquito population to synthetic insecticides, pollution of environment and adverse effects on the non-target flora and fauna inhabiting the same aquatic habitat.

Several botanicals offer great promise as sources of phytochemicals for the control of mosquitoes, and one of the earliest reports of the use of plant extracts against mosquito larvae is extraction of plant alkaloids from the Russian weed in 1933.
