The rapid spread of highly aggressive arboviruses, parasites, and bacteria along with the development of resistance in the pathogens and parasites, as well as in their arthropod vectors, represents a huge challenge in modern parasitology and tropical medicine. Eco-friendly vector control programs are crucial to fight, besides malaria, the spread of dengue, West Nile, chikungunya, and Zika virus, as well as other arboviruses such as St. Louis encephalitis and Japanese encephalitis. However, research efforts on the control of mosquito vectors are experiencing a serious lack of eco-friendly and highly effective pesticides, as well as the limited success of most biocontrol tools currently applied. Most importantly, a cooperative interface between the two disciplines is still lacking. To face this challenge, we have reviewed a wide number of promising results in the field of green-fabricated pesticides tested against mosquito vectors, outlining several examples of synergy with classic bi...
“Eco-friendly and Economic approach of Green Synthesized Nanoparticles as Aedes Mosquito Control.”
Journal of emerging technologies and innovative research, 2019
World’s 40% population is at risk of dengue which is transmitted by Aedes aegypti and Aedes albopictus. Many measures for Aedes control are taken but still mosquitoes find their way to breed and transmit diseases. Insecticide use is been considered effective for emergency mosquito control and many more insecticides are under trials but mosquitoes usually develop resistance against these chemical formulations. In recent years green synthesized nanoparticles are proved to be potential targets against larvae, pupa and adult form of mosquito. This paper reviews the various developed nanoparticles during and their potentiality in Aedes control. Larvicidal activity of nanoparticles is given for I instars, II instars, III instars, IV instars and pupa differently. Nanoparticles are fabricated from many medicinal plants extract and some are very much effective against mosquito control. This is an eco friendly approach for mosquito control with low risk of resistance development.
Innovative Solution of Nanoscience for Ecofrindly Control of Mosquitoes : Plan for Community Health
Mosquitoes are dreadful insects which are widespread throughout the world. Mosquito bite causes disease like Malaria, Filariasis, Dengue, Zika and Chikungunia. Human filariasis is a main health hazard and common socioeconomic problem in tropical country. Recently Dengue and Chikungunia diseases becoming horrible problem of the world. According to WHO approximately half of the world's population is at risk of Malaria, Dengue and Chikungunia. Overall eradication of mosquito population is impossible; only remedy to avoid mosquito bites. Presently various mosquito control methods are practiced in the world. Chemical mosquito repellents has a amazing safety profile while it contains parathyroid which is proved to be toxic to human causing rashes on skin, brain swelling in children, anaphylactic shock, low BP and eye irritation. Various communities around the world are using chemical pesticide for mosquito control strategies owing to a lack of adequate information. Public awareness and campaigning is necessary in this regard. Communities must boost up the awareness for impediment of ecofrindly mosquito control methods in mosquito-borne illnesses. Community Health care providers must also be erudite about terrible symptom. Present paper focus on formulation of herbal mosquito repellent with nanotechnology and ecofrindly eradication of mosquito population. Herbal mosquito repellents are mostly preferred than chemical mosquito repellents because they are safer and ecofrindly. Some researchers have already noticed that Silver nanoparticles synthesized by using herbal plant leave have tremendous insecticidal properties. The biosynthesis thus resulted and supported by characterization of formulated mosquito repellent with UV photo spectrometer, Transmission Electron Microscope and Scanning Electron Microscope. The mosquito repellency was tested against mosquitoes in captivity. The experiment was carried out during 2013-2016.Perhaps it will be the best solution of nanoscience for ecofrindly control of mosquitoes and best plan for community health.
A Review on Nanoparticles in Mosquito Control - A Green Revolution in Future
Mosquitoes are the potential vectors of many diseases, including malaria, filariasis, dengue, brain fever, etc. There is an urgent need to check the proliferation of the population of vector mosquitoes in order to reduce vector borne diseases by appropriate control methods. Mosquito control is of serious concern in developing countries like India due to the lack of general awareness, development of resistance, and socioeconomic reasons. Nanotechnology, a promising field of research opens up in the present decade and is expected to give major impulses to technical innovations in a variety of industrial sectors in the future. Over the past few decade, nanoparticles of noble metals such as silver exhibited significantly distinct physical, chemical and biological properties from their bulk counterparts. Nano-size particles of less than 100 nm in diameter are currently attracting increasing attention for the wide range of new applications in various fields of industry. Presently, there is a need for increasing the efforts to develop newer and effective methods to control mosquito vectors. The existing chemical and biological methods are not as effective as in earlier period owing to different technical and operational reasons. In particular, this present paper focused on potential role of nanoparticles in mosquito control.
Fungus Generated Novel Nanoparticles: A New Prospective for Mosquito Control
International journal of recent scientific research, 2013
This work was to evaluate the efficacies of the nanoparticles (NPs) of silver (Ag) and Gold (Au) against the major tropical mosquitoes. In the present study, the Ag and Au NPs were synthesized by using the cell free extract of Fusarium oxysporum f.sp. pisi fungus. The bioreduction of AgNPs and AuNPs was monitored by ultraviolet-visible spectroscopy, and the AgNPs and AuNPs obtained were characterized by transmission electron microscopy and scanning electron microscopy. The synthesized AgNPs and AuNPs were spherical particles ranging in size from 20-40 nm (AgNPs) and 2-10 nm (AuNPs). Further, these synthesized NPs were also tasted as larvicides and pupicides against the larvae and pupae of Cx. quinquefasciatus, An. stephensi and Ae. aegypti. The efficacy test was performed at different concentrations for a period of different hours by the probit analysis. The maximum efficacy was observed in synthesized AgNPs against the larvae of Ae. aegypti (LC50 8, 6, 4, LC90 12.30, 12.58, 11.48, ...

Mosquitoes threaten the lives of humans, livestock, pets and wildlife around the globe, due to their ability to vector devastating diseases. Aglaia elaeagnoidea, commonly known as Priyangu, is widely employed in Asian traditional medicine and pest control. Medicinal activities include anti-inflammatory, analgesic, anticancer, and anesthetic actions. Flavaglines, six cyclopenta[b]benzofurans, a cyclopenta[bc]benzopyran, a benzo[b]oxepine, and an aromatic butyrolactone showed antifungal properties, and aglaroxin A and rocaglamide were effective to control moth pests. Here, we determined the larvicidal action of A. elaeagnoidea leaf aqueous extract. Furthermore, we focused on Priyangu-mediated synthesis of Ag nanoparticles toxic to Culex quinquefasciatus, Aedes aegypti and Anopheles stephensi. The plant extract and the nanolarvicide were tested on three mosquito vectors, following the WHO protocol, as well as on three non-target mosquito predators. Priyangu-synthesized Ag nanoparticles...

Dengue is a devastating viral disease transmitted by mosquito vectors of Aedes aegypti and Aedes albopictus. Mosquito populations thrive in favourable breeding conditions, making mosquito control vital. Eliminating larval populations is the most effective method compared with other mosquito control methods. Synthetic chemicals such as organochlorine, organophosphate, carbamate and growth regulators are available for mosquito control, but their use is limited due to health and environmental concerns. Biologically synthesized insecticides are preferable to synthetic insecticides as they are eco-friendly, low cost, target-specific and less toxic for non-target organisms.

Mosquitoes are very obnoxious insects and vectors of many diseases like malaria, filariasis, dengue, yellow fever, encephalitis etc. Among these, malaria is transmitted by Anopheles stephensi mainly in urban areas across the temperate country. So, there is an imperative requirement to imply some mechanisms to reduce the mosquito vector to facilitate the reduction of vector borne diseases throughout the globe. But, mosquito control strategies are now in front of a threat because mosquito populations get resistance against the available synthetic insecticides. Besides the chemical insecticides, several other ways to control the vector population proved unsuccessful in most of the cases. Now, various researchers are trying to develop an alternate effective approach to eradicate malaria from the earth by controlling its vector by using a product which is ecofreindly, cost effective, biodegradable, non-toxic and selective in nature. So, by the amalgamation of the two fields namely the nanotechnology and the vector managements, a new field is now opened up for decades, "the green synthesized nanoparticles as mosquito control agents". The plant-based, fabricated nanoparticles are beneficial over the synthetic one since it is economical, eco-friendly and non-toxic to nature. Silver, gold, zinc, cobalt, copper etc. nanoparticles are green fabricated with different plant parts, fungi as well as bacteria. These nano-materials are of less than 100 nm in diameter and are currently used in various fields of industry. So, adapting the nano-biotechnology to control the mosquito vector is the need of the hour. In this present review we focused on potential role of nano-materials as mosquito control agent against An. stephensi at different life stages of it.
