In tropical and subtropical countries, mosquitoes play vital role as vectors of numerous dangerous diseases, such as dengue, yellow fever, filariasis, malaria, and zika, among others. Aedes albopictus, the Asian tiger mosquito can transmit the viruses of several life threatening diseases including, dengue, yellow fever, and zika. The present study aimed at assessment of the larvicidal activity of the crude extract of Diospyros montana leaves against Ae. Albopictus, and identification of the plant compound and functional groups responsible for larvicidal efficacy via FT-IR and different phytochemical analysis. Effect on the non-target organisms was also evaluated. However, more than 80% larval mortality is observed after 72 hours of exposure in all instars. After 72 hours of exposure, the LC50 caused moderate mortality of 12% and 8% against Chironomus circumdatus and Toxorhynchites splendens respectively. Numerous secondary metabolites, including terpenoids, saponins, flavonoids, and alkaloids, coumarins were present in the crude extract of D. Montana. This is the first study to examine the efficacy of D. Montana leaf extract as a larvicidal agent against Ae. albopictus through determination of its secondary metabolites.

“…As an alternative to synthetic mosquitocides, attempts are now being made to control the mosquito population using plant-derived compounds and phytochemicals that have effective mosquitocidal characteristics. Secondary metabolites in these natural products have larvicidal [ 7 ], pupicidal [ 8 ], adulticidal [ 9 ], repellent [ 10 ] and oviposition deterrence [ 11 ] effects on mosquitoes. These plant-based remedies are biodegradable, environment friendly, less damaging to non-target species, and relatively inexpensive [ 12 ].…”

Mosquitoes are notorious insects that transmit a wide range of infectious diseases, including zika, malaria, chikungunya, filariasis, and dengue. The overuse and incorrect application of synthetic pesticides to control mosquitoes has resulted in resistance development and environmental contamination, both of which have had a negative impact on human health. To address this issue, the larvicidal and pupicidal potential of acetone extract from Casearia tomentosa fruits was investigated. The extract was evaluated in a lab setting against all larval instars and pupa of Culex quinquefasciatus and Aedes albopictus, as well as against third instar larvae in a semi-field condition. Purified compounds through TLC were also tested against 3rd instar larvae of both mosquito and non-target organisms. The FT-IR and GC-MS analyses were used to characterise the extract. Morphological aberration caused by the acetone extract was observed using FESEM. The anal gills and respiratory siphon of both mosquitoes showed significant deformation from their normal state. 100 ppm was found to cause 100% larval mortality at 24 h of exposure in case of Cx. quinquefasciatus and at 72 h of exposure in Ae. albopictus larvae. After 72 h of exposure under in vitro conditions, the extract demonstrated considerable larvicidal activity with LC50 values of 38.33 and 47.56 against 3rd instar larvae of Culex quinquefasciatus and Aedes albopictus, respectively. The acetone extract can be considered as a highly effective mosquito larvicidal agent that is safe for the environment. Graphical abstract

“…Therefore, the present need is to investigate a novel mosquitocide that would be biodegradable, target specific and non-detrimental to any other life forms [8] though some biocontrol agents are reported to reduce mosquito population [9][10][11] . Usually, some of the plant derived molecules are known to have such qualities that proclaim them to be most suitable to formulate mosquito larvicide [12,13] , pupicide [14] , adulticide [15] and repellents [16] along with other attributes like antibacterials [17] , anthelmintics [18,19] etc. Originating from South and Southeast Asia, Michelia champaca L. is a tall, evergreen tree that is mostly cultivated for its lumber.…”

Vector control is in risk as a result of the advent of synthetic pesticide resistance. Plant derived insecticides may be used as future bio control alternatives due to their target specificity and biodegradability. The aim of the present study was to determine the efficacy of Chloroform: Methanolic extract of Michelia champaca seeds against all the larval instars of Culex quinquifasciatus, the vector of Bancroftian filariasis. Chloroform: Methanolic extract showed remarkable larvicidal properties with LC50 and LC90 values as low as 15.33 ppm and 29.77 ppm recorded against the first instar larvae after 72 hours of treatment. There was a clear dose dependent increment in the death rate, which was positively correlated with the solvent concentration and had regression coefficient values close to 1. Because the investigated non-target organisms were unaffected, the plant-based mosquitocide that was thus discovered was proved to be environment friendly. FTIR analysis revealed the presence of various functional groups in the TLC fraction such as alcohol, alkane, methyl group, amine, aromatics, carboxylic acid and ether. So, M. champaca seeds extract can be proclaimed as an outstanding larvicidal agent against Cx. quinquifasciatus, and can serve as a source of potent mosquito larvicide in the near future.
