“…gambiae larvae which possibly suggest that the highest concentration get to the target site of the larvae very fast to initiate larvicidal efficacy of C. chinensis powder. This is in accordance with the finding by Abok et al [14] in a study on Hyptis suaveolens extract exhibits larvicidal activity against Anopheles gambiae larvae at the highest concentration. Knockdown was not recorded however for Cx.…”

“…gambiae larvae in relation to the treatments after 72 hours exposure period possibly suggests time is a determining factor that should be considered to achieve a good susceptibility profile. This agrees with the findings by Abok et al and Odey [14,31] who showed that exposure duration played a major role in determining the resistance/susceptibility profiles in mosquitoes. After 24-hour exposure period, the larvae of An.…”

“…The failure in current control measures and the growing insecticide resistance is necessitating the search for newer and more effective control strategies [12]. The use of botanicals (plant-based products) is one of the best alternatives to synthetic insecticides [13,14]. This is because they offer a more environmentally friendly method of mosquito control [15] in that they have very weak adverse effect on non-target subjects [16] and are easily biodegradable [17].…”

Mosquitoes spread more diseases than other known arthropod and have shown resistance to conventional insecticides despite several control efforts, prompting the need to explore alternative control measures such as the use of bio-larvicides which are environmentally friendly. To this end, a study on larvicidal activity of the powder of Capsicum chinensis against mosquitoes larvae in Lafia Local Government Area, Nasarawa State, Nigeria was carried out through collection of wild field mosquitoes larvae from April to July 2018. Fresh Capsicum chinensis fruits were collected from farmlands and dried under room temperature and further processed to fine powder from which varying concentrations were used against the larvae. The larvae were exposed at 24, 48 and 72 hours, respectively. Anopheles gambiae larvae were susceptible (100% mortality) to the various concentrations of the powder at the end of the 72 hours exposure period while Culex quinquefasciatus were resistant (0% mortality). There was a very high significant difference (P < 0.0001) in mortality rate of An. gambiae larvae in relation to concentrations while there was no significant difference (P = 1) in mortality rate of Cx. quinquefasciatus across concentrations. LD 50 and LD 90 values for An. gambiae at 24 hours were 21.88mg/ mL and 52.48mg/mL respectively; 16.98mg/mL and 38.90mg/mL respectively at 48 hours and 13.80mg/mL and 30.19mg/mL respectively ay 72 hours. This study shows that Capsicum chinensis is a promising bio-larvicide for controlling An. gambiae. Also, Cx. quinquefasciatus may possibly require higher multiple doses of Capsicum chinensis to influence mortality.

Mesosphaerum suaveolens (L.) Kuntze is a species widely used traditionally in the treatment of ailments, such as stomach pain, hemorrhoids, cough, verminosis, ulcer, liver disease, fever, influenza, nasal congestion, and inflammation. This review aims to provide a survey of available information on seven international electronic databases (Google Scholar, Medline, ResearchGate, Web of Science, Scopus, Science Direct, and PubMed) about botanical aspects, traditional uses, phytochemistry, and biological activities of M. suaveolens. Mesosphaerum suaveolens is a tropical America native species, but it can be found in several parts of the world as a ruderal plant. The species is the most studied species of the genus Lamiaceae due its phytochemical aspect, especially regarding the chemical composition of its essential oil. Besides the essential oils, M. suaveolens is a source of numerous secondary compounds such as triterpenes, diterpenes, and phenolic compounds, which are related to its biological activities, such as allelopathic, antibacterial, antifungal, insecticidal, and larvicidal activities as described in the literature.
