“…Le décocté des feuilles de Detarium microcarpum est utilisé pour soigner les maux de ventre, la carie dentaire, les complications d'accouchement (Kouyaté, 2015). Elles présentent des propriétés antidiarrhéiques et anti-asthéniques (Okolo et al, 2012), antimicrobiennes (Ebi et al, 2011) et larvicides (Adebote et al,2006).…”

Many of the current research interest include the study of molecular antioxidant compounds of natural source. This study aims to evaluate the antioxidant activities of the methanolic extracts of different parts of Detarium microcarpum: trunk and root bark, leaves, fruits and flowers. The total polyphenol content was determined by the Folin-Ciocalteu method and the antioxidant activity by two methods: the free radical scavenging of the DPPH and the Ferric reducing antioxidant power (FRAP) method. The total polyphenol content of plant parts was found to vary from 109.44 to 40.06 mg capacity was found to be highest in the trunk bark (171.71 mole EAA/100mg); root (170.79 mole EAA/100mg) and leaves (127.96 mole EAA/100mg) extracts. The DPPH scavenging capacity showed a significant reduction of the DPPH radical with IC50 inhibitory concentrations ranging from 0.225 to 0.75 mg/ml but still remain low compared to that of Trolox as standard antioxydant. The antioxidant activities of Detarium microcarpum extracts reported in this study could justify the traditional uses of this plant in order to develop new bioactive compounds.

“…Mosquitoes also constitute a very important component in the determinants of insect-borne diseases of public health importance, especially in places where the availability of diverse water bodies support their breeding. The diversities of aquatic habitats for mosquito breeding frequently make them occur in adequate population to constitute biting nuisance or vectors of disease-causing organisms (Adebote, Abolude, Oniye, & Wayas, 2008). An aquatic habitat for oviposition is required by all mosquito species for larval and pupal development.…”

Background: Mosquitoes are known to be notorious for their ability to constitute a nuisance as well as transmit disease-causing organisms (pathogens) to hosts. This study was aimed to determine the species distribution, abundance, and diversity of mosquitoes in Akure South Local Government Area, Ondo State, Nigeria. Results: A total number of 100 sites (20 sites from each location) were randomly sampled in the five locations (Alagbaka, FUTA, Oja-Oba, Ondo road, and Seebi). These larvae were identified to species level using × 20 magnification of a dissecting microscope and identification keys. Thirteen species of mosquitoes including 5 Aedes species, 6 Culex species, and a species of Anopheles and Toxorhynchites belonging to four genera were recorded. The abundance of the four mosquito genera varied significantly (p < 0.05) with Culex having the highest abundance (2151) and Toxorhynchites having the lowest abundance (23). Also, the distribution and abundance of the mosquito species varied significantly (p < 0.05) with Culex andersoni being the most abundant species encountered (709) and Culex striatipes being the least abundant (8). The favorable physico-chemical parameters that favor breeding include pH range of 7.14-7.30, temperature range of 27.3-29°C, electrical conductivity range of 65.6-98.0 μs, and dissolved oxygen range of 2.43-3.84 mg/l. Also, FUTA (1400) and Oja-Oba (994) had higher mosquito abundance than other locations (Alagbaka-124, Seebi-198, and Ondo road-224). Conclusions: The persistent occurrence of Aedes, Culex, and Anopheles species pose a serious epidemiological concern to the inhabitants of Akure South Local Government Area. Therefore, public enlightenment on vector control is of paramount importance.

“…Likewise, 70% (n = 1651) of mosquito immature stages were found in less than 250 ml volume of water. A study done by Adebote et al (2008) shows that Aedes genus of mosquitoes breeds in phytotelmata at significantly smaller water volumes than Culex genus and the abundance of all species of mosquitoes correlated positively and significantly with water volumes in the phytotelmata. Adebote et al (2008) also show that not only the water volume but also the surface area and depth variously affect mosquito species occurrence and abundance.…”

Phytotelmata are used by many insects for breeding. This study was designed to identify mosquito species breed in phytotelmata available in the Kalutara district. A larval survey was carried out once every two months from January 2019 to April 2021 in thirteen Medical Officer of Health (MOH) areas. For each survey, 20 premises including houses, institutions, public places, roadsides, open areas, and plantations were examined in one randomly selected Grama Niladari (GN) division in each MOH area. According to the study, 18 mosquito species belonging to 6 genera were identified in 8 types of phytotelmata namely; tree holes, bamboo stumps, leaf axils, tree trunks, fruit husks, fruit shells, fallen leaves, and fallen spathes. Species richness was highest in tree holes and species diversity was highest in fallen leaves. Similarly, 17 types of coexistence could be observed. The coexistence of four species Aedes chrysolineatus, Ae. downsiomyia, Ae. w-albus, and Ae. krombeini were observed in Dillenia suffruticosa fallen leaves. Species richness and species diversity of mosquitoes that breed in phytotelmata were highest in Walallawita. The correlation between the volume of water in phytotelmata and the number of larvae in the phytotelmata habitat was statistically insignificant. Although phytotelma is a hidden aquatic habitat, this study indicated that it is an important breeding place for a variety of mosquitoes including vector mosquitoes such as Ae. aegypti and Ae. albopictus.
