The efficacy of synthetic inorganic insecticides to control malaria vector mosquitoes is compromised by increased mosquito resistance to insecticides. Furthermore, use of inorganic insecticides raises serious environmental toxicity concerns. The test plants, Oreosyce africana and Piper capense were identified in Ethiopia through ethnobotanical leads obtained on the basis formal and informal fie...

Taxonomic notes: Preliminary genetic evidence suggests that there may be at least two species of African Elephant, namely the Savannah Elephant (Loxodonta africana) and the Forest Elephant (Loxodonta cyclotis) (Roca et al. 2001, 2005). A third species, the West African Elephant, has also been postulated. The IUCN SSC African Elephant Specialist Group currently accepts the single species proposa...

The effects of K. africana fruit (Lam. Benth), family bignoniaceae, were investigated on the sperm quality of C. gariepinus, (mean body weight, 396.05±7.04). Five diets with crude protein of 40% were formulated with different inclusion levels of K. africana powder. D1 (control) has 0 g/kg of the powder, while D2, D3, D4 and D5 has 50, 100, 150 and 200 g/kg of the K. africana powder. A total of ...

Herbivory in some Nicotiana species is known to induce alkaloid production. This study examined herbivore-induced defenses in the nornicotine-rich African tobacco N. africana, the only Nicotiana species indigenous to Africa. We tested the predictions that: 1) N. africana will have high constitutive levels of leaf, flower and nectar alkaloids; 2) leaf herbivory by the African bollworm Helicoverp...

Conservation priorities for Prunus africana, a tree species found across Afromontane regions, which is of great commercial interest internationally and of local value for rural communities, were defined with the aid of spatial analyses applied to a set of georeferenced molecular marker data (chloroplast and nuclear microsatellites) from 32 populations in 9 African countries. Two approaches for ...

Proximate composition and phytochemical constituents of stems of A. africana and T. diversifolia (Asteraceae) were investigated. The stems of these species contain anti-oxidant, anticancer, anti-tumor, anti-viral, anti-inflammatory and anti-allergic properties which cures malaria, skin diseases, athlete’s foot, asthma, gonorrhoea and to stop bleeding. The stems of these two species revealed the...

Isolates of Claviceps causing ergot on sorghum in India were analysed by AFLP analysis, and by analysis of DNA sequences of the EF-1alpha gene intron 4 and beta-tubulin gene intron 3 region. Of 89 isolates assayed from six states in India, four were determined to be C. sorghi, and the rest C. africana. A relatively low level of genetic diversity was observed within the Indian C. africana popula...

background & aim: mammea africana sabine (guttiferae) stembark commonly used traditionally to treat various diseases and ailments was evaluated for nephroprotective activity against paracetamol – induced kidney injury in rats to confirm its use in the treatment of kidney diseases. experimental:  the nephroprotective effect of the extract was evaluated by the determination of some kidney fun...
