Hydro-distilled essential oil from Kenyan Piper capense (Piperaceae) was analysed by gas chromatography mass spectrometry (GC–MS) and evaluated for larvicidal activity against the malaria vector, Anopheles gambiae. The oil consisted mainly of sesquiterpene hydrocarbons which accounted for 43.9% of the oil. The major sesquiterpenes were δ-cadinene (...
The combined use of morphological and molecular studies allowed for the first time the recognition and description of the adult stage of Clinostomum cutaneum Paperna, 1964 from the grey heron Ardea cinerea L. in Kenya. A redescription of the metacercaria that infect Nile tilapia Oreochromis niloticus niloticus (L.) from the same aquatic environment...
The larvicidal activity of extracts from Aloe turkanensis , Aloe ngongensis and Aloe fibrosa against the common malaria vector, Anopheles gambie , was determined. Ground Aloe leaves from the three plants were sequentially extracted with hexane, ethyl acetate, chloroform, acetone and methanol. Only the ethyl acetate extract of A. turkanensis, hexane...
The European INCO-DEV BOMOSA Project (Integrating BOMOSA cage fish farming systems in
reservoirs, ponds and temporary water bodies in Eastern Africa) intends to establish small scale fish farming in
marginal water bodies in Kenya, Uganda and Ethiopia, creating rural aquaculture networks with the aim to
economically integrate aquaculture with agr...

... Parasite identification was performed by examining the body shape and morphological features of the collected samples and comparing them with those described in the study of Florio et al. (2009) andWu (1995). The modified key of was used to identify the main classification of parasite mature and larvae in the studied fish. ...

... Con los resultados obtenidos es posible sugerir que la especie P. aduncum presenta actividad fungicida contra F. Oxysporum f. sp. vanillae, y ésta se podría extrapolar para el combate contra otros hongos del mismo género y llegar a ser comparable con P. capense, que ha mostrado efecto sobre 16 especies de Fusarium (Matasyoh et al. 2011). ...

... DNA extraction, amplification, and Sanger sequencing were performed by Eurofins Genomics (Ebersberg, Germany). Both Nematoda and Digenea parasites were identified using the nuclear internal transcribed spacer (ITS) rDNA (ITS1, 5.8S, and ITS2) with the same primers 81_f 5′-GTA ACA AGG TTT CCG TAG GTGAA-3′ (Gustinelli et al. 2010) and ITS2.S_r 5′-CCT GGT TAG TTT CTT TTC CTC CGC -3′ (Matthews and Cribb 1998), following Mazzone et al. (2019). For Nematoda, the mitochondrial cytochrome oxidase subunit 1 (COI) marker was also amplified using H7005 5′-ACNACR TAR TANGTR TCR TG-3′ and L6625 5′-TGR TTY TTYGGNCAYCC-3′ primers (Hafner et al. 1994). ...

... The majority of plant extracts with mosquitocidal activities comparable to those of chemical pesticides currently marketed (i.e., with LC 50 values < 30 ppm) were mainly prepared using moderately polar and nonpolar solvents [138,140]. This is the case of (i) petroleum ether extracts of Artemisia annua, Argemone mexicana, Aloe barbadensi, Jatropha curcas, Piper nigrum, Euphorbia tirucalli, Ocimum basilicum, and Piper longum [140][141][142][143], (ii) hexane extracts of Momordica charantia, Khaya senegalensis, Cybistax antisyphilitica, Eucalyptus citriodora, and Solanum nigrum [144][145][146], (iii) carbon tetrachloride extract of Aloe barbadensis [147], (iv) chloroform extracts of Plumbago zeylanica, Plumbago dawei, Plumbago stenophylla, Nyctanthes arbortristis, and Cassia obtusifolia [138,148], (v) methanol extracts of Atlantia monophylla, Ocimum gratissimum, Solenostemma argel, Centella asiatica, Cassia tora, Aristolochia saccata, Annona squamosa, and Chamaecyparis obtuse [149,150], (vi) mixture of chloroform and methanol extracts of Solanum villosum and Cestrum diurnum [151][152][153][154], (vii) ethanol extracts of Azadirachta indica, Ocimum gratissimum, Piper longum, Piper ribesoides, Piper sarmentosum, Annona crassiflora, Annona glabra, Denis spp., Erythrina mulungu, and Eclipta paniculata [138,[155][156][157][158], (viii) benzene extracts of Citrullus vulgaris and Acalypha indica [157][158][159][160], (ix) ethyl acetate extracts of Aloe turkanensis, Solanum nigrum, and Annona squamosa [159][160][161][162], and (x) acetone extract of Ageratum conyzoides [163]. ...
