TL;DR: Repellent activity of Piper guineense and Xylopia aethiopica fruits oils in liquid paraffin against adult Aedes aegypti in the laboratory showed that repellency is dependent on both the concentration and time after application.
Abstract: Repellent activity of Piper guineense and Xylopia aethiopica fruits oils in liquid paraffin were evaluated against adult Aedes aegypti in the laboratory. Results showed that repellency is dependent on both the concentration and time after application. P. guineense and X. aethiopica oils showed complete protection from mosquito bite for 2h at 35%(v/v) and 30% respectively. The activity of eucalyptus oil (positive control), a commercial repellent, at 30% was only able to protect for 2h. Both oils used could be applied as repellents where protection from mosquito bite is sought for, over a short period of time.

TL;DR: Information collected from traditional healers and breeders revealed that 66 herbaI remedies and 55 medicinal plants are used for the treatment of intestinal helminthiasis in the Ferkessedougou region, in the Northern part of the Cote d'Ivoire.
Abstract: Information collected from traditional healers and breeders revealed that 66 herbaI remedies and 55 medicinal plants are used for the treatment of intestinal helminthiasis in the Ferkessedougou region, in the Northern part of the Cote d'Ivoire. The plants species are divided into 33 families and 53 genera. Leaves, roots and stem barks were most frequently used in the form of decoction, pounded plants and ground remedies. Administration was essentially oral. Based on these results and the literature, 30 plant species belonging to 29 families were selected for in vitro anthelmintic screening, using Haemonchus contortus as the test species. Of 34 crude ethanol extracts tested, 7 were active on the different stage larvae of H. contortus. These are Napoleonaea vogelii followed by Parinari excelsa, Sacoglottis gabonensis, Xylopia aethiopica, Waltheria indica, Ceiba pentandra, Harungana madagascariensis. These results supported the traditional use of these plants in the control of helminthiasis in small ruminants and probably in human.

TL;DR: This study highlights the potentials of crude aqueous extracts of P. guineense and A. melegueta as biopesticides for thrips control on cowpea flowers and indicates that this technology is safe, easy to adopt, environmentally friendly and cheap.
Abstract: The efficacy of crude aqueous extracts of Piper guineense Thonn & Schum, Aframomum melegueta Schum, Xylopia aethiopica (Dunal) A. Richard, Zingiber officinarum L. and Capsicum annum L. was evaluated for the control of legume flower bud thrips on cowpea. These extracts were applied at 10% and sprayed once weekly for four weeks during 1997, 1998 and 1999 cropping seasons. The extracts reduced the population of thrips and gave significant (p < 0.05) protection to cowpea flowers compared to the untreated control during the three years cropping seasons. Pod production was significantly higher (p < 0.01) on plots treated with P. guineense, followed by A. melegueta extracts. This study highlights the potentials of crude aqueous extracts of P. guineense and A. melegueta as biopesticides for thrips control on cowpea flowers. This technology is safe, easy to adopt, environmentally friendly and cheap.

TL;DR: The potential of incorporating P. guineense extract in mixtures with other plant species in the management of M. sjostedti oncowpea flowers to ensure optimum pod load of cowpea is indicated.
Abstract: Insecticidal attributes of aqueous extracts of West African black pepper (Piper guineense Schum and Thonn) seeds mixed at three proportional levels (10:10, 10:20, and 20:10% w/v) with neem (Azadirachta indica A. Juss) seeds, African pepper (Xylopia aethiopica (Dunal) A. Rich.) pods, garlic (Allium sativum L.) bulbs and clove (Syzigium aromaticum (L.) Merr. & Perr.) inflorescence, were evaluated against the flower thrips, Megalurothrips sjostedti Tryb. in two-year field trials. Compared with the other mixture treatments, the mixtures of West African black pepper with garlic bulb at 10:10% and 20:10% w/v were superior (P < 0.05) in reducing the numbers of M. sjostedti in cowpea flowers during the periods. Pod density was significantly (P < 0.05) higher at these mixture proportions compared with the other P. guineense mixtures and was comparable to cypermethrin + dimethoate used as synthetic check. All the plant extracts at different mixture proportions were superior to the untreated control in all ...
