“…Indeed, neem-based biopecticides contain azadirachtin, a molecule capable of disrupting the morphogenesis and embryonic development of insects [12]. Our results have been correlated with those of [13] and [14] in which the use of biopesticide has reduced the proliferation of insects and during cabbage and rice conservation.…”

The conservation of cola nuts (Cola nitida) poses a real problem in Côte d'Ivoire because of the post-harvest losses. The objective of this study was to evaluate the impact of post-harvest technologies on organoleptic and physical properties of cola nut during storage. A biopesticide, glucose syrup and biopesticide + glucose syrup were applied to fresh cola nuts before conditioning and kept at 28˚C for 6 weeks. Physicochemical and sensory analyses were performed to check the quality of the nuts during storage. The results showed that the biopesticide keep cola nuts better than the others methods with only 11.66% ± 3.04% and 13.66% ± 3.95% of loss rates for white and red cola nuts respectively. Cola nuts treated with bio-pesticide retain significantly their freshness with 62.00% ± 1.15% of moisture for white nuts and 64.00% ± 2.00% of moisture for red nuts compared to those treated with glucose syrup and bio-pesticide + glucose syrup (56.66% ± 1.15%). Cola nuts treated with biopesticide have a better acceptability compared to those subjected to others treatments. The use of biopesticide for the storage of cola nuts minimizes the losses and maintains the quality whatever the type of cola.

“…Ceci se confirme bien par le faible taux d'attaque des feuilles et le faible niveau de défoliation de la surface foliaire relativement observés au champ. Les produits à base de neem inhibent en effet la prise de nourriture et la croissance des insectes appartenant à différents d'insectes (Nathan et al, 2007;Schenk et al, 2001 ;Mondedji et al, 2014). Nos résultats sont en accord avec ceux de Gnago et al (2010) qui ont rapporté que les extraits de graines de neem réduisaient la densité des populations d es altises du gombo.…”

“…Par ailleurs, le coût élevé des insecticides chimiques de synthèse les rend inaccessibles aux paysans africains et appellent à la recherche de solutions alternatives pour limiter l'attaque des insectes. Des biopesticides à base de plantes à effet insecticides comme le neem (Nguema Ndoutoumou et al, 2015 ;Mondedji et al, 2016) et des champignons entomopathogènes dont Beauveria bassiana sont de plus en plus utilisés dans les luttes contre les ravageurs des cultures (Godonou et al, 2009;James et al, 2009).

Parmi les ravageurs du gombo, Abelmoschus Spp L., les altises, Podagrica Spp (Coleoptera: Chrysomelidae), causent d'importants dommages à la culture. Les fortes infestations de l'insecte réduisent les activités photosynthétiques de la plante, entraînant des pertes élevées de rendement. La présente étude vise à comparer l'effet de deux bioinsecticides, Suneem 1% EC, 10 g/l d'azadirachine (20%), Beauveria bassiana (1 x10 11 spores/ha) et le cyperméthrine 50 EC (1 l / ha), un insecticide de synthèse, pour le contrôle de Podagrica Spp, en conditions de champ. Deux applications des différentes formulations ont été faites à intervalle de 6 jours sur la partie aérienne des plantes. Les résultats ont montré que la cyperméthrine a causé la plus forte réduction de la densité de population des altises (89,56 ± 0,76), suivi de Suneem (81,24 ± 2,40) et du B. bassiana (64,90 ± 3,07). De même le pourcentage des feuilles attaquées et le pourcentage de surface foliaire endommagée par l'insecte ont été significativement affectés par les traitements. Il ressort de cette étude que B. Bassiana et le Suneem, peuvent être utilisés pour lutter efficacement contre les populations d'altises de gombo, Podagrica Spp en condition de champ.

In urban and peri-urban areas in West Africa, the cabbage Brassica oleracea L. (Brassicaceae) is protected using repeated high doses of synthetic insecticides. After a brief description of available IPM components, this paper presents a literature review focused on the botanical extracts that have been experimented with at the laboratory or in the field in West Africa against major cabbage pests. The literature reviewed mentions 19 plant species from 12 families used for cabbage protection in the subregion. The species most used are Azadirachta indica, Capsicum frutescens, Ocimum gratissimum and Ricinus communis. An overview of the world literature showed that a total of 13 plant species belonging to 8 families used to control cabbage pests are reported from the rest of Africa, and 140 plant species belonging to 43 families from the rest of the world. The most commonly used and tested plant species against insect pests in the three geographical areas considered is A. indica.
