“…The insecticidal efficacy of A. indica (Neem), H. spicigera and V. heterophylla is no longer in doubtful (Tamgno et al, 2014, Goudoum et al, 2015, Ngamo et al, 2016, Kouninki et al, 2017 and these plants are presented as important sources of botanical pesticides. The differences between the insecticidal activities of the powders of single and combination of plants alone are explained by the composition and the chemical nature of the compounds assets they contain.…”

The red flour weevil, Tribolium castaneum (Herbst 1797) is a pervasive pest, polyphagous which is becoming increasingly resistant to the normal insecticides. Finding alternative insecticides to those because of their inefficiency pollute the environment and poison consumers is an emergency. An ethno-botanical survey conducted with about 300 farmers in the Far North region of Cameroon identified 15 local plants insecticides associated with food during storage in combination with two or three others. Among these plants, the most used are Hyptis spicigera (Lamiaceae) 78%, Azadirachta indica (Meliaceae) 76.6% and Vepris heterophylla (Rutaceae) 28,33% which is more used in mountain area. The powders of these single plants are insecticides on T. castaneum, however A. indica single or in combination with H. spicigera gives better insecticidal efficacy 73.33% and 66.67% mortality respectively.

“…In the same vein, the volatile constituents of the dried powdered leaf essential oil from the same plant revealed the presence of thymol (3.7%), terpineolene (8.2%), fenchone (18.3%), piperitone epoxide (17.7%), piperitone oxide (8.9%), piperitone (1.2%), diosphenol (2.5%) and cis-piperitone (19.5%) (Nukenine et al, 2007). Goudoum et al (2012) analysis showed 15 compounds with highest rate of Fenchone (29.8%) and α-terpinolene (28.3%). Tatsadjieu et al (2008) found 23 compounds among which the main constituents were found to be β-thujone (30.8%), terpinolene (25.2%) and piperitenone oxide (10.9%).…”

“…Previous works in Cameroon showed the richness of the two plant materials in volatile constituents quantitatively and qualitatively (Nukenine et al, 2007;Goudoum et al, 2012;Praveen et al, 2012). These phytoconstituents may be responsible for the mosquito larvicidal and pupicidal potentials claimed in this study.…”

Objective: To determine the mosquito larvicidal and pupicidal activities of Cameroonian Plectranthus glandulosus and Callistemon rigidus leaf essential oils against 4 th instar larvae and early pupae of Anopheles gambiae, Aedes aegypti and Culex quinquefasciatus. Methods Conclusion:These results suggest that the Cameroonian P. glandulosus and C. rigidus leaf essential oils can be used as an ideal eco-friendly approach which may replace DDVP, the synthetic chemical, for vector control programs.

“…The increasing levels of FFA and acid values were caused by the increased activity of the lipase enzyme in CPO. In addition, in impure (nonrefining) state, FFA undergoes an autoxidation process to produce primary oxidation products (peroxides and dienes) and secondary derivatives (carbonyls, aldehydes, trienes) (Goudoum et al, 2017). (Chong, 2012).…”

The present study aimed to determine the effectiveness of adding natural antioxidants from ethanolic extract of mango parasite (Dendrophthoe petandra) to oxidation stability of crude palm oil (CPO) during storage. The parameters tested were levels of free fatty acid (FFA), acid values, and deterioration of bleachability index (DOBI). The antioxidant activity of D. petandra extract obtained was IC50 of 6.369 ppm. Concentrations of D. petandra extract range from 200 to 1000 ppm. Based on the results, the ethanolic extract of D. petandra was able to reduce the FFA and acid value and increase the DOBI compared to the negative control. The lowest FFA levels and acid numbers were obtained from samples with addition of 1000 ppm natural antioxidants with FFA of 4.2% and acid value of 7.4 mg KOH/g, while the DOBI value increased to 1.300.
