“…Earlier studies confirmed the insecticidal effects of these plants species: B. ferruginea [45]; B. sapida [15,36,[50][51][52][53]; and K. senegalensis [54][55][56][57][58][59]. Acetone extract of K. senegalensis showed the lowest LC 50 and the biggest toxicity ratio, consequently the most toxic on D. porcellus.…”

“…Acetone extract of K. senegalensis showed the lowest LC 50 and the biggest toxicity ratio, consequently the most toxic on D. porcellus. Some studies proved efficacy of K. senegalensis for controlling stored products insects such as Trogoderma granarium [59], Callosobruchus maculatus [54,55], and Tribolium confusum [58]. The phytoconstituents found in the leaf extract of K. senegalensis include tannins, saponins, flavonoids, steroids, and alkaloids [37].…”

Dinoderus porcellus is considered as the most important pest of stored yam chips and compounds extracted from plants can be used for its control. The present study aimed to test the insecticidal and repellent activities of powders and extracts of leaves of Bridelia ferruginea, Blighia sapida, and Khaya senegalensis against D. porcellus. The efficacy of plant powders was compared with the synthetic pesticide Antouka (Permethrin 3 g/kg + pirimiphos 16 g/kg). The results of the experiment revealed that all plant powders were effective as repellents. Antouka was more effective as insecticidal than the plant powders and minimal weight loss was observed with B. sapida at 2%. Among treatments, propanol extract of K. senegalensis at 5% was found to elicit the highest repellent effect on D. porcellus. The LC 50 results revealed that the acetone extract of K. senegalensis is the most toxic (0.29 L/insect) to the pest, while the propanol extract of B. ferruginea at 5% exhibited strong fumigant toxicity against D. porcellus, with 88.89% of pest mortality at 160 L/L air. The findings from the current work proved that plant powders and extracts of the three plants are sources of botanical insecticides which may be used in the integrated management of D. porcellus.

“…Other studies report quite different composition of the H. spicigera essential oils (Tchoumbougang et al 2005;Sidibe et al 2001). A relatively recent literature reports that essential oils of H. spicigera and H. suaveolens could be a valid option to chemical insecticides for the control of many stored-food pests (Ngamo et al 2007a, b, c;Othira et al 2009;Sanon et al 2006a;Noudjou et al 2007;Kéïta et al 2000;Raja et al 2005;Iloba and Ekrakene 2006;Sanon et al 2006a, b;Kouninki et al 2007;Ngamo et al 2007a, b;Kossou et al 2007), suggesting the necessity of further investigations.…”

Hyptis suaveolens and Hyptis spicigera (Lamiaceae) essential oils: qualitative analysis, contact toxicity and repellent activity against Sitophilus granarius (L.) (Coleoptera: Dryophthoridae)

et al. 2010

Essential oils from Hyptis suaveolens (L.) Poiteau (Lamiaceae) and Hyptis spicigera Lamarck (Lamiaceae) were first analysed by gas chromatography and by gas chromatography/electron impact mass spectroscopy and then evaluated for toxicity and repellent activity against Sitophilus granarius (L.) (Coleoptera: Dryophthoridae), one of the most serious worldwide stored grain pests. Fifty-six compounds have been identified in the essential oil of H. suaveolens: monoterpene hydrocarbons were the most represented volatiles (64. 1%), followed by sesquiterpene hydrocarbons (24. 0%), oxygenated monoterpenes (8. 1%) and oxygenated sesquiterpenes (2. 4%). Diterpenes and non-terpene derivatives were scarcely represented. Sixty compounds have been identified in the essential oil of H. spicigera: monoterpene hydrocarbons were the most represented class of volatiles (70. 4%), followed by sesquiterpene hydrocarbons (22. 6%). Results from topical applications on insects showed that both essential oils had an effective insecticidal activity. The complete kill of S. granarius was observed 24 h after treatment at a minimum effective dose of 0. 4 and 0. 6 μl per insect with H. suaveolens and H. spicigera oil, respectively. Results from repellency tests showed that the two essential oils had a repellent activity on S. granarius adults: at the lowest dose (2 × 10 -4 μl oil per cm 2), H. spicigera essential oil exhibited a higher repellent effect in comparison to H. suaveolens. No significant differences were observed for the repellent effect between the two essential oils at the highest dose (2 × 10 -2 μl oil per cm 2)

This review provides evidence on the genetic diversity, chemical constituents, and ecotoxicology of Mesosphaerum suaveolens ‘ essential oil. It emphasizes the agricultural benefits such as crop protection effectiveness of the plant and highlights the existing knowledge gaps and research perspectives to promote its utilization in agriculture. A systematic and extensive review of the literature was done and all pertinent full-text articles and abstracts were analyzed and incorporated into the review. Mesosphaerum suaveolens is used traditionally in pharmacology to treat several diseases such as malaria, constipation, stomach problems, and renal inflammation. It also treats cramps, digestive infections, headaches, and skin infections. To date, very few studies have been conducted worldwide about its genetic diversity. These studies highlighted three morphological variants, the blue-flowering, the white-flowering, and the light-purple flowering M. suaveolens. Its wide biological actions may be attributed to the numerous groups of chemical constituents in its essential oil including monoterpenes, sesquiterpenes, and diterpenes. Biological studies highlighted evidence of M. suaveolens being used as an antifungal, bactericidal, antimicrobial, insecticidal, and repellent plant. The essential oil extracted from M. suaveolens showed significant potential for the control of agricultural pests such as Sitiophilus zeamais, Helicoverpa armigera and Helminthosporium oryzae. M. suaveolens is commonly used worldwide as a pesticidal plant in healthcare, agriculture, and food preservation. However, there is a lack of studies concerning the toxicity and effectiveness of isolated potent phytotoxic substances, the efficacy screening in the field, the genetic diversity, the essential oil yield, and productivity. Consequently, further studies are required to fill the knowledge gaps.
