Effects ofHyptis spicigeraLam. (Labiatae) on the behaviour and development ofCallosobruchus maculatusF. (Coleoptera: Bruchidae), a pest of stored cowpeas

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

“…It was evident that at the lowest dose the essential Data tested by applying the v 2 -test (with Yates correction); for each dose, values are means of four replicates, each set-up with 10 adults; total number of insects for each concentration was 40; Tr treated half, Un untreated half, SE standard error, v 2 r overall v 2 , ** significantly different at P \ 1%, * significantly different at P \ 5% a Doses are expressed as ll of oil per cm 2 of treated filter paper oil of H. spicigera exhibited a higher repellent effect in comparison to H. suaveolens. This result confirms data reported by Sanon et al (2006b) on the repellent and lethal effect of powder and essential oil of H. spicigera against C. maculatus adults. Moreover, our data are also in agreement with the results published by Othira et al (2009) in which it was reported that both the whole H. spicigera plant and the steam-distilled essential oil exhibited strong insect repellent activity at low doses against S. zeamais and T. castaneum.…”

“…Plants of the Hyptis genus, which included more than 400 species, are highly aromatic and are found in the tropical regions of the world (mainly in Africa and America). In West Africa, farmers traditionally introduce Hyptis spicigera Lamarck leaves in their granaries to protect cowpea seeds against bruchids damages (Sanon et al 2006b), while the essential oil obtained by hydrodistillation from the aerial parts of H. verticillata Jacquart exhibited chemosterilant activities against the cattle tick Boophilus microplus Canestrini (Acarina: Ixodidae) and toxic action against adult of Cylas formicarius elegantulus (Summers) (Coleoptera: Brentidae), the most destructive pest of sweet potato (Facey et al 2005). Investigations have shown that other species of this genus, such as Hyptis suaveolens (L.) Poiteau and the above-mentioned H. spicigera, possess valid insecticidal properties (Peerzada 1997;Facey et al 2005;Othira et al 2009) but also that the chemical composition of the extracted oils and their biological activity change as a function of the origin and collecting period of the plants (Onayade et al 1990;Kini et al 1993;Belanger et al 1994;Jirovetz et al 2000;Sidibe et al 2001;Tchoumbougang et al 2005;Noudjou et al 2007).…”

Larvicidal Activity of Essential Oils From Brazilian Croton Species Against Aedes Aegypti L

“…Furthermore, H. suaveolens plant products demonstrated noticeable repellent activity against C. maculatus females, as demonstrated with other insect species (Sanon et al 2006;Ilboudo et al 2010;Benelli et al 2012). However, products from this plant species can cause detrimental effects on natural enemies in storage environments (Sanon et al 2011), thus requiring caution when used as grain protectants.…”

“…Plant powders of S. occidentalis caused significant mortality in C. maculatus (Adesina et al 2011), and insecticidal properties of A. pyrifolium (Torres et al 2006), C. sonderianus Lima et al 2006Lima et al , 2013, A. cearensis (Farias et al 2010;Souza et al 2011), and Z. joazeiro (Souza et al 2011) have been documented in different insect species. The repellent activities of Caatinga plant powders need further study although the repellency of many other plant powders against stored pests has been reported (Elhag 2000;Kéita et al 2001;Mazzonetto & Vendramin 2003;Silva-Aguayo et al 2005;Sanon et al 2006;Kabir & Muhammad 2010).…”
