“…Bio-insecticides, based on the plantessential oils, may represent an alternative to traditional insecticides. In fact, scientific investigations on the effectiveness of essential oils extracted from various spices and herbs demonstrated that they act as contact and fumigant insecticides against stored product pests (Isman 2000;Shaaya et al 1991) and could be evaluated in more detail as potential alternatives (Shaaya et al 1993(Shaaya et al , 1994. Several aromatic plants such as Lamiaceae have traditionally been used in the developing countries to protect stored grain and legumes from pests (Ngamo et al 2007a, b, c).…”

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

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)

“…Very little consideration has been given to the egg stage (Shaaya et al 1993;Ho et al 1997;Huang et al 1997;Tunc et al 2000;Stamopoulos 2002, 2004). As the essential oils are intended to be used like fumigants to disinfest commodities, they should have the ability to kill all stages of insects.…”

Fumigant activity of essential oil vapors distilled from Carum copticum C. B. Clarke and Vitex pseudonegundo Hand I. MZT. was tested against eggs, larvae and adults of Callosobruchus maculatus (F.). Fumigant toxicity was assessed at 27 ± 1°C and 60 ± 5% RH, in dark condition. The influence of different concentrations of the essential oil vapors on egg hatchability, larval and adult mortality was significant. Data probit analysis showed that lethal concentration of the essential oil to kill 50% of the population (LC 50 ) for egg, larvae and adult were found to be 1.01, 2.50 and 0.90 ll/l air of C. copticum oil, followed by 2.20, 8.42 and 9.39 ll/l air essential oil of V. pseudonegundo, respectively. Between these essential oils, C. copticum was almost more toxic than V. pseudo-negundo on all growth stages of C. maculatus. The present study suggests that essential oils from these medicinal plants may be potential grain protectants as botanical alternative fumigants and could be used in the management of various life stages of C. maculatus.

“…The long-lived species would be expected to be more difficult to control, and would require either larger amounts of material or a more persistent compound. Examples of research on edible oils are found in Shaaya et al (1991Shaaya et al ( , 1997, for both long and short-lived beetles infesting several commodities, and in Schoonhoven (1978) against the bruchid Zabrotes subfasciatus (Boheman) infesting beans.…”
