“…Instead, as part of developing an integrated pest management (IPM) program for controlling stored product pests of grains, the impact of plant powders on one of the biocontrol agents, beneficial parasitoids or wasps, was evaluated. A diverse group of plant powders or their EOs from eight families (Apiaceae [ 30 ], Euphorbiaceae [ 25 ], Lamiaceae [ 22 , 31 , 32 , 33 , 34 ], Leguminosae [ 35 ], Myrtaceae [ 21 ], Poaceae [ 22 , 24 ], Solanaceae [ 35 ] and Zingiberaceae [ 23 , 34 ]), adversely affected beneficial parasitoids by increasing adult mortality, reducing the rate of parasitism, repelling the parasitoid, reducing adult longevity and reducing the emergence of the developing parasitoids. This suggests that plant powders may also be efficacious for P. venustus .…”

Developing a bee-friendly alternative to traditional insecticides used within commercial environments can contribute to reductions in pesticide exposure experienced by managed bees. We performed acute contact toxicity studies using fifteen plant powders from seven plant families against a parasitoid pest, Pteromalus venustus, and its host, the Alfalfa leafcutting bee (ALB). Ajwain, cinnamon, clove, cumin, fennel, ginger, nutmeg, oregano and turmeric applied at low contact concentrations had sufficient fumigant properties to cause equivalent or higher parasitoid mortality as that obtained with the traditional insecticide. Nutmeg adversely affected adult ALBs at both low and high contact concentrations, thus eliminating it as a candidate. Increasing the contact concentrations did not consistently increase parasitoid control but did increase adverse effects on the ALBs. In addition, the efficacious plant powders significantly reduced the sexual function and fertility of the female parasitoids, a feature not associated with the traditional insecticide. The dual nature of the mechanisms underlying the effects of the plant powders may translate into effective control of the parasitoid populations in the commercial environment. The results reported here support further evaluations of Ajwain, cinnamon, clove, cumin, fennel, ginger, oregano and turmeric as potential botanical insecticides for control of P. venustus.

“…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)

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)

“…There are no data on thyme oil effects on A. obtectus' natural enemies and common bean seed germination. However, it is known that EOs may have toxic, repellent and reproduction reducing effects on Dinarmus basalis (Rondani), the main parasitoid of A. obtectus [48,49,50]. It is also known that thyme oil and thymol may reduce seed germination of many plant species and that species with larger seeds are less susceptible [51,52].…”

The bean weevil (Acanthoscelides obtectus, Say) is a serious pest of stored bean seeds. Bean weevil control relies heavily on the use of synthetic insecticides. In the search for a sustainable alternative, the residual contact toxicity and anti-oviposition activity of thyme (Thymus vulgaris L.), rosemary (Rosmarinus officinalis L.) and basil (Ocimum basilicum L.) essential oils as well as their dominant components (thymol, α-pinene, 1,8-cineole and linalool) were tested against A. obtectus adults. Out of the seven tested botanicals, T. vulgaris oil, thymol and linalool exhibited the highest toxic potential (>90% mortality). Females were less susceptible than males. The insecticidal activity of these botanicals was much greater when they were applied on glass compared to direct application to the bean. All tested botanicals reduced oviposition by bean weevil females. T. vulgaris oil, thymol and α-pinene also deterred bean weevil oviposition, as revealed by a two-choice test. Our research shows that T. vulgaris oil and thymol are promising and sustainable alternatives to synthetic pesticides for protecting stored beans against the bean weevil.
