Lantana camara L. is a widespread plant species mostly native to subtropical and tropical regions of the world. In this study, insecticidal and repellent activities of L. camara essential oil were evaluated against Callosobruchus maculatus (Fabricius) (Col: Bruchidae). Analysis of chemical...

The interest in the use of essential oils for insect pest control originates from the need for pesticide products with less negative environmental and health impact than highly effective synthetic pesticides. In the present study, fumigant toxicity of essential oil from Mentha pulegium was assessed ...

Biological activities of eight plant powders including Piptadeniastrum africanum (rootbark), Piptadeniastrum africanum (leaf), Piper guineense, Aristolochia repens, Alstonia boneei, Xylopia aethiopica, Garcinia kola and Picralima nitida were assessed under prevailing atmospheric condition (28±2°C,...

In the present study, 12 pure oxygenated monoterpenes at 2 different doses were tested for their toxicity against second and third instar larvae and adults of three different populations of Colorado potato beetle (Leptinotarsa decemlineata Say). Some of tested compounds were found to be toxic to...

Use of synthetic pesticides in developing countries is not only limited by their being expensive but also the small (uneconomic) fields whose limited production costs cannot offset costs of agricultural implements like agro-chemicals. Subsistence farmers, therefore, have no choice but to use local...

Fumigant toxicity of essential oils from rhizomes of Alpinia conchigera, Zingiber zerumbet, Curcuma zedoaria and their major compounds; camphene, camphor, 1,8-cineole, α-humulene, isoborneol, α-pinene, β-pinene and terpinen-4-ol was investigated with adults of Sitophilus zeamais, Tribolium...

The purpose of the study was to determine influence of natural essential oils, i.e. geranium oil, lavender oil, peppermint oil, pine oil and thyme oil on mortality of foxglove aphid (Aulacorthum solani Kalt.) occurring on tobacco.
