The phenomenon of invasive alien species has become one of the greatest threats to the biological diversity of the planet, placing major constraints on development. In order to provide the tools needed to address this pervasive issue, the current knowledge on invasive species must be further...

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. The above mentioned oils were used at a concentration of 0.02, 0.05...

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...

1,2-Dehydropyrrolizidine alkaloids (PAs), known to be nematotoxic in vitro, represent a class of secondary plant metabolites from hundreds of plant species worldwide. Pot experiments with the commercially available PA-containing plants Ageratum houstonianum, Borago officinalis, Senecio bicolor, and ...

Phragmidium violaceum causes leaf rust on the European blackberry (Rubus fruticosus L. aggregate). Multiple strains of this pathogen have been introduced into southern Australia for the biological control of at least 15 taxa of European blackberry, a nonindigenous, invasive plant. In climates...

Cotton farmers in the Mediterranean region, Turkey, have used synthetic insecticides against the cotton aphid for many decades. The plant extracts (California pepper tree, Schinus molle and red gum, Eucalyptus camaldulensis) and neem clearly reduced adult longevity, survival rate, fecundity, and...

Of the many exotic plants that have become naturalized in North America, only a small proportion are pests capable of invading and dominating intact natural communities. In the present study, we tested the hypothesis that the most invasive plants are phytochemically unique in their new habitats. A...

Neem oil microemulsion showed a significantly superior bioefficacy than its macroemulsion against Spodoptera litura, Spilarctia obliqua and Euproctis lunata. The IC₅₀ values for inhibiting adult emergence in case of micro- and macroemulsions were 0.09 and 0.14% against Spodoptera litura; 0.07 and...

The main objective of this research is to evaluate the molluscicide activity of Physalis angulata L. Biomphalaria tenagophila specimens under laboratory conditions. Extracts and fractions were supplied by the Laboratório de Química de Produtos Naturais, Farmanguinhos-Fiocruz. Experiments were...

Topical treatment of dogs naturally infected with Demodex canis with the herbal ectoparasiticide AV/EPP/14, containing extracts of Acorus calamus, Azadirachta indica, Pongamia glabra [Pongamia pinnata], Cedrus deodara and Eucalyptus globulus at 1:4 concentration showed good acaricidal action. The...
