Plant-derived biopesticides are components of integrated pest management that offer alternatives to conventional synthetic insecticides. In the present study, methanolic extracts of Chromolaena odorata (Asteraceae), Garcinia kola (Clusiaceae), Pueraria montana (Fabaceae), and Taraxacum officinale (Asteraceae) were evaluated against the first instars, the third instars, and adults of the Colorado potato beetle, Leptinotarsa decemlineata, in no-choice […]

Insecticides /

Cultivated potato, Solanum tuberosum (Solanaceae), is a key host of the Colorado potato beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae). This important defoliating pest is recalcitrantly resistant to multiple classes of synthetic insecticides when overused. Hence, there is a continual search for novel active ingredients, such as biopesticides, which hold promise but are poorly explored. Here, variable

Vernonia amygdalina Delile (Asteraceae), commonly known as bitter leaf, is a tropical shrub that may potentially serve as a biopesticide against the Colorado potato beetle Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae), a key pest of potatoes. The beetle’s behavioral response to the methanolic leaf extract of V. amygdalina was evaluated in this study. Using no-choice, dual-choice, and wind-tunnel assays under laboratory

Insecticides /

BACKGROUND: The Colorado potato beetle (CPB), Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae), is as important pest of potato, Solanum tuberosum, in the U.S. CPB management is heavily dependent on broad-spectrum insecticides, thereby stimulating an interest to identify alternative solutions. In this study, we evaluated the efficacy of ledprona, a dsRNA interference-based bioinsecticide, following different application timings

Insecticides, Microevolution /

The Colorado potato beetle (CPB) is the primary defoliator of potatoes and is notorious for its ability to develop resistance to various insecticides. This remarkable adaptability may partly reflect selective pressures imposed due to the beetle’s coevolution with toxic Solanaceous host plants. As the initial interface between the environment and the insect olfactory system, odorant-binding

Insecticides, Microevolution /

RNA-based bioinsecticides that comprise a dsRNA active ingredient and function by RNA interference (RNAi) are being commercialised as insecticidal traits in transgeniccrops and as sprayable biopesticides. These RNAi insecticidal technologies are valuable alternatives to conventional chemical insecticides due to their efficacy, high degree ofspecificity and favourable human and environmental safety profiles. As with all pesticides,

Insecticides, Microevolution, Reviews

Everywhere, pests and pathogens evolve resistance to our control efforts, impairing human health and welfare. Developing sustainable solutions to this problem requires working with evolved immune and ecological systems, rather than against these evolutionary forces. We advocate a transdisciplinary approach to resistance based on an evolutionary foundation informed by the concepts of integrated pest management

American Journal of Potato Research 102: 129-151.

Abundance Factors, Insecticides /

Management of the Colorado potato beetle (Leptinotarsa decemlineata) is reliant on conventional insecticides that can negatively affect non-target arthropods. Calantha™ (active ingredient: ledprona) is a sprayable double-stranded RNA biopesticide specific for L decemlineata proteasome subunit beta 5 gene that triggers the RNA-interference pathway and is designed to have limited non-target effects. To test this hypothesis,

Insecticides, Microevolution /

Biopesticides based on RNA interference (RNAi) took a major step forward with the first registration of a sprayable RNAi product, which targets the world’s most damaging potato pest. Proactive resistance management is needed to delay the evolution of resistance by pests and sustain the efficacy of RNAi biopesticides.
