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 […]

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

Pleiotropic functions of an antenna-specific odorant binding protein linking xenobiotic adaptation and olfaction in the Colorado potato beetle, Leptinotarsa decemlineata. Insects 16(12), 1259.

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,

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

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,

Integrated pest management (IPM) is an educated and systematic effort to use multiple control techniques to reduce pest damage to economically acceptable levels while minimizing negative environmental impacts. Although its benefits are widely acknowledged, IPM is not universally practiced by farmers. Potato farming, which produces one of the most important staple crops in the world,

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.

Insect Husbandry /

The accumulation of cull potato piles is a concern because they take up space and harbor potato-associated pathogens. Black soldier fly, Hermetia illucens, larvae are an increasingly popular agent for converting organic wastes into ingredients for animal feeds. In this investigation, their ability to process cull potato waste was assessed. Potato tubers were suitable for
