Genomic Characterisation of Bidens mottle virus in South Africa and an Assessment of the Impact on Helianthus annuus (Sunflower) in an Open Field Setting

Plant Pathology, Volume 74, Issue 5, Page 1266-1276, June 2025.
RNAseq was used to identify the second natural infection of bidens mottle virus on sunflowers in an open field setting in South Africa and is the first detection of the virus in the country and significantly stunted plant growth and yield. ABSTRACT Sunflower (Helianthus annuus) is an oilseed crop of global economic importance, and South Africa ranks ...

Reduced‐lignin alfalfa production in the water‐limited environments of the US Central Great Plains

Agronomy Journal, Volume 117, Issue 3, May/June 2025.
Abstract Previous studies indicate reduced‐lignin (RL) alfalfa (Medicago sativa L.) cultivars as a more digestible livestock feed option with minimal reductions in biomass than conventional alfalfa cultivars at the same growth stage, allowing for harvest flexibility. However, these findings are derived from environments with adequate moisture. Thus, RL

Discovery and biological characterization of a novel mesoionic insecticide fenmezoditiaz

Pest Management Science, Volume 81, Issue 5, Page 2535-2552, May 2025.
Acetylcholine binding protein (AChBP) from the sea slug Aplysia californica was modified using site‐directed mutagenesis to create an insect‐like binding site enabling structure‐based compound design. Fenmezoditiaz is a systemic insecticide with a broad spectrum, lack of cross‐resistance and an additional tool for integrated pest management and ...

Effects of Organic and Synthetic Fertiliser on Insect Herbivore Populations in Quinoa

Journal of Applied Entomology, Volume 149, Issue 4, Page 515-523, May 2025.
ABSTRACT Fertilisers are used in agriculture to promote crop productivity. There are many nutrient sources in fertilisers, and different sources cause variation in plant defence and pest tolerance. Assessing how pests respond to different types of fertilisers is key to develop integrated pest management programs.

Integrated Pest Management in Pigeonpea: Progress and Prospects

Journal of Applied Entomology, Volume 149, Issue 4, Page 661-681, May 2025.
ABSTRACT Pigeonpea is one of the world's most important grain legume crops. Mostly grown and consumed in India, where it is a staple food, pigeonpea production also occurs elsewhere in Asia, Africa, Latin America and Australia. Despite widespread cultivation and staple food status, pigeonpea yields have barely increased over the last half century.

Bioefficacy of different insecticides on cowpea aphid (Aphis craccivora Koch)

International Journal of Entomological Research, 2019
Aphid (Aphis craccivora Koch) is one of the serious pests of cowpea. Bioefficacy of four insecticides with different concentrations namely Jholmol (125 ml/L), Neemix (2 ml/L), Cannabis extract (100 g/L), Chlorpyrifos 50% EC and Cypermethrin 5% EC (2 ml/L) along with control were evaluated against aphid at Research Station of Agriculture and Forestry ...
