Development and deployment of a risk assessment index as a decision‐support tool for managing whitefly‐transmitted viruses affecting squash

Pest Management Science, EarlyView.
A data‐driven framework identified planting date and row cover as dominant drivers of whitefly‐transmitted virus complex (WTVC) risk in squash. Integration into the SquashRx mobile application enables real‐time risk assessment and supports improved decision‐making for integrated pest management.

Host resistance modulates in planta efficacy of seed‐applied fluxapyroxad against spot form net blotch in barley

Pest Management Science, EarlyView.
Barley variety influences fluxapyroxad efficacy by affecting distribution and dissipation of the active ingredient, with plant biomass contributing to these differences. Abstract BACKGROUND Seed‐applied fungicides are used to protect barley seedlings from spot form net blotch, caused by Pyrenophora teres f. maculata, among other diseases.

Methomyl resistance in Dalbulus maidis (Hemiptera: Cicadellidae): selection, inheritance and multiple‐resistance

Pest Management Science, EarlyView.
The inheritance of methomyl resistance in Dalbulus maidis is autosomal, incompletely dominant and polygenic. No cross‐resistance was found between methomyl and chlorfenapyr, cyantraniliprole and isocycloseram. Abstract BACKGROUND Acetylcholinesterase (AChE) inhibitor insecticides have been important tools for the management of Dalbulus maidis in Brazil;

Chlorantraniliprole: bioactivation in coffee seedlings and control of resistant Leucoptera coffeella populations

Pest Management Science, EarlyView.
Chlorantraniliprole enhanced growth and biomass in coffee seedlings infested by susceptible Leucoptera coffeella, while resistant populations limited its insecticidal performance. These findings emphasize both the bioactivator potential of chlorantraniliprole and the challenges of managing resistance in coffee leaf miner control.

Integrating bioassays and transcriptomics to detect neonicotinoid resistance in Australian Bemisia tabaci MEAM1

Pest Management Science, EarlyView.
The Bemisia tabaci MEAM1 strain GR15‐1R shows partial resistance to neonicotinoids (bottom), which correlates with an increased expression of the P450 gene CYP6CM1 compared to the insecticide‐susceptible strain SU07‐1 (top). Abstract BACKGROUND Bemisia tabaci MEAM1 is a highly invasive and polyphagous pest species of agricultural and horticultural ...
