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

open access: yesPest 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

open access: yesPest 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 ...

Absorption and translocation of 14C‐propiconazole associated with two adjuvants in young coffee plants

open access: yesPest Management Science, EarlyView.
Experimental workflow evaluating 14C‐propiconazole absorption and translocation in Coffea arabica with two biodegradable adjuvants, quantified at six post‐application time points using radioscanner and liquid scintillation spectrometry. Abstract BACKGROUND This study evaluated the absorption, translocation and distribution of 14C‐propiconazole applied ...

Economics of Pre-Plant, Topdress, and Variable Rate Nitrogen Application in Winter Wheat [PDF]

open access: yes
Past research about the efficiency of nitrogen application in winter wheat (Triticum aestivum L.) based on source and timing has produced inconsistent results. The majority of the literature used data from few locations over short time periods.

Epidemiological drivers of turnip yellows virus and its vector Myzus persicae in Australian canola (Brassica napus) systems: a 3‐year study of commercial crops and noncrop vegetation

open access: yesPest Management Science, EarlyView.
A 3‐year study across southern Australia aimed to characterize drivers of infection in the Myzus persicae–turnip yellows virus–Brassica napus pathosystem. Identification of key reservoir hosts and the strong association between earlier sowing and increased disease incidence highlight opportunities for targeted weed management, strategic sowing ...

In planta fluxapyroxad gradients from seed treatment differentially select fungicide‐sensitive and reduced‐sensitive genotypes of Pyrenophora teres f. maculata

open access: yesPest Management Science, EarlyView.
Spatial concentration gradients of seed‐applied fluxapyroxad within barley create heterogeneous exposure environments, driving differential suppression of succinate dehydrogenase inhibitor‐sensitive Pyrenophora teres f. maculata isolates and enrichment of reduced‐sensitive genotypes, thereby shaping within‐host fungicide resistance selection dynamics ...

Pesticide use in integrated pest and pollinator management framework to protect pollinator health

open access: yesPest Management Science, Volume 81, Issue 4, Page 1691-1696, April 2025.
Integrated pest management (IPM) emphasizes non‐chemical methods, with pesticides as a last resort, while integrated pest and pollinator management (IPPM) integrates pollinator health into pest control strategies. Abstract Agricultural pesticides have historically been a critical tool in controlling pests and diseases, preventing widespread suffering ...
