Reduced fitness cost accounts for the stability of a malathion‐resistant heterogeneous duplication haplotype in Ceratitis capitata field populations

open access: yesPest Management Science, EarlyView.
Malathion resistance in Spanish field populations of Ceratitis capitata is associated with a point mutation (R allele) and a heterogeneous duplication (RS haplotype) of the Ccace2 gene. The R allele imposes a higher fitness cost than the RS haplotype under laboratory and field conditions. An evolutionary model supports the stability of the RS haplotype

Identifying resistance‐conferring cytochrome P450s in weeds: experimental strategies and practical considerations

open access: yesPest Management Science, EarlyView.
Identifying resistance‐conferring cytochrome P450s requires integrating weed characterization, gene discovery and functional validation. No single approach is sufficient to distinguish causal resistance genes from herbicide‐metabolizing enzymes. Abstract Cytochrome P450 monooxygenases (P450s) play a pivotal role in metabolic herbicide resistance, yet ...

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 ...

Evaluating larvicide performance against Culicoides sonorensis in semi‐field conditions

open access: yesPest Management Science, EarlyView.
This study evaluated the efficacy of larvicide products against Culicoides sonorensis populations under controlled semi‐field conditions. Larvicide efficacy against C. sonorensis declined over time, in different environmental conditions. In particular, precipitation and habitat disturbance influenced residual performance. Abstract BACKGROUND Culicoides

Reducing copper inputs through integration of essential oil‐based formulations: laboratory and 2‐year vineyard evaluation against Plasmopara viticola

open access: yesPest Management Science, EarlyView.
Combining an essential oil (EO)‐based formulation with copper effectively controls Plasmopara viticola. Field trials showed a 92–99% protection with lower copper inputs, achieving a 45% copper reduction without compromising efficacy. This approach supports EO‐based products as sustainable alternatives for grapevine downy mildew management.
