Mating history shapes Wolbachia‐induced cytoplasmic incompatibility and female fitness in an insect pest

open access: yesPest Management Science, EarlyView.
Mating order and remating of females by males with different endosymbiont associations strongly shape Wolbachia‐induced cytoplasmic incompatibility, female fitness and offspring sex ratio. An incompatible first mating was weakly affected if followed by a compatible mating and vice versa, indicating strong first‐male sperm precedence with consequences ...

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 ...

UV mutagenesis‐enhanced Streptomyces nogalater produces a novel streptothricin‐like compound with strong activity against cabbage soft rot

open access: yesPest Management Science, EarlyView.
UV mutagenesis of Streptomyces sp. KRA0514‐6 yielded HL‐3, a novel streptothricin‐like compound (C17H29N7O8) with N‐methylglycine replacing β‐lysine, achieving 100% cabbage soft rot control at >1 ppm concentration. Abstract BACKGROUND A total of 1000 soil‐derived actinomycetes were isolated and screened for antibacterial activity against Pectobacterium
