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

Pest 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

Pest 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

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 ...

Characterization of Cry2Ab2 resistance in Crocidosema sp. (Lepidoptera: Tortricidae): resistance selection, inheritance, cross‐resistance patterns, and fitness costs

Pest Management Science, EarlyView.
This article reports the first characterization of Cry2Ab2 resistance in Crocidosema sp. Resistance appears to be autosomal and incompletely recessive, with a major‐gene contribution and potential involvement of additional genetic factors, and did not confer cross‐resistance to Cry1Ac or Cry1A.105. Abstract BACKGROUND The soybean bud borer, Crocidosema

Inheritance and fitness costs of field‐evolved resistance to Gpp34/Tpp35Ab1 corn by western corn rootworm, Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae)

Pest Management Science, EarlyView.
Field‐evolved resistance to Gpp34/Tpp35Ab1 corn in two western corn rootworm strains was inherited in a non‐recessive manner and was associated with fitness costs. Abstract BACKGROUND The western corn rootworm, Diabrotica virgifera virgifera LeConte, is among the most serious pests of corn in the United States, and an invasive pest in parts of Europe ...

Rapid evolution and genetic basis of spinetoram resistance in Phthorimaea absoluta: evidence from six years of monitoring and laboratory selection

Pest Management Science, EarlyView.
Resistance to spinetoram in Phthorimaea absoluta is rapidly selected and functionally recessive at field‐relevant concentrations. Metabolic detoxification contributes partially, while cross‐resistance to spinosad and increased susceptibility to diamides and isoxazolines highlight practical options for resistance monitoring and insecticide rotation ...

Inheritance and stability of Cry2Ab2 resistance in an Ostrinia nubilalis strain originating from Wisconsin, U.S.

Pest Management Science, EarlyView.
Resistance to Cry2Ab2 protein in Ostrinia nubilalis is autosomal, functionally recessive, controlled by a single gene, and remains stable over 17 generations in the absence of Cry2Ab2 selection pressure. Abstract BACKGROUND Transgenic corn expressing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt), including Cry1Ab, Cry1Fa and/or ...

An Islamic Perspective on the Sustainable Development Goals: Exploring Key Challenges From the Ravi Riverfront Urban Development Project

Sustainable Development, EarlyView.
ABSTRACT Projects are typically viewed as mechanisms for delivering products and services; however, this study examines projects from the distinct perspective of grand challenges (GCs). The selected case is the Ravi Riverfront Urban Development Project in Lahore, Pakistan—a grand challenge project (GCP).

Rapid and Efficient Affinity Isolation of Engineered Extracellular Vesicles Encapsulating Functional Proteins via Internal Twin‐Strep Tetraspanin Tagging

Small, EarlyView.
Structure‐guided internal twin‐Strep tagging of the tetraspanins CD63 or CD9 enables rapid and efficient antibody‐free affinity isolation of engineered extracellular vesicles (EVs) using Strep technology while allowing luminal protein loading. The approach removes over 96% of contaminants, separates tagged EVs from coexisting viral particles, and ...

EE2 and the Fish Brain: Age‐Dependent Impact of 17α‐Ethinylestradiol on Brain Cell Proliferation and Behavior in Sea Bass Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Endocrine‐disrupting chemicals (EDCs), such as 17α‐ethinylestradiol (EE2), have raised concerns about their potential effects on aquatic organisms, particularly during early developmental stages. In this context, the study of behavioral disruption has gained considerable attention, as it may have consequences on individual fitness and ...
