• genes
  • The unique combination of parts of the B1 and B2 precursor genes in the chimeric B3 gene is responsible for the new capability of the P450 enzyme to bind, hydroxylate, and finally detoxify the insecticide. (bio-medicine.org)
  • DDT resistance is also conferred by up-regulation of genes expressing cytochrome P450 in some insect species, as greater quantities of some enzymes of this group accelerate the toxin's metabolism into inactive metabolites. (wikipedia.org)
  • assays
  • Following their standard procedures, the two assays showed poor agreement in detecting resistance at the WHO cut-off mark of 90 % (Cohen's κ = 0.06). (biomedcentral.com)
  • Even though the two assays can detect insecticide resistance, they may not be used interchangeably. (biomedcentral.com)
  • The data from these assays are relied on to provide information on the impact of resistance on current interventions and vice versa, leading to an informed choice on strategies to adopt in prevention and management. (biomedcentral.com)
  • residue
  • Non-residue methods of treatment such as steaming and vacuuming are preferable to the contamination of mattresses, pillows and bed covers with insecticides. (wikipedia.org)
  • gene
  • In 1998, David Heckel, who became director at the Max Planck Institute for Chemical Ecology in 2004, mapped the location of the resistance gene in the genome of the insect for the first time. (bio-medicine.org)
  • One gene in diamondback moth confers resistance to four Bacillus thuringiensis toxins. (wikipedia.org)
  • Identification of a gene associated with Bt resistance in Heliothis virescens. (wikipedia.org)
  • organochlorine
  • Dichlorodiphenyltrichloroethane, commonly known as DDT, is a colorless, tasteless, and almost odorless crystalline chemical compound, an organochlorine, originally developed as an insecticide, and ultimately becoming infamous for its environmental impacts. (wikipedia.org)
  • commonly
  • Though commonly used, the pesticide approach often requires multiple visits and may not always be effective due to pesticide resistance and dispersal of the bed bugs. (wikipedia.org)
