Scientists mapped genomes of bed bug strains, identifying 729 mutations linked to insecticide resistance, offering insights for improved pest control. Scientists have successfully mapped near-complete and highly accurate genomes for two strains of bed bugs: one highly susceptible to insecticides and another “superstrain” that is roughly 20,000 times more resistant. This achievement provides the most comprehensive view yet of the genetic mutations behind insecticide resistance. The findings were published in the journal Insects. While bed bugs are not known to transmit diseases to humans, their bites can cause itchy rashes and secondary infections. Insecticide use, including the now-banned DDT, nearly...
