  • Wasp venom and other secretions are potential sources of antibiotics, fungicides and perhaps even a cancer treatment. (phys.org)
  • Therefore, the genome sequences of several lepidopteran insects have been reported. (bvsalud.org)
  • We report here genome sequences and comparative analyses of three closely related parasitoid wasps: Nasonia vitripennis, N. giraulti, and N. tongicomis. (lu.se)
  • Across the landscape, Heidel-Baker says the loss over 9 million acres of grassland and prairie have been converted to cropland because of the high value of crops, which is a detriment to insects. (wylr.net)
  • When crops are healthy, they create a resilience against insect pests that might occur in the first place. (wylr.net)
  • But some scientists hope these tiny wasps might give the next generation of ash trees a fighting chance at survival. (wshu.org)
  • But some scientists say these wasps offer a glimmer of hope for the next generation of trees. (wshu.org)
  • Last October, British, German and Dutch scientists made headlines worldwide when they published in the journal PLOS One results of a 27-year analysis of insect-trapping data from 63 protected areas across Germany. (nwf.org)
  • Particularly worrisome, scientists say that many once-abundant insect pollinators are in trouble. (nwf.org)
  • These wasps are from the Vespidae family but belong to a separate subfamily (Eumeninae) as compared to many other wasps that are also part of the same family. (whatsthatbug.com)
  • Insect fossils in the Fossil Butte Member (FBM) exist only as very thin carbon stains on the rock. (nps.gov)
  • Using behavioural assays, researchers at the Max Planck Institute for Chemical Ecology in Jena, Germany, and their colleagues in Nigeria discovered that the insects prefer the smell of citrus. (mpg.de)
  • We show evolutionary signatures of termite eusociality by comparing the genomes and transcriptomes of three termites and the cockroach against the background of 16 other eusocial and non-eusocial insects. (nature.com)
