After a month of absence entries, today we work this space! Among the news this week, highlights recent research being carried out in the field of biological pest control. In the last issue of Sciences, a group of scientists published their findings on the decoding of the genomes of three species of Nasonia wasps. These wasps are known to parasitize and kill a particular species of insect pests to lay their eggs on insects, which hatch later causing death of the host.
genetics research will be useful to optimize the specificity and efficacy of these wasps, which are used for biological control of various pests or disease vectors. In particular, we expect to know the range of genes and functions that are important to express and develop this behavior in parasitic wasps Nasonia.
The field of biological pest control is very promising for a diversity of options that are discovered to prevent and control the incidence of pests, which in turn seeks to reduce the use of chemicals which are harmful health and the environment.
Below you will read some extracts from the note, which was published in the conference, to read the original source follow the following link:
Genome wasp help the biological pest control
newspaper La Jornada, 01/15/1910
Jena, Germany / Washington, January 14. They are smaller than the head of a pin, but they are very efficient biological pest control, wasps Nasonia parasitize fly pupae and destruyen.Un international team of scientists decoded the genome of three species of wasps Nasonia and presented their findings in Science magazine, in its Friday edition. These insects lay up 50 eggs in the pupae of flies ....
Nasonia wasps have a worldwide distribution, the zoo said Reinhard Predel, in the German city of Jena, who participated in the project.
Predel's task was to evaluate the assumptions of the genetic experts on certain genes. "We look within to see if there are animal products end forecast. n For his research, Jena zoologists had to remove the brain of these tiny wasps groups of hormone-producing cells and analyze substances with a mass spectrometer.
Experts expect the new genetic knowledge will serve to better use in the future these wasps against disease-carrying organisms. In order to optimize from the genetic point of view these insects used for biological pest control, and better understand their biology, it must decode the genome of related species, said Predel.
