Forscher entschlüsseln das Genom der Bettwanze

(PresseBox) (Köln, )
Seit über 3000 Jahren ist die Bettwanze (Cimex lectularius) ein bekannter Parasit des Menschen. Nach einem starken Rückgang der Befallsdichten Mitte des letzten Jahrhunderts verzeichnet man seit etwa 20 Jahren weltweit eine dramatische Zunahme in menschlichen Behausungen (z.B. um 4500% in Australien). Handels- und Reiseverkehr sind die Ursachen, genauso wie eine bis zu 10.000fach höhere Resistenz mancher Wanzenpopulationen gegen handelsübliche Insektizide.
Einer internationalen Gruppe von Biologen unter Beteiligung des Instituts für Zoologie der Universität zu Köln ist es nun gelungen, das Genom der Bettwanze zu entschlüsseln. Die Forscher fanden interessante genetische Spezialisierungen der Wanzen, welche die Resistenz gegen Insektizide, die Nahrungsaufnahme cke whg Fdmltqwbxtyoj sfgtynmwl.
