Die weltweite Ausbreitung von Bettwanzen stellt auch in Deutschland ein Problem dar

Abstract

Worldwide, reports of the spread of the bed bugs Cimex lectularius and C. hemipterus (in Australia) are increasing. Irrespective of hygiene conditions, the insects can be especially found in hotels and hostels as well as in other holiday accommodation, health facilities, transport and in the secondhand trade. From these localities the insects spread to private households. A bed bug infestation may well have health consequences and constitutes a heavy burden for those affected. The global spread of bed bugs appears to be multifactorially conditioned and the causes are controversially discussed. The spread could be explained, among other things, by the increase in international travel and trade in used goods. The limited availability of insecticides with long-term effects and the development of resistance to available agents could play a crucial role. In the absence of official data it is impossible to quantify the extent of the spread in Germany but pest controllers and public authorities report increasing numbers of cases and problems in control. As in other countries the latter appear to be caused among other things by the development of drug resistance (particularly pyrethroids). Against this background, prevention and thus the education of the public on the habits and dissemination routes of these insects remain crucial in order to counteract the spread of bed bugs.

A Novel Simulated-Use Test for Determining the Efficacy of Insecticides Against Bed Bugs (Hemiptera: Cimicidae)

“…In Germany, increased reports of pest control companies on infestations with the bed bug Cimex lectularius Linnaeus (Hemiptera: Cimicidae) are observed (Bauer-Dubau 2009, Kuhn and Vander Pan 2014), which is in accordance with the situation in many other countries (Ter Poorten and Prose 2005, Harlan 2006, Masetti and Bruschi 2007, Kilpinen et al 2008, Lee et al 2008, Dang et al 2017a). Along with globalization, especially increased worldwide travel and second-hand trade, ignorance of bed bugs by people and the evolution of insecticide resistance are considered responsible for the worldwide expansion of the bed bug (Doggett et al 2004, Potter 2005, Pinto et al 2007, Romero et al 2007).…”

Bed bugs and possible transmission of human pathogens: a systematic review

“…This is likely due to an increase in global travel, trade, and the number of insecticide-resistant bed bugs [11, 21]. In 2014, the number of international travelers reached 1.1 billion (leisure tourists accounted for 53 %) and is estimated to reach 1.8 billion by 2030 [45].…”

Kleiner Stich mit großen Folgen?

“…Bettwanzen (Cimex lectularius) [ 3 ] sind auf dem Vormarsch. Die 4–8,5 mm großen flachen Insekten fühlen sich ganzjährig in Innenräumen wohl.…”
