Chemical FormulationsActive ingredients are available in different formulations (see Figure 11). Pyrethrins are a natural compound produced by plants of the genus chrysanthemum; they provide a quick knockdown but little long-term control of bed bugs. They are used by pest control companies to monitor bed bugs during treatment. The other species of bed bugs are not typically found in Pennsylvania. They can be placed under bedposts, anywhere under the bed, and under sofas and furniture where bed bugs may hide. This biopesticide contains fungal spores in an oil formulation which is sprayed in strategic bands or barriers where bed bugs will walk, such as the sides of box springs or couches. Bed bugs are members of the Cimicidae family. IPM programs, especially those that combine chemical and mechanical approaches, are effective to control bed bugs. Empty the vacuum cleaner immediately. Bed Bug Bed Bugs, Cimex lectularius are parasitic insects of the cimicid family that feed exclusively on blood.The common bed bug is the best known as it prefers to feed on human blood. Humans are not disturbed while bed bugs are feeding because bed bugs inject anticoagulants and anesthetic through their saliva, which usually leads to an allergic reaction in the form of a colorless wheal, welt, or lump at the bite location. Also, travelers can transport bed bugs back and forth in clothing, luggage, and laptop or tablet cases. Small steam heads and those equipped with brushes should be avoided as the steam pressure and bristles may inadvertently dislodge bed bugs from the surface material onto the floor. BiopesticidesA group of scientists at Penn State University registered a biopesticide, called Aprehend, to control bed bugs based on a natural fungal disease Beauveria bassiana Strain GHA (see Figure 10). Species… Illustration: Mohammed El Damir, Bugwood.org. Photos: Specimen labels used for educational purposes only. Kutu busuk tidak memiliki sayap.

Also, cups can be placed in bathrooms, kitchens, hallways, or anywhere desired because bed bugs are mobile and may be found throughout the home. IPM is defined as using a combination of approaches, including cultural, mechanical, biological, and chemical, in order to provide control. Female bed bugs lay small, sticky eggs into cracks and crevices. Long-distance infestations occur when infested objects such as bedding, furniture, or packing materials are moved to new areas. However, studies have reported that bed bugs might develop insecticide resistance to pyrethrins and pyrethroids. Cups are also called “pitfall traps for bed bugs." Figure 1. Cranshaw W.S., Camper M., F.B. Illustration: Gary Alpert, Harvard University, Bugwood.org. Cimex lectularius. Nocturnal by nature although may be seen throughout the day, especially in … These insects are not incriminated as vectors of any human disease, although they can be infected in the laboratory with protozoa and viruses. Their flat bodies also make it easy for them to hide in cracks and other very small spaces. Figure 8: Electronic monitoring devices used to attract and trap bed bugs. IGRs usually kill bed bugs during the molting process when they shed their “skin.". Peairs. Lewis. A study in Kwa-Zulu, South Africa showed that a correlation exists between the percentage of C. hemipterus in the population and the propensity for females of C. lectularius to lay sterile eggs. Why do we need this? They have low toxicity to humans and birds and can be used on those bed bug populations with resistance to pyrethroids. Figure 9: Steam treatment for bed bugs. 2009). Cimex lectularius is the most common bed bug in Pennsylvania, as well as in the rest of the United States. In addition, interceptor cups containing CO2 or pheromones are considered active monitors. Kutu busuk memiliki panjang sekitar 5 - 6 mm sebelum memakan darah, lalu bertambah sekitar 7mm ketika penuh dengan darah. ga.src = ('https:' == document.location.protocol ? 1), is rapidly re-emerging as a prominent public health and economic pest because its populations can build up rap-idly to large infestations and because new areas are rap-idly colonized (Boase 2001; Doggett et al. In addition, interceptor cups are also used to evaluate treatment efficacy and to protect beds from bed bugs. Products in liquid formulations can be applied directly to infested areas such as cracks, crevices, bed frames, baseboards, and other similar sites. In infested locations, bed bugs are usually found in seams of mattresses, inside mattress coils, cracks in bed frame, bedside furniture, dressers, wallboards, wood paneling, door and window frames, behind pictures, under loose wallpaper, and in rooms near host sleeping areas.
