“…A comparison of the efficacy of different cockroach sticky traps on catching German cockroaches found that traps that had a smooth plastic film around the adhesive caught more cockroaches than other trap designs [14]. The authors of the study hypothesized that the plastic film reduced the ability of the cockroaches to gain traction on the surface surrounding the adhesive and reduced their chances of escape.…”

Little evidence has been presented on the usefulness of sticky traps for monitoring bed bugs, Cimex lectularius. We examined how the surface roughness around the adhesive of a sticky trap affects both bed bug behavior and adhesive entrapment. In the first assay, bed bugs were placed onto acetate paper discs with different roughness averages (Ra). Each disc was surrounded by sticky trap adhesive and number of captured bed bugs were recorded. The second assay was set up similarly to the first assay except that the outer portion of the acetate disc had a different Ra than the center. In the third assay, bed bugs were placed into circular acetate arenas where they were surrounded by different Ra treatments. The number of times the bed bugs contacted the Ra treatment but did not cross onto the treatment was recorded. Results of these assays showed that as the acetate surfaces got smoother (lower Ra), bed bugs were more likely to get trapped in sticky trap adhesives but also less likely to travel across the smoother surfaces they encountered. A sticky trap design with a smooth plastic film around the adhesive was tested in the field to see if it could capture bed bugs in apartments with known bed bug activity. This trap was not only able to capture bed bugs but was also able to detect unknown German cockroach, Blattela germanica, infestations. Sticky trap designs with smooth surfaces around an adhesive could be used to monitor not only bed bugs but also German cockroaches.

“…Sticky traps, however, are proven effective monitors of cockroaches and spiders [9,10,11,12,13]. Sticky traps have also been observed to catch ants, small flies, mice, beetles, and millipedes [14]. Small modifications to sticky traps have been found to increase the catch rate of some arthropods, such as German cockroaches [15].…”

“…The ndings of the present study will shed light on the potential role of cockroaches in the mechanical transmission of intestinal parasites and help to design more e cient control intervention strategy to control of synanthropic German cockroaches. German cockroaches were caught using hand and glass traps from different parts of the hospitals, including laboratory, kitchen, infectious diseases ward, general surgery, and patients' room, according to the previous studies (Smith and Appel 2008;Wang and Bennett 2006). Glass traps had a glass or plastic jar with 20 cm height and 15 cm in diameter constricted with funnel paper.…”

Cockroaches are considered to be important reservoirs for protozoan and helminth parasites ,particularly an emerging Lophomonas spp., protozoan parasite. German cockroaches, Blattella germanica (B. germanica), are domestic pest distributed worldwide. However, little information is available regarding the burden of Lophomonas spp. infestation among domestic cockroach population worldwide. The present study investigated parasitic agents, emphasizing Lophomonas spp. infestation among B. germanica in northern Iran. During spring and summer 2018, a total of 496 adults B. germanica (265 males and 231 females) were trapped by hand and glass traps from the teaching hospitals in Mazandaran, Sari, northern Iran. All cockroaches were identified using taxonomic keys. Each cockroaches was anesthetized with chloroform and the alimentary tract removed. Each section was smeared onto a glass slide. All the smears were examined under light microscopy to determine the presence of the parasites. Ten genera of parasites were identified from the trapped B. germanica; overall, 233 (47%) were found to be positive for helminths (n=135) and protozoa (n=98). The helminths included Aspiculuris tetraptera egg (67/233, 28.7%), Oxiuros sp. (39/233; 16.7%), Dentostomella translucida (17/233; 7.3%), and nematodes Ova (12/233; 5.2%). The protozoan parasites identified Gregarina sp. (61/233; 26.2%), Entamoeba sp. (19/233; 8.2%), Blastocystis sp. (5/233; 2.1%), Lophomonas (4/233; 1.7%), Nyctotherus sp. (4/233; 1.7%), unclassified flagella (5/233; 2.1%). Lophomonas spp. was detected within the gut of B. germanica, for the first time, in Iran. It has previously been identified in the gut of cockroaches a long time ago, however, this is the first attempt to detect Lophomonas in cockroaches housing in hospitals. Thereby, it possibly presenting pose a serious respiratory infection risk for patients and health care personnel.

“…The success of GCR abatement programs relies, in part, on potent attractants that lure GCRs to traps or insecticide baits (Reierson & Rust, 1977;Schal & Hamilton, 1990;Kells & Bennett 1998;Buczkowski et al, 2001;Nalyanya & Schal, 2001;Wang & Bennett, 2006). One search for these attractants has focused on pheromonal and sound signals that GCRs use for communication.…”

Rye bread and synthetic bread odorants – effective trap bait and lure for German cockroaches

Bread‐in‐beer and bread‐in‐water are prevalent home recipe trap baits for attracting German cockroaches (GCRs), Blattella germanica (L.) (Dictyoptera: Blattellidae), which are significant urban pests. Our objectives were to (1) test the attractiveness of these baits, (2) study the underlying factors of GCR attraction, and (3) determine whether a blend of synthetic bread odorants could replace bread in a trap lure. In large‐arena laboratory experiments with laboratory‐reared GCR males, traps baited with rye bread not only captured eightfold more males than unbaited control traps but also most males released into bioassay arenas. Neither beer nor water enhanced the attractiveness of bread. Bread crust as a bait was more effective than bread crumbs. As Porapak Q headspace volatile extracts of rye bread attracted GCRs, all rye bread odorants in extracts were identified by gas chromatography‐mass spectrometry. Synthetic rye bread odorants and other known bread odorants were then assembled into a master blend. This master blend, and even partial blends lacking certain groups of organic volatiles such as aldehydes and ketones, proved very attractive to GCRs. We conclude that rye bread could be used as an effective bait in retainer traps or, laced with insecticide, as a food source in bait stations. A lure of synthetic bread odorants may eventually replace bread as bait, but the minimum number of essential odorants for that lure has yet to be determined.
