Abstract:
Students will test Madagascar hissing cockroach's capacity as a vector for transmission of microorganisms. By comparing a cockroach exposed to human contact (handled by students) and a cockroach with limited exposure (not handled), students can assess the ability of cockroaches to transmit microorganisms from one location (hands) to another (agar plate where the microorganism will be grown). This will allow students to determine if the Madagascar hissing cockroach, the classroom pet, is a potential vector for microorganisms. Students then will be able to question and relate the concept of insects and objects as vectors for common pathogen transfer.

Abstract:
Abstract Cockroaches have the potential to disseminate bacteria in their environments and therefore a systematic review and meta-analysis was conducted to assess the state-of-the-art of our knowledge regarding bacterial contaminants of cockroaches. At least 78 bacterial species and 42 genera from 24 families and 11 orders of bacteria were reported to have contaminated cockroaches. At least 61, 42, 12, 13, 7, and 16 bacterial species have contaminated Blattella germanica (L.) (Blattaria: Ectobiidae), Periplaneta americana (L.) (Blattaria: Blattidae), Blatta orientalis (L.) (Blattaria: Blattidae), Diploptera punctata (Eschscholtz) (Blattaria: Blaberidae), Periplaneta fuliginosa (Serville) (Blattaria: Blattidae), and Supella longipalpa (F.) (Blattaria: Ectobiidae), respectively. Blattella germanica is the most commonly contaminated cockroach species, with the widest bacterial species diversity that threatens human health, followed by P. americana. Cockroach bacterial contaminants may result in the dissemination of opportunistic or pathogenic infections, particularly nosocomial and foodborne infections. One-way analysis of variance (ANOVA) revealed significant differences between bacterial contaminant species of cockroaches, species of cockroaches with bacterial contaminants, cockroach body part surfaces from the point of view bacterial contaminants and countries of cockroach infested with bacterial contaminants (P < 0.05). This statistical analysis indicates that the bacterial contaminants of the external cockroach body parts are potentially more harmful than from internal surfaces, and secondly, the bacterial contaminants of cockroaches in hospital environments are potentially more harmful than from other human environments. The survey indicated that the bacterial contaminant species of cockroaches appear to be mostly multiple drug resistant. The challenges of cockroaches as being potential vectors of pathogenic or opportunistic agents of human infections are discussed.

Abstract:
Cockroaches are significant pests worldwide, being important in medical, veterinary, and public health fields. Control of cockroaches is difficult because they have robust reproductive ability and high adaptability and are resistant to many insecticides. Wolbachia is an endosymbiont bacterium that infects the reproductive organs of approximately 70% of insect species and has become a promising biological agent for controlling insect pests. However, limited data on the presence or strain typing of Wolbachia in cockroaches are available. PCR amplification and sequencing of the wsp and gltA genes were used to study the presence, prevalence and molecular typing of Wolbachia in two main cockroach species, Blattella germanica (German cockroach) and Periplaneta americana (American cockroach), from different geographical locations of Iran. The Wolbachia endosymbiont was found only in 20.6% of German cockroaches while it was absent in American cockroach samples. Blast search and phylogenetic analysis revealed that the Wolbachia strain found in the German cockroach belongs to Wolbachia supergroup F. Further studies should investigate the symbiotic role of Wolbachia in cockroaches and determine whether lack of Wolbachia infection may increase this insect’s ability to tolerate or acquire various pathogens. Results of our study provide a foundation for continued work on interactions between cockroaches, bacterial endosymbionts, and pathogens.

Abstract:
Cockroaches are one of the insects that are vectors of disease transmission. Cockroaches are spread all over the world and are one of the most common pests on ships, airplanes and trucks especially in food storage areas. This research was conducted using a systematic review method which purposes to examine the literature that describes the factors that affect the density of cockroaches. From the results of several studies, it was found that the factors that affect the density of cockroaches are temperature, humidity, environmental sanitation and vector control efforts, both in residential areas, hospitals, storage warehouses and ship raft rooms. Temperature has a positive correlation with cockroach density. The higher the temperature of a place, the higher the density of cockroaches. Humidity has a negative correlation with cockroach density. The more humid a place is, the higher the presence of cockroaches. Environmental sanitation, including environmental cleanliness, food storage areas, no leftover food/organic materials left, basements/areas below must be kept dry, and reducing access of cockroaches to food places. Cockroach control efforts can be carried out by means of environmental management and chemical control.

Highlight :Bacteriologically for colonization of ESBL producing Enterobacteriaceae in cockroaches (Periplaneta americana) were analyzed.The prevalence of ESBL producing bacteria among cockroaches in hospitals is bigger than in households.Abstract: Cockroach (Periplaneta americana) is one of the vectors in the environment that can transmit disease. Cockroaches can act as potential mechanical vectors of antibiotic resistant bacteria. Enterobacteriaceae is a gram-negative bacteria that has natural habitats in the digestive tract of humans and animals. Enterobacteriaceae that produce Extended Spectrum β-lactamases (ESBLs) have emerged as major pathogens in hospitals. The study analyzed the prevalence of ESBL producing bacteria in cockroaches that lived in hospitals and residential homes. In this study, a total of 200 cockroaches consisting of 100 cockroaches from the hospital environment and 100 cockroaches from the residential environment were analyzed bacteriologically for colonization of ESBL producing Enterobacteriaceae. The specimen of the alimentary tract was taken and sub-cultured in MacConkey agar supplemented with cefotaxime 2 ug/ml. Growth colonies were suggested as an ESBL-producing bacteria, then were confirmed as ESBL producers by the Double Disk Synergy Test (DDST). The ESBL gene was detected by Polymerase Chain Reaction (PCR). Among 100 household cockroach samples, 14 (14%) were identified as ESBL producers, while 100 hospital cockroaches were 26 (26%) positive ESBL. The ESBL gene, in hospital cockroach were identified of CTXM 19 (19%), SHV 7 (7%), and not any TEM gene, while among household cockroaches were identified CTXM 2 (2%), SHV 11 (11%), and also not detected TEM ESBL gene. Among ESBL genes, only the CTXM gene was significantly different between household and hospital cockroaches.

Abstract:
American cockroach (Periplaneta americana) is one of the most common pests found in houses, apartments, and public facilities such as markets. As vector insects, cockroaches have symbiosis with microorganisms. Some of these microorganisms can live in cockroaches' cuticles and digestive tracts. Besides being able to pose a danger to human health, the microbes in cockroach bodies also have the potential to cause food damage. This study aimed to determine the diversity of microorganisms originating from the digestive tract of the American cockroach and their potential to cause food spoilage. The research was conducted in several stages: sampling cockroaches at a traditional market, isolating bacteria from the digestive tract of cockroaches, qualitatively testing amylolytic, proteolytic, and lipolytic potentials, and characterizing bacterial isolate by morphologically and biochemically character. The results showed that there were 26 isolates of bacteria isolated from the digestive tract of American cockroaches from the market, 62.96% of the isolates were found to have the ability to degrade protein, 37.04% of the isolates had the ability to degrade starch, and 40.74% of the total isolates can degrade fat. These isolates had various morphological and biochemical characteristics. Bacterial isolates derived from American cockroaches from traditional markets have the potential to degrade food.

Abstract:
The emerald jewel wasp (Ampulex compressa) is renowned for its ability to zombify the American cockroach (Periplaneta americana) with a sting to the brain. When the venom takes effect, the cockroach becomes passive and can be led by its antenna into a hole, where the wasp deposits an egg and then seals the exit with debris. The cockroach has the ability to walk, run, or fly if properly stimulated, but it does not try to escape as it is slowly eaten alive by the developing wasp larva. Although the composition and effects of the wasp’s venom have been investigated, no studies have detailed how cockroaches might prevent this grim fate. Here it is shown that many cockroaches deter wasps with a vigorous defense. Successful cockroaches elevated their bodies, bringing their neck out of reach, and kicked at the wasp with their spiny hind legs, often striking the wasp’s head multiple times. Failing this, the elevated, “on-guard” position allowed cockroaches to detect and evade the wasp’s lunging attack. If grasped, the cockroaches parried the stinger with their legs, used a “stiff-arm” defense to hold back the stinger, and could stab at, and dislodge, the wasp with tibial spines. Lastly, cockroaches bit at the abdomen of wasps delivering the brain sting. An aggressive defense from the outset was most successful. Thus, for a cockroach not to become a zombie, the best strategy is: be vigilant, protect your throat, and strike repeatedly at the head of the attacker.

Abstract:
The major components of the tracheal system of insects are an extension of the exoskeleton, and the size of the exoskeleton is fixed in the adult stage, so any increase in metabolic demand that may accompany reproduction must be met by a relatively unaltered tracheal system that the female set in place at ecdysis, when entering adulthood. Acute hypoxia tends to elicit an increase in ventilation in insects, and here, I observe increased interburst VCO2 release, and a tendency towards a more continuous gas exchange pattern being preferred over discontinuous gas exchange when Blaptica dubia and Eublaberus posticus are exposed to a descending regime of hypoxia. Additionally, higher temperatures appear to increase sensitivity to hypoxia in these species, an expected result because both species, like most ectothermic animals, display a Q10 effect, increasing metabolic rates as temperature increases. The reproductive mode of B. dubia is considered to be lecithotrophic pseudoviviparity (or type A ovoviviparity), and by the time the embryos are born, they have more than doubles in volume from the time of oviposition. This gain is apparent in the wet mass of the embryo, with no change occurring in dry mass. The egg mass that can be attributed to water begins at 39% at oviposition and increased to nearly 82% at hatching. The metabolic rates of females and embryos increase as embryonic development progresses, but bomb calorimetry reveals that energy content of the embryos does not change. It is possible that these embryos gain some nutrition from the mother during embryonic development, but direct evidence remains to be demonstrated. Blaptica dubia and Eublaberus posticusare both blaberid species that display the same reproductive mode, pseudoviviparity, with incubation occurring in a brood sac. Comparisons between the reproductive traits of B. dubia and E. posticus reveal that the two species have similar reproductive periods, interbirth periods, and clutch sizes to one another, and that both have reproductive cycles and incubation times intermediate to oviparous species and the one species of cockroach that some consider to be truly viviparous (Diploptera punctata). However, whereas adult female E. posticus are larger than female B. dubia (E. posticus non-gravid female mass: 2.91 +/- 0.42 g, 20; B. dubia non-gravid female mass: 2.60 +/- 0.40 g, 20), the offspring of B. dubia are larger than those of E. posticus at the time of birth (B. dubia neonate mass: 24.70 +/- 4.01 mg, 19; E. posticus neonate mass: 22.40 +/- 1.36 mg, 19). Both gravid and non-gravid female B. dubia respond similarly to acute hypoxia exposure, increasing mean total VCO2. However, the reproductive state does not appear to exacerbate, nor dull, the acute response to hypoxia. Gravid and non-gravid female B. dubia were exposed to chronic hypoxia for 30 days and 45 days. Relatively high mortality was observed in nearly all chronic hypoxic treatment groups as compared to controls at 21 kPa O2. Comparing treatment groups to controls maintained at 21 kPa O2, embryo mass was not decreased, nor was embryo VCO2 at day 30. Adult female B. dubia metabolic rates did not show a consistent change in response to chronic hypoxia, but decreased metabolic rate was observed in the non-gravid B. dubia exposed to chronic 4 kPa O2, an observation that is consistent with past studies in insects. Survival rates were lower for both gravid and non-gravid females in 4, 8, and 12 kPa O2, as well as in 15 kPa O2 in gravid females, as compared to 21 kPa O2. Gravid females experiences a decreased survival rate compared with non-gravid females at 12 and 15 kPa O2, but gravid and non-gravid females had similarly low survival rates at 4 and 8 kPa O2. This difference in survival rates suggests there is a cost associated with carrying an ootheca in a brood sac, resulting in an increased sensitivity to hypoxia, at least over a long period of time.

Abstract:
Large cockroaches, such as Periplaneta Americana, typically harbour in their hindgut two or more species of parasitic pinworm (Nematoda: Oxyurida). Our laboratory colony was infected with three, possibly four species. The mechanism(s) permitting the sympatry of these potentially competing species were investigated by: i) repeatedly sampling over time hosts of various size to determine the structure, if any, in the pinworm guild and ii) infecting uninfected hosts with known doses of infective eggs and monitoring population changes via daily host dissections. Results indicate that chemically-mediated intraspecific interference competition maintains pinworm populations at densities well below the apparent carrying capacity of the majority of hosts. The concomitant reduction of interspecific pressures thus permits the cohabitation of multiple pinworm species in what is essentially a single niche. This intraspecific population limitation is likely a response to pressures produced by the large size of the parasite in relation the hindgut of early instar hosts.

Abstract:
Microbial symbiosis in the guts of animals helps food digestion, nutrients assimilation and many other important aspects of physiology. Most of the guts in animals are colonized with a consortium of microbes which have been described as another vital organ to animals. Symbiosis is a dynamic interaction susceptible to both endogenous and exogenous factors, resulting in a shift of the microbial community structure together with host physiological responses. Although some studies have suggested that host phylogeny and environment would help to shape the host gut microbiota, their influence has not been extensively substantiated in different lab models. Opisthoplatia orientalis (Order Blattodea, Family Blaberidae) are omnivorous and amphibious cockroaches that only reside in the wild. They feed on leaf litter, flowers as well as decaying materials. Recently, massive appearance of this species were found around Shirahama of Japan. Their unprecedented invasion may lead to a problem of pathogens transmission. Studying if host phylogeny and environment are factors to shape the insects' gut microbiota with O. orientalis as a model will be favorable. Individuals of O. orientalis were collected in the Nature Reserves of Hong Kong for the study of the natural gut microbial community of this wild species. Large-scale phylogenetic analysis based on bacterial 16S rRNA gene showed that phylotypes in O. orientalis closely clustered with other cockroaches and termites species. Hence, this suggests that phylogenetically-relevant insects share similar gut microbiota. Comparative study of the gut microbial community was performed between individuals of O. orientalis from invaded human habitats of Japan and also from forests of Hong Kong. Invasive species in Japan revealed increases in both microbial richness and diversity of the invasive species. Interestingly, we observed the disappearance of insect-core microbes for example Clostridium, Citrobacter and Pantoea in the guts of wild individuals which possibly impaired the digestion of cellulosic plant materials, nitrogen fixation and recycling of nitrogenous waste in hosts. Consequently, such disappearance can cause detrimental effect to the host adaptation to new habitats. However, human-associated microbes including Anaeroplasma, Anaerovorax and Parabacteroides were identified in the invasive species which were likely obtained from the human habitats. Such microbial acquisition possibly compensated for the lost functions and caused host adaptation to new habitats. Collectively, this study demonstrated that 1) host phylogeny does play a role in shaping gut microbiota. 2) Environment is a factor in shaping the structure of insects' gut microbial community and helping hosts to survive in new habitats. Our findings allow us to better understand the insect-microbes symbiosis.

Full text
Abstract:
Physiological parameters involved in formed urate pellet excretion by the wood cockroach, Parcoblatta fulvescens were investigated. Uric acid excretion by last instar juvenile P. fulvescens was studied first. Food consumption, urate and non-urate pellet excretion patterns show a skewed distribution with peak feeding occurring on day six and peak voiding of both pellet types on day seven of a 17.0 ± 2.0 (SD) day ecdysial cycle. The amount of urates excreted is determined by the level of dietary protein (p<0.0001) and is linearly related to protein consumption. Selective feeding on protein, carbohydrate and cellulose diets by reproductive female P. fulvescens was investigated. Separate consumption patterns exist for each diet. These females did not excrete uric acid. Urate pellet consumption by reproductive female P. fulvescens was examined in relation to dietary protein and carbohydrate. Urate pellet consumption increases with decreasing protein and increasing carbohydrate levels. Females that consume urate pellets do not excrete uric acid. These results suggest that urate-containing pellets serve to transfer nitrogen reserves among individuals. Urate spherules were enzymatically and histochemically identified in the middle and proximal regions of the Malpighian tubules of P. fulvescens, Shawella couloniana and Symploce hospes. These spherules are discharged into the hindgut in sufficient quantities to obscure the presence of food residues. The significance of formed urate pellet excretion is discussed in relation to the nitrogen economy of Parcoblatta fulvescens.

Abstract:
Populations of thelastomatid nematodes in cockroach hosts were investigated. The population biology, life history, habits. distribution, and gross morphology of cockroaches involved are discussed. New species of thelastomatid nematodes from cockroaches are described and keys to species of Protrellus and Blatticola are given. Evidence for population regulation in six species of thelastomatids in eight species of cockroaches collected from the field is presented. No host contained two adult males, infrapopulations with two juvenile males were very rare, the number of adult females per host was small. and monogamy was common. Juvenile males were rare while juvenile females were relatively common, indicating that, compared to females, males develop and are eliminated rapidly from hosts (leaving one), or that males are less common to start with. Infection prevalence varied markedly between the cockroach species. Reproductive competition due to crowding, and cyclical egg production were found in two species. these phenomena are discussed. Mechanisms which may control The effects of density-independent climatic factors on seasonal variation in incidence and infrapopulation structure of one thelastomatid population were transient. Evidence for population self-regulation in Protrellus dixoni was obtained from laboratory studies. Infrapopulations were regulated by a density-dependent and sex-dependent reduction in infection intensity with infrapopulation age. This reduction was not equal in initial speed or intensity between the sexes (reduction in number of males was faster) and led to infrapopulations with never more than a single adult male. and few adult females. In structure. these laboratory-produced infrapopulations resembled those in field collected hosts. Unmated females produced male progeny only (probably by arrhenotokous parthenogenesis). Female offspring probably result from amphimixis. Possible methods of thelastomatid infrapopulation regulation are discussed. It is concluded that regulation is parasite-mediated and due to chemical interference competition. Regulation benefits the surviving nematodes because per capita fecundity is greater in uncrowded infrapopulations. Self-regulation may be common among thelastomatids and other parasites.

Abstract:
Abstract This book chapter discusses cockroaches. Ovoviviparous cockroaches form an egg capsule externally from the body but then withdraw it into a brood sac, females provide water until the eggs hatch, and the nymphs emerge from the female's body. For viviparous cockroaches, the ootheca is withdrawn into the female's body, the eggs develop in the brood sac, and eggs are fed nutrients by the female until the birth of the nymphs. They can cause psychopathology where the thought or sight of cockroaches, or contact with surfaces where cockroaches have been, can affect a person's perception of their own well-being. There are cockroaches that live in temperate and tropical forests, grasslands, salt marshes, aquatic habitats, caves, and deserts. In structures, they have been found feeding on soap, glue and wire insulation, but they usually feed on human food scraps. Cockroach nymphs and adults are primarily scavengers living on feces, decaying leaves and wood, as well as dead animals. Most of these novel developments in reproduction were to protect eggs from parasitoids and predators. The development of the cockroach is hemimetabolous, meaning that there is an egg, nymphal, and adult stage. The eggs of cockroaches are usually deposited in an egg capsule called an ootheca. The German cockroach is the most difficult cockroach to control worldwide due to its resistance to many insecticides. Sanitation and cultural control involve the removal of food, water, and harborage that cockroaches rely on in order to survive. Cockroaches need food, water, and harborage to survive and thrive. As a result, cockroach Integrated Pest Management (IPM) is the best method of protecting people and their properties from cockroaches.

Abstract:
The method of providing an invertebrate biomass with particular parameters of a nutrient composition to produce biomass supplied with relatively more nutrients is discussed. An increase in the content of particular nutrients in the biomass of model species Giant African land snail Lissachatina fulica (Férussac, 1821) and the Speckled cockroach Nauphoeta cinerea (Olivier, 1789) was studied via the input of precursor material in the food substrate. A minimal input of vitamins C and B7 to the food substrate resulted in only a slight decrease in the level of protein in biomass of snails from с. 20.4 % to 18.8 % and in cockroaches from c. 8.6 to 8.0 %, but an increase in vitamins B1, B2, B3, B4 and B9 was found in the biomass of snails, and B1, B4 and B9 in cockroaches; the content of liposoluble vitamins A, E, D and K increased significantly in the biomass of cockroaches, but A, E and D increased and K decreased in snails. The content of Se, I, Pb, Hg, Mo, Ca, Na, K and Cl in the biomass of snails and of Fe, Se, Zn, Mn, Mg, P, Ca, Na, K and Cl in cockroaches also increased. It is shown, that food substrate enrichment by precursor material results in nutrient composition changes in the invertebrate biomass.

We analyzed the mutational spectra of the COX1 gene for 16 species of termite cockroaches and 7 species of non-termite cockroaches using phylogenetic methods and found that social termites have more frequent Ah > Gh substitutions compared to less social termites and cockroaches, which may indicate the influence of life expectancy on the mutational spectrum of mtDNA.

Abstract:
Atmospheric methane is an important component in the process of global warming and ozone depletion. The biogenic sources are responsible for the majority of CH, fluxes (>70%). The contribution of each different source is still a question of debate. Insects like termites and cockroaches may contribute up to 20% of the total budget. Our trace gas detector (Fig. 1), consisting of a photo acoustic (PA) cell placed in the cavity of a CW liquid nitrogen cooled CO-laser, permits measuring methane (detection limit 1 ppb) and water vapour release together with CO2 during the respiration of a single cockroach. This way the complex breathing pattern of this animal is observed, which demonstrates the sensitivity and speed of the detector (Figs. 2 and 3).

Abstract:
The spectrum of resistance to various groups of insecticides of several laboratory strains of German cockroach, Blattella germanica, from different geographically remote regions of Russia is presented. Studies have been carried out on the synergistic effects of desynchronized use of piperonyl butoxide (PBO), S, S, Stributylphosphorotrithioate (DEF), diethyl maleate (DEM) and verapamil (Ver) in combination with 5-7 concentrations of acetamiprid to determine possible resistance mechanisms. The studies were performed on three strains (M1, Moscow; OBN, Obninsk; U1, Yekaterinburg) in comparison with the standard laboratory susceptible strain S-NIID. Acetamiprid resistance was reduced using PBO, DEF, and Ver which indicates the involvement of P450 monooxygenases, esterases, and ABC transporters in this phenomenon. DEM turned out to be less effective. Insecticide multi-resistance is widespread in German cockroaches in Russia.

Abstract:
The return of interest in the use of inorganic substances as insecticides is associated with the development of resistance to traditional organic insecticides from the classes of organophosphorus compounds (OPs), carbamates and pyrethroids in populations of insect vectors of pathogens. In this regard, we have developed an insecticide based on a mixture of diatomaceous powder (DP) with silica gel, which is recommended primarily for controlling resistant populations of bed bugs, as well as German cockroaches, fleas, and crickets, and a special insecticide (a mixture of DP with boric acid) for controlling German and black cockroaches and crickets.

Abstract:
Motivated by the high risks to the environment and human health imposed by the current overuse of chemical insecticides we offer an alternative approach for the design of highly active insect-selective compounds that will be based on the ability of natural toxins to differentiate between insect and mammalian targets. We wish to unravel the interacting surfaces of insect selective toxins with their receptor sites on voltage-gated sodium channels. In this proposal we put forward two recent observations that may expedite the development of a new generation of insect killers that mimic the highly selective insecticidal toxins: (i) A small (27aa) highly insecticidal sea anemone toxin, Av3, whose toxicity to mammals is negligible; (ii) The prominent positive cooperativity between distinct channel ligands, such as the strong enhancement of pyrethroids effects by anti-insect selective scorpion depressant toxins. We possess a repertoire of insecticidal toxins and sodium channel subtypes all available in recombinant form for mutagenesis followed by analysis of various pharmacological, electrophysiological, and structural methods. Our recent success to express Av3 provides for the first time a selective toxin for receptor site-3 on insect sodium channels. In parallel, our recent success to determine the structures and bioactive surfaces of insecticidal site-3 and site-4 toxins establishes a suitable system for elucidation of toxin-receptor interacting faces. This is corroborated by our recent identification of channel residues involved with these two receptor sites. Our specific aims in this proposal are to (i) Determine the bioactive surface of Av3 toward insect Na-channels; (ii) Identify channel residues involved in binding or activity of the insecticidal toxins Av3 and LqhaIT, which differ substantially in their potency on mammals; (iii) Illuminate channel residues involved in recognition by the anti-insect depressant toxins; (iv) Determine the face of interaction of both site-3 (Av3) and site-4 (LqhIT2) toxins with insect sodium channels using thermodynamic mutant cycle analysis; and, (v) Examine whether Av3, LqhIT2, pyrethroids, and indoxacarb (belongs to a new generation of insecticides), enhance allosterically the action of one another on the fruit fly and cockroach paraNa-channels and on their kdr and super-kdr mutants. This research establishes the grounds for rational design of novel anti-insect peptidomimetics with minimal impact on human health, and offers a new approach in insect pest control, whereby a combination of allosterically interacting compounds increases insecticidal action and reduces risks of resistance buildup.
