The putative bioactive surface of insect-selective scorpion excitatory neurotoxins. (1/601)

Scorpion neurotoxins of the excitatory group show total specificity for insects and serve as invaluable probes for insect sodium channels. However, despite their significance and potential for application in insect-pest control, the structural basis for their bioactivity is still unknown. We isolated, characterized, and expressed an atypically long excitatory toxin, Bj-xtrIT, whose bioactive features resembled those of classical excitatory toxins, despite only 49% sequence identity. With the objective of clarifying the toxic site of this unique pharmacological group, Bj-xtrIT was employed in a genetic approach using point mutagenesis and biological and structural assays of the mutant products. A primary target for modification was the structurally unique C-terminal region. Sequential deletions of C-terminal residues suggested an inevitable significance of Ile73 and Ile74 for toxicity. Based on the bioactive role of the C-terminal region and a comparison of Bj-xtrIT with a Bj-xtrIT-based model of a classical excitatory toxin, AaHIT, a conserved surface comprising the C terminus is suggested to form the site of recognition with the sodium channel receptor.  (+info)

Purification from black widow spider venom of a protein factor causing the depletion of synaptic vesicles at neuromuscular junctions. (2/601)

The aqueous extract of the venom glands of black widow spiders was fractionated on a column of Sephadex G-200 and then on a column of DEAE-Sephadex A-50 pH 8.2. A protein fraction was obtained that caused a great increase in the frequency of occurrence of miniature end plate potentials at the frog neuromuscular junction, and caused swelling of the nerve terminals and depleted them of their vesicles. The fraction consists of a least four protein components that are similar in their molecular weights (about 130,000) and isoelectric points (ranging from pH 5.2 to 5.5) and are immunologically indistinguishable. It contains no sugar residues and has little or no lipolytic or proteolytic activity. The fraction is toxic to mice and is different from the fractions that act on houseflies, the crayfish stretch receptor and the cockroach heart. It seems pure enough to warrant a detailed study of its site and mode of action.  (+info)

Contribution of potassium conductances to a time-dependent transition in electrical properties of a cockroach motoneuron soma. (3/601)

Contribution of potassium conductances to a time-dependent transition in electrical properties of a cockroach motoneuron soma. The cell body of the cockroach (Periplaneta americana) fast coxal depressor motoneuron (Df) displays a time-dependent change in excitability. Immediately after dissection, depolarization evokes plateau potentials, but after several hours all-or-none action potentials are evoked. Because K channel blockers have been shown to produce a similar transition in electrical properties, we have used current-clamp, voltage-clamp and action-potential-clamp recording to elucidate the contribution of different classes of K channel to the transition in electrical activity of the neuron. Apamin had no detectable effect on the neuron, but charybdotoxin (ChTX) caused a rapid transition from plateau potentials to spikes in the somatic response of Df to depolarization. In neurons that already produced spikes when depolarized, ChTX increased spike amplitude but did not increase their duration nor decrease the amplitude of their afterhyperpolarization. 4-Aminopyridine (4-AP) (which selectively blocks transient K currents) did not cause a transition from plateau potentials to spikes but did enhance oscillations superimposed on plateau potentials. When applied to neurons that already generated spikes when depolarized, 4-AP could augment spike amplitude, decrease the latency to the first spike, and prolong the afterhyperpolarization. Evidence suggests that the time-dependent transition in electrical properties of this motoneuron soma may result, at least in part, from a fall in calcium-dependent potassium current (IK,Ca), consequent on a gradual reduction in [Ca2+ ]i. Voltage-clamp experiments demonstrated directly that outward K currents in this neuron do fall with a time course that could be significant in the transition of electrical properties. Voltage-clamp experiments also confirmed the ineffectiveness of apamin and showed that ChTX blocked most of IK,Ca. Application of Cd2+ (0.5 mM), however, caused a small additional suppression in outward current. Calcium-insensitive outward currents could be divided into transient (4-AP-sensitive) and sustained components. The action-potential-clamp technique revealed that the ChTX-sensitive current underwent sufficient activation during the depolarizing phase of plateau potentials to enable it to shunt inward conductances. Although the ChTX-sensitive conductance apparently makes little contribution to spike repolarization, the ChTX-resistant IK,Ca does make a significant contribution to this phase of the action potential. The 4-AP-sensitive current began to develop during the rising phase of both action potentials and plateau potentials but had little effect on the electrical activity of the neuron, probably because of its relatively small amplitude.  (+info)

cDNA cloning of an adult male putative lipocalin specific to tergal gland aphrodisiac secretion in an insect (Leucophaea maderae). (4/601)

Lma-P22 is a cuticular surface protein specific to the tergal gland secretion of Leucophaea maderae adult males which is ingested by females just before copulation. The complete Lma-P22 cDNA sequence was determined by RT-PCR using primers based on Edman degradation fragments. The recombinant protein expressed in Escherichia coli was recognized by an anti-Lma-P22 antibody. Northern blot analysis indicates that the corresponding mRNA is transcribed only in the epidermis of male tergites. Sequence analysis indicated that Lma-P22 deduced protein belongs to the lipocalin family. Lipocalins are extracellular proteins which carry hydrophobic compounds and some of them can bind sexual pheromone in vertebrates. Lma-P22 is the first example of a lipocalin-like protein involved in insect sexual behavior.  (+info)

Clinical experience and results of a Sentinel Health Investigation related to indoor fungal exposure. (5/601)

This is a review of exposure conditions, clinical presentation, and morbidity of children and adults with indoor fungal exposure such as toxic Stachybotrys chartarum. Indoor exposure was characterized using different methods including microscopic, culture, cytotoxicity screening tests, and chemical analyses. Clinical case histories and physical and laboratory findings are presented of children (age < 18 years, n = 22; mean age 9 years; 60% females) and adults (age >18 years, n = 125; mean age 39 years, 67% females) who consulted an environmental health specialty clinic. In the pediatric patients' exposure history, widespread fungal contamination of water-damaged building materials with known toxic or allergic fungi was identified. Primarily disorders of the respiratory system, skin, mucous membranes, and central nervous system were reported. Some enumeration and functional laboratory abnormalities, mainly of the lymphatic blood cells, were observed, although no statistically significant differences were found. IgE or IgG fungi-specific antibodies, used as exposure markers, were positive in less than 25% of all tested cases. In an evaluation of a symptomatic girl 11 years of age (sentinel case investigation) living in an apartment with verified toxigenic fungi (i.e., S. chartarum), several health indicators showed improvement after exposure cessation.  (+info)

A K+ channel-blocking peptide from venom of Chinese scorpion Buthus martensii Karsch. (6/601)

AIM: To purify and characterize a potassium channel blocker (BmP-3) from the venom of Chinese scorpion Buthus martensii Karsch. METHODS: 1. Purification was carried out by gel-filtration, cation-exchange, and reversed-phase chromatographies. N-terminal was directly sequenced by double-coupling manual method. Molecular weight was determined on an electrospray ionization mass spectrometer. Amino acid composition was analyzed after acidic hydrolysis for 20 h in HCl 6 mol.L-1 at 110 degrees C. 2. Toxicity tests were conducted in mice and cockroaches. 3. The inhibitory effects of BmP-3 on K+ channels were tested in acutely dissociated rat hippocampal pyramidal neurons using whole-cell patch-clamp configuration. RESULTS: 1. A pure peptide (BmP-3, 8.1 mg) was obtained, about 0.08% of total proteins of the venom. The N-terminal sequences were VGCEE and the molecular weight was 2938 in ESI-mass spectra. 2. No death occurred at the dosage of 200 micrograms in mice and 8 micrograms in cockroaches. 3. The peptide at 10 mumol.L-1 reduced the peak outward K+ currents by 63% +/- 4% in vitro. CONCLUSION: BmP-3 inhibited K+ channels.  (+info)

Role of allergy in nasal polyps of Thai patients. (7/601)

As distinct from many countries, allergy in Thailand is of the perennial type which may play a role in the formation of nasal polyps. Forty consecutive patients with nasal polyps and 30 normal subjects as control were studied at the Allergy Clinic, Department of Otolaryngology, Pramongkutklao Hospital. A positive clinical history and skin allergy testing are diagnostic criteria for allergy. In the nasal polyps group, these were 28 males and 12 females, aged between 12-65 years, with an average age of 38.5 years. In the control group, there were 18 males and 12 females, aged between 15-53 yeas, with an average age of 34 years. All had received prick skin testing with 6 common aeroallergens. The prick skin test was considered positive when the wheal was > or = 3 mm with surrounding erythema. Twenty-four of 40 patients (60%) with nasal polyps had a positive prick skin test, while 6 in the 30 control cases (20%) had a positive prick skin test. This difference was statistically significant (P = 0.0019), Odd's ratio = 6.0 which means allergic persons were 6 times more prone to have polyps form than normal persons.  (+info)

Post-translational modifications of the insect sulfakinins: sulfation, pyroglutamate-formation and O-methylation of glutamic acid. (8/601)

We identified and chemically characterized the two major forms of sulfakinins from an extract of 800 corpora cardiaca/corpora allata complexes of the American cockroach, Periplaneta americana. Bioactivity during the purification was monitored by measuring heart beat frequency in a preparation in situ. By Edman degradation analysis and MS, these main forms were identified as having the primary structures Pea-SK [EQFDDY(SO(3)H)GHMRFamide] and Lem-SK-2 [pQSDDY(SO(3)H)GHMRFamide]. The sulfation was confirmed by UV, MS and peptide synthesis. In addition, post-translationally modified sulfakinins of both major forms were isolated and identified. Firstly, nonsulfated forms of these peptides are present in considerable amounts in the corpora cardiaca/allata. Secondly, the N-terminally blocked Pea-SK and the nonblocked Lem-SK-2 occur naturally in neurohaemal release sites. Thirdly, modified Pea-SK with O-methylated glutamic acid occurs which is not an artefact of peptide purification. The major forms of the sulfakinins were shown to be highly active on both the heart and hindgut with threshold concentrations of approximately 5 x 10(-10) M (heart) and 2 x 10(-9) M (hindgut).  (+info)

Within natural environments, animals must be able to respond to a wide range of obstacles in their path. Such responses require sensory information to facilitate appropriate and effective motor behaviors. The objective of this study was to characterize sensors involved in the complex control of obstacle negotiation behaviors in the cockroach Blaberus discoidalis. Previous studies suggest that antennae are involved in obstacle detection and negotiation behaviors. During climbing attempts, cockroaches swing their front leg that then either successfully reaches the top of the block or misses. The success of these climbing attempts was dependent on their distance from the obstacle. Cockroaches with shortened antennae were closer to the obstacle prior to climbing than controls, suggesting that distance was related to antennal length. Removing the antennal flagellum resulted in delays in obstacle detection and changes in climbing strategy from targeted limb movements to less directed attempts. A more ...

Cockroaches (or simply roaches) are insects of the order Blattodea. This name derives from the Latin word for cockroach, blatta.. Among the most well-known species are the American cockroach, Periplaneta americana, which is about 30 mm long, the German cockroach, Blattella germanica, about 15 mm long, the Asian cockroach, Blattella asahinai, also about 15 mm in length, and the Oriental cockroach, Blatta orientalis, about 25 mm. Tropical cockroaches are often much bigger, and extinct cockroach relatives such as the Carboniferous Archimylacris and the Permian Apthoroblattina were several times as large as these. Cockroaches are generally considered pests; however, only about 30 species (less than 1%) infest urban habitats.. Evolutionary history and relationships. The earliest cockroach-like fossils are from the Carboniferous period between 354-295 million years ago. However, these fossils differ from modern cockroaches in having long ovipositors and are the ancestors of mantids as well as ...
Cockroaches are oval and are flattened in appearance from top to bottom. Their heads are covered by a large, shield-like structure. They have two large eyes and two long antennae. With six long running legs attached to their thorax, they have been recorded at speeds up to three miles per hour.. In the adult cockroach wings may be present, absent or reduced, depending on the species. At the top of the abdomen cockroaches have a pair of jointed appendages, covered by specialized sensory hairs. These are used to detect air movement which can trigger an escape response.. The adult German cockroach is 10 to 15mm long. The Common or Oriental cockroach is 20 to 24mm long.. Cockroaches live in clusters. A pheromone causes them to cluster in harbourage areas such as cracks and crevices. This clustering helps illicit mating and helps in the survival chances of nymphal (infant) cockroaches. Cockroaches are frequently found indoors foraging for food, water and more suitable conditions.. In depth ...
Cockroaches leave chemical trails in their feces, as well as emitting airborne pheromones for swarming and mating. These chemical trails transmit bacteria onto surfaces. Other cockroaches will follow these trails to discover sources of food and water, and also discover where other cockroaches are hiding. Thus, cockroaches can exhibit emergent behavior, in which group or swarm behavior emerges from a simple set of individual interactions.. Cockroaches are generally omnivorous that basically mean that they can eat anything.. Cockroaches Control can be difficult in Sydney. By nature, cockroaches are survives that breed really quickly and that means that if you see a few crawling around they can easily become hundreds in a matter of weeks..

The cockroach can also harbour viruses.. ...
Cockroach feces are easy to identify. Droppings from small cockroaches resemble ground coffee or black pepper. Larger roaches leave behind dark, cylindrical droppings with blunt ends and ridges down the side.. With a closer look, homeowners can tell the difference between rodent and cockroach feces. Mouse and rat droppings have pointed ends, while cockroach poop does not.. Cockroaches are omnivores, and the pests are not fussy about where they get their meals. Garbage, sewage, carrion, and crumbs are all fair game. As a result, their digestive systems retain disease pathogens from anything theyve eaten. These microbes then leave the pests bodies within cockroach poop.. Like most insects, cockroaches dont concern themselves with bathroom hygiene. The pests defecate in or near whatever they eat. When cockroach droppings pollute pantries, kitchen surfaces, or poorly sealed food containers, all the bacteria the insect has consumed may be spread to people.. In addition to cockroach feces, the ...

Cockroaches are insects of the order Blattodea, which also includes termites. About 30 cockroach species out of 4,600 are associated with human habitats. About four species are well known as pests. The cockroaches are an ancient group, dating back at least as far as the Carboniferous period, some 320 million years ago. Those early ancestors however lacked the internal ovipositors of modern roaches. Cockroaches are somewhat generalized insects without special adaptations like the sucking mouthparts of aphids and other true bugs; they have chewing mouthparts and are likely among the most primitive of living neopteran insects. They are common and hardy insects, and can tolerate a wide range of environments from Arctic cold to tropical heat. Tropical cockroaches are often much bigger than temperate species, and, contrary to popular belief, extinct cockroach relatives and roachoids such as the Carboniferous Archimylacris and the Permian Apthoroblattina were not as large as the biggest modern ...

Cockroaches are known to be the most ancient insects to walk the planet, and they also happen to be the most stubborn to kill off. Cockroaches carry serious illnesses such as dysentery, typhoid, poliomyelitis and gastroenteritis as they can live on just about anything; including fermenting products, septic dressings, hair, leather, wallpaper, faeces and rotting food. And, they often breed in unhygienic areas.. Many of the substances that cockroaches feed on are already contaminated, as this creepy crawly insect moves from one location to another. Not only can people get sick from the bacteria with which cockroaches contaminate our living areas, but some people are actually allergic to cockroach faeces; inhaling it as small particles of dust, or ingesting it along with food (Planet Cockroach, 2012). Cockroach droppings can cause eczema and asthma, and the health risks are particularly high in homes containing children, the elderly or those fighting other illnesses.As a cockroach infestation in ...

Cockroaches undergo egg and nymphal stages before becoming adults. Eggs produced by female cockroaches are enclosed in resilient egg cases known as oothecae. The oothecae of cockroach species contain a range of nymph numbers which is dependent on species. The time it takes for eggs to hatch into nymphs varies between species as well and depends upon environmental conditions. Nymphs free themselves from the oothecae by working in concert.. Nymphs resemble adults in appearance and behavior, although they are smaller in size and do not have wings. Nymphs undergo a series of molts before becoming fully mature adults. After the final molt, nymphs of some cockroaches are equipped with wings. After nymphs molt, they are pale in color. Nymphal cockroaches that have recently molted are often misidentified as albino roaches. Within a few hours, they will darken to the proper color.. Adult cockroaches have an average lifespan of around a year but it depends on species. Temperature and other environmental ...
Cockroaches (Blattaria: Dictyoptera) harbor the endosymbiont Blattabacterium sp. in their abdominal fat body. This endosymbiont is involved in nitrogen recycling and amino acid provision to its host. In this study, the genome of Blattabacterium sp. of Cryptocercus punctulatus (BCpu) was sequenced and compared with those of the symbionts of Blattella germanica and Periplaneta americana, BBge and BPam, respectively. The BCpu genome consists of a chromosome of 605.7 kb and a plasmid of 3.8 kb and is therefore approximately 31 kb smaller than the other two aforementioned genomes. The size reduction is due to the loss of 55 genes, 23 of which belong to biosynthetic pathways for amino acids. The pathways for the production of tryptophan, leucine, isoleucine/threonine/valine, methionine, and cysteine have been completely lost. Additionally, the genes for the enzymes catalyzing the last steps of arginine and lysine biosynthesis, argH and lysA, were found to be missing and pseudogenized, respectively. ...
Eradication of cockroaches can be complicated and should be carried out by professional pest control operative. They are difficult to treat, their hiding places are often difficult to reach with insecticides and because of the efficiency of the breeding process and the large number of eggs produced, cockroaches are difficult to eradicate and a Comprehensive eradication program is essential. The first step is to monitor the level of the infestation. Inspections should be carried out at night, when the cockroaches are most active, using a torch with a red filter which cockroaches do not respond to. A high standard of hygiene is important in the control of cockroaches and involves refusing access to food and water. This will increase cockroach activity and directed movement increasing the chance of the insects coming across insecticides. Inspections should be carried out at night when the cockroaches are active.. Effective treatment would depend upon the selection and thorough application of an ...

The Oriental cockroach (also known as: waterbug and Blatta orientalis) is a large species of cockroach, measuring about 1 inch in length at maturity. It is dark brown to black in color and has a glossy body. The female Oriental cockroach has a somewhat different appearance to the male, appearing to be wingless at casual glance but has two very short and useless wings just below her head. She has a wider body than the male. The male has long wings, which cover a majority of his body and are brown in color, and has a more narrow body. The odd male is capable of very short flights, ranging about 2 to 3 feet. The female oriental cockroach looks somewhat similar to the Florida woods cockroach, and may be mistaken for it.. In order to thrive, cockroaches need a place to hide. They prefer warm places and a relatively high humidity if possible; they also need a source of food/liquid. The optimum temperature for oriental cockroaches is between 68 °F to 84 °F. Female oriental cockroaches have vestigial ...
Salmonella, E. coli, and other bacteria that cause food poisoning or gastroenteritis are the primary germs known to be spread by cockroaches (see Cockroaches in Your Food!). But cockroaches can also carry many other nasty germs such as plague, dysentery, typhoid fever, leprosy, even urinary tract infections. Almost any cockroach tested could be found to be carrying at least one disease organism on its body, but how real is the risk of a cockroach actually transmitting a disease to a person?. Cockroach transmission of diseases has been shown in the laboratory but proving transmission in the real world is problematic. Occasional localized outbreaks of hepatitis or typhoid have been attributed to the presence of disease-carrying cockroaches, but not directly proven. Perhaps its a testimony to our bodies ability to resist germs that cockroach-related disease outbreaks are not more common. Thats why its concerning that cockroaches in some hospitals have now been found to harbor ...

What You Can Do to Limit an Infestation of Cockroaches. Cockroaches are one of the most disgusting insects that infest peoples homes and offices. Not only do they hide well, they are nocturnal, which makes them hard to find. When a cockroach is seen in the home, there is certainly already an infestation. This is because, for every one that is spotted, there are possibly dozens that are unseen. They are also extremely allusive and tough insects, which makes exterminating them extremely difficult. Here, are 6 tips that can be used to limit an infestation of cockroaches.. Spring Cleaning. One way to limit the infestation of cockroaches is to do a thorough cleaning of the house. This should include the garage and the basement. Appliances should be moved and cleaned around; rugs should be lifted up. No area of the house should be left alone when cleaning. Remember, seeing two or three cockroaches and killing them will not even come close to freeing a house of cockroaches. When cleaning, remember to ...

According to John Bender from Case Western Reserve University, USA, cockroaches are great walkers and exceptionally stable when negotiating rugged terrain. It would be great to design robots that walk like cockroaches, but how do they control their legs? puzzles Bender. Curious to understand how the cockroach brains control their movements, Bender joined Roy Ritzmanns laboratory to begin studying how cockroaches walk.. Teaming up with engineers Brian Tietz, Kathryn Daltorio and Roger Quinn, Bender designed and built a large arena that the cockroaches could explore while the team recorded their antics (p. 2057). Then Bender calculated each insects route and speeds and was surprised that instead of moving over a continuum of speeds, the insects had two natural paces: a fast 30 cm s-1 trot and a slower 10 cm s-1 amble.. Next, we wanted to see what it was about the cockroach and the ...
To be honest, cockroaches are the worst type of passenger in every car and the nightmare bug. The spices will also naturally dissipate outdoors. Hang owls feather on walls or in the garden to stop a pack of mice. Thats the reason they form the basis … The roachs legs are covered with many thorns so its easy to stick to every kind of surface. Dont be scared / afraid / frightened. I dont like that insect being here, and (unfortunately) Im going to have to do something about it… Many types of cockroach have wings, and a few actually fly. You will need pesticide/lawn fertilizer sprayer to apply the pesticide and IGR that will put a stop to them. When you find German Roaches you will typically find them in groups of dozens if not hundreds of Roaches. Many children are afraid of / scared of / frightened of cockroaches and spiders. Common flying cockroaches include the Asian, Smokybrown, American, Australian and Pennsylvania Wood cockroaches. RELAX, THESE COCKROACHES ARE ALMOST ON THEIR WAY ...
Cockroaches are drawn to warm, damp and dark places, as well as areas close to foodstuffs. They will scatter from light, so getting a proper look at them can be hard, but there are a few signs that you can look out for.. Signs of an infestation can include smear marks or droppings left by the cockroaches as they move around, cast exoskeletons from their moults, egg cases, and oddly enough an almost almond-like smell. If you spot any of these signs, or any live cockroaches please contact us as soon as possible as this is a serious infestation that needs to be dealt with quickly.. The biggest problem with cockroaches is how quickly they can breed. Each female cockroach is able to make up to four hundred babies in their lifetime, with each baby reaching maturity within three months and living for another three to nine months after that. Of course, as soon as they reach maturity, these cockroaches are able to breed and the cycle starts again. Its incredibly easy for an infestation to quickly grow ...
Cockroaches are primitive insects that help recycling dead plant material outdoors. However the few species that infest our homes and businesses give all cockroaches a bad reputation. There are almost 70 kinds of cockroaches in the United States; but only six or so are considered pests of homes and businesses.. Fortunately, with the development of effective baits and safer sprays and dusts, cockroaches are not as difficult to control as they once were. However, these insects continue to be a problem in many households, where they can spread disease and produce allergens that can lead to asthma, especially in children. No one should have to live in a home with cockroaches. The following fact sheets provide useful information for controlling cockroaches.. ...
There are many types of cockroaches. The most popular types include; the American cockroach, the Australian cockroach, and the German cockroach. The German cockroach is the smallest and the most common species inside buildings. They are 12-15 mm and are to be found in food handling areas like the storerooms and kitchens. They cannot fly and mostly prefer areas near food, warmth, and moisture.. The Australian cockroach is larger than the German cockroach at 30-35 inches in length. It has a dark brown color and has yellow markings on the front wings and head. This type of cockroach unlike the German cockroach is to be found outdoors and prefers plant food. It is to be found among woodpiles and under the bark of trees.. The American cockroach is the largest cockroach measuring 30-45mm in length. It is red-brown in color and has a pale yellow border around the head. It can fly and prefers warm and moist conditions. It is very common in rubbish dumps, sewers, and drains..

We chose cockroaches as our study animal because template models have been developed for cockroach running (Holmes et al. [14] and references therein). We hope that by providing a numerical means for obtaining a template, we provide an empirical anchor-point to which existing and new theoretical models may be related. Cockroaches are large, easy to raise and state information in the form of leg posture is readily measured, suggesting cockroaches as a natural target for predictive models based on leg state.. We used two datasets collected with different experimental systems. Most of our analysis was done on kinematic data of cockroaches running on a transparent treadmill, and photographed from below through the treadmill belt [26,27]. Animals ran in the transparent arena of size 80 × 200 cm, while a robot tracked their movements using a high-speed camera with a zoom lens.. We used 34 adult Blaberus discoidalis cockroaches of both sexes (mass 3.3 ± 0.34 g; body length 49 ± 2.6 mm) in the ...
Learn how to identify different types of cockroaches in the U.S., including species like German cockroaches, Oriental cockroaches and American cockroaches.
Cockroaches are nocturnal by nature and spend the day hiding in cracks around areas like sinks, drains, cookers and the backs of service ducts. They may be seen if you come home in the dark and put the lights on. They also emit an unpleasant almond like smell - only noticeable if the infestation is large. The cockroach is a small species of cockroach, measuring about 1.3 cm to 1.6 cm (1/2″ to 5/8″) long.. It is tan to light brown, and has two dark parallel streaks running from the head to the base of the wings. Although it has wings, it is unable to sustain flight.Nymphs have a pale area centrally on the dorsal thorax. The cockroach is one of the most common and prominent household cockroaches in the world, and can be found throughout many human settlements in the world. These insects are particularly fond of inhabiting restaurants, food processing facilities, hotel rooms, and nursing homes. In colder climates, it is found only near human habitats. The German cockroach is originally from ...

Here are a few of their odd behaviors:. Attracted to beer and will eat anything. Watch out, cockroaches are attracted to alcoholic beverages, especially the hops and sugar found in beer. Be sure to clean up well and rinse out beer bottles or cans. Also, these scavengers will thrive on just about anything, including wallpaper paste, hair, and garbage. Even more unbelievable is that cockroaches can go for as long as six weeks without a meal! At least these scavengers do us a favor by consuming organic waste.. Can live for a week without a head. Cockroaches can live for a week without their heads because they have open circulatory systems, and breathe through spiracles, or holes in their body segments. They eventually die of dehydration, without their mouths to drink, or die from mold.. Cockroaches scurry quickly. Its hard to believe. But even a baby cockroach the size of a dirt speck can keep up. Cockroaches can run up to three miles per hour, and turn quickly even while in full stride. So act ...

There are three basic steps to preventing a cockroach infestation in your restaurant:. Step One: Maintain Proper Sanitation. Avoiding cockroaches and other pests in your restaurant starts with sanitation. Create schedules for the crew for daily cleaning of trash bins, floors, sinks, and kitchen equipment. A very thorough cleaning should be completed when the restaurant closes each night.. Step Two: Inspection. Inspecting your restaurant regularly will give you an idea where pests could be harboring and help you decide if you need to use insecticide applications and where to use them. Look closely at any area that could be a hiding spot for pests. Rodents, cockroaches, and flies will generally leave behind evidence that theyve been in a certain area - such as feces, egg cases, or skins. Inspect trash bins, floor drains, sinks, and all kitchen equipment and tubing on appliances where rodents or insects could hide. If you suspect an infestation of cockroaches or any other pest, place glue boards ...
The Central American giant cave cockroach (Blaberus giganteus) is a cockroach belonging to the family Blaberidae. B. giganteus is considered one of the largest cockroaches in the world, with males growing to reach lengths of 7.5 cm and females 10 cm. These cockroaches are lightly built with flattened bodies, allowing them to hide in cracks from predators. Their bodies are brown with black markings. The wingspan of these insects is usually 5-6 in. Both males and females bear paired appendages (cerci) on the last abdominal segment, but only the males have a pair of tiny hair-like appendages called styli. Adults bear two pairs of wings folding back over the abdomen. The heavier females are less likely to fly. These cockroaches are closely related to the first winged insects that lived in the Carboniferous coal forests about 200 million years ago. [better source needed] This species is endemic to Central America and northern South America, and can be found in the rainforests, in Mexico, Guatemala, ...

Cockroaches are terrestrial insects that strikingly eliminate waste nitrogen as ammonia instead of uric acid. Blattabacterium cuenoti (Mercier 1906) strains Bge and Pam are the obligate primary endosymbionts of the cockroaches Blattella germanica and Periplaneta americana, respectively. The genomes of both bacterial endosymbionts have recently been sequenced, making possible a genome-scale constraint-based reconstruction of their metabolic networks. The mathematical expression of a metabolic network and the subsequent quantitative studies of phenotypic features by Flux Balance Analysis (FBA) represent an efficient functional approach to these uncultivable bacteria. We report the metabolic models of Blattabacterium strains Bge (iCG238) and Pam (iCG230), comprising 296 and 289 biochemical reactions, associated with 238 and 230 genes, and 364 and 358 metabolites, respectively. Both models reflect both the striking similarities and the singularities of these microorganisms. FBA was used to analyze the
order Pregabalin online uk The next revolutionary gaming app? Maybe someday. But to the emerald wasp, this grisly battle is a routine part of its everyday life.. For decades, scientists have tried to understand the complex and gruesome relationship between the parasitic emerald wasp (Ampulex compressa) and its much larger victim, the common household cockroach (Periplaneta americana).. At first glance, this parasite-prey relationship seems much like any other: the female wasp stings the cockroach, lays an egg on its abdomen, and once hatched, the hungry larva feeds on the cockroach. However, while most parasitic insects tend to paralyse their victims with a venomous sting, the emerald wasp instead does something a lot more interesting - it manipulates the cockroachs behavior, essentially transforming it into a zombie slave.. With two stings the cockroach is left with the ability to walk, but is entirely robbed of the power to initiate its own movement. The wasp, now tired after administering ...

This is a male Wood Cockroach, and it will not infest your home, but they are attracted to lights. We suspect it is a Pennsylvania Wood Cockroach, Parcoblatta pennsylvanica, based on this BugGuide image. According to the Colonial Pest Control Blog: You may have already figured out that you are more likely to be visited by wood roaches if you live in a wooded area. These cockroaches are common in woods where they feed on decaying organic matter. Around homes, wood roaches can sometimes be found in gutters, potted plants, under cedar shake or other wood siding, or in firewood. Wood cockroaches are seldom seen except during their mating season which lasts from late May into June in our area. ...

The German cockroach has three life stages typical of insects with incomplete metamorphosis: the egg, nymph, and adult. The entire life cycle is completed in about 100 days. However, factors such as temperature, nutritional status, and strain differences may influence the time required to complete a life cycle. German cockroaches breed continuously with many overlapping generations present at any one time. Under ideal conditions, population growth has been shown to be exponential. Actively growing field populations are comprised of 80 percent nymphs and 20 percent adults. The German cockroach is omnivorous, eating table scraps, pet food, and even book bindings. ...
The American cockroach was introduced to the United States from Africa as early as 1625. They belong to the Kingdom: Animalia, Phylum: Arthropoda, Class: Insecta (Insecta: Blattodea: Blattidae), Order: Dictyoptera, and Family: Blattidae. Its common name is American cockroach and scientific name is Periplaneta Americana (Linnaeus). American cockroaches are normally between one and one and a half inches in length. They are oval shaped and reddish-brow with yellow fringes on the area of the body behind the head as adults. They hide in dark crevices during the day, which could include: sewer and drainage systems, cracks and crevices of a house, steam tunnels, large institutional buildings and basements. They emerge at night to hunt for food. Theyll eat pretty much anything. Although it prefers sweets, they have been observed eating paper, boots, hair, bread, fruit, book bindings, fish, peanuts, old rice, putrid sake, the soft part on the inside of animal hides, cloth and dead insects.

Lipophorin receptors (LpRs) have been described in a number of insects, but functional studies have been reported only in locusts and mosquitoes. The aim of the present work was to characterize the LpR of the cockroach Blattella germanica, not only molecularly but also functionally using RNAi techniques, and to place LpRs in a phylogenetical context among lipoprotein receptors. We cloned a putative LpR from B. germanica (BgLpR) using RT-PCR methods. Two isoforms of BgLpR that differ from each other by an insertion/deletion of 24 amino acids were obtained from the fat body and the ovary. A phylogenetical analysis of lipoprotein receptors showed that BgLpR grouped with other sequences annotated as LpR in a cluster placed as a sister group of vertebrate low density lipoprotein receptors (LDLR) + lipoprotein receptor-related proteins 8 (LPR8) + vitellogenin receptors (VgR) + very low density lipoprotein receptors (VLDLR). The two BgLpR isoforms are expressed in different adult female tissues (fat body,
Blattabacterium strain Bge is the primary endosymbiont of the cockroach Blattella germanica. It is a Gram-negative maternally inherited bacteria which lives in specialized cells in the hosts abdominal fat body. Phylogenetic analyses for the Blattabacterium-cockroach symbiosis supports the hypothesis of co-evolution between symbionts and hosts dating back to more than 140 million years ago. Cockroaches are omnivorous insects, often subsisting on a nitrogen-poor diet, and Blattabacterium have been hypothesized to participate in uric acid degradation, nitrogen assimilation, and nutrient provisioning. Genome sequencing and metabolic reconstruction shows that Blattabacterium can recycle nitrogen from urea and ammonia, which are uric acid degradation products, into glutamate, using urease and glutamate dehydrogenase, and thus would be able to provide its host with some essential amino acids, vitamins and cofactors. The bacterium relies on Pro, Gln and Asn supplied by the host. It encodes the complete ...
Scientists say there are 4500 specials of cockroaches in the world, but just 30 species are considered pests. However, four of those pesky species create havoc or at least heart palpitations in North America: the German, American, Australian, and Oriental cockroaches.. The German cockroach is the most common and the most prolific breeder in America. Each egg sack contains 30-40 nymphs.. The American cockroach is the largest of the pest species, often scaring people as it scurries across the floor. They dont bite.. The Australian roaches are a bit smaller than the American cockroach but seem quite adept at randomly flying or walking along the ceiling.. The Oriental cockroaches are small and frequently found near water/wet areas such as gutters, sewers and pipes. They particularly like feeding on garbage or materials that have begun to decay. These pests, often called water bugs, do not have wings, are black to dark reddish-brown in color, and gain entry beneath the thresholds of doors, gaps ...

A lot of people are thinking that because winter is here, homes may be spared from pests. But the truth is, different bugs are around and active during winter. A particular pest that many are curious about is the appearance of the winter proof cockroach, or the periplaneta japonica.. The Periplaneta japonica is commonly found in Asia, but unfortunately, has found its way into the United States, particularly in New York. They were first met in 2012 in a park in New York by an exterminator who knew he had found a new breed of cockroach. The cockroaches were later sent to the University of Florida to be analyzed.. While there are still insufficient studies as to how these winter-proof cockroaches can affect other cockroach species, or how well they can disturb homes and businesses, most are not looking forward to the periplaneta japonica becoming a permanent resident in the U.S. One particular reason for the low enthusiasm for this breed is because their nymphs are also able to survive in snow for ...

Boric acid is a white powder is made from water and the mineral boron. Boron is widely used in laundry products and in personal products such as toothpaste, and boric acid is sold in grocery stores as bug killer, ready to use. Dust it where cockroaches like to hide: in cracks and corners, under and behind fixtures and appliances. Spread the powder thinly, as cockroaches avoid piles or heavy lines. Theyll pick up the powder as they walk through it and poison themselves when they clean it from their antennae and legs.. You can also try roach baits. Commercially available cockroach baits also kill the pests without triggering more allergies, or endangering people or pets. The roaches crawl into the plastic cover, eat the bait and then crawl away to die in their nesting area, where the bait will kill fellow roaches. Put baits in areas roaches like, especially in kitchens and bathrooms.. ...

In a well-documented example of external parasite control, an emerald cockroach wasp (Ampulex compressa) enslaves a much larger cockroach (Periplaneta americana). The wasp injects a neurotoxin into the cockroachs brain. This toxin kills off the roachs ability to control its own movement but doesnt paralyze it entirely. The wasp is then able to grasp the roachs antenna and lead it into a nest before laying an egg in the live cockroachs body ...

We are interested in the regulation of metamorphosis not only from a developmental point of view but also from an evolutionary perspective. As most information has been obtained in holometabolan species (mainly in the fly Drosophila melanogaster and the beetle Tribolium castaneum), we focus our research on the cockroach Blattella germanica, a phylogenetically basal species showing a gradual metamorphosis that might be close to the ancestral hemimetaboly. We aim at elucidating the mechanisms that regulate metamorphosis in B. germanica and then to compare them with those operating in holometabolans. The idea is to infer the evolutionary history underlying the transition from hemimetaboly to holometaboly ...

This is the first molecular phylogenetic study comprehensively comparing trichonymphid flagellates between Cryptocercus and termites. The results indicate that Cryptocercus symbionts probably have a sister-group relationship to the corresponding symbionts of termites in each group of Trichonymphida. The nesting of Cryptocercus symbionts within clades of corresponding termite symbionts was rejected. Since the host Cryptocercus is phylogenetically sister to termites, the results strongly suggest that a set of trichonymphid flagellates that correspond to ancestors of extant Trichonymphidae, Hoplonymphidae and Eucomonymphidae plus Teranymphidae was established in the common ancestor of the hosts and vertically transmitted to offspring. One line of evidence supporting this hypothesis is that species in the genus Trichonympha, one of the few genera common to Cryptocercus and termites, are clearly differentiated. Trichonympha cells in Cryptocercus all possess a nuclear sleeve that is absent in termite ...
The ability of the Blattella germanica to respond to immunological stimulations is limited when compared to that of the mammalian system. Granulocytes are a basic blood cell type found in most animals; in humans these cells divide and differentiate into basophils, eosinophils, and neutrophils, among others. These cells make up a small portion of the total blood cells found in mammals. In the German cockroach, however, the granulocyte is the most predominate blood cell type, making up 94% of the total cell count. Since this cell was overwhelmingly prevalent in the cockroach, it was studied to determine how many antigenic surface receptors it contained on its membrane. The study began by injecting New Zealand rabbits with granulocytes, isolated from the German cockroach to stimulate antibody production. Using rabbit antigranulocytes serum for Western blot analysis, seven antigenic surface determinants were identified and their molecular weights were determined.
Three out of four hospital kitchens in Britain have breached basic food hygiene standards, a damning investigation by The Sunday Times can reveal. At least 13 kitchens were found to be infested by rodents or cockroaches, while others were risking the health of already ill patients by storing food incorrectly or well beyond its use-by date. An analysis of more than 700 environmental health inspections at both NHS and private hospitals shows: - Two species of cockroach - german and oriental - were identified last month near the coffee shop and in a basement corridor at Barts hospital in London. It also had mice ...
mAb DSS-8 binds to a 164-kD developmental stage-specific cell surface antigen in the nervous system of the cockroach, Periplaneta americana. The antigen is localized to different subsets of cells at various stages of development. The spatial and temporal distributions of DSS-8 binding were determined and are consistent with this antigen playing multiple roles in the development of the nervous system. Direct identification of some of these functions was made by perturbation experiments in which pioneer axon growth occurs in embryos that are cultured in vitro in the presence of mAb DSS-8 or its Fab fragment. Under these conditions the pioneer axons of the median fiber tract grow but follow altered pathways. In a smaller percentage of the ganglia, the immunoreagents additionally produce defasciculation of a subset of DSS-8 labeled axons. Therefore, direct roles for the DSS-8 antigen in both the guidance of pioneer axons and selective fasciculation have been demonstrated. ...
The Cockroach Bay Ecosystem Restoration Project represents one of the largest, most complex coastal ecosystem restoration projects ever developed for Tampa Bay. The 20-year restoration project was initiated and managed by the Hillsborough County Parks, Recreation and Conservation Department and the Southwest Florida Water Management Districts Surface Water Improvement and Management Program. Before the restoration, this area suffered from a number of environmental problems including habitat degradation, invasive plant infestation and poor water quality. Hillsborough County purchased the Cockroach Bay property in 1991. Planning began immediately and work soon started to restore 500 acres of wetlands, uplands and coastal habitats. Stormwater treatment and agricultural runoff also were improved as part of the restoration.. The final phase of the project included restoring two shell pits, funded by the Tampa Port Authority. The completion of this work in 2012 marked the successful end of the ...
In their latest attempt to convince squeamish Western palates that insects are edible food sources, Danish chefs from a culinary research center have released a video in which they boil, slice and sauté a fat, juicy cockroach and serve it up for breakfast.. Uploaded this week, the latest video from the Nordic Food Lab led by world-renowned Copenhagen restaurant Noma, shows chefs dropping a large, hard-shelled cockroach, supposedly fed on split peas, black currants and chamomile, into a pot of boiling water.. The specimen is then split open, and added to a pan of what appears to be slices of simmering root vegetables (details are sparse).. But even the chefs who cooked it seem trepidatious about sampling their latest concoction as the video shows them taking dainty bites.. Its the latest video out of the Nordic Food Lab in the lead-up to a London dinner party at the Pestival Festival at the end of the month, an annual event that pays homage to our multi-legged, winged and bug-eyed ...

Reptiles Alive Name: Too many to name. Hissstory: Our first few hissing roaches were donated to us by Long Branch Nature Center in Arlington, VA. Within a few months, we had lots, lots more.. RA Diet: Chopped leafy greens, vegetables, monkey chow, dog food, fruit, leftovers. (Hey, they are roaches they like leftovers!). Natural Diet: Roaches are scavengers - they will eat dead and decaying plants and animals laying on the forest floor.. Range: Madagascar. Habitat: Hissing roaches live in the tropical rain forests of Madagascar.. Size: Hissing roaches are a relatively a large roach, growing to about 3 inches.. Lifespan: Hissing roaches live for about two years.. Reproduction: Male hissing roaches have two large bumps on the tops of their heads. They use them to battle for females just like goats do. After mating, females will keep the eggs inside her body until they hatch. Gestation is 60-70 days. Females have about 30 young.. Conservation: Cockroaches are one of the most important species on our ...
The weaker, shorter bites were generated by relatively fast muscle fibers, while the longer, stronger bites were driven by additional muscle fibers that take time to reach their maximum force, said lead researcher Dr. Tom Weihmann of Cambridge University. These slower muscle fibers give the mandibles a force boost to allow them to exert up to 0.5 Newtons during sustained grasping or chewing.. The employment of slow muscle fibers allows very efficiently generated muscle forces with only a minimum of cross section area, and therefore head volume, required.. Scientists are interested in studying animal superpowers like this in the hopes of discovering new techniques to create more powerful machines for humans. Engineers could incorporate the cockroachs technique to make small, strong motors or perhaps even very small surgical equipment.. As insects play a dominant role in many ecosystems, understanding the amount of force that these insects can exert through their mandibles is a pivotal step ...

DNA analysis from 16S rRNA sequences has supported a hypothesis, originally suggested by Cleveland and colleagues in 1934, that these insects are most closely related to the wood-eating cockroaches (genus Cryptocercus, the woodroach). This earlier conclusion had been based on the similarity of the symbiotic gut flagellates in the wood-eating cockroaches to those in certain species of termites regarded as living fossils. In the 1960s additional evidence supporting that hypothesis emerged when F. A. McKittrick noted similar morphological characteristics between some termites and Cryptocercus nymphs. These similarities have led some authors to propose that termites be reclassified as a single family, Termitidae, within the order Blattodea, which contains cockroaches. Other researchers advocate the more conservative measure of retaining the termites as Termitoidae, an epifamily within the cockroach order, which preserves the classification of termites at family level and below.. The oldest ...
