Evidence for suppressed activity of the transcription factor NFAT1 at its proximal binding element P0 in the IL-4 promoter associated with enhanced IL-4 gene transcription in T cells of atopic patients. (1/644)

Allergen-specific T cells in atopic patients are polarized IL-4-producing Th2 cells, promoting IgE synthesis by B cells. The molecular basis for increased IL-4 gene expression in atopy is not fully understood. IL-4 gene regulation in general involves the nuclear factor of activated T cells (NFAT) family of transcription factors, of which NFAT1 and NFAT2 are most prominent in peripheral T cells. Recently, a unique inhibitory role of NFAT1 in IL-4 gene control was shown in the mouse. In a series of electrophoretic mobility shift assays with protein extracts of highly polarized Th2 clones from atopics and Th1 clones from controls we compared DNA-binding activities at the two NFAT-binding elements P0 and P1 of the crucial proximal human IL-4 promoter. At the most proximal P0 site, NFAT-containing complexes devoid of NFAT2 were readily inducible in the Th1 clones, but hardly or not in the Th2 clones. In contrast, both in Th1 and Th2 clones NFAT-containing complexes were strongly inducible at the P1 site, consisting of NFAT2 and a P0-compatible NFAT activity, without apparent differences between Th1 and Th2 clones. Like in Th2 clones, suppressed NFAT-P0 complex formation was observed also at the polyclonal level in peripheral blood mononuclear cells (PBMC) of three of five severe atopic dermatitis patients with strongly elevated serum IgE levels, but not in control PBMC. These findings suggest that high-level IL-4 production in atopic Th2 cells is associated with selective reduction of suppressive NFAT1 activity at the IL-4 P0 element and that some patients with this multifactorial disease may have a putative systemic disorder at this level.  (+info)

Role of the indoor environment in determining the severity of asthma. (2/644)

Allergen exposure can confound the management of asthma. To understand the potential mechanisms by which allergens increase the steroid requirements in atopic asthmatics, we examined the effects of allergens on glucocorticoid receptor (GCR) binding affinity and glucocorticoid (GC) responsiveness of peripheral blood mononuclear cells (PBMC) from atopic asthmatics. A significant reduction (p < 0.001) in the GCR binding affinity (Kd) was observed in ragweed-allergic asthmatics during ragweed pollen season compared with PBMC obtained before and after ragweed season. In vitro effects of allergen on PBMC GCR Kd were also examined by incubating PBMC from atopic asthmatics with allergen (ragweed and cat) versus Candida albicans. GCR binding affinity was significantly reduced after incubation with ragweed (p < 0.001) or cat allergen (p < 0.001) compared with baseline or C. albicans stimulation. This effect was limited to atopic asthmatics in that in vitro cat allergen incubation for 48 h failed to significantly alter GCR binding affinity in nonasthmatic, atopic individuals. These allergen-induced reductions in GCR binding affinity also rendered the PBMC less sensitive to the inhibitory effects of hydrocortisone and dexamethasone on allergen-induced proliferation (p < 0.01). To test the hypothesis that allergen-induced alterations in GCR binding affinity were cytokine-induced, we examined the effects of interleukin-2 (IL-2) and IL-4 neutralization using anticytokine antibodies. Addition of both anti-IL-2 and anti-IL-4 antibodies resulted in a significant (p < 0.001) inhibition of allergen-induced alterations in GCR binding affinity. Furthermore incubation with cat allergen induced significantly higher concentrations of IL-2 (p = 0.03) and IL-4 (p = 0.02) by PBMC from atopic as compared with nonatopic subjects. Our current observations suggest that allergen exposure may contribute to poor asthma control by reducing GCR binding affinity in mononuclear cells. This appears to be mediated through IL-2 and IL-4. These findings may have important implications for novel approaches to the treatment of poorly controlled asthma.  (+info)

Effect of dampness at home in childhood on bronchial hyperreactivity in adolescence. (3/644)

BACKGROUND: Relatively little is known about risk factors for the persistence of asthma and respiratory symptoms from childhood into adolescence, and few studies have included objective measurements to assess outcomes and exposure. METHODS: From a large cross sectional study of all 4th grade school children in Munich (mean age 10.2 years), 234 children (5%) with active asthma were identified. Of these, 155 (66%) were reinvestigated with lung function measurements and bronchial provocation three years later (mean age 13.5 years). RESULTS: At follow up 35.5% still had active asthma. Risk factors for persisting asthma symptoms in adolescence were more severe asthma (OR 4.94; CI 1.65 to 14.76; p = 0.004) or allergic triggers (OR 3.54; CI 1.41 to 8.92; p = 0.007) in childhood. Dampness was associated with increased night time wheeze and shortness of breath but not with persisting asthma. Risk factors for bronchial hyperreactivity in adolescence were bronchial hyperreactivity in childhood (p = 0.004), symptoms triggered by allergen exposure (OR 5.47; CI 1.91 to 25.20; p = 0.029), and damp housing conditions (OR 16.14; CI 3.53 to 73.73; p < 0.001). In a subgroup in whom house dust mite antigen levels in the bed were measured (70% of the sample), higher mite antigen levels were associated with bronchial hyperreactivity (OR per quartile of mite antigen 2.30; CI 1.03 to 5.12; p = 0.042). Mite antigen levels were also significantly correlated with dampness (p = 0.05). However, the effect of dampness on bronchial hyperreactivity remained significant when adjusting for mite allergen levels (OR 5.77; CI 1.17 to 28.44; p = 0.031). CONCLUSION: Dampness at home is a significant risk factor for the persistence of bronchial hyperreactivity and respiratory symptoms in children with asthma. This risk is only partly explained by exposure to house dust mite antigen.  (+info)

Sensitivity and exposure to indoor allergens in adults with differing asthma severity. (4/644)

In asthma, it is uncertain whether there is an association between degrees of exposure to domestic allergens and asthma severity. The pattern of sensitivity and exposure to common indoor allergens was examined in subjects with differing asthma severity. Sensitivity to house dust mite, dog and cat allergen and exposure to Der p 1, Can f 1 and Fel d 1 were assessed by skin prick tests and settled dust analysis in 28 subjects with severe asthma and 28 age- and sex-matched subjects with mild asthma (two declined skin prick test). All severe asthmatic subjects had at least one positive skin test and 20 of the 28 subjects were positive to all three allergens. Fourteen of the 26 subjects with mild asthma who took skin prick tests were positive to at least one, and one of these subjects was positive to the three allergens tested. Except for bedroom Fel d 1, the proportion of severe asthmatics both sensitized and exposed to each allergen at each site was significantly greater than the proportion sensitized and exposed in the mild asthma group. The geometric mean allergen concentrations, with the exception of bedroom Fel d 1, were greater in sensitized severe asthmatics than the sensitized mild asthmatics, which was significant for Der p 1 in bedroom samples and Can f 1 in bedroom and living room samples. These results support an association between the degrees of domestic allergen exposure in sensitized individuals and asthma severity.  (+info)

Production of recombinant Der fI (a major mite allergen) by Aspergillus oryzae. (5/644)

Der fI is a major mite allergen. To produce Der fI by Aspergillus oryzae, we placed a DNA fragment encoding precursor-type recombinant Der fI E(-1)K (reDer fI E(-1) K), which had the C-terminal amino acid of the pro-sequence (Glu) changed to Lys, downstream of the glaA gene promoter and introduced it into Aspergillus oryzae. In liquid culture, most of the reDer fI E(-1)K produced by the transformants was degraded when culture was shaken vigorously. However, the degradation of reDer fI E(-1)K was suppressed when it was shaken gently. The processed reDer fI E(-1)K could be obtained after lysylendopeptidase and endoglycosidase Hf (Endo Hf) treatment. The yield of processed reDer fI E(-1)K was 8 mg/l. When the transformant was grown on a wheat bran culture, the yield of processed reDer fI E(-1)K reached 48 mg/kg. Because processed reDer fI E(-1)Ks obtained from both cultures had almost the same IgE-binding activity and elicited the same skin reaction as native Der fI, they could be very useful for diagnostic purposes or immunotherapy.  (+info)

IPD-1151T (suplatast tosilate) inhibits interleukin (IL)-13 release but not IL-4 release from basophils. (6/644)

The effect of suplatast tosilate (IPD-1151T), which is known to suppress interleukin (IL)-4 release from T cells, on the release of IL-4 and IL-13 from human peripheral basophils was investigated. Basophils were obtained from 16 mite-sensitive atopic asthmatic patients. IPD-1151T clearly inhibited the antigen-induced release of IL-13 but not IL-4. These results suggest that IPD-1151T possesses different activity for the regulation of cytokine release in basophils and T cells.  (+info)

A healthy home environment? (7/644)

Over the past seven years, the U.S. Environmental Protection Agency has consistently ranked indoor air pollution among the top five risks to public health. One of the most dangerous indoor air pollutants is carbon monoxide (CO). CO can be lethal, but perhaps more important, many people suffer ill health from chronic, often undetected exposure to low levels of this gas, resulting in fatigue, headache, dizziness, nausea, and vomiting. Another dangerous pollutant is volatile organic compounds (VOCs), which come from sources including building products, cleaning agents, and paints. One VOC, formaldehyde, can act as an irritant to the conjunctiva and upper and lower respiratory tract. Formaldehyde is also known to cause nasal cancer in test animals.  (+info)

Cloning and expression of Der f 6, a serine protease allergen from the house dust mite, Dermatophagoides farinae. (8/644)

House dust mite allergen is thought to be a major cause of asthma. Characterization of these allergen molecules is therefore an important step for the development of effective diagnostic and therapeutic agents against mite-associated allergic disorders. Here we report molecular cloning and expression of the group 6 (chymotrypsin-like) allergen from the house dust mite, Dermatophagoides farinae. Sequencing analysis indicates that cloned cDNA, designated Der f 6, encodes a 279 amino acid polypeptide which conserves a primary structure characteristic for chymotrypsin-like serine proteases found in mammals. Recombinant Der f 6 expressed in Escherichia coli bound IgE in a pool made of 20 sera, and induced histamine release from patients' peripheral blood cells.  (+info)

BACKGROUND: The aim of this study was to estimate the prevalence of IgE-mediated allergy to Lepidoglyphus destructor and its clinical importance in Reykjavik, Iceland. METHODS: All Icelandic participants in the European Community Respiratory Health Survey in Reykjavik and suburbs were skin prick tested (SPT) for L. destructor. They also participated in a structured interview including questions about exposure to hay and symptoms related to hay exposure. Spirometry and methacholine tests were also performed. RESULTS: Altogether, 540 individuals underwent SPT with 12 allergens. Among them, 137 (25.4%) had positive skin tests, defined as at least one mean wheal reaction of , or =1 mm. By this definition, 34 (6.3%) were positive to L. destructor. These 34 individuals were significantly (P , 0.001) more often allergic to D. pteronyssinus (24/34), grass (14/34), cat (13/34), dog (12/34), Alternaria (11/34), Cladosporium (9/34), horse (8/34), and olive (8/34) than those not allergic to L. destructor. ...

Abstract Background Shrimp and house dust mite (HDM) allergies are common in Canadians. Often, both of these allergies occur in the same patient. This may be due to homology of tropomyosin or other potentially shared proteins. The aim of our study was to assess the frequency of house dust mite sensitization in a shrimp allergic Canadian population. Methods We undertook a retrospective chart review of shrimp allergic patients at an outpatient allergy clinic in Kitchener, Ontario, Canada. Our primary endpoint was to assess for presence of HDM sensitization in this population. Patients were categorized into approximate quartiles. We assessed the severity of the shrimp reactions, correlated shrimp skin test size to HDM skin test size, and measured the proportion of patients with atopic symptoms. Results We identified 95 shrimp allergic patients who were tested for house dust mite. 86 (90.5%) of these patients had a positive skin test to HDM. Patients with a shrimp skin test ≥5 mm were 5.31 times ...
Coloured scanning electron micrograph (SEM) of Dust mites (Dermatophagoides sp.) on wool fabric. Millions of dust mites inhabit the home, feeding on dead human skin that are common in house dust. The mites body is in three parts: the gnathosoma (head region) adapted for feeding on dead skin, the propodosma (carrying the 1st and 2nd pair of walking legs) and the hysterosoma (locating the 3rd and 4th pairs of legs). Dust mites produce 10-20 waste particles per day. The dead bodies and faecal pellets can trigger allergic responses. The whole life cycle from egg to adult takes approximately one month to complete, mature female mites can lay from 1-2 eggs per day. Adult mites can live up to two months. The most important house dust mites worldwide are Dermatophagoides farinae and Dermatophagoides pteronyssinus.

Sensitization to house dust mites (HDM) is highly prevalent among the young atopic population in Singapore. Previously published data suggest that individuals with skin allergies show preferred sensitization to Dermatophagoides pteronyssinus while individuals with pure respiratory allergies show preferred sensitization to Blomia tropicalis. The aim of our study was to compare the sensitization profiles between children with asthma and those with eczema to D. pteronyssinus and B. tropicalis and their specific allergens. A total of 60 children, 30 with asthma and 30 with eczema were recruited. IgE levels specific for a panel of HDM allergens from the two mite species were measured using enzyme-linked immunosorbent assay. The asthma group showed highest sensitization to Blo t5 while the eczema group showed highest sensitization to Der p5. Comparison between the two disease groups showed that the eczema group had significantly higher IgE levels for Der p (p=0.042) and its allergens Der p1 (p=0.019) ...
Some mites parasitize animals, including man; others are scavengers. Some mites feed on plants, and many prey on insects and other arthropods. In fact, there are nearly as many different types of mites as there are insects. Rodent and bird mites may bite people when they jump onto people. Three types of rodent mites readily bite humans: the house mouse mite (Liponyssoides saguineus), spiny rat mite (Laelaps echidnina) and tropical rat mite (Ornithonyssus bacoti).. The house mouse mite has a worldwide distribution but is more common in the northeastern United States. The house mouse mite normally sucks the blood of mice, but will also bite rats and people, often causing a rash around the bite. These mites prefer warm places where rodents live. The spiny rat mite feeds on rats at night and hides by day in cracks and crevices around rat nests and resting places. The spiny rat mite is the most common mite occurring on Norway rats and roof rats in the U.S. It is not a known vector of pathogens. The ...
Mites that infest and parasitize domestic animals cause disease and loss of production. Mites are small invertebrates, most of which are free living but some are parasitic. Mites are similar to ticks and both comprise the order Acari in the phylum Arthropoda. Mites are highly varied and their classification is complex; a simple grouping is used in this introductory article. Vernacular terms to describe diseases caused by mites include scab, mange, and scabies. Mites and ticks have substantially different biology from, and are classed separately from, insects (the class Insecta). Mites of domestic animals cause important types of skin disease, and some mites infest other organs. Diagnosis of mite infestations can be difficult because of the small size of most mites, but understanding how mites are adapted to feed within to the structure of the skin is useful. The life-cycle of mites begins with eggs are laid on the vertebrate animal host or within the nest or environment of the host. From the egg ...

Seven trials satisfied the inclusion criteria. Of these, only two studies investigating the effectiveness of mite impermeable bedding covers were of good quality; the remaining five studies were small and of poor quality. Two trials investigated the efficacy of acaricides, another two trials investigated the role of high-efficiency particulate air filters; the remaining three trials investigated the efficacy of bedroom environmental control programmes involving use of house dust mite impermeable bedding covers. Six of the seven trials showed that the interventions result in significant reductions in house dust mite load when compared with control. Of the house dust mite interventions studied to date, acaricides appear to be the most promising type of intervention, although the findings from the two studies which employed these interventions need to be interpreted with care because of their methodological limitations. Use of house dust mite impermeable bedding as an isolated intervention is ...
Dust mites are a common cause of allergy problems. Dust mites live up to 4 months. Each female can lay 100 eggs. Dust mites eat dead skin flakes and produce waste called fecal pellets. One mite may produce 20 fecal pellets a day. The pellets remain long after the mite is gone. Allergy problems are mainly caused by these fecal pellets. Dust mites like to live in warm, moist places (temperature 20 to 25C, humidity above 50%). Anyone with a dust mite allergy should try to avoid them. This may decrease allergy problems and the need for medicine.. ...

Background: Allergic sensitisation is a major risk factor for asthma in adults. In Sweden, pollens and furry animals are the main sensitisers, while mites play a minor role and often exists as co-sensitisation.. Aim: To study risk factors for mite sensitisation in Swedish adults.. Methods: Out of 18072 participants in the West Sweden Asthma Study, a random sample of 1472 aged 16-60 y were invited to skin prick testing (SPT) 2009-2012. SPTs covered 11 aeroallergens, including the mites D. pteronyssinus and D. farinae. Complete SPTs were performed in 788 subjects (58% women).. Results: The prevalence of any mite sensitisation was 12.6%, 11.3% to D. pteronyssinus and 9.6% to D. farinae. Physician-diagnosed asthma was seen in 12.1% and current wheeze in 23.6%. Sensitisation to pollens, animals and mites showed similar risk factor patterns, however mite sensitisation was also associated with work exposure to gas, dust and fumes (GDF), OR 2.0 (1.2-3.3) and low birth weight (,2500g, LBW) OR 1.9 (1.1- ...

Children aged one - two years with a family history of allergy, who had a positive skin prick test to house dust mites, had a higher risk of developing asthma later in life. Results showed 75 per cent of these children had asthma at aged 12 compared to 36 per cent of children without a positive skin prick test.. Lead author Dr Caroline Lodge from the University of Melbournes School of Population Health said the identification of house dust mites as a predictor for asthma in high risk children, is a significant step forward in identifying high risk groups on whom we can trial interventions.. Our findings provide researchers with a more targeted group of at risk children, for investigating strategies to prevent asthma later in life, she said.. House dust mite sensitivity amongst wheezy toddlers could be used as a clinical tool to assist parents in understanding the risk of asthma in their children..

Background There are many types of mites, but spider mites, eriophyid mites (many being gall-inducing mites) and predatory mites are the most important groups when plant care is involved. In this article, spider mites and their natural predators will mostly be addressed.
The scientists found that IgE-antibodies against three dust mite molecules (Der p 1, Der p 2 and Der p 23) appeared very early in the childrens blood, often before the onset of their disease. In some (but not all) children, this first step was followed by a cascade of events involving other mite molecules, through a phenomenon defined as molecular spreading. Children producing IgE to many molecules (polymolecular sensitization) had a higher risk of developing allergic rhinitis and asthma. Earlier onset of allergic sensitization, high exposure to house dust mite allergens, and having one or both parents affected by hay fever increased the risk of polymolecular sensitization. Interestingly, healthy pre-school children showing IgE antibodies to Der p 1 or Der p 23 developed more frequently asthma at school age. These and other molecules may be used for disease prevention in early life and to precisely tailor allergen immunotherapy in pediatric and adult patients ...

The flour mite, Acarus siro, a pest of stored grains, is one of many species of grain and flour mites. An older name for the species is Tyroglyphus farinae. The flour mite, which is pale greyish white in colour with pink legs, is the most common species of mite in foodstuffs. The males are from 0.33-0.43 millimetres (0.013-0.017 in) long and the female is from 0.36-0.66 mm (0.014-0.026 in) long. Flour mites contaminate grain and flour by allergens and they transfer pathogenic microorganisms. Foodstuffs acquire a sickly sweet smell and an unpalatable taste. When fed infested feeds, animals show reduced feed intake, diarrhea, inflammation of the small intestine, and impaired growth. Pigs have their live-weight gain, feed-to-gain ratio, and nitrogen retention markedly reduced by infested feeds. Flour mites are intentionally inoculated into Mimolette cheese to improve the flavor. When used for this purpose, they may be referred to as cheese mites. If a person is bitten from a flour mite they might ...

There are several species of mites called bird mites. These include the northern fowl mite (very common), the chicken mite, the American bird mite and many others. These mites are parasites on birds and are usually found on the birds or in their nests. Thus, under normal circumstances, bird mites go unnoticed. However, on occasion, bird mites wander away from the bird nests and are found indoors as accidental invaders.
Miniature inverted repeat transposable elements (MITEs) are abundant non-autonomous elements, playing important roles in shaping gene and genome evolution. Their characteristic structural features are suitable for automated identification by computational approaches, however, de novo MITE discovery at genomic levels is still resource expensive. Efficient and accurate computational tools are desirable. Existing algorithms process every member of a MITE family, therefore a major portion of the computing task is redundant. In this study, redundant computing steps were analyzed and a novel algorithm emphasizing on the reduction of such redundant computing was implemented in MITE Digger. It completed processing the whole rice genome sequence database in ~15 hours and produced 332 MITE candidates with low false positive (1.8%) and false negative (0.9%) rates. MITE Digger was also tested for genome wide MITE discovery with four other genomes. MITE Digger is efficient and accurate for genome wide retrieval of

Conservation and augmentative biological control strategies have been developed to take full advantage of the natural enemies that occur in Spanish citrus orchards. Among them, the predatory mites Euseius stipulatus, Neoseiulus californicus and Phytoseiulus persimilis play an important role in the biological control of tetranychid mites. However, these predatory mites are often affected by pesticides and information about the side-effects of these products against these beneficial arthropods is essential to guarantee their efficacy. The side-effects of some pesticides remain unknown and the primary aim of this study was to fill this gap. We have further used this information and that collected from other sources to compare the response of these three mite species to pesticides. Based on this information, E. stipulatus has the most tolerant species, followed by N. californicus and P. persimilis. Therefore, using E. stipulatus as an indicator species in citrus may have led to the paradox of ...

The clover mite, Bryobia praetiosa Koch, is a tiny relative of spiders and ticks. Thousands of clover mites can appear during spring or fall, and they are often found crawling around windows or other areas of a house. Clover mites are distinguished from other species of household-invading mites by their reddish-green color and long front legs (Figure 1). The front legs are as long as the body and almost twice the length of the other legs. These distinguishing features can be seen with the aid of a magnifying glass.. Vast numbers of clover mites can invade a house through cracks and tiny openings around windows and doors. Clover mites do not bite people or pets and do not damage the house or furniture, but they can stain light-colored walls, carpet, fabrics or papers when crushed.. Clover mites are plant feeders, and obtain nutrients by sucking plant juices. They usually prefer clovers and lawn grasses but will also feed on certain ornamental shrubs and trees. An abundance of soil nutrients ...

Tenuipalpidae comprises mites that transmit viruses to agriculturally important plants. Several tenuipalpid species present parthenogenesis, and in Brevipalpus yothersi, the endosymbiont Cardinium has been associated with female-only colonies. It is unclear what the bacterial composition of B. yothersi is, and how common Cardinium is in those microbiomes. We performed a comparative analysis of the bacteriomes in three populations of B. yothersi and three additional Tetranychoidea species using sequences from V4-fragment of 16S DNA. The bacteriomes were dominated by Bacteroidetes (especially Cardinium) and Proteobacteria, showing a remarkably low alpha diversity. Cardinium was present in about 22% of all sequences; however, it was not present in R. indica and T. evansi. In B. yothersi, the proportion of Cardinium was higher in adults than eggs, suggesting that proliferation of the bacteria could be the result of selective pressures from the host. This hypothesis was further supported because colonies of

The phytophagous two-spotted spider mite Tetranychus urticae Koch is a ubiquitous species, present worlwide on a large variety of plant families. Since T. urticae resistance spread rapidly, biological control tactics are crucial to manage spider mite populations. In this respect, plant-derived essential oil products are a good alternative as they are, in general, considered as minimum-risk pesticides. In that context, laboratory experiments were conducted to assess the toxicity of essential oil of Deverra scoparia endemic plant to North Africa on females of the two spotted spider mite T. urticae (Koch). Essential oil was distillated from fresh leaves from D. scoparia and was sprayed on groups of adults females. The susceptibility of these females to D. ...
Although spider mites have been reported as pests only since the late 19th Century (Titus, 1905, seen in Leigh, 1963), they appear to have been a pest problem whenever crops have been grown since earliest human cultures. The control of spider mites, however, was not a great problem to agriculturalists until two decades ago. The pest of orchards which is the so-called European red mite or fruit tree red spider mite, Panonychus Metatetranychus) ulmi Koch (= Paratetranychus pilosus C. & F.) had been noticed in various parts of the world, in particular in England and America, during the past fifty or sixty years. From about 1920 another mite of possibly even greater economic significance developed as a pest. This is the two-spotted spider mite or the glasshouse red spider mite or red carmine mite, Tetranychus urticae Koch (= T. Telarius L., T. Bimaculatus Harvey and T. Althaeae Hanstein). The damage caused by these pests, compared with that inflicted by other plant parasites, was of secondary ...
Two-spotted spider mites (Tetranychus urticae) are present in soybean crops every year, but they are not often a significant problem.
Overwintering mites may be reduced in numbers by the destruction of weeds such as pokeweed, Jerusalem oak, Jimson weed, wild blackberry, wild geranium and others. Insecticidal soaps and oils should be carefully considered when a pesticide is required. They are effective against mites and the least toxic to people, other non-target organisms and the environment. The effectiveness of laundry soaps, washing detergents, and vegetable oils is less consistent than with chemical pesticides. Although some growers have been quite pleased with the results of non-insecticidal quality soap and oil use, some have been disappointed. Also, plant varieties differ in their susceptibility to burning induced by soaps and oils. Environmental conditions, as well as micronutrients, fertilizers, and other additives may affect a tendency to burn foliage. At higher rates of application, (2%), burning and stunting are more likely (Capinera 1992). The twospotted spider mite develops a resistance to most acaricides after ...
ed in relation to the lack of reported spider mite outbreaks with fluvalinate. At the recommended field concentration (0.1 g a.i. 1⁻¹) for spider mites the toxicity of fluvalinate was minimal to two-spotted spider mite, Tetranychus urticae Koch, but was moderately toxic to European red mite, Panonychus ulmi Koch. Larvae of both species were the more susceptible stage and fluvalinate persisted long enough in laboratory experiments to control emerging larvae, even when applied to newly laid eggs. Differences between the toxicity of four fluvalinate formulations were only detected above field concentration. The emulsifiable concentrate formulation was the most toxic to two-spotted spider mite while the wettable powder formulation was most toxic to European red mite. The main response to fluvalinate was rapid dispersal from treated areas. Both spider mite species were able to accurately detect and avoid fluvalinate residues within and between leaves. There was a high survival rate for mites which ...
One of the keys to a successful scouting program is being ableto accurately identify the pests and diseases you come in contact with. Thefollowing is a review of the most prevalent greenhouse mites.. Two-spotted Spider Mite (Tetranychus urticae): The two-spotted spider mite is the most commonlyencountered greenhouse mite. Less than a millimeter in size, the two-spottedspider mite normally has two distinct spots on each side of the body beginningat the forward part of the body and ending just beyond half of the body length.The larval stage has six legs, whereas adults have eight. Spider mites canattack virtually every ornamental crop, including most species of foliageplants.. Indications of mite damage include a stippling or mottling,yellowing or bronzing of foliage causing early leaf drop. Where severe infestationsexist, plants may be covered with the characteristic webbing produced by thesemites, thus the term spider mite.. Spider mite infestations occur most often during hot, dryconditions and ...
Two-spotted spider mites damage crops by piercing leaves and feeding on the plant juices. Mites suck on the bottom sides of soybean leaves, removing plant moisture and nutrients, resulting in a yellow or whitish spotting on the top side of the leaf surface.
The two-spotted spider mite Tetranychus urticae usually lives in kin groups under common webs. Since only the first mating results in fertilisation in female T. urticae, adult males guard quiescent deutonymph females, those at the stage immediately before maturation, to ensure paternity. Therefore, the cost of precopulatory guarding time seems considerable for males. Moreover, the fitness indices of daughters from intra-population crosses were significantly lower than those of daughters from inter-population crosses, indicating that inbreeding depression exists in T. urticae. Therefore, we hypothesised that T. urticae males should be choosy in guarding familiar females to avoid inbreeding depression. Furthermore, webs should be a key element of the environment shared by familiar individuals. In this study, we demonstrated the inbreeding avoidance mechanism of T. urticae males in relation to webs produced by familiar females (known webs) or unfamiliar females (unknown webs). Regardless of ...
Spider mites injure plants by piercing cells and sucking out their contents, causing damage to leaves which then lose photosynthetic surface as feeding continues. Water loss can get out of control and both photosynthetic rate and leaf water status decline with increasing levels of spider mite injury.. Populations of mites are held in check by weather, host quality and natural predators. The last being far less effective during drought or very hot spells. Many of the extremely important predatory mite species responsible for keeping spider mite numbers below damaging levels do not function well in high temperatures. They will often leave the plant for leaf litter or other cooler and more protected areas, and become dormant.. In addition to spider mites being well-adapted and quick to develop pesticide resistance, often within a growing season, pesticides worsen the problem by destroying the predatory mite populations, thus eliminating the natural controls on the spider mite species and allowing ...

Phytophagous mites and thrips are important pests in many agricultural crops worldwide, representing a real threat to the agricultural production. Among the arthropods, they are phylogenetically distant, but both classes harbor species ranging from highly specialized to extremely polyphagous. They are specialized on feeding from epidermal or mesophyll tissues by means of stylets, even though their feeding modes have evolved independently. Both species are small and they often occupy similar niches in the plants boundary layer.More than 6,000 species of plant feeding mites are known worldwide, forming an integral and important part of the natural ecosystem. Among them, the two-spotted spider mite (Tetranychus urticae) is a cosmopolitan agricultural pest with an extensive host range feeding on cell contents of over 1,100 plant species, including more than 150 crops. Furthermore, many mites are also vectors of plant viruses responsible globally for spread virus pathogens of cereals and grasses, fruit
Scrub typhus, transmitted by larval chigger mites, is endemic in the Asia-Pacific region [20-23]. A total of 10,860 chigger mites collected from small mammals in South Korea were identified as only 8 species belonging to 4 genera [4], and a survey in Japan identified a total of 16,369 individual chigger mites belonging to only 10 species and 3 genera [3]. In contrast, the species diversity of chigger mites in China is much higher than the diversity cited in reports on chigger mites in other Asian countries, with , 400 chigger mite species that vary among the different provinces. For example, 18, 12, 15, and 41 chigger mite species were collected from small mammals (A. agrarius, R. norvegicus, M. musculus, C.triton, Rattus flavipectus, and Apodemus speciosus) from Liaoning, Jilin, Heilongjiang, and Hubei Provinces, respectively [24]. To date, at least 17 chigger mite species, belonging to 6 genera and 3 families have been identified from Shandong Province [25,26]. The present investigation ...
While pathogen-induced immunity is comparatively well characterized, far less is known about plant defense responses to arthropod herbivores. To date, most molecular-genetic studies of plant-arthropod interactions have focused on insects. However, plant-feeding (phytophagous) mites are also pests of diverse plants, and mites induce different patterns of damage to plant tissues than do well-studied insects (e.g., Lepidopteran larvae or aphids). The two-spotted spider mite, Tetranychus urticae, is among the most significant mite pests in agriculture. T. urticae is an extreme generalist that has been documented on a staggering number of plant hosts (more than 1,100), and is renowned for the rapid evolution of pesticide resistance. To understand reciprocal interactions between T. urticae and a plant host at the molecular level, we examined mite herbivory using Arabidopsis thaliana. Despite differences in feeding guilds, we found that transcriptional responses of A. thaliana to mite herbivory generally

Tetranychus urticae Koch is phytophagous in nature that can be the reason for major yield losses in many crops, fruits vegetables and ornamentals plants. Thus far, more than 3000 host species have been noted around the world in both outdoor crops and greenhouses. Our study explores the mechanisms of T. urticae dialing to provide a new understanding of the mechanism of controlling this pest including mentha plants (extracts and essential oils) which have an inhibitory effect on T. urticae. Even as mentha plants have been generally used to control T. urticae, in recent years, the interest in pesticides derived from plants has increased considerably as a result of environmental concerns and pest population resistance to conventional pesticides. Some pesticides can be easily produced but to study the mechanisms of their compounds against pests, are comparatively able against pests and with exceptions, their mammalian mortality and determination in the environment are undersized. Thus, the ...
An annual problem in the Papa Stronsay greenhouse is the Red Spider Mite (Tetranychus urticae). This mite is very small and reproduces rapidly.

It can be ordered online, and arrives in the post! ...
Bird Mites are parasites that can be seen on avian species or pet birds. Bird mites are oval in shape and less than 1mm long. They have 8 legs, hence are very mobile in nature. They spread from feathered creature to winged creature and rapidly turn into a major issue both for your pet bird and your home. Bird mites are extremely normal and can be effectively treated, however finding out the bird mite infestation is a challenging task. These creatures tend to multiply until they drop from the birds body and move from the confine into specific ranges of your home. The bird mites take a residence in the carpets, bed sheets and covers. Hold on, these mites just do not irritate the birds alone but, also bite human beings. If your home is affected by bird mite infestation, be prepared to be bitten by them if you do not treat the infestation at the earliest. ...

Recurring species interactions can cause species to adapt to each other. Specialization will increase the fitness of symbionts in the coevolved association but may reduce the flexibility of symbiont choice as it will often decrease fitness in interactions with other than the main symbiont species. We analyzed the fitness interactions between a complex of two cryptic mite species and their sympatric burying beetle hosts in a European population. Poecilochirus mites (Mesostigmata, Parasitidae) are phoretic on burying beetles and reproduce alongside beetles, while these care for their offspring at vertebrate carcasses. While Poecilochirus carabi is typically found on Nicrophorus vespilloides beetles, P. necrophori is associated with N. vespillo. It has long been known that the mites discriminate between the two beetle species, but the fitness consequences of this choice remained unknown. We experimentally associated both mite species with both beetle species and found that mite fitness suffered ...
The two common guinea pig fur mites are Trixacarus caviae (sarcoptic mange mite) and Chirodiscoides caviae. Chirodiscoides caviae mites may cause mild to no clinical signs at all. Trixacarus caviae mites can cause extreme clinical signs because they cause extreme itchiness. Affected skin will get thick, yellowish, and crusty, with hair loss and secondary bacterial skin infection. These mites cause such itchiness that your guinea pig may even go into seizures and die. Your veterinarian will treat the affected animal with topical or injectable anti-parasitic medications, and since mites live in the environment, the environment must be treated, as well. Trixacarus caviae mites are contagious to people.
Miniature inverted-repeat transposable elements (MITEs) are widespread in plants and animals. Although silkworm (Bombyx mori) has a large amount of and a variety of transposable elements, the genome-wide information of the silkworm MITEs is unknown. We used structure-based and homology approaches to search for MITEs in the silkworm genome. We identified 17 MITE families with a total of 5785 members, accounting for ~0.4% of the genome. 7 of 17 MITE families are completely novel based on the nucleotide composition of target site duplication (TSD) and/or terminal inverted repeats (TIR). Silkworm MITEs were widely and nonrandom distributed in the genome. One family named BmMITE-2 might experience a recent burst expansion. Network and diversity analyses for each family revealed different diversification patterns of the silkworm MITEs, reflecting the signatures of genome-shocks that silkworm experienced. Most silkworm MITEs preferentially inserted into or near genes and BmMITE-11 that encodes a germline
Mites are the third member of the team that is out to get your garden (fungus, insects, mites). These critters are a difficult problem once they are established, but there are steps that can be taken to ensure they don't get comfortable in the rose garden. The mite that we deal with most often is the Two Spotted Spider Mite. Spider Mites are in the arachnid family and are almost invisible to the naked eye. They can easily be seen with a magnifying glass and unfortunately the results of their feeding on your roses can be seen easily with the naked eye. Spider Mite Symptoms Generally leaves will lose their brilliant green color and become faded and brown. You can often see their webbing on the underside of the leaves. The underside of the leaves will also look dusty because of the dirt and debris that get caught in their webs. What Can I Do?

Population density and phenology of Tetranychus urticae (Acari: Tetranychidae) in hop is linked to the timing of sulfur applications.
Two-spotted mite, Tetranychus urticae (see Sheet 300), is the most common spider mite in plantscapes; it feeds on a wide range of plants. Citrus red mite, Panonychus citri, is less common, has a smaller host range, but can be damaging when it occurs; in addition to citrus, this mite attacks palms, figs, ginger and bananas. In plantscapes, spider mites are often a problem on foliage in the warmest and driest areas, such as in summer at the top of tall plants nearest the glass. Their feeding causes white stippling on the leaves and, in severe infestations, the leaves turn brown and collapse. ...
In December 1995 we took dust samples from nine pairs of pillows and analysed them for Der p I. Each pair consisted of one feather filled pillow and one filled with polyester fibre; these had been used together on the same adult bed for more than six months to ensure that the environmental exposures of the pillows in each pair were similar. The pillow fillings were encased in closely woven cotton fabric. Two of the subjects in our study slept with the polyester filled pillow on top, four with the feather filled pillow on top, and three had no preference. We took dust samples with a portable Hitachi CV-2500 vacuum cleaner with a sock attachment, vacuuming each pillow for three minutes on each side, a total of six minutes per pillow. We sieved the dust collected to remove fluff and large particles and weighed the resulting fine dust. We then analysed this dust for Der p I content using monoclonal antibody enzyme linked immunosorbent assay (ELISA).2 The between batch coefficient of variation of the ...

In southwestern Taiwan, the percentage of sensitization to HDM has not been estimated. We retrospectively reviewed the medical records of asthmatic patients treated at the Chiayi branch of Chang Gung Memorial Hospital to investigate the percentage and associations with demographic characteristics. Methods: We analyzed the data of 194 asthmatic patients diagnosed between January 2003 and July 2005. Sensitization to indoor allergens was identified by serum specific immunoglobulin E (IgE) of ImmunoCAP. Demographic ...
Almost all teens get acne during teenage years. According to some studies, 90% of teenage acne is caused by Demodex mites (so called face mites) and that only 10% is caused by bacteria. It can be explained by increased production of sebum by sebaceous glands during teenage years (between 13 and 19) when sebum clogs pores. During this period of life teenagers experience dramatic hormonal fluctuations which make face skin ideal breeding ground for Demodex mites and teenage acne.. Demodex mites are tiny microbial insects that live in the skin (in the hair follicles) of nearly every person. Demodex mites can live on any body parts wherever there are hair roots and sebaceous glands. They are most prevalent in the facial area (nose, forehead, chin and cheeks) - facial area has the most favorable living and breeding conditions and provides the optimum temperature for mites to thrive. Often Demodex mites become more aggressive when the immune system is weakened (stress, diseases, infections). Usually ...
Prevention of ear mites is an important process to avoid the hassle and pain of a mite infestation. Maintaining healthy dog ear hygiene is one way to prevent the spread of ear mites. Flea treatments containing ivermectin, fipronil or selamectin also help to prevent parasites like ear mites. All animals in your home should be treated with these medications to prevent the spread of parasites should one animal become infected. If your dog does become infested your veterinarian will wash the ears out and prescribe a medication such as dog ear drops or an ear wash with insecticide. These medications clean out the ear canal and kill any ear mites living off ear wax and debris. Your dogs bedding should also be washed to eliminate any remaining mites, though these parasites do not live long without a host. ...
Stippling consists of small light-colored spots in the leaves. These are often grouped in small patches when spider mite populations are low and can cover large portions of the plant when infestations are high. Spider mites can produce silk, which gives rise to their name spider mites. This webbing isnt noticeable when populations are low, but as mites increase in number, webbing may be seen between leaf petioles and stems or leaflets. Mites feeding on fruit with their piercing sucking mouthparts cause similar stippling, which is sometimes referred to as gold flecking on tomatoes.. ...

A dust mite allergy is in fact a reaction to proteins in the excretion of the dust mites. Yes, thats right, youre allergic to dust mite poo.. All homes in the UK have dust mites, but due to their tiny size (around 0.25-0.3mm) and translucent bodies they are almost invisible to the naked eye (dont worry - unless you have a dust mite allergy, they are harmless).. When the allergenic proteins are breathed in or make contact with the skin of an allergic person, their body reacts with symptoms - wheezing, sneezing, runny nose and soreness and redness of the skin and eyes.. Dust mites thrive in warm humid environments, our beds being one of their favourite spots. We spend about a third of our day in bed, shedding skin cells and creating moisture with our breath and bodies which the microscopic mites need to live on.. ...

The effects of parasitism on host survival and reproduction can be highly complex depending on the type of parasites, host sex and life-history characteristics, and ecological conditions. In this study, we tested sex-biased parasitism from Trombiculid mites (Acarina: Trombiculidae) and their sex-specific effects on host reproduction and survival, in a natural population of the Taiwan field mouse (Apodemus semotus). We performed surveys of A. semotus and their Trombiculid mites between April 2010 and August 2011 and again between June and September 2012 in a subtropical evergreen forest in Taiwan. Contrary to the commonly reported male-biased parasitism in mammals, we did not find sex-biased parasitism in A. semotus. We found that mite abundance was negatively associated with A. semotus reproduction and survival in both males and females. The mite abundance and rodent reproduction fluctuated seasonally, and the peak reproductive season coincided with the time period of relatively low mite abundance.
That exposure to high levels of house dust mite allergen was associated with deteriorating BHR was not an unexpected finding. House dust mite allergens include a number of proteases and trypsins that may disrupt cell membranes and have direct pro-inflammatory actions, and they also mediate airway inflammation through IgE activation [21]. They may therefore contribute to the persistence of airway inflammation over time, and perhaps a consequent increase in bronchial hyperresponsiveness.. Early-life exposure to dogs is associated with a reduced likelihood of developing asthma in children,[22] but there are no data for adults with asthma. It is interesting therefore that we have found an association between exposure to high levels of dog allergen and improvement of BHR. We considered the possibility that subjects may have gotten rid of their dog between visits, but even after controlling for this, we discovered that the association remained the same. It is also possible that dog ownership per se ...
The creatures commonly called dust mites are in fact two different species of arachnids: Dermatophagoides pteronyssus and Dermatophagoides farinae. These insect are about 0,3 mm long and they are related to spiders. The number of dust mites increases at the end of spring, in the summer and at the beginning of the fall, because the air inside homes becomes more moist when the heating system is off. During the winter the air becomes drier as soon as the homes begin being heated, and these circumstances are not favourable for dust mites. Dust mites feed on dead human skin cells; therefore they occur in large numbers in areas where dead skin cells are abundant: bed sheets, pillows, furniture, throws, carpets and plush toys. The feces of dust mites break into microscopical particles, they become airborne, and cause allergic reactions if they are inhaled or reach the skin. Among household allergens, dust mite feces cause respiratory allergies the most often.. Our respiratory system is the part of the ...
Under attack by herbivores, plants produce a blend of herbivore-induced plant volatiles (HIPV) that help natural enemies of herbivores locating their prey, thereby helping plants to reduce damage from herbivory. The amount of HIPV emitted by plants increases with herbivore density and is positively correlated with the intensity of the olfactory response of natural enemies. In this study, we determined the effects of density or within-plant distribution of the herbivorous mite Mononychellus tanajoa on movement of the predatory mite Typhlodromalus aripo out of apices of cassava plants. Proportions of T. aripo that migrated out of apex, and distances traveled were significantly higher when M. tanajoa was further away from the apex-i.e. on middle or bottom leaves of cassava plants-than when present on top leaves, or absent from the plant. This supports previous field observations that T. aripo is not a sit-and-wait predator but uses HIPV to search and locate its prey within cassava plant ...

Human beings are the one and only host of this ubiquitous mite (a). In fact, these two mites are considered to be the most common ectoparasite of humans (d). Women tend to be the main beneficiary of these minute bugs, with a male:female ratio of 2:5 (c). Sorry, ladies. The rate of infestation seems to be correlated with age, with 84% of people at age 60 harboring mites and increasing to 100% in those 70 years and older (e). Whether those that are immunocompromised are more susceptible to higher infestation rates is unknown, though some studies indicate that AIDs and leukemia patients may be more prone to greater than average numbers (c).. The mites may be found in the scalp, face and upper chest area, with D. folliculorum exhibiting a predilection for the hair follicles and D. brevis for the sebaceous ducts and meibomian glands at the rim of the eyelids (the sebaceous ducts transfer the waxy sebum that lubricates the skin and hair from the sebum glands; the meibonmian glands are a special type ...
