tetranychus urticae host plants

Antixenosis is not a factor in HPR because resistant and susceptible cultivars were equally attractive ( Gould, 1979 ). Environmental effects, such as amount of water or natural enemies, must be considered in a resistance management strategy because certain regions may experience climatic conditions for which HPR expression is compromised. … Although not common, TSSM feeding damage on tomato flowers causes a browning and withering of the petals. Mites are most easily detected along the south side of the greenhouse and at the end of beds where temperatures are high. Developmental times for each life stage have been determined for constant temperatures (Table 2). - Host plants: this mite is extremely polyphagous attacking almost 200 different hosts: wild plants, ornamentals, vegetable plants, fruit species. The flecks are only in the epidermal layer of the fruit and do not penetrate beyond this (Brust, 2014). Tetranychus urticae (common names include red spider mite and two-spotted spider mite) is a species of plant-feeding mite generally considered to be a pest. T. urticae is among the most polyphagous herbivores known: It can feed on over 1,100 different plants in more than 140 different plant families that produce a broad spectrum of chemical defenses ( 29 ). Flexner et al. Treating boxes of chrysanthemum cuttings with both T. urticae and the predator Phytoseiulus persimilis Athias-Henriot at the rate of one per plant and one per 50 plants gave excellent control (Scopes & Biggerstaff, 1973). T. urticae has a very wide host range. Fry (1992) found that adaptation to tomato (Solanum lycopersicum) did not significantly increase or decrease ability to survive on tobacco and cucumber. However, lines of mites that were originally adapted to cucumber and tomato gradually lost the ability to utilize these hosts after acclimation to an attractive host, such as lima bean (Gould, 1979; Fry, 1990; Agrawal, 2000). Abstract: Tetranychus urticae is a serious pest of several crops worldwide. It performs differentially on diverse host‐plant species. A review of biological control of T. urticae in greenhouses is available (Osborne et al., 1985). It developed fastest at 35 deg C (6.50 d) and 30 deg C (6.93 d), whereas at 15 deg C it took 16.23 d. The higher the temperature, the faster the development of the mite. In determining the adaptation to HPR in the presence of natural enemies, one must ascertain whether those natural enemies will increase or decrease the fitness differential (Gould et al., 1991). The effectiveness of natural enemies of arthropods can be directly influenced by morpho- logical characteristics of the host plant or secondary plant compounds (Vinson, 1976). [2], The mite's natural predator, Phytoseiulus persimilis, commonly used as a biological control method, is one of many predatory mites which prey mainly or exclusively on spider mites. David W. Onstad, in Insect Resistance Management (Second Edition), 2014. Yellowing and speckling are the most common early plant responses to feeding, though reddening may also occur. Resistance to HPR cucumbers promoted resistance by T. urticae to other plant or insecticidal compounds. By continuing you agree to the use of cookies. Finally, one important aspect of IRM is the initial proportion of resistance alleles in a population. [6], The egg of T. urticae is translucent and pearl-like. The pest feeds mostly on the underside of the leaf, and the eggs are laid there, so it is crucial that miticide coverage be adequate there. Tetranychus urticae Koch (Acari: Tetranychidae), the two-spotted spider mite (TSSM), is one of the most polyphagous herbivores that feeds on over 1100 plant species, including more than 150 crops species (Jeppson et al., 1975; Migeon and Dorkeld, 2006–2016). T. urticae is also implicated in the transmission of several viruses that include potato virus Y, tobacco mosaic virus, and tobacco ringspot virus. Abstract Systematic surveys in the field and laboratory were carried out to explore the dispersion pattern of T. urticae and its selection of host plants in the irrigation region and a reclamation region in Ningxia, China. Fry (1990) reported no difference in survival or fecundity on lima bean, a highly preferred host, when comparing bean- and tomato-adapted mites. In a study by Meck (2010) on tomatoes in North Carolina (United States), it was found that economic thresholds were very low at 1–2 mites/tomato leaflet. The reverse effect, however, was not observed; mites resistant to several insecticides did not have higher survivorship on resistant cucumber varieties than the susceptible mites did. This releases cellular content of the epidermal cells which the mite sucks up using its rostrum. To elucidate the relationship between host plant adaptation and pesticide resistance in a systematic way, the two-spotted spider mite, Tetranychus urticae, is an excellent choice. Although the indi… Egg laying is rapid at first and then declines slowly. Flexner et al. [2] It is the most prevalent pest of Withania somnifera in India. In spider mites, past genetic and ecological studies have comprehensively suggested that the local concentration of resistance genes (increasing gene frequency in breeding patches) resulting from genetic diversity within habitats based on their biological traits and selection by acaricides, and gene flow from selection sites to surroundings (local and/or regional spread of resistance) are the processes of acaricide-resistance evolution (Osakabe et al., 2009). In contrast, the resistant mites destroyed HPR seedlings regardless of water stress, but did have lower survivorship on stressed plants (Gould, 1978b). [1], T. urticae is extremely small, barely visible with the naked eye as reddish or greenish spots on leaves and stems; the adult females measure about 0.4 mm long. After several days of heavy mite feeding, necrotic spots begin to develop on leaf tissue and leaves will turn yellow or gray and collapse. Figure 5.2. Its short life cycle and high reproductive potential predispose this mite to evolving resistance to many chemical control methods, so some growers may opt to use HPR plants. It has been spread throughout the temperate regions of the northern hemisphere by wind and throughout the world via the transport of plants by man. Front. urticae. D.W. Onstad, Lisa Knolhoff, in Insect Resistance Management (Second Edition), 2014. Injection of plant growth regulators or interference with growth regulators during feeding is also reported. Jayasinghe and Mallik (2010) in Thihagoda, Sri Lanka found that the middle developmental stage of tomato was the most critical period for mite damage and accounted for more than 50% of the total yield loss compared with early or late infestations. Gould (1978b) found that mites that were not adapted to HPR cucumbers still destroyed susceptible varieties, but they did no noticeable damage to water-stressed seedlings. We thus compared on a same host the performance of replicated populations from an ancestral one reared for hundreds of generations on cucumber plants that were shifted to either tomato or cucumber plants. These mites do not feed or reproduce until favourable conditions resume. put it, plants may “cry for help” when attacked by spider mites and predatory mites come to the rescue. When a spider mite infestation is discovered, release of 10 predators per 10 plants within infested areas is recommended (Wardlow, 1986). Mite products such as webbing, eggs, cast skins, and fecal material also detract the cosmetic quality of plants. If a more favorable alternative host is present and the pest can access it, this should weaken selection for resistant pests (Cantelo and Sanford, 1984). This spider mite is extremely polyphagous; it can feed on hundreds of plants, including most vegetables and food crops – such as peppers, tomatoes, potatoes, pepinos, beans, maize, and strawberries, and ornamental plants such as roses. Yield loss is not only due to a reduction in tonnage of fruit, but also quality and size and therefore marketable yield (Oldfield, 1970; Metcalf and Metcalf, 1993; Meck, 2010). The two‐spotted spider mite, Tetranychus urticae Koch, occurs in two colour forms in greenhouses in the Netherlands: a red form on tomato and a green form on cucumber. After a waiting period of up to 3 days, the adult female begins to lay eggs. Tetranychus urticae is the most common pest of orchards and a frequent target of pesticide applications. In: Bruin J., van der Geest L.P.S., Sabelis M.W. The increasing availability of whole genome sequences and EST databases strongly stimulate mite resistance research. Certain morphological features may have a larger effect on the evolution of resistance. One host of T. urticae is cucumber (Cucumis sativus). Antixenosis as an HPR mechanism is likely to affect the evolution of resistance. They can easily be distributed throughout a rose planting during one flower harvest. Leaf transpiration is accelerated, and affected leaves may dry and drop from the plant. As feeding damage progresses a stippled appearance of the foliage is evident. Table 2. The protonymph is transformed into the slightly larger deutonymph and, although this stage has similar coloration, males and females can usually be distinguished. It lays its eggs on the leaves, and it poses a threat to host plants by sucking cell contents from the leaves cell by cell, leaving tiny pale spots or scars where the green epidermalcells have been destroyed. Mites reared on detached rose leaves under two alternating night/ day temperature regimes, 10/20 °C and 25/35 °C, took 8.3 and 28.2 days, respectively, to complete their life cycle. (1995) concluded that the field durability of the acaricides was not extended by rotations or half-rate combinations compared with consecutive uses. These flecks have been determined to be calcium oxalate crystals (Den Outer and Van Veenendaal, 1988). [4][5], T. urticae reproduces through arrhenotoky, a form of parthenogenesis in which unfertilized eggs develop into males. From apples to zucchini – no matter what types of plants you grow – it's likely something spider mites will attack. Temperature plays a key role in the time needed for development of Tetranychus urticae. It is well recognized that the quality of host plants affects the development and survival of twospotted spider mite Tetranychus urticae Koch. MATERIAL AND METHODS. This feeding damage is rough to touch and has small depressed areas where the mites have removed chlorophyll and the cells have collapsed. Therefore, this EIL does not lend itself to commercial use. T. urticae is generally known to be active on the underside of leaves, except under high population density. Before the 1940s, spider mites were infrequently considered to be serious pests, but since then they have assumed major pest status in some crops. However, these studies have not been satisfactory for understanding the scope of acaricide resistance in T. urticae. So far, resistance has been reported in several countries for compounds such as organophosphates (OPs) (Anazawa et al., 2003; Sato et al., 1994), dicofol (Fergusson-Kolmes et al., 1991), organotins (Edge and James, 1986); hexythiazox (Herron and Rophail, 1993), clofentezine (Herron et al., 1993), fenpyroximate (Sato et al., 2004) and abamectin (Beers et al., 1998). While this EIL is a good place to start in understanding the relationship between mite numbers, feeding duration, and yield reduction, it is not practical at this time because it is impossible to know when and how many mites were initially there on a tomato plant and how long they had been feeding. Archives of Phytopathology and Plant Protection: Vol. plants. This mite has a long history of evolving resistance to acaricides. Antixenosis is not a factor in HPR because resistant and susceptible cultivars were equally attractive (Gould, 1979). could be important for IRM. The two-spotted spider mite Tetranychus urticae is an important pest with an exceptionally broad host plant range. ScienceDirect ® is a registered trademark of Elsevier B.V.

Once mites were adapted to an HPR cultivar of cucumber, they were predisposed to utilize tobacco (Nicotiana tabacum) and potato (Solanum tuberosum) as hosts (Gould, 1979), which are both taxonomically and chemically unrelated to cucumbers. Gould (1978a) found that adaptation to HPR cultivars of cucumber expressing antibiosis could occur in as little as nine generations. T. urticae was originally native only to Eurasia, but has acquired a cosmopolitan distribution. This review is an update of the current state of the art in the molecular interactions between the generalist pest T. urticae and its host plants. The gnathosoma includes only the mouthparts. The life cycle of the two-spotted spider mite consists of five stages of development: the egg, larva, protonymph, deutonymph and adult. The mite does not actually inject the virus into the plant, instead excretes the virus onto the leaf surface and allows entry of the virus into the plant through feeding damage (Oldfield, 1970; Jeppson et al., 1975). S.A. Tjosvold, J.F. Factors affecting economic decisions by the producer cannot be ignored. Both T. urticae and T. cinnabarinus have been found to cause an unusual hyper-necrotic response in tomato that involves premature chlorosis of infested leaflets that consequently wilt and die (Foster and Barker, 1978; Szwejda, 1993). As Dicke et al. Control is more difficult than for other pests because of the large populations involved and also because of their ability to develop resistance to pesticides. The adults are typically pale green for most of the year, but later generations are red; mated females survive the winter in diapause. Rates of resistance to structurally diverse pesticides in T. urticae are unprecedented, with some field strains resistant to nearly all available compounds (Van Leeuwen et al., 2010). Spider mites damage their host plants while feeding, using More recently, the recommendation for use of P. persimilis is to release predators weekly throughout the life of a chrysanthemum crop at the rate of 10 predators for every 200 plants (Wardlow, 1986). (1989) determined that fitness costs and immigration of susceptibles could cause reversion of acaricide resistance when selection pressure is relaxed. John L. Capinera, in Handbook of Vegetable Pests (Second Edition), 2020. The twospotted spider mite, Tetranychus urticaeKoch, has been controversial in its taxonomic placement. Its phytophagous nature, high reproductive potential and short life cycle facilitate rapid resistance development to many acaricides often after a few applications (Cranham and Helle, 1985; Devine et al., 2001; Keena and Granett, 1990; Stumpf and Nauen, 2001). They studied the dynamics of resistance in T. urticae in pear orchards for seven years. The development time varies with temperature, humidity, host plant, leaf age and other factors, with temperature the most important factor. The type of host plants varied among mite species; for example, T. okinawanus was frequently found on indigenous plants inhabiting the seashore and invasive weeds, T. piercei and T. parakanzawai on inland indigenous plants, T. urticae (green form) on invasive weeds, and T. neocaledonicus on introduced trees. The two-spotted spider mite Tetranychus urticae is an important pest with an exceptionally broad host plant range. It is also a problem on protected and unprotected strawberries. This mite is polyphagous and attacks the broad range of crops, including soybean, Alternate, consecutive uses may give greater than 33% longer control compared with control for other programs. The most common spider mite, the twospotted spider mite (Tetranychus urticae), is a general feeder that attacks a wide variety of fruits, vegetables, and ornamentals. Evolutionary adaptation to host plants in a laboratory population of the phytophagous mite Tetranychus urticae Koch James D. Fry* Department of Biology, University of Michigan, Ann Arbor, MI 48109-1048, USA Summary. of different host plants on biology of Tetranychus urticae under controlled temperature (28.5±2 °C) and relative humidity (76±5%). Feeding principally on the underside of the leaf, mites leave pinpoint chlorotic spots that turn the leaf bronze when the population is high. Flexner et al. About 60 synonyms included under this species have compounded the controversy. Gerald E. Brust, Tetsuo Gotoh, in Sustainable Management of Arthropod Pests of Tomato, 2018. Tetranychus urticae spend most of its life cycle on plant, especially on leaves, and it causes serious damage. The fact that these mites are polyphagous has many implications for devising a resistance management strategy with HPR hosts. It includes many crops grown in glasshouses such as tomatoes, cucumbers and peppers and flowers such as chrysanthemums and orchids. These environmental factors can convert plants which might be only poor hosts into very good hosts, resulting in mite population increase and crop damage. The evolutionary status of these strains was analysed by studying genetic differentiation, host plant preference, and mate choice. Mites will feed directly on the tomato fruit, usually at the stem-end around the cap area (Meck et al., 2009). TSSM is an extreme generalist with an outstanding ability to rapidly develop resistance to xenobiotic compounds. The egg hatches into a clear six-legged larva with noticeable crimson-coloured eye spots. 52, No. The idiosoma is the remainder of the body and parallels the head, thorax and abdomen of insects. Reversion of resistance could indicate a possible fitness cost associated with it. The two-spotted spider mite (Tetranychus urticae Koch) can be a problem on chrysanthemums, with some cultivars more sensitive than others. Twospotted spider mites have longer stylets (100–150microns long), about 1.5–2 times the diameter of a human hair, so they can access the parenchyma cells just below the epidermal cells. Therefore, an IPM-like approach to resistance management could be beneficial. The period during which eggs are deposited can last from 10 days (34 °C) to 40 days (15 °C). When this flecking is severe it can reduce the market value of the fruits. Apparently, mite problems are induced by crop management practices, particularly the use of broad-spectrum insecticides (see section on “insecticides”). T. urticae may also important as allergen in asth- The chemicals released seem to … Acaricide resistance mechanisms in the two-spotted spider mite Tetranychus urticae and other important Acari: A review. This range is so large because mite infestations can be severe in some areas of a field and almost nonexistent in others. Here, we performed experimental evolution with the polyphagous spider mite Tetranychus urticae to detect how mites can exploit host plants. Dispersion of two-spotted spider mite, Tetranychus urticae Koch, and its selection of host plants on farmland in Ningxia.

[1] It hatches into a larva, and two nymph stages follow: a protonymph, and then a deutonymph, which may display quiescent stages. The two-spotted spider mite, Tetranychus urticae Koch has become a model species for phytophagous mites due to the development of a great number of genetic tools and a high-quality genome sequence. Biological responses of the two-spotted spider mite, Tetranychus urticae to different host plant. According to the Arthropod Pesticide Resistance Database, two-spotted spider mites have recorded an astonishing 389 cases of resistance, the highest amongst all arthropods (including both insects and mites). The lower threshold for development is about 12 °C and the upper limit for development is about 40 °C. With respect to resistance management, Gould (1978a) highlighted the need to test multiple populations of the insect target and to look at population size, mobility, and whether there is mono- or polygenic inheritance of resistance.
