tetranychus urticae host plants

Keywords: Tetranychus urticae, two-spotted spider mite, plant-pest interaction, stylet, chlorosis, microscopy, bean, Arabidopsis. Before the 1940s, spider mites were infrequently considered to be serious pests, but since then they have assumed major pest status in some crops. One thing to consider is whether the pest will feed upon resistant cultivars or merely be repelled; resistance is thought to evolve more slowly if the pest simply avoids the resistant cultivar over the susceptible one (Cantelo and Sanford, 1984). 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. Another fruit problem caused by TSSM is gold flecking, which appears as yellow or gold spots scattered over the surface of the fruit as it ripens. [6], The egg of T. urticae is translucent and pearl-like. Flexner et al. Damage can be seen as chlorosis of the leaves where the mites have been feeding. S. Mohankumar, ... R. Samiyappan, in Integrated Pest Management, 2014. 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. 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). Crop losses can occur when about 30% of the tomato leaf surface is damaged by spider mite feeding. D.W. Onstad, Lisa Knolhoff, in Insect Resistance Management (Second Edition), 2014. (1989) determined that fitness costs and immigration of susceptibles could cause reversion of acaricide resistance when selection pressure is relaxed. Special spray nozzles have been designed for mite control. [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. Dispersion of two-spotted spider mite, Tetranychus urticae Koch, and its selection of host plants on farmland in Ningxia. The evolutionary status of these strains was analysed by studying genetic differentiation, host plant preference, and mate choice. David W. Onstad, in Insect Resistance Management (Second Edition), 2014. Temperature plays a key role in the time needed for development of Tetranychus urticae. The life cycle usually ranges from 10 days to 2 weeks. The fact that these mites are polyphagous has many implications for devising a resistance management strategy with HPR hosts. HPR of tomatoes and broccoli seems to be both behavioral and toxicological, in that mites tended to disperse from these plants and had high mortality on them (Fry, 1989). [7] Inbred progeny mature more slowly than outbred progeny, and inbred female progeny have lower reproductive output. After hatching from the egg, the first immature stage (larva) has three pair of l… These flecks have been determined to be calcium oxalate crystals (Den Outer and Van Veenendaal, 1988). Mites can flourish even in winter where the climate is warm or in glasshouse conditions where host plants are available. HPR may take place as an antixenotic mechanism because of the morphological features of these hosts: trichomes and wax, respectively (Fry, 1988, 1989). The increasing availability of whole genome sequences and EST databases strongly stimulate mite resistance research. Phytophagous mites infest most host plants as vegetable, field crops, and ornamental plants. The two-spotted spider mite Tetranychus urticae is an important pest with an exceptionally broad host plant range. After several days of heavy mite feeding, necrotic spots begin to develop on leaf tissue and leaves will turn yellow or gray and collapse. 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. This mite has a long history of evolving resistance to acaricides. In addition, Gould et al. Disruption of photosynthesis results in stunting of plant growth and reduced-fruit yields. Mite products such as webbing, eggs, cast skins, and fecal material also detract the cosmetic quality of plants. 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. Thirteen newly emerged females were transferred with adult males in couples from a culture maintained at Sakha laboratory by camel brush on 13 discs of each of sweet potato, mulberry, and castor While adaptation to cucumbers seems to confer advantages with respect to other hosts or chemical controls, there may be either no effect or even a cost associated with adaptation to another host. The idiosoma is the remainder of the body and parallels the head, thorax and abdomen of insects. Resistance alleles are usually assumed to be rare because they seem to have some cost associated with them. populations can outbreak to high densities and cause serious damage to host plants. Much research has been conducted on the spider mite Tetranychus urticae, the predatory mite Phytoseiulus persimilis, and the host plants. 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. As Dicke et al. This range is so large because mite infestations can be severe in some areas of a field and almost nonexistent in others. One host of T. urticae is cucumber (Cucumis sativus). T. urticae has a very wide host range. By continuing you agree to the use of cookies. Fry (1992) found that adaptation to tomato (Solanum lycopersicum) did not significantly increase or decrease ability to survive on tobacco and cucumber. 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. From apples to zucchini – no matter what types of plants you grow – it's likely something spider mites will attack. 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). [4][5], T. urticae reproduces through arrhenotoky, a form of parthenogenesis in which unfertilized eggs develop into males. It includes many crops grown in glasshouses such as tomatoes, cucumbers and peppers and flowers such as chrysanthemums and orchids. 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). Twospotted spider mite can feed on 18–22 cells per minute, resulting in many dead cells, and often a speckled appearance. 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. Figure 5.2. It is also a problem on protected and unprotected strawberries. 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. Front. These mites do not feed or reproduce until favourable conditions resume. Studies of pesticide resistance in T. urticae have focused largely on target-site mutations and on classical detoxifying enzyme systems, such as P450 monooxygenases (P450s), carboxyl/cholinesterases and glutathione-S-transferases (Ghadamyari and Sendi, 2009). In: Bruin J., van der Geest L.P.S., Sabelis M.W. 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. KEY WORDS: host plant, legumes, life table, Tetranychus urticae The two-spotted spider mite, Tetranychus urticae Koch (Acari, Tetranychidae) is one of the most serious agricultural pests in the world. of different host plants on biology of Tetranychus urticae under controlled temperature (28.5±2 °C) and relative humidity (76±5%).

Karlik, in Encyclopedia of Rose Science, 2003. 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. Gold fleck is thought to be a response to certain stresses the plant encounters during the season, such as high temperatures and humidity or TSSM or thrips feeding (De kreij et al., 1992; Ghidiu et al., 2006; Brust, 2014), or too high a level of calcium in the fruit as it is ripening (Den Outer and Van Veenendaal, 1988). By studying colonization suc- cess on various marginal host plants, Gould When this flecking is severe it can reduce the market value of the fruits. It is well recognized that the quality of host plants affects the development and survival of twospotted spider mite Tetranychus urticae Koch. Plants Therefore, an IPM-like approach to resistance management could be beneficial. Leaf transpiration is accelerated, and affected leaves may dry and drop from the plant. The development time varies with temperature, humidity, host plant, leaf age and other factors, with temperature the most important factor.

(1995) concluded that the field durability of the acaricides was not extended by rotations or half-rate combinations compared with consecutive uses.

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 feeding damage is rough to touch and has small depressed areas where the mites have removed chlorophyll and the cells have collapsed. Flexner et al. urticae. - Host plants: this mite is extremely polyphagous attacking almost 200 different hosts: wild plants, ornamentals, vegetable plants, fruit species. Yellowing and speckling are the most common early plant responses to feeding, though reddening may also occur. Navajas M. (1999) Host plant associations in the spider mite Tetranychus urticae (Acari: Tetranychidae): insights from molecular phylogeography. The adults are typically pale green for most of the year, but later generations are red; mated females survive the winter in diapause. It is particularly damaging to vine, bean, cucumber, hop, cotton, clover, sunflower, fruit trees. In contrast, the resistant mites destroyed HPR seedlings regardless of water stress, but did have lower survivorship on stressed plants (Gould, 1978b). Fry (1988) found large differences in survivorship on tomato in populations of mites. [3] 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 epidermal cells have been destroyed. Dominic J. Durkin, in Introduction to Floriculture (Second Edition), 1992. 52, No. [1], Inbreeding is detrimental for fitness in T. 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). The genetic variability with respect to resistance seems to be common in many populations. 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). However, these studies have not been satisfactory for understanding the scope of acaricide resistance in T. urticae. 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. The chemicals released seem to … Generally, adaptation to host plant resistance occurs more slowly with a combination of low HPR and natural enemies than a high level of HPR alone (Gould et al., 1991). Also the insensitivity of AChE to demeton-S-methyl, ethyl paraoxon, chlorpyrifos oxon and carbofuran was identified in a German laboratory strain of T. urticae and a field collected strain from Florida (Stumpf et al., 2001). plants. T. urticae is also implicated in the transmission of several viruses that include potato virus Y, tobacco mosaic virus, and tobacco ringspot virus. (1982) found that mites adapted to HPR cucumber had significantly higher survivorship when exposed to three organophosphate insecticides. 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. The two-spotted spider mite (Tetranychus urticae) remains the most important pest on greenhouse roses. [2] Although the individual lesions are very small, attack by hundreds or thousands of spider mites can cause thousands of lesions, thus can significantly reduce the photosynthetic capability of plants. Wilting, tissue death, leaf deformity, and abcission are characteristics of prolonged and high-density infestations. The two-spotted spider mite (Tetranychus urticae Koch) can be a problem on chrysanthemums, with some cultivars more sensitive than others. The eight-legged adult emerges after feeding and a final quiescent stage. The two-spotted spider mite, T. urticae Koch (Acari: Tetranychidae), is an important agricultural pest with a global distribution. 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). 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. 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). This mite is polyphagous and attacks the broad range of crops, including soybean, Identifying a mechanism for the development of pesticide resistance is important for advancing pesticide resistance management for arthropod pests. (1995) concluded that better IPM, including the use of economic thresholds and biological control, could reduce the number of applications and delay resistance. There is a winter hibernation period or diapause in temperate or cooler climates, which is a result of the influence of temperature, photoperiod and mite nutrition. Our group developed genomic resources for TSSM, established robust RNAi-reverse Gould (1979) found a small but significant difference in fitness on the original lima bean host after adaptation to cucumber, but Fry (1990) found no difference in survival or fecundity on lima bean after adaptation to tomato. Abstract: Tetranychus urticae is a serious pest of several crops worldwide. 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). They pierce individual cells with their stylets, withdrawing the cell contents. The flecks are only in the epidermal layer of the fruit and do not penetrate beyond this (Brust, 2014). Hot, dry weather is conducive to spider mite outbreaks. This generalist rapidly acclimatizes and adapts to a new host, hereby overcoming nutritional challenges and a novel pallet of constitutive and induced plant defenses. Spider mites damage their host plants while feeding, using MICHAEL P. PARRELLA, ... JOOP VAN LENTEREN, in Handbook of Biological Control, 1999. host plant responses, biotic stress and management strategies for the control of tetranychus urticae koch (acarina: tetranychidae) Tetranychus urticae Koch is a polyphagous pest and attacks broad range of crops, limiting the yield and thus, leading to huge economic losses. (2019). A review of biological control of T. urticae in greenhouses is available (Osborne et al., 1985). The development periods and reproduction of T. … Antixenosis is not a factor in HPR because resistant and susceptible cultivars were equally attractive ( Gould, 1979 ). Developmental times (days) for various stages of two-spotted spider mite, Tetranychus urticae. S.A. Tjosvold, J.F. Gould (1978a) found that adaptation to HPR cultivars of cucumber expressing antibiosis could occur in as little as nine generations. PN, protonymph; DN, deuteronymph; PO, length of time before an adult female begins to oviposit (data from Sabelis, 1981). 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. After a waiting period of up to 3 days, the adult female begins to lay eggs. Flexner et al. As in aphids, the genes for carotene synthesis appear to have been acquired through horizontal gene transfer from a fungus. (eds) Ecology and Evolution of the Acari. Feeding principally on the underside of the leaf, mites leave pinpoint chlorotic spots that turn the leaf bronze when the population is high. put it, plants may “cry for help” when attacked by spider mites and predatory mites come to the rescue. Gerald E. Brust, Tetsuo Gotoh, in Sustainable Management of Arthropod Pests of Tomato, 2018. 5.2) (Sabelis, 1985a,b). This threshold is extremely low and probably not practical for most tomato operations. The larva becomes an eight-legged protonymph, slightly larger than the larva after a quiescent stage. Finally, one important aspect of IRM is the initial proportion of resistance alleles in a population. 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). 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. 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. Under field conditions, multiresistant strains that are resistant to all commercially available acaricides are often encountered, and strikingly these strains also resist compounds with new modes of action that have never been used in the field (Van Leeuwen et al., 2010). [2], Other than certain aphids, T. urticae is the only animal known to be able to synthesise carotenoids. The period during which eggs are deposited can last from 10 days (34 °C) to 40 days (15 °C).

Tetranychus urticae spend most of its life cycle on plant, especially on leaves, and it causes serious damage. As feeding damage progresses a stippled appearance of the foliage is evident. Antixenosis is not a factor in HPR because resistant and susceptible cultivars were equally attractive (Gould, 1979). 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). The lower threshold for development is about 12 °C and the upper limit for development is about 40 °C. 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.

Archives of Phytopathology and Plant Protection: Vol. When a spider mite infestation is discovered, release of 10 predators per 10 plants within infested areas is recommended (Wardlow, 1986). Therefore, this EIL does not lend itself to commercial use. The mite’s feeding causes the mesophyll cells in the area to collapse creating very small white chlorotic spots on the leaves where they have removed the chlorophyll (Fig. 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. Its genome was fully sequenced in 2011, and was the first genome sequence from any chelicerate. T. urticae females apparently are capable of kin recognition and have the ability to avoid inbreeding through mate choice. 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. It performs differentially on diverse host‐plant species. They developed an economic injury level (EIL) based on initial number of mites released on the plant and the number of days mites fed on the plant. Its life cycle consists of eight stages from egg to adult, including three quiescent stages of insensitivity to miticide.
