However, these control agents help reduce thrips numbers at the infestation source, such as small grains and weeds, before they migrate into the cotton field. Remember that cotton is most sensitive to thrips damage when the 1 st true leaf begins to appear between the … 2017 Jan;162(1):30–40. Rummel DR, Quisenberry JE. Annals of the Entomological Society of America. Plant bugs ( Lygus spp.) Greg Brown says: October 16, 2015 at 9:15 am . The species composition of adult thrips varied among all locations which included trials within Arkansas 80 0 obj <> endobj Despite these hurdles, advances in genetic engineering have produced a cotton trait that uses antixenosis to deter injury from thrips.24 Cotton with this trait is expected to be commercially available in 2022. Cotton thrips infestation predictor: a practical tool for predicting tobacco thrips (. Base the decision to apply an insecticide on the number of thrips present and the stage of plant development. However, western flower thrips is regarded to be a 'pesticide-induced problem', having developed resistance to pesticides from different chemical classes. Watts JG. Ratings ‘1’ through ‘5’ represent advancing injury to true leaves, with ‘0’ indicating no visible injury. Akbar W, Gowda A, Ahrens JE, Stelzer JW, Brown RS, Bollman SL, Greenplate JT, Gore J, Catchot AL, Lorenz G, Stewart SD. Image credit: Sophia Conzemius, Clemson University. 109 0 obj <>stream Imidacloprid (Bayer Advanced Tree & Shrub Insect Control, Merit) commonly fails to provide satisfactory thrips control, and imidacloprid generally is not recommended for thrips. Foliar insecticide applications are often required to control thrips in cotton as the plant continues to grow, representing a shift to reactive control rather than preventative. ������D0���b T���/ Cover crop, rye residue and in‐furrow treatment effects on thrips. Tobacco thrips can be identified using genetic techniques3 or by visual characteristics using a microscope.3,5 As adults, tobacco thrips have large, fully functioning (macropterous) or rudimentary (brachypterous) wings and bodies about 1 to 2 mm in length that can be dark brown or tan (figures 2 and 3). Wang H, Kennedy G, Reay-Jones FPF, Reisig DR, Toews MD, Roberts PM, Herbert DA, Taylor S, Jacobson AL, Greene JK. Crop science. Registration of Arkot 8727, a high glanding cotton germplasm line. Influence of thrips injury on leaf development and yield of various cotton genotypes. They are resistant to most pesticides and feed deep within the flower head or on developing leaves. Thrips can migrate in great numbers … I am up to a professional applicator responsibility and accountability. Journal of economic entomology. For example, delaying the planting date can reduce the risk of thrips injury.13 A mathematical model9 and web-based tool,15 the Cotton Infestation Predictor Tool, is available to help cotton producers determine appropriate planting dates to minimize risk from tobacco thrips.

Resistance to certain organophosphate, carbamate, and synthetic pyrethroid insecticides has been documented in populations of western flower thrips. Preventive in-furrow or seed treatments usually provide adequate thrips control until the second true-leaf stage. However, Upland cotton is generally considered highly susceptible to thrips, with no known thrips-resistant commercial varieties.2,16 Some cotton species appear to be more resistant or tolerant of thrips, such as Pima cotton, Gossypium barbadense L.16,17 Contradictive traits such as highly pubescent18 and hairless19 phenotypes have been linked with reduced thrips populations, yet both have been reported to be susceptible characteristics in other studies.20,21 The high glanding breeding line ‘Arkot 8727’ has been registered with thrips resistance22, though glandless cotton was found to have lower thrips damage.23 Additional genetic and chemical analyses are needed before traditional plant breeding techniques will yield HPR characteristics in cotton that can be used as a successful management practice for thrips in the Southeast. New Chemical Control Option for Thrips and Whitefly. The neonicotinoids11 thiamethoxam and imidacloprid, the organophosphate11 acephate, and the carbamate11 thiodicarb are commonly used as seed treatments.

Khaliq A, Afzal M, Khan AA, Raza AM, Kamran M, Tahir HM, Aqeel MA, Ullah MI. and thrips (Thrips spp.) However, these control agents help reduce thrips numbers at the infestation source, such as small grains and weeds, before they migrate into the cotton field. This will not provide control of the thrips, but it will let you know if a plant is becoming infested. (eds. Additional cultural control practices for managing thrips in seedling cotton are contradictive or deficient. Control decisions: To scout for thrips, a cardboard box lined with white paper is recom-mended to spot these small insects (less than 1⁄20 inch in length) in the field. Eggs of thrips (figure 5) are partially inserted into leaf tissue. Entomol. Adult male WFT are light yellow, while adult female WFT are a little larger than the males and vary in color from light yellow, yellow with brown splotches, to dark brown. % 쏢 Clean cultivation and destruction of crop residues (fallen leaves, twigs etc.) Shaking plants over or onto something dark, such as a black drop cloth or clipboard, is an excellent method for enumerating light-colored immature thrips (watch a thrips YouTube video that shows the methods of sampling for thrips). They also superficially resemble some other thrips species that, if mistaken, may result in poor control because the insecticides selected may not be efficient against chilli thrips. Olson DM, Davis RF, Brown SL, Roberts P, Phatak SC. 120SC also gave thrips control over 75% and were also statistically on a par with each other. Miyazaki J, Stiller WN, Wilson LJ. Marshall MW, Williams P, Nafchi AM, Maja JM, Payero J, Mueller J, Khalilian A. A good integrated pest management (IPM) strategy will use several of the aforementioned control tactics and BMPs concurrently.40. 34 p. D’Ambrosio DA, Huseth AS, Kennedy GG. Olson DM, Davis RF, Brown SL, Roberts P, Phatak SC. Iran Agricultural Research. Producers and managers of cotton in the southeastern United States should consider using a multi-tactic approach that uses several BMPs in an overall IPM approach for managing thrips. Genetic variation and comparative analysis of thrips resistance in glandless and glanded cotton under field conditions. Cover crop, rye residue and in‐furrow treatment effects on thrips. Pesticides are often used to control western flower thrips (Frankliniella occidentalis) in horticultural crops. 2018 Apr:1(2):892–898. Chlorphenapyr 360SC proved the least effective in controlling thrips with only 63.13% mortality. 1961 Feb;54(1):77–9. However, since the establishment of western flower thrips (WFT), Frankliniella occidentalis, in Western Australia in 1993, this has become the more important pest in strawberries. Begin inspections once the cotton reaches approximately 50 percent stand emergence. Historically, the plague thrips, Thrips imaginis, was considered to be the main thrips pest of strawberries. Arif MJ, Gogi MD, Mirza M, Zia K, Hafeez F. Impact of plant spacing and abiotic factors on population dynamics of sucking insect pests of cotton. Populations typically peak within 4 weeks of plant emergence. Clemson (SC): Clemson University, Clemson Cooperative Extension; 2020. p. 105–118. Thrips in Greenhouse Crops - Biology, Damage and Management Chemical control of western flower thrips can be difficult. Thus, seed or foliar-applied chemical insecticides are typically required to protect cotton from these pest groups. However, western flower thrips is regarded to be a 'pesticide-induced problem', having developed resistance to pesticides from different chemical classes. The use of any brand names and any mention or listing of commercial products or services in this publication does not imply endorsement by Clemson University nor does it imply discrimination against similar products or services not mentioned. Consider spraying only if 10 thrips per blossom are found when flowers are shaken onto a flat dark-colored surface and thrips are counted. Treatment is only recommended if the following conditions are met: Infestation levels are “relatively high” Plants do not have adequate moisture Mummifying parasites are not present Fungal pathogens are not present … cotton for tobacco thrips control; it was as effective as Orthene®, an organophosphate chemical insecticide commonly referred to as acephate. The information in this publication is provided for educational and informational purposes only. 2011. Manag. and thrips (Thrips spp.) Parajulee MN, Shrestha RB, Slosser JE, Bordovsky DG. Last year, most of the cotton in Mississippi was sprayed for thrips at least one time and many fields were sprayed multiple times, even behind a seed treatment. ;�O�#� Xx�O These insecticides systemically enter a seedling cotton plant through water uptake in the root system and control thrips that feed on above-ground tissue. Bourland FM, Benson NR. Not much has changed since last year in regards to thrips control via insecticide seed treatment. When thresholds are met or exceeded, options for foliar sprays of insecticides include, but are not limited to, the organophosphates acephate, dicrotophos, dimethoate, and the spinosyn11 spinetoram as the most efficacious materials available for post-planting control of thrips in seedling cotton. Across most of the Cotton Belt, thrips are considered the number one pest of seedling cotton. June 3, 2020 June 8, 2020 Sarah Jandricic, Greenhouse Floriculture IPM Specialist, OMAFRA. Lowercase ‘i’ in Times New Roman 12-point font for comparison with (from left to right) two adults (female with macropterous [large, functioning wings] and male with brachypterous [rudimentary, non-functioning wings]), pupa, prepupa, and two immatures (also referred to as ‘nymphs’ or ‘larvae’) of tobacco thrips. A web-based tool for predicting risk from tobacco thrips in cotton. Kennedy G, Chappell T, Ward R, DePolt K. Thrips Infestation Predictor for Cotton. The use of barriers, sound waves, electricity, radiation, temperature, and other physical control tactics has not been reported as effective in controlling thrips in seedling cotton.

A comparison of the life cycles of, Chappell TM, Ward RV, DePolt KT, Roberts PM, Greene JK, Kennedy GG. 30 p. Issued March 2020. Delay will allow thrips to enter the opening flowers and reduce exposure to the insecticide. Cultural control strategies, such as the use of cover crops, reduced tillage operations, delayed planting date, targeted irrigation, and starter fertilizer, can complement chemical control and likely help slow the development of insecticide resistance. Although a complex of species infests seedling cotton in the region, tobacco thrips are the predominant species requiring management in the crop. Cotton seedlings (7-leaf stage) without (left) and with (right) preventative insecticide used at planting. Recommendations for the use of agricultural chemicals may be included in this publication as a convenience to the reader. Thrips are part of the order Thysanoptera, and are common garden pests that suck plant juices and sometimes spread viruses. This is best achieved by treating the block at maximum bud swell or onset of full bloom. 1995 Feb;24(1):58-67. Mississippi State (MS): Mississippi State University; 2006 Bulletin 1156.

NC State Extension Research Specialist Dr. Dominic Reisig addresses thrips control in cotton as a part of the CHROME Regional Ag Expo. Entomologia Experimentalis et Applicata. Cotton aphid fungus (black spots). Admire (0.1 and 0.05 lb a.i./acre), Adage, Temik (0.75 and 0.53 lb a.i./acre) and Gaucho (6 fl oz a.i./acre) provided high levels of control of thrips. Identification & Monitoring: Adults and nymphs infest the underside of cotyledons, young leaves and growing points, rasp the plant surface and suck out the cell contents: affected areas are silvery-white; younger leaves become distorted; growing points can die. Greene JK. Chemical Control and Action Thresholds. Cotton aphid mummies (large, pink and round) from parasitism. Acephate and imidacloprid can also be applied as in-furrow liquid sprays, and the organophosphate phorate and the carbamate aldicarb are applied as in-furrow granular insecticides. Because most tobacco thrips populations are resistant to the neonicotinoid-group insecticide seed treatments, there has been a lot of renewed interest in different at-planting insecticides. Pest management science. 2011 Mar;36(1):21–39. are two of the most economically important insect pest groups impacting cotton production in the USA today, but are not controlled by current transgenic cotton varieties. 1979 Oct;72(5):706–709.

Pakistan Journal of Biological Sciences. Other strategies for controlling thrips in cotton include practices deployed as cultural techniques. Aphids in preblooming cotton, from emergence to first bloom, rarely develop to economically damaging levels, and many insecticidal seed treatments can affect aphids for up to 30 days after planting. p. 61–70. Cotton aphids have been more prevalent than normal this year in NC. The neonicotinoid insecticidal class currently contains seven chemicals; however, only two of these are labeled for thrips control in cotton, namely, imidacloprid and thiamethoxam (Syngenta 2012).

In Parker BL, Skinner M, Lewis T. Thrips are also vectors of tobacco streak virus and tomato spotted wilt virus. Heavy plant residue at the time of cotton planting can also reduce thrips populations and damage to cotton. J. Concern about thrips resistance to neonicotinoid insecticides (the active ingredient in Admire Pro and insecticidal seed treatments) has generated lots of questions about managing damage on susceptible cotton. All thrips inhabit secluded areas on plants, such as unopened flower and terminal buds, which reduces exposure to insecticide applications. The western flower thrips (WFT), Frankiliniella occidentalis is a recent exotic invader also found in cotton regions. Registered under the trade name AgLogic 15G, this new product is expected to equal Temik. and thrips (Thrips spp.) They can become serious pests indoors, outdoors and in greenhouse settings. Thank you Raymond.Good … Parasitoids, predators, and disease organisms can provide natural biological control of thrips, but it is almost always not enough protection to prevent infestations of thrips from having an economic impact. The presence of numerous immature thrips suggests that the at-plant insecticide is no longer providing acceptable control (i.e. 61-70. Numerical ratings of progressive feeding injury to cotton seedlings caused by thrips. Not much has changed since last year in regards to thrips control via insecticide seed treatment. (Aeris®) or thiamethoxam (Avicta Complete Cotton®), in-furrow applications of the insecticide aldicarb (Temik®), and an untreated control (no at-planting insecticide).
