Western flower thrips are by far the most common thrips on cotton and may be found all season. These mouthparts allow them to pierce a hole in a leaf cell and suck the fluids. Foliar insecticides are recommended when 2-3 thrips per plant are counted and immatures (crème colored and wingless) are present. Thrips are tiny pests that suck the nutrients in plants, leading to devastating effects. Thrips (Thysanoptera: Thripidae) are frequent pests of seedling cotton, Gossypium hirsutum L., in the United States, and can reduce lint yield up to 50% (Cook et al.

Prevention is an easy, cost-effective form of pest management. The thrip's damage can result in yield loss of up to 60% in onions (Allium cepa).In the past few decades, thrip resistance to insecticides with various modes of actions have been documented. Both adult and immature stages of leaf feeding thrips inhabit older leaves and frequently defoliate plants. adjacent cotton fields. Cotton maturity is impacted by several factors, including planting date, varietal maturity, nitrogen rate, irrigation management, and early season pest management of which thrips are the most important. Spatial Distributions of Thrips (Thysanoptera: Thripidae) in Cotton.

Thrips infestations in cotton vary by location, planting date, and year. Excessive feeding results in crinkled malformed true leaves, stunted plants, delayed maturity, reduced yield potential, and in severe cases reduced stands. (2)Department of Plant and Environmental Sciences, Edisto Research and Education Center, Clemson University, Blackville, SC. Each field needs to be scouted on a scheduled weekly basis to be sure no pests are present. 1989) and are commonly found on cotton throughout the season (Leigh 1995). We counted a thrips test today and didn’t find many thrips – of course I was expecting that since it rained the day before. damage caused by thrips in cotton using hyper spectral radiometer at Tamil Nadu Agricultural University, Coimbatore. Thrips will be one of the first pests to scout for in cotton during the growing season. The damage was studied in winter irrigated variety Surabi, with observations taken from 70 to 90 days after sowing at different intervals when incidence of pest was noticed. They have sucking mouthparts, which are the ones responsible for their infestation. Is one product better than the other? Acephate is an effective standard. Author information: (1)Department of Plant and Environmental Sciences, Pee Dee Research and Education Center, Clemson University, Florence, SC. thrips resistant cotton cultivars will lessen the impact on the environment and lower production cost by reducing insecticide application. Damage: With their rasping-sucking mouthparts, thrips dam- age cotton by extracting plant juices from devel-oping buds and foliage. Thrips are a pest of seedling cotton. https://site.extension.uga.edu/brooksag/2014/06/thrips-in-cotton When managing thrips in cotton, prevention is one of the first lines of defense in an integrated pest management program. Thrips and tarnished plant bugs are next on the list of insect pests to be targeted by trait technology in cotton once it is approved for use, which is expected sometime in 2021 . Bud thrips are most common on cotton in arid to semiarid regions. Predatory thrips attack infestations of spider mites, thrips, and whitefly and usually become abundant in late summer. Female thrips are each capable of laying 250 eggs during a two- to three-week period. Acephate, Bidrin, Dimethoate, Intrepid Edge, and Radiant. 2011).Epidermal cells are damaged by feeding of adults and immatures, which leads to malformation and tearing of leaves. Chemical Control Effective chemical control is complicated by the development of insecticide resistance. The bean thrips occasionally appears on cotton in summer, usually at field edges. The ultimate impact of thrips injury on yield is highly variable. The rates above provide consistent control unless western flower thrips (WFT) are also present. By Dr. Moneen Jones, Director, Midwest Master Beekeeper Program on May 27, 2011 • ( 0).
