“…Reported thrips developmental minimum temperature thresholds vary for different thrips species (Edelson, 1988; Lowry et al., 1992; van Rijn et al., 1995). In this study, although we encountered multiple thrips species, over 75% of them were western flower thrips (Suenkel et al., 2021), which agrees with previous reports by Chambers and Sites (1989) and Rummel and Arnold (1989) that the western flower thrips were the most dominant thrips in the Texas High Plains. Thus, for the degree‐day calculation, we used the minimum developmental threshold temperature of F. occidentalis as described by van Rijn et al.…”

“…In contrast, in the Texas High Plains, green annual vegetation that is commonly reported to serve as green bridges for thrips in the southeastern USA and south Texas during the winter months is virtually absent because of the prolonged periods of below‐freezing temperatures. However, in data collected during January and February, Chambers and Sites (1989) reported wheat and alfalfa with their associated soils to be the primary winter survival hosts for thrips in 10 counties of the southern Texas High Plains where the average low and high temperature is ‐1–1 and 14–16°C, respectively (https://www.usclimatedata.com).…”

The incidence of thrips in the High Plains of Texas (USA) was investigated using sticky traps during the 2021 and 2022 seasons. Yellow sticky traps were placed in wheat fields and collected and replaced weekly and thrips were counted under a dissecting scope. Weekly wheat reflectance measurements were taken using a hyperspectral radiometer from which normalized difference vegetation index (NDVI) was calculated for each measurement. Temperature (degree day) and NDVI values were then related to weekly thrips incidence using regression. Thrips incidence curvilinearly increased over time during each of the two seasons and reached a maximum in the middle of June, after which it declined sharply. There was a strong positive relationship between degree days and thrips incidence until the incidence reached a maximum, whereas the incidence was negatively related to NDVI values. Analysis of the thrips changes over time progress with the two variables together showed that degree day has greater impact on thrips incidence than NDVI. However, the steep decline in thrips abundance after its peak in mid‐June suggests that senesced wheat fields with NDVI values near zero are not significant sources of thrips, signifying the importance of wheat growth stages in the seasonal population dynamics of thrips. Overall, the 2‐year results were generally consistent in trends of thrips incidence during the season, which may need to be considered when choosing vegetable planting dates in the region.

“…These observations are in accordance with Dhaka and Pareek (2008) who reported the incidence of whitefly at its peak at later stages of cotton crop. Thrips also showed almost same pattern of gradually increased numbers (0.67 ± 0.50 to 1.97 ± 0.12) from June to end of July 2018 as studied by Cook et al (2011) and Cook et al (2013), however Albeldano et al (2008) has some different findings that thrips causes more damages during early season and early stages of cotton, but their findings are about ratio of damages not for the population dynamics. Same trend was also recoded for jassid population (1.42 ± 0.08 to 3.00 ± 0.12) round the Border crops and surroundings habitats also have significant effects on populations of sucking insect pest populations of cotton field plots.…”

Sucking pests are major threat to cotton field crop which cause unbearable losses to the crop yield. Aim of the current study was to record seasonal dynamics of major sucking insect pests including whitefly, jassid, thrips and their natural arthropod predators i.e. green lacewings and spiders in cotton field plots. The effects of surrounding field crops on pests’ density and predatory efficiency of predators were also recorded. For sampling and survey of insects, the visual counting was found to be the most efficient method for recording the abundance of insects, trailed by net sweeping and tapping. Whitefly was the most dominant sucking pest found on the vegetative stage of cotton, followed by jassid and thrips. Fluctuated populations of predatory arthropods, spiders and green lacewings were also recorded during whole cropping season however, the densities of pests and predators varied with crop phenology. Spiders’ population was encouraging at both vegetative and flowering stage and also the same trend of jassid and whitefly were observed at both stages of the crop. Surrounding habitats showed non-significant effect on population densities of insect pests and predators. For abiotic factors, the spiders showed strong positive correlation with humidity and temperature. However, green lacewing was only positively correlated with humidity. On the other hand, the populations of whitefly, jassid and thrips showed non-significant correlation with both temperature and humidity. Overall densities of sucking insect pests were found above economic threshold level. The plant age, crop stage and surrounding habitats effect on the population fluctuation of pests as well as the predators’ abundance. The future studies are also warranted to investigate the altered habitats and multiple trap cropping to find out their impact on unattended insect predators and parasitoids in cotton crop.

“…Upland cotton, Gossypium hirsutum L., is a major commodity grown in the southern U.S., and thrips can be found infesting cotton throughout this region. The most common species found in cotton include tobacco thrips, Frankliniella fusca (Hinds) (Thysanoptera: Thripidae); flower thrips, Frankliniella tritici (Fitch) (Thysanoptera: Thripidae); western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae); onion thrips (Thysanoptera: Thripidae), Thrips tabaci (Lindeman); and soybean thrips, Neohydatothrips variabilis (Beach) (Thysanoptera: Thripidae) ( Cook et al 2003 , Albeldaño et al 2008 , Stewart et al 2013 ). Of these species, tobacco thrips is the most abundant in seedling cotton in the Mid-South (Arkansas, Tennessee, Missouri, Mississippi, Louisiana) and the majority of the southeast (Virginia, North Carolina, South Carolina, Georgia, Alabama, Florida) ( Cook et al 2003 , Stewart et al 2013 ).…”

Foliar-applied insecticide treatments may be necessary to manage thrips in cotton (Gossypium hirsutum L.) under severe infestations or when at-planting insecticide seed treatments do not provide satisfactory protection. The most common foliar-applied insecticide is acephate. Field observations in Tennessee suggest that the performance of acephate has declined. Thus, the first objective was to perform leaf-dip bioassays to assess if tobacco thrips, Frankliniella fusca (Hinds) (Thysanoptera: Thripidae), in cotton production regions have evolved resistance to foliar-applied insecticides. A second objective was to assess the performance of commonly applied foliar insecticides for managing thrips in standardized field trials in Arkansas, Tennessee, Mississippi, and Texas. For both objectives, several insecticides were evaluated including acephate, dicrotophos, dimethoate, lambda-cyhalothrin, imidacloprid, and spinetoram. Field trials and bioassays were completed from 2018 to 2021. Dose-response bioassays with acephate were performed on tobacco thrips field populations and a susceptible laboratory population. Bioassay results suggest that tobacco thrips have developed resistance to acephate and other organophosphate insecticides; however, this resistance seems to be most severe in Arkansas, Tennessee, and the Delta region of Mississippi. Resistance to other classes of insecticides were perhaps even more evident in these bioassays. The performance of these insecticides in field trials was variable, with tobacco thrips only showing consistent signs of resistance to lambda-cyhalothrin. However, it is evident that many populations of tobacco thrips are resistant to multiple classes of insecticides. Further research is needed to determine heritability and resistance mechanism(s).
