“…In our two cowpea greenhouse trials, the main species of thrips was identified to be F. intonsa in each case. Indeed, there are many thrips species infesting different crops in the field, but different species of thrips are attracted to different colors 14 , 19 . To effectively monitor thrips population densities and control different thrips species, first testing different colored cards to screen for optimal color is necessary before applying colored cards in the field.…”

The flower thrips Frankliniella intonsa (Trybom) is one of the most economically important pests in cowpea greenhouses in China. Widespread pesticide resistance of thrips and the negative environmental effects limit the application of pesticides for thrips control. Two commercial cowpea greenhouse experiments were designed to determine the color preference of F. intonsa to colored cards, including white, pink, pale green, light yellow, powder blue, crimson, yellow green, deep sky blue, dark slate blue, dark orange, medium orchid, gold, and black. Clear pieces of plastic were used as the control cards. Additionally, the effects of placement height and orientation (cardinal direction) of the cards were also studied. Both greenhouse trials showed that white cards were significantly more attractive to F. intonsa than the other 13 card colors, followed by deep sky blue cards. White or deep sky blue cards placed low to the ground were found to be most attractive to F. intonsa. Orientation of the colored cards also affected the attractiveness to F. intonsa. The results indicate that white sticky cards were significantly more attractive to F. intonsa than blue cards and therefore can be recommended to monitor F. intonsa population densities and to control them in cowpea greenhouses as part of integrated pest management programs.

“…Two experiments were conducted, one on a farm in Inverness, Florida, in 2009 and another on a farm in Windsor, Florida, in 2010. White traps were used as the standard monitoring tool for thrips because Liburd et al (2009) found them to be an effective device for monitoring thrips in southern highbush blueberries. Arévalo & Liburd (2007) found a strong correlation (r = 0.76) between thrips per flower and thrips per trap in rabbiteye blueberries (Vaccinium virgatum Aiton).…”

“…To determine the effect of insecticides on thrips populations, we deployed a white sticky trap, size 22.8 × 14.2 cm (Great Lakes IPM Vestaburg, Michigan) in the middle of each treatment plot and randomly collected 5 flowerclusters from the blueberry bushes holding the traps. White sticky traps are one of the methods used to sample thrips because it has been shown to be very effective in monitoring thrips population and it is easier to identify the thrips to species on a white background compared with other colored traps [5]. Sticky traps were deployed in the field one week prior to the application of the treatments.…”

Efficacy of Reduced-Risk Insecticides to Control Flower Thrips in Early-Season Blueberries and Their Effect on <i>Orius insidiosus</i>, a Natural Enemy of Flower Thrips

Flower thrips are one of the key pests in production of southern highbush blueberries (Vaccinium corymbosum L. × V. darrowi Camp). They feed on the reproductive parts of the flower and reduce yield. Very few insecticides are available to manage thrips population. Therefore, it is necessary to evaluate pre-existing and experimental insecticides for their efficacy against thrips. There is also a high demand for reduced-risk insecticides that are less toxic to beneficial insects and the environment. In this study, a number of conventional and reduced-risk insecticides were evaluated against flower thrips on farms in Florida and Georgia and in the laboratory. The best performing insecticides were also evaluated in the laboratory for their effects on Orius insidiosus Say, which is a common thrips' predator in Florida. Assail 70WP (Acetamiprid) and SpinTor 2SC (Spinosad) were the most promising insecticides in reducing thrips numbers in the field as well as in laboratory experiments. SpinTor 2SC killed all of the thrips in laboratory arenas within 4 hours of application and showed low toxicity toward O. insidiosus. All of the compounds tested performed as well as the conventional pesticide malathion.
