Comparison of Colored Sticky Traps for Monitoring Thrips Populations (Thysanoptera: Thripidae) in Staked Tomato Fields

Abstract

The response of flower thrips, Frankliniella spp., to various colors and sticky trap designs was evaluated in staked tomato fields in western North Carolina. Yellow sticky traps caught significantly more thrips compared with blue or white traps. There were no differences in the relative proportion of thrips species caught on different colored traps. The size of the flower sampling unit (i.e., 10-flowers versus all flowers per plant) did not influence the correlation between sticky trap catches and thrips abundance in flowers. Only F. occidentalis (Pergande) exhibited a significant correlation between percent abundance on all colors of sticky traps and percent abundance in flowers. Colored sticky traps caught high numbers of F. tritici (Fitch), despite the fact that few F. tritici were collected from flowers. In tests to evaluate different trap designs, cylindrical and cup traps caught more F. tritici than glass slide traps. Cylindrical sticky traps were more economical and enabled easier identification of thrips than glass slide or cup traps.

Attraction of thrips (Thysanoptera: Thripidae and Aeolothripidae) to colored sticky cards in a California avocado orchard

“…We tested white (Gempler'st, Belleville, MI 53508, USA), blue and yellow (both Disposable Stiky Stripst, Olson Products, Medina, OH 44285, USA). These colors were selected for their known attractiveness to various thrips species (Cho et al, 1995;Vernon and Gillespie, 1990;Childers and Brecht, 1996). Clear plexiglass rectangles were coated with Tangle-Trap (The Tanglefoot Company, Grand Rapids, MI 49504, USA) and used as controls to determine capture rates of thrips due to random aerial interception.…”

“…Trap attractiveness and capture rates of thrips vary according to species or guild groupings (Kirk, 1984), trap color (Beckham, 1969;Childers and Brecht, 1996;Cho et al, 1995;Vernon and Gillespie, 1990;Walker, 1974;Yudin et al, 1987), U.V. remittance and fluorescence , trap size and shape (Cho et al, 1995;Coli et al, 1992;Moreno et al, 1984;Lewis, 1959), placement height of traps , sunlight degradation of colors (Childers and Brecht, 1996;Samways, 1986;Grout and Richards, 1990), cardinal direction (Beavers et al, 1971), and geographic latitude (Grout and Richards, 1990).…”

Methods for estimating thrips densities on sticky cards have been developed that may involve either counting a section of a trap (Heinz et al, 1992), or by determining the presence-absence of thrips in grids laid over sticky traps (Steiner et al, 1999).…”

“…The purpose of the work presented here was to determine the preference of S. perseae to sticky traps that were blue, yellow, or white, colors with known attractiveness to thrips (Cho et al, 1995;Vernon and Gillespie, 1990;Childers and Brecht, 1996;Terry, 1997). Clear pieces of plastic coated with sticky adhesive were used as controls to determine rates of random interception independent of trap color.…”

“…and M. invisa attracted S. dorsalis to come, occupy, and possibly breed on the weed. Color attraction research on S. dorsalis revealed that yellowish-green and yellow were the most preferred color compared to blue and white (Tsuchiya et al 1995;Cho et al 1995;Chu et al 2006). Suitable nutrient in term of availability and composition was also another consideration causing S. dorsalis to prefer certain weed species.…”
