“…Tomatoes grown on UV-reßective mulch tend to have lower populations of adult F. occidentalis early in the season compared with those grown on black plastic mulch (Riley andPappu 2000, Stavisky et al 2002). Similar seasonal trends between UV-reßective and black mulch have been found for adults of other thrips species in tomatoes (Scott et al 1989). Kring and Schuster (1992) argued that UV-reßective mulches should have longer lasting repellent effects in pepper than in tomato, because peppers are smaller and cover less of the mulch surface than larger tomato plants.…”

In a 2-yr study, the impacts of different plastic soil mulches, insecticides, and predator releases on Frankliniella thrips and their natural enemies were investigated in field-grown peppers. Ultraviolet light (UV)-reflective mulch significantly reduced early season abundance of adult thrips compared with standard black plastic mulch. This difference diminished as the growing seasons progressed. Late season abundance of thrips larvae was higher in UV reflective mulch compared with black mulch plots. The abundance of the predator Orius insidiosus (Say) was significantly lower in UV-reflective mulch compared with black mulch treatments. Infection of plants with tomato spotted wilt virus, a pathogen vectored by Frankliniella occidentalis (Pergande), was <6%. In the year with the higher disease incidence (2000), UV-reflective mulch plots had significantly less disease (1.9%) compared with black mulch plots (4.4%). Yield was significantly higher in UV-reflective mulch (24,529 kg/ha) compared with black mulch (15,315 kg/ha) during this year. Effects of insecticides varied with species of thrips. Spinosad reduced abundance of F. occidentalis, but not Frankliniella tritici. In contrast, esfenvalerate and acephate reduced numbers of F. tritici and Frankliniella bispinosa, but resulted in higher populations of F. occidentalis. Spinosad was the least disruptive insecticide to populations of O. insidiosus. Releases of O. insidiosus and Geocoris punctipes (Say) reduced populations of thrips immediately after releases; naturally occurring predators probably provided late season control of thrips. Our results suggest that UV-reflective mulch, combined with early season applications of spinosad, can effectively reduce abundance of thrips in field-grown pepper.

“…The selective sensitivity of thrips to different UV ranges becomes obvious when we compare our results with reports on the use of UV-reßective mulches against thrips. Some reports are available for tomato and capsicum crops, where use of UV-reßective mulch caused signiÞcant reduction in WFT, F. occidentalis (Pergrande) population (Scott et al 1989, Greenough et al 1990, Brown and Brown 1992, Kring and Schuster 1992, Vos et al 1995, Costa et al 2002, Stavisky et al 2002, Gonzalez 2004. Similarly, other species of thrips were repelled using plastic reßective mulches in outdoor ornamentals and vegetable crops (Csizinski et al 1995, Terry 1997.…”

We studied the effect of UV-blocked greenhouses made from netting and plastics on the movement and pest status of three important pest of tomatoes: whiteßy (Bemisia tabaci), thrips (Ceratothripoides claratris), and aphid (Aphis gossypii). Under UV-blocked greenhouses, fewer whiteßies, aphids, and thrips entered the greenhouse compared with the ones having more UV intensity. Similarly, signiÞcantly fewer alate aphids and adult B. tabaci/leaf were counted in greenhouses with low UV intensity. Although thrips were the most abundant pest, they also were signiÞcantly less abundant in greenhouses with lower UV intensity. Consequently, signiÞcantly lower levels of leaf infestation were recorded under these greenhouse conditions. During open gates experiments, virus infection levels reached 96 Ð100% under UV nonblocking greenhouses compared with 6 Ð10% infection levels in greenhouses where UV irradiation was blocked. In addition, the appearance of virus symptoms was considerably delayed under greenhouses made from the UV-blocking roof material, although the majority of the plants tested positive for the tospovirus, capsicum chlorosis virus (CaCV; AIT isolate). The results are discussed in context of improved management of sucking insect pests of tomatoes in the humid tropics.

“…Western flower thrips are believed to prefer flowers which have dense inflorescences (Bailey, 1933). Response of thrips, including WFT, to colour has been studied by several workers (e.g., Brodsgaard, 1989a,b;Yudin et al, 1987;Scott et al, 1989;Teulon & Penman, 1992). Blue, low ultra-violet reflective white, yellow and blue-violet traps are more attractive to WFT than green, red, orange, black and high ultraviolet reflective white traps.…”

Flower preference behaviour of western flower thrips in the Similkameen Valley, British Columbia, Canada

Western flower thrips (WFT), Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), occur on most wildflowers, weed and ground cover flowers in the southern interior of B.C., Canada. Preference by WFT for naturally occurring ground cover blooms was determined in a series of choice trials aimed to examine the potential of using such flowers as trap crops under nectarine trees. The effect of height of flowers above ground level within an orchard was also examined to determine whether this may affect flower attractiveness. Although WFT showed consistent preferences for various flower types, no ground cover grown presently in this region appeared to have potential as an effective trap crop. The density of WFT landing on less preferred flower types was not reduced when more attractive flowers also were present, and WFT were found to distribute evenly over all flowers available. Western flower thrips responded to the density of flowers only in response to highly scented flowers, and were attracted equally to mixtures of colours and single colours of flowers. There was a consistent preference by WFT in the spring for flowers located at ground level.
