Timing of the Attraction of Melon Thrips, Thrips palmi(Thysanoptera: Thripidae), to Reflective-type Traps Combined with Blue Sticky Board and a Blue LED Array

Abstract

Abstract:The attraction of melon thrips, Thrips palmi Karny Thysanoptera: Thripidae , to reflective-type traps combined with blue sticky board and a blue light emitting diode LED array was investigated in July 2011 in an eggplant greenhouse. The peak wavelength of the blue LED array was 470 nm. The LED array was placed close to the plants and directed toward the sticky board. The number of adult thrips caught by the reflective-type trap at a light intensity of 3 10 17 photons/ m 2 ·s was significantly greater than the number caught by the control, a non-illuminated trap. Furthermore, the number of adult thrips caught by the reflective-type trap was significantly greater than that for the control during 18:00-21:00 and 21:00-0:00. Additionally, significantly more female adult thrips were caught by the reflective-type trap than by the non-illuminated trap, especially during the 18:00-21:00 time period.

Activity Patterns, Population Dynamics, and Spatial Distribution of the Stick Tea Thrips, Dendrothrips minowai, in Tea Plantations

“…The flight heights of D. minowai adults were evaluated using commercially available colored sticky traps. Blue sticky traps were used because they have been shown to be effective in attracting various other thrips species [ 25 , 26 ]. Traps were hung on branches at various heights below (negative numbers) and above (positive numbers) the position of tender tea leaves at the top of the tea plant (−35, −30, −25, −20, −15, −10, −5, 0, 5, 10, 15, 20, 25, 30, and 35 cm from the position of tender tea leaves at the top of the tea plant canopy; Figure 2 a), and each trap was separated by a distance of at least 5 m. Five traps at each height (treatments) were placed randomly throughout organic tea plantations of Shaoxing Royal Tea Village Co., Ltd., from 2 May to 4 May 2022.…”

“…Other techniques are used to monitor the number of thrips in order to establish the level and distribution of thrips infestation in a crop, such as the use of sticky traps, alone or with lures or pheromones, water pan traps, sampling of leaves and leaf beating. Monitoring results can be used to establish the distribution in a crop, to establish economic threshold levels and to facilitate the decisionmaking for which and when measures need to be taken to manage T. palmi infestations (S anchez et al, 2011;Nakamura et al, 2014;Shibao and Tanaka, 2014;Thongjua et al, 2015;Dong and Hsiu, 2019).…”
