摘要: The daily flight activity of western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) was examined using color, yellow-light and chemical attractant traps in a cucumber greenhouse and under controlled laboratory conditions. In the greenhouse, flying thrips were most abundant between hours 08:00-10:00, declined at mid-day, and then slightly increased during hours 14:00-16:00; however they decreased to a very low level at 18:00. The use of light traps showed no thrip flight activity during the night. The total number of thrips that flew onto cards on rainy or cloudy days was higher than that on sunny days. We reconfirmed that traps treated with attractant attracted 4.0-9.4 times more thrip than the untreated traps. Under laboratory controlled conditions, thrip flight activity was highest under light intensity between 4 000 and 6 000 lux, air temperature of 28 degrees C, and RH of 70%. In addition, starved thrips flew more readily than non-starved thrips.
