Light blue sticky boards for mass trapping of onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), in onion crops: fact or fantasy?

Abstract: In 2001-2002, efficiency of light blue sticky boards for mass trapping of onion thrips (Thrips tabaci Lindeman) in onion crops was investigated. The aim was to reduce the damage caused by thrips on the onion leaves. The lowest percentage of a damaged leaf surface was determined on plants; which were treated twice with deltamethrin. The sticky boards did not prove to be efficient for thrips control. In the drier year 2001, the mean yield of onion was not statistically significantly different between four treatments (insecticide, one sticky board (11.0 x 14.0 cm) per plot (1.5 m2), two sticky boards per plot and control). 2002 was more convenient for onion growing and the highest mean yield was in plants, treated with the insecticide. Though light blue sticky boards were not suitable for thrips control in onion, they were useful for monitoring.
