Abstract In agricultural crops, colored traps are often used to monitor the density of thrips (Thysanoptera: Thripidae), important pests and vectors of viral diseases. We used colored pole traps, mounted on wind vanes, to study thrips approach in two countries. In Israel, during periods of low wind speed (<1.1 km h ‐1 ), 77% of western flower thrips, Frankliniella occidentalis (Pergande), reached the leeward side of traps by actively flying upwind. In New Zealand, during periods of high wind speed (>9 km h ‐1 ), 83% of onion thrips, Thrips tabaci Lindeman, reached the windward side of traps passively. Consequences of these results for thrips monitoring are discussed.
