Control of the blueberry thrips complex in lowbush blueberry is difficult. Growers rely on timing a foliage protectant insecticide with emergence of overwintered thrips. Plant phenology is currently used as a basis for timing insecticide applications. However, thrips emergence is not always well synchronized with plant phenological development. We have been assessing the use of colored sticky traps for monitoring thrips emergence. In 1999 and 2000 blue sticky cards were evaluated for monitoring emergence of blueberry thrips in pruned fields. Trap captures and plant colonization by thrips was not consistent. A field trial in 2003 was conducted to determine the attractiveness of white, yellow, and blue sticky traps to the blueberry thrips complex.
