P.  aPopulation fluctuation of thrips in Moericke traps of different colors in semi-hydroponic strawberry cultivation.h[electronic resource]  c2023  aThrips are main strawberry insect pests and the use of traps is a practical and low-cost method to capture and monitor them. This study aimed to evaluate the population fluctuation and the efficiency of colored Moericke traps in capturing thrips in semi-hydroponic San Andreas strawberry cultivation in Ca??ador, Brazil. From October 2019 to October 2021, thrips were collected using Moericke traps made with white, yellow, and blue colored bowls. The traps were distributed randomly, with four replications per color, arranged at the same height as the cultivation bench. To count the thrips, 20mL water samples were collected weekly from the bottom of each bowl. The data were transformed into ln(x) and the means were compared using the Tukey test (p≤0.05). Count data and meteorological variables were submitted to Pearson's correlation analysis (p≤0.01 and 0.05) using Student?s t-test. We found that the thrips population increases in early spring (September and October), with population peaks in summer (January, February, and March). In July, the population reduces due to the decreased temperatures. The blue colored trap was the most efficient in capturing thrips. Weekly monitoring of thrips with Moericke trap allows the observation of population peaks and helps in decision-making for pest control in semi-hydroponic strawberry cultivation.  aFragaria ?? ananassa  aIntegrated pest management  aMonitoring  aThysanoptera1 aWAMSER, A.
