The aim of this study was to evaluate the population dynamics of Thaumastocoris peregrinus (Hemiptera: Thaumastocoridae), Glycaspis brimblecombei (Hemiptera: Aphalaridae) and its parasitoid Psyllaephagus bliteus (Hymenoptera: Encyrtidae) in three distinct regions of São Paulo State (Mogi Guaçu, São Simão, and Altinópolis) during 2014 to 2017. The pests and parasitoid monitoringwas correlated with meteorological data: maximum temperature (Tmax.), minimum temperature (Tmin.) and average (Tmed.); rainfall (P); daily solar radiation (R) and vapor pressure deficit (DPV). The insects monitoring was carried out with yellow stick traps (12.5 x 10 cm) monthly during for four years, totaling 275 sample sites. T. peregrinus population index declined over the years, differing from G. brimblecombei and P. bliteus, which ones increased. The correlation between T. peregrinus and meteorological data was positive with the considering Tmax., Tméd., R and DPV. Rainfall and Tmin. was negative for G. brimblecombei, but positively for Tmax., R and DPV. P. bliteus population had positive correlation for the population increasing and Tmax., R and DPV. These results were similar to field observations, demonstrating monitoring may be essential in decision making for pest control.
