Mastigimas anjosi is an important pest ofCedrela fissilis in the southeastern and southern regions of Brazil. The objective of the present study was to investigate the effect of the temperature, relative humidity, rainfall and natural enemies on the flight activity of adults and the movement ofM. anjosi nymphs, with two sampling methods, yellow sticky traps and direct collections on the leaves ofC. fissilis trees. The sex ratio of this pest was also assessed. The number ofM. anjosi individuals was negatively correlated with the minimum and maximum temperatures, with a population peak in late May and early June 2017. The numbers of individuals of this psyllid was positively correlated with the relative humidity and rainfall. Larvae and adults ofCycloneda sanguinea ,Hippodamia convergens adults andAtopozelus opsimus nymphs and adults preyed uponM. anjosi adults and nymphs onC. fissilis leaves in the field.Mastigimas anjosi sex ratio was 0.46. Information about sampling methods ofM. anjosi and its natural enemies is presented and can contribute to the integrated management of this pest in the field.
