Mastigimas anjosi
is an important pest of
Cedrela 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 of
M. anjosi
nymphs, with two sampling methods, yellow sticky traps and direct collections on the leaves of
C. fissilis
trees. The sex ratio of this pest was also assessed. The number of
M. 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 of
Cycloneda sanguinea
,
Hippodamia convergens
adults and
Atopozelus opsimus
nymphs and adults preyed upon
M. anjosi
adults and nymphs on
C. fissilis
leaves in the field.
Mastigimas anjosi
sex ratio was 0.46. Information about sampling methods of
M. anjosi
and its natural enemies is presented and can contribute to the integrated management of this pest in the field.
