Keywords:
Crickets, Eucalyptus, insecta, initial pestAbstract
Damages caused by Gryllus sp. in young seedlings of Eucalyptus grandis were analysed. Threeexperimental groups were tested: Group 1 with 7 days-old and stem diameter of 2.5 mm seedlings; Group 2
with 49 days-old and 3.33 mm diameter seedlings; and Group 3 with 80 day-old and diameter of 5.75 mm. Each
group consisted of 12 plants isolated in a cage with a couple of crickets for 15 days. The following daily evaluations
were made: absence of damage; superficial signs of chewing; deep signs of chewing and stem cuts. Diameter and
age influenced the occurrence and intensity of damage.
