ABSTRACT
A survey of Scolytidae population of species of Scolytidae family was made in plantations of Eucalyptus camaldulensis Dehnh, Eucalyptus citriodora Hook. f., Eucalyptus pellita F. Muell. and Eucalyptus urophylla S.T. Blake, located at Cuiabá city in Mato Grosso state from march 1998 to february 1999, with aid of ethanol traps model “escolitídeo-Curitiba”. The were used 24 traps, six per Eucalyptus plot/specie. Collection was made every 15 days and divided in two periods: drought (may - October) and rRainy Season (november - april). There were collected a total of 19.153 individuals, distributed in 11 genera and 42 species. In the dry and rain periods there were collected 9.865 and 9.288 individuals, respectively. In plantations of Eucalyptus pellita and Eucalyptus urophylla were collected the largest amount of individuals, in both analyzed periods. Cryptocarenus diademantus Eggers, 1937; Cryptocarenus seriatus Eggers, 1933; Cryptocarenus heveae (Hagedorni, 1912); Hypothenemus obscurus (Fabricius, 1801) and Xyleborus spinosulus (Schedl, 1934) were in number, the most important in plantations of the four species of Eucalyptus.
