Abstract

Background. The red gum lerp psyllid Glycaspis brimblecombei Moore (Hemiptera: Psyllidae), an eucalypt insect pest from Australia, was reported in Brazil in 2003. This study evaluated damage patterns of this pest and the parasitism rates of Psyllaephagus bliteus (Hymenoptera: Encyrtidae) on E. camaldulensis and its hybrids E. urophylla X E. camaldulensis and E. urophylla X E. grandis. Methods. Plantation plots of three eucalypt genotypes were evaluated over one year. The eucalypt leaves were collected and examined. Results. Damage by G. brimblecombei was lower on the hybrid genotypes and on the adaxial surface of the eucalypt leaves. Glycaspis brimblecombei egg and nymph density correlated negatively with monthly rainfall. Nymph parasitism by P. bliteus was low (2.9%) independent of genotype and did not vary throughout the year. Discussion. The use of less susceptible eucalypt genotypes (e.g., hybrids) seems to be an alternative to G. brimblecombei management because mortality rates for this pest resulting from P. bliteus parasitism were low.
