Cydianerus latruncularius Perty (Coleoptera: Curculionidae) were observed associated with trumpet trees (Handroanthus spp.) in Brasília, Brazil, in 2019. To contribute with information about their habits and damage, 15 trees (Handroanthus impetiginosus = 7, H. roseoalbus = 4, and Tabebuia rosea = 4) were evaluated and 31 individuals of C. latruncularius were captured, often found within or close to leaf rolls c...
Distributional records in Brazil are provided for two psyllid species, Auchmerina limbatipennis Enderlein, documented for the states of Paraná, Rio de Janeiro, Santa Catarina and São Paulo, and A. tuthilli Klimaszewski, for Paraná and Santa Catarina. Host plants for these species are reported for the first time. A. limbatipennis develops on Inga laurina and I. marginata (Fabaceae), and it displays a dimorphism ...
The eucalypt shoot psyllid, Blastopsylla occidentalis Taylor, 1985 (Hemiptera: Psylloidea), is reported here for the first time from Burundi, Indonesia (Sumatra), Nicaragua, the Philippines and Yemen. The record from Paraguay is shown to be erroneous. New state records are given for the Brazilian states Bahia, Ceará, Piauí and Rio Grande do Sul. Eucalyptus viminalis is listed for the first time as host of B. oc...
Psyllaephagus trioziphagus (Howard, 1885) foi observado pela primeira vez parasitando imaturos de Mastigimas anjosi Burckhardt et al., 2011, com apenas um parasitoide em cada imaturo. Este parasitoide foi previamente reportado desde o Canadá até o Brasil. Apesar de não ser hospedeiro específico, pode representar um agente útil no controle de M. anjosi no Brasil.; Psyllaephagus trioziphagus (Howard, 1885) was fi...
Tetra magnolivora (Keifer, 1939) (Acari, Eriophyidae) new combination was observed infesting Magnolia grandiflora L., in urban areas of Curitiba, Paraná State, Brazil. This mite was observed in high populations on magnolia trees, causing wrinkles, distortion and decreased growth in infested leaves. This is the first record from Brazil for T. magnolivora and we provide new combination.; Tetra magnolivora (Keifer...
The use of silicon in forestry has increased recently as it is directly related to improved resistance to insect pests. The red gum lerp psyllid, Glycaspis brimblecombei, occurs in all eucalypt producing regions in Brazil. Two field experiments were conducted to study the effect of silicon applied to Eucalyptus camaldulensis on the psyllid population. In the first experiment, the applications were made via soil...
Psyllaephagus trioziphagus (Howard, 1885) was first observed feeding from Mastigimas anjosi Burckhardt et al., 2011 immatures, with just one parasitoid on each insect. This parasitoid was previously reported from Canada to Brazil. Although it is not host-specific, it may be a useful agent to control M. anjosi in Brazil.; Psyllaephagus trioziphagus (Howard, 1885) foi observado pela primeira vez parasitando imatu...
The objective of this work was to evaluate the different resistance of commercial E. camaldulensis and E. urophylla clones to the attack of (Glycaspis brimblecombei) Moore (Hemiptera: Aphalaridae). The experiment was carried out between May of 2007 and April of 2008, in João Pinheiro, Minas Gerais State, Brazil, with 5 clones of E. camaldulensis and 5 of E. urophylla. The experimental design was randomized bloc...
Glycaspis brimblecombei Moore, 1964, (Hemiptera: Psyllidae) is an insect of Australian origin which can cause severe damage on the production of different species of Eucalyptus. In Brazil, its presence was first described in the State of Sao Paulo in 2003 and it is present in several states such as Paraná, Goiás, Minas Gerais, Santa Catarina, Rio Grande do Sul, Espírito Santo and Bahia. The occurrence of this i...
