Susceptibility of Thaumastocoris peregrinus (Hemiptera: Thaumastocoridae), a Eu...
SOLIMAN, E. P.; CASTRO, B. M. de C. e; WILCKEN, C. F.; FIRMINO, A. C.; DAL POGETTO, M. H. F. A.; BARBOSA, L. R.; ZANUNCIO, J. C.Thaumastocoris peregrinus Carpintero and Dellape (Hemiptera: Thaumastocoridae) is a sap-sucking insect that has become a major pest of eucalypts. The entomopathogenic fungi Beauveria bassiana (Bals.-Criv.) Vuill. and Metarhizium anisopliae (Metsch.) Sorokin have the potential to control insect pests. This study evaluated the susceptibility of T. peregrinus to two commercial products based on conidia of B. bassi...
Chemical vs entomopathogenic control of Thaumastocoris peregrinus (Hemiptera: T...
WILCKEN, C. F.; DAL POGETTO, M. H. F. do A.; LIMA, A. C. V.; SOLIMAN, E. P.; FERNANDES, B. V.; SILVA, I. M. da; ZANUNCIO, A. J. V.; BARBOSA, L. R.The Thaumastocoris peregrinus spread to eucalyptus plantations in many countries. Chemical control is a questionable measure, mainly due to the environmental impact, high cost and moreover has the use restricted by the forest certifcations. Bio-insecticides may have similar efciency to chemical products to control T. peregrinus. The chemical thiamethoxam, thiamethoxam+lambda-cyhalothrin, acephate and the microb...
Biological parameters, life table and thermal requirements of Thaumastocoris pe...
BARBOSA, L. R.; SANTOS, F.; SOLIMAN, E. P.; RODRIGUES, A. P.; WILCKEN, C. F.; CAMPOS, J. M.; ZANUNCIO, A. J. V.; ZANUNCIO, J. C.Temperature affects the development, population dynamics, reproduction and population size of insects. Thaumastocoris peregrinus Carpintero et Dellape (Heteroptera: Thaumastocoridae) is a eucalyptus pest. The objective of this study was to determine biological and life table parameters of T. peregrinus on Eucalyptus benthamii at five temperatures (18 °C; 22 °C; 25 °C; 27 °C and 30 °C) with a relative humidity (...
Parasitism of Lepidopteran Defoliators of Urban Plants by Palmistichus elaeisis...
TAVARES, W. de S.; MASSON, M. V.; FERREIRA-FILHO, P. J.; BARBOSA, L. R.; SILVA, W. M.; WILCKEN, C. F.; ZANUNCIO, J. C.Heraclides anchisiades capys (Lepidoptera: Papilionidae), Citioica anthonilis (Lepidoptera: Saturniidae), and Methona themisto (Lepidoptera: Nymphalidae) are tree and shrub pests commonly found in urban areas. The parasitism capacity of Palmistichus elaeisis (Hymenoptera: Eulophidae) was evaluated on pupae of these lepidopteran pests as well as on 2 commonly used alternative hosts, Anticarsia gemmatalis (Lepido...
Longevity and survival of Leptocybe invasa (Hymenoptera: Eulophidae), an invasi...
SOUZA, A. R. de; BARBOSA, L. R.; PASSOS, J. R. de S.; CASTRO, B. M. de C. e; ZANUNCIO, J. C.; WILCKEN, C. F.The blue gum chalcid, Leptocybe invasa Fisher & LaSalle (Hymenoptera: Eulophidae), causes galls on Eucalyptus spp. leaf midribs, petioles and stems. Biological aspects need to be studied to assist in developing management strategies and to maintain this insect in the laboratory to rear the parasitoid Selitrichodes neseri Kelly & La Salle (Hymenoptera: Eulophidae) that depends on having a supply of Eucalyptus se...

BARBOSA, L. R.; RODRIGUES, A. P.; SOUZA, A. R. de; PURETZ, B. de O.; WILCKEN, C. F.; ZANUNCIO, J. C.A vespa-da-galha, Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae), originária da Austrália, pode danificar severamente plantas de eucalipto (Myrtaceae). Este inseto foi registrado em mudas de Eucalyptus grandis em maio de 2015 no município de Treze de Maio, Estado de Santa Catarina, Brasil.; Made available in DSpace on 2018-12-18T23:42:13Z (GMT).

Longevity of Cleruchoides noackae (Hymenoptera: Mymaridae), an egg parasitoid o...
SOUZA, A. R. de; CANDELARIA, M. C.; BARBOSA, L. R.; WILCKEN, C. F.; CAMPOS, J. M.; SERRÃO, J. E.; ZANUNCIO, J. C.Thaumastocoris peregrinus Carpintero and Dellapé (Hemiptera: Thaumastocoridae), damages eucalyptus plants by sucking their sap. This pest can be controlled by releases of the egg parasitoid Cleruchoides noackae Lin and Huber (Hymenoptera: Mymaridae). Increasing the survival of this parasitoid is critically important for its mass rearing in order to release large numbers in integrated programs to manage T. pereg...

BARBOSA, L. R.; RODRIGUES, A. P.; SOLER, L. da S.; FERNANDES, B. V.; CASTRO, B. M. de C. e; WILCKEN, C. F.; ZANUNCIO, J. C.Estratégias eficientes para controlar o percevejo bronzeado Thaumastocoris peregrinus Carpintero e Dellapé (Hemiptera: Thaumastocoridae) não estão disponíveis, mas Cleruchoides noackae Lin e Huber (Hymenoptera: Mymaridae) parasita ovos desta praga. O parasitismo e o número de parasitoides emergidos por ovo de T. peregrinus foram avaliados em laboratório e em ovos desta praga coletados em campo em uma área de, a...

MASSON, M. V.; TAVARES, W. de S.; LOPES, F. de A.; SOUZA, A. R. de; FERREIRA-FILHO, P. J.; BARBOSA, L. R.; WILCKEN, C. F.; ZANUNCIO, J. C.Vespa-da-galha, Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae), causa galhas danosas às espécies de Eucalyptus (Myrtaceae) em várias regiões do mundo, mas tem sido efetivamente controlada por seu parasitoide primário, Selitrichodes neseri Kelly & La Salle (Hymenoptera: Eulophidae). Os objetivos deste estudo foram avaliar a recuperação de S. neseri após sua liberação inicial em plantas de Eucalyptu...
