ASOCIADOS A PEUMUS BOLDUS MOL. EN LA RESERVA NACIONAL ISLA MOCHA. CHILE (INSECTA - COLEOPTERA)
Provedor de dados: 72
Autores: Mendoza,Gabriel; Jerez,Viviane.
Se analizó la composición taxonómica de coleópteros epígeos, asociados a la formación vegetal de Peumus boldus presente en la Reserva Nacional Isla Mocha (38º 19' S; 73º 55' W). El estudio se realizó en la primavera y comienzos del verano de 1998, mediante la colocación de 10 trampas Barber a lo largo de un transecto. Cada trampa permaneció en el sitio de muestreo durante 15 días consecutivos y el material recolectado se conservó en alcohol, para su posterior identificación. Los resultados indican que en la formación de P. boldus, el Orden Coleoptera está representado por 15 familias y 25 especies, siendo Germarostes posticus (Ceratocanthidae), Gnathotrupes corthyliformis (Scolytinae) y Aridius chilensis (Lathridiidae) las especies más abundantes. Se...

Ophiostomatoid fungi associated with the spruce bark beetle Ips typographus, including 11 new species from China
Provedor de dados: 16
Autores: Chang, R.; Duong, T.A.; Taerum, S.J.; Wingfield, M.J.; Zhou, X.; Yin, M.; Beer, Z.W. de.
Ips typographus (Coleoptera, Scolytinae) is a spruce-infesting bark beetle that occurs throughout Europe and Asia. The beetle can cause considerable damage, especially when colonized trees are stressed and beetle populations increase. Although some studies have shown that populations of I. typographus in Europe, China and Japan are genetically distinct, these populations are biologically similar, including a strong association with ophiostomatoid fungi. To date, only two Leptographium spp. have been reported from the beetle in China, while 40 species have been reported from Europe and 13 from Japan. The aims of this study were to identify the ophiostomatoid fungal associates of I. typographus in north-eastern China, and to determine whether the fungal...

Escolitídeos como bioindicadores do “declínio do nim” no Brasil
Provedor de dados: 190
Autores: Penteado, Susete do Rocio Chiarello; Carpanezzi, Aparecido Antonio; Neves, Edinelson José Maciel; Santos, Álvaro Figueredo dos; Flechtmann, Carlos Alberto Hector.
Este é o primeiro registro do ataque de besouros (Curculionidae, Scolitinae), no Brasil, causando danos em plantios de nim, entre 7 e 10 anos, em Brejinho de Nazaré, Tocantins, constado em junho de 2009. Os insetos foram identificados como, Xylosandrus compactus (Eichhoff), Cryptocarenus diadematus Eggers, 1937 e Hypothenemus sp. Westwood, 1836. Os plantios atacados apresentavam crescimento abaixo do esperado para a região, baixa produção de sementes, desfolhamento acentuado e rebrota intensa nos ramos, seguida por morte de brotos jovens e/ou do ápice do ramo. A ação dos insetos provocou pontos de exsudação intensa de goma nos orifícios provocados. O fato tem similaridade com a síndrome denominada “declínio do nim”, relatada na África.doi:...

No evidence of coconut stem bleeding disease transmission by bark beetles in Brazil
Provedor de dados: 65
Autores: Guzzo,Elio Cesar; Neves,Jhonatan David Santos das; Santana,Samuel Farias; Negrisoli Junior,Aldomario Santo; Teodoro,Adenir Vieira.
ABSTRACT: Stem bleeding disease, caused by the fungus Thielaviopsis paradoxa is one of the most important diseases of coconut palm Cocos nucifera worldwide and some insect species have been found in association with T. paradoxa infected coconut palms. The present research investigated whether coconut palm-infesting bark beetles (Coleoptera: Curculionidae: Scolytinae) could disseminate stem bleeding disease. Adult bark beetles collected from coconut palms presenting stem bleeding symptoms were inoculated in PDA culture medium. Results showed no germination of the fungus T. paradoxa from either cuticle or digestive tract of bark beetles. Thus, we found no evidence that bark beetles carry viable spores of T. paradoxa that could infect healthy coconut palms...
