ABSTRACT
Eucalyptus spp. plantations represent >60% of the reforested area in Brazil. Although ambrosia beetle attacks on live trees were at first nonexistent, they have begun to appear with greater frequency. Monitoring for pest insects is a key factor in integrated pest management, and baited traps are one of the most widely used methods for insect population detection and survey. We compared the efficiency of the most widely used trap in Brazil to survey for ambrosia beetles and other Scolytidae, the ESALQ-84 type, with other traditionally employed traps: the multiple funnel (Lindgren trap); drainpipe; and slot (Theyson) traps, in a Eucalyptus grandis Hill ex Maiden stand in Brazil. The ESALQ-84 trap was the most efficient in trapping Hypothenemus eruditus Westwood and Hypothenemus obscurus (F.); the multiple funnel trap caught significantly more Cryptocarenus diadematus Eggers; whereas the slot trap caught more Premnobius cavipennis Eichhoff and Xyleborus affinis Eichhoff than the other traps. The drainpipe trap was the least effective trap overall. When corrected for number of beetles caught per trap surface area, catches were significantly higher on the ESALQ-84 trap for the majority of the species analyzed, probably because of a smaller trap surface area. The slot trap was recommended for it caught overall more beetles of the three most economically important scolytid species in eucalypt plantations in Brazil, P. cavipennis, X. affinis, and X. ferrugineus.

La enfermedad de Hodgkin primitiva de pulmon, originada en foliculos linfoides subpleurales, perivasculares o peribronquiales es una excepcion: se conocen aproximadamente 100 casos en la literatura. Por el contrario el compromiso mediastino-pulmonar en el curso de una enfermedad de Hodgkin diseminada tiene una frecuencia que se valora entre un 15 y un 40%, independientemente de la forma histologica Situacion especial son aquellos casos a comienzo mediastino-pulmonar, que no demuestran en estudios de estadificacion posterior participacion extraordinaria.Estos se caracterizan por afectar mujeres en edad media de la vida y por ser histologicamente formas esclero - nodulares.Precisamente hemos de comentar 2 casos recientes que se ajustan a estas condiciones clinico-patologicas
