Primeiro registro de Tomoplagia reimoseri Hendel e Xanthaciura mallochi Aczél (Diptera: Tephritidae) para o Estado de Santa Catarina, Brasil First records of Tomoplagia reimoseri Hendel e Xanthaciura mallochi Aczél (Diptera: Tephritidae) for Santa Catarina state, Brazil

O presente trabalho tem como objetivo levantar as espécies de tefritídeos endófagos associados a capítulos de asteráceas em Chapecó, Santa Catarina. Para tanto, foram efetuadas coletas quinzenais no município de Chapecó, Santa Catarina, durante o período de setembro de 2005 a setembro de 2006, concentradas na primavera e no verão. Os capítulos foram destacados diretamente das plantas, no campo, e acondicionados em sacos plásticos. Este trabalho constitui o primeiro registro de Tomoplagia reimoseri Hendel e Xanthaciura mallochi Aczél coletados em capítulos de Asteraceae no município de Chapecó, elevando para 72 espécies de tefritídeos registradas para o referido Estado.<br>The present research aimed to inventory the species of endophagous tephritids associated to Asteraceae capitula in Chapecó, Santa Catarina. Samples of capitula were collected every two weeks in Chapecó, from september 2005 to september 2006, concentrating efforts on spring and summer. The capitula were collected directly from the plants and conditioned in plastic bags. This research constitutes the first register of Tomoplagia reimoseri Hendel and Xanthaciura mallochi Aczél specimens collected from Asteraceae capitula in Chapecó, elevating to 72 the number of tephritid species registered to the State of Santa Catarina

UV written waveguide devices - Bragg gratings and Applications in Sensors

Ultra-violet laser direct writing provides a powerful way of creating integrated optical devices. The work reported here describes developments in this field, and particularly the use of two-beam writing to create Bragg gratings in planar integrated format. The work shows how these structures can be used in a wide range of applications, ranging from creation of wide-band couplers, through to extremely sensitive sensor devices. UV direct writing removes many of the constraints normally associated with planar integrated optics. It is a mask-free process that uses direct computer control and it dispenses with the etching steps normally required to make low-loss waveguide devices. The work reported will show how this flexibility of format may be combined with novel substrate structures to allow new device types
