Cells and cell-free solutions of the culture filtrate of the bacterial symbiont, Xenorhabdus nematophila taken from the entomopathogenic nematode Steinernema carpocapsae in aqueous broth suspensions were lethal to larvae of the diamondback moth Plutella xylostella. Their application on leaves of Chinese cabbage indicated that the cells can penetrate into the insects in the absence of
the nematode vector. Cell-free solutions containing metabolites were also proved as effective as bacterial cells suspension.
The application of aqueous suspensions of cells of X. nematophila or solutions containing its toxic metabolites to the leaves represents a possible new strategy for controlling insect pests
on foliage. 相似文献

The Safe Schools/Healthy Students (SS/HS) Initiative in Pinellas County, FL, emerged as a part of a broader local effort to implement creative educational and mental health programs to support children and families. This initiative focused on capacity building, prevention, and intervention efforts and comprehensive evaluation to address the barriers to learning and enhance healthy development. This article describes Pinellas County's plan, and highlights the instrumental roles played by school psychologists, which included grant writing, program and resource coordination, clinical services, program evaluation, staff training, parent advocacy, and steering committee membership. Promising outcomes and generalization of these findings to other communities is also discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 489–501, 2003. 相似文献

Low-performing schools in rural settings can face challenges common to all struggling schools, such as low student motivation and maintaining a qualified teaching staff. However, aspects of rural schools’ settings, such as the distance from urban areas and the commute between the schools and the students’ and teachers’ homes, can exacerbate the challenges that rural schools face. This article focuses on the experiences of nine rural schools that were part of a study for the U.S. Department of Education on the school improvement process in a purposive sample of 35 schools receiving federal funds through the School Improvement Grants (SIG) program. In particular, it examines how respondents in the rural schools perceived that the schools’ rural setting influenced the schools’ challenges and improvement actions and presents findings on the recruitment and retention of teaching staff, an activity integral to school improvement efforts under SIG. 相似文献

INTRODUCTION Entomopathogenic nematodes of the generaSteinernema and Heterorhabditis have been used tocontrol a wide range of agriculturally important insectpests (Kaya and Gaugler, 1993). The mechanism bywhich these nematodes are able to infect and repro-duce in the insect host involves a mutual relationshipbetween the nematode and the symbiotic bacteria,Xenorhabdus spp. and Photorhabdus spp. (Akhurstand Dunphy, 1993; Forst and Nealson, 1996). Poinarand Thomas (1966) established tha… 相似文献

This article describes an alternative to the traditional method of administering the comprehensive examination, logically integrated in criminal justice educational program objectives. First, the traditional method of offering the comprehensive examination is evaluated according to its ability to satisfy the educational program goals of developing critical thinking and communication skills together with knowledge of the discipline. Bloom's Taxonomy is used as the paradigm of evaluation. Based upon the examination of available literature and the actual administration of the traditional comprehensive examination at Virginia Commonwealth University, the conclusion is reached that traditional examinations do not test beyond Bloom's first step, knowledge of terminology. The administration of the take-home comprehensive exam is then analyzed as administered at VCU and is found to better serve the educational program objectives of critical thinking and communication skills together with learning knowledge. 相似文献
