A systematic survey of Chinese privet foliage, stems, seeds, and roots for associated phy-tophagous insects was conducted in China during 2005 and 2006 in order to establish basic information about the insect communities that Chinese privet harbors and to evaluate the abundance and damage caused by these insects. A total of 170 phytophagous insect species(More)
Mantle biopsy is a means of obtaining tissue samples for genetic, physiological, and contaminant studies of bivalves; but the effects of this biopsy on survival have not been determined. We describe a simple technique for obtaining such samples from unionacean bivalves and how we compared survival among biopsied and control organisms in field experiments.(More)
This study investigated responses of populations of southern flying squirrels to a range of experimental even-aged and uneven-aged timber-harvest practices along a gradient of increasing disturbance intensity. The goals were to determine whether measurable demographic parameters of squirrels in experimental forests would change after logging; whether a(More)
Fallen pine straw (needles) is a renewable biological resource valued as a mulch in horticulture and for landscaping. However, its harvesting may have detrimental long-term effects on forest soils and vegetation. To compare current pine straw harvesting practices, a randomized complete block split-plot study was established during 1990 in a 34-year-old(More)
Effective inactivation of biosafety level 4 (BSL-4) pathogens is vital in order to study these agents safely. Gamma irradiation is a commonly used method for the inactivation of BSL-4 viruses, which among other advantages, facilitates the study of inactivated yet morphologically intact virions. The reported values for susceptibility of viruses to(More)

A BSTRACT Lists of insect species are useful for insect biologists and students in several fields, including taxonomy, behavioral ecology, conservation, and biological control, and they are useful to the teacher of classical entomology for the insight and drama they can provide to the history and biography of our science. Such lists can be viewed as(More)
