Parasitism of Lepidopterous Stem Borers in Cultivated and Natural Habitats
Plant infestation, stem borer density, parasitism, and parasitoid abundance were assessed during two years in two host plants, Zea mays (L.) (Cyperales: Poaceae) and Sorghum bicolor (L.) (Cyperales: Poaceae), in cultivated habitats. The four major host plants (Cyperus spp., Panicum spp., Pennisetum spp., and Sorghum spp.) found in natural habitats were also assessed, and both the cultivated and...
متن کاملRelationships of Reproductive Traits With the Phylogeny of the African Noctuid Stem Borers
The display of the reproductive behavior in most noctuid Lepidoptera follows a diel periodicity and is limited to a precise period of either the day or the night. These behavioral traits and the sex pheromone chemistry can be species specific and thus might be linked to the phylogeny. The objective of this study was to test the relationship of these reproductive traits with phylogeny. The study...
متن کاملDensities of Agrilus auroguttatus and Other Borers in California and Arizona Oaks
We investigated within-tree population density of a new invasive species in southern California, the goldspotted oak borer, Agrilus auroguttatus Schaeffer (Coleoptera: Buprestidae), with respect to host species and the community of other borers present. We measured emergence hole densities of A. auroguttatus and other borers on the lower stem (bole) of naïve oaks at 18 sites in southern Califor...
متن کاملStem cell research: the California experience.
Rarely has a field of biomedical research caught the public imagination as dramatically as stem cell research. The idea of transplanting human cells that have been grown in vitro to replace damaged or diseased tissues and to restore function is easy to understand and is appealing in its concept. Moreover, cell replacement therapy has potentially wide application for scores of diseases ranging f...
متن کاملStem Cell Therapies: California Dreamin'?
Ready or not, stem cells are a step closer to the clinic, thanks to approximately $230 million awarded by CIRM to 14 California-based research groups to develop stem cell-based therapies within 4 years. But, as Kris Novak reports, some of these projects are closer to therapeutic reality than others.
